Background: To clarify multidetector computed tomography (MDCT) findings of attenuated plaque detected by intravascular ultrasound (IVUS). Methods and Results: One hundred and fifty-four patients with stable angina underwent MDCT before IVUS. The attenuated plaque was identified in the targeted artery with IVUS, and the same artery was analyzed with MDCT for the presence of a high density area (HDA) >130 Hounsfield units (HU), and a low density area (LDA) <30 HU. A HDA in attenuated plaque was compared with that in calcified plaque. Ten attenuated plaques and 15 calcified plaques were identified in 9 of 154 patients (males=9, 66.2±9.5 years). Eight of the 10 attenuated plaques and all 15 calcified plaques were accompanied with a HDA on MDCT. The HDA ranged from 174 to 667 HU (mean 389.0±148.3 HU) in the 8 attenuated plaques, and from 545 to 1,205 HU (mean 920.9±215.9 HU) in 15 calcified plaques. There was a significant difference in CT density of the HDA between the attenuated and calcified plaque (P<0.001). All attenuated plaques contained LDA <30 HU in the portions without HDA. Conclusions: MDCT has the ability to demonstrate attenuated plaque as the combination of HDA (approximately 400 HU on average) and LDA <30 HU. The HDA can be differentiated from calcified plaque by its lower CT density value.

OBJECTIVE. The purpose of our study was to evaluate the utility of diffusion-weighted MRI (DWI) for preoperative T categorization and prediction of the histopathologic grade of renal pelvic cancer. MATERIALS AND METHODS. We retrospectively evaluated 40 renal pelvic cancers from 40 patients. The MRI included T2-weighted single-shot fast spin-echo, DWI, and contrast-enhanced imaging. Two radiologists independently reviewed three image sets (T2- weighted images alone, T2-weighted plus DWI, and T2-weighted plus contrast-enhanced images) regarding tumor detection and the discrimination of locally advanced tumors. The diagnostic performance among the three image sets were compared using Cochrane test followed by McNemar tests. The apparent diffusion coefficients between two histopathologic grades were compared using the Mann-Whitney U test. RESULTS. T2-weighted imaging plus DWI enabled a high detection rate (98%, 39/40) without significant differences. For the diagnosis of T3 or higher categories, the accuracies were relatively low in all three image sets (70% each for T2-weighted imaging plus DWI and T2-weighted imaging plus contrast-enhanced imaging and 58% for T2-weighted imaging alone, p > 0.05), with sensitivities of 58%, 65%, and 54%, respectively. For discriminating tumors with macroscopic renal invasion from those with microscopic renal invasion or less, T2-weighted imaging plus DWI (93%) was significantly more accurate than T2-weighted imaging alone (75%) (p = 0.016). The mean apparent diffusion coefficient of the high-grade tumors was significantly lower than that of the low-grade tumors (p < 0.01). CONCLUSION. DWI could be used for preoperative T categorization and prediction of the histopathologic grade of renal pelvic cancer without contrast material. © American Roentgen Ray Society.

The purpose of this study was to evaluate whether experimental fine-cell detector computed tomography with a 0.3125 mm cell (0.3 mm cell CT) can improve the detection of coronary vessel walls compared with conventional 64-slice computed tomography with a 0.625 mm cell (0.6 mm cell CT). A coronary vessel wall phantom was scanned using 0.6 mm cell CT and 0.3 mm cell CT. The data for 0.3 mm cell CT were obtained using four protocols: a radiation dose equal, double, triple or quadruple that were used in the 0.6 mm cell CT protocol. The detectable size of the vessel wall was assessed based on the first and second derivative functions, and the minimum measurable values were compared using a paired t-test. As a result, the minimum detectable wall thickness of 0.6 mm cell CT (1.5 mm) was significantly larger than that of 0.3 mm cell CT performed using the triple- and quadruple-dose protocols (0.9 mm) and the double-dose protocol (1.1 mm). The difference in the minimum detectable vessel wall thickness measured using 0.6 mm cell CT (1.5 0.1 mm) and 0.3 mm cell CT (0.9 0.1 mm, 1.1 0.2 mm) was significant (p < 0.01). We concluded that 0.3 mm cell CT improved the detection of coronary vessel walls when a more than double-dose protocol was used compared with 0.6 mm cell CT. © 2011 Institute of Physics and Engineering in Medicine.

Objective: The purpose of this study was to compare the accuracy of CT urography and excretory urography for the detection and localization of upper urinary tract urothelial carcinoma. Materials and Methods: Of 128 patients at high risk for upper tract urothelial carcinoma who were examined with both CT urography and excretory urography between 2002 and 2007, 24 were undiagnosed and excluded. CT urography and excretory urography results of the remaining 104 patients and 552 urinary tract segments were compared with histopathologic examination or follow-up imaging at 1 year. Two readers independently scored the confidence levels for the presence or absence of upper urinary tract urothelial carcinoma in each of six upper urinary tract segments on both CT urography and excretory urography; differences were resolved by consensus. Results: Upper urinary tract urothelial carcinoma was diagnosed in 77 (14%) segments of 46 (44%) patients. Per-patient sensitivity, specificity, overall accuracy, and area under the receiver operating characteristic curves for detecting carcinomas with CT urography (93.5% [43/46], 94.8% [55/58], 94.2% [98/104], and 0.963, respectively) were significantly greater than those for excretory urography (80.4% [37/46], 81.0% [47/58], 80.8% [84/104], and 0.831, respectively) (p = 0.041, p = 0.027, p = 0.001, and p < 0.001, respectively). Persegment sensitivity and overall accuracy for the localization of upper urinary tract urothelial carcinoma were significantly greater with CT urography (87.0% [67/77] and 97.8% [540/552]) than with excretory urography (41.6% [32/77] and 91.5% [505/552]) (p < 0.0001). Conclusion: CT urography was more accurate than excretory urography in the detection and localization of upper urinary tract urothelial carcinoma and should be considered as the initial examination for the evaluation of patients at high risk for upper urinary tract urothelial carcinoma.

Purpose: We analyzed the prognostic impact of hydronephrosis grade on disease specific survival and evaluated whether hydronephrosis grade could preoperatively predict worse pathological outcomes in cases of upper tract urothelial carcinoma treated surgically. Materials and Methods: We identified and retrospectively reviewed the records of 91 patients who were evaluated by multidetector computerized tomography and/or magnetic resonance imaging preoperatively, and treated with nephroureterectomy at our institution from 2000 to 2009. Ipsilateral hydronephrosis was graded 0 to 4 by 2 urological radiologists blinded to clinical outcomes. We analyzed the associations between hydronephrosis grade, and pathological findings and patient outcomes. Results: Preoperatively 67 patients (73.6%) had ipsilateral hydronephrosis. Grade was 1 to 4 in 3 (3.3%), 17 (18.7%), 23 (25.3%) and 24 cases (26.4%), respectively. Higher hydronephrosis grade was significantly associated with a ureteral tumor (p = 0.0307), higher pT stage (p = 0.0002) and lymphovascular invasion (p = 0.0014). Higher hydronephrosis grade was not associated with disease specific or metastasis-free survival. On preoperative multivariate analysis high hydronephrosis grade predicted pathological T stage (T3 or greater) (HR 4.98, p = 0.0228), positive lymphovascular invasion (HR 6.37, p = 0.0022) and grade 3 (HR 2.98, p = 0.0311). Conclusions: On image analysis preoperative hydronephrosis grade was associated with features of aggressive disease and predicted an advanced pathological outcome in patients with upper tract urothelial carcinoma. This information could prove useful to select candidates for neoadjuvant chemotherapy and make decisions concerning surgical options. © 2011 American Urological Association Education and Research, Inc.

Radiation exposure in Cardiac CT

Tanami Y., Jinzaki M., Kuribayashi Y.

Japanese Journal of Clinical Radiology （Japanese Journal of Clinical Radiology） 56 （ 1 ） 19 - 28 2011年01月

研究論文（学術雑誌）, 共著, ISSN 0009-9252

Cardiac computed tomography angiography (CCTA) has emerged as a useful diagnostic imaging modality in the assessment of coronary artery disease. However, the potential risks due to exposure to ionizing radiation associated with CCTA have raised concerns. Several techniques such as "lower kVp", "step and shoot method" and "interative reconstruction" significantly reduce radiation dose without impairing image quality when compared with the standard retrospective helical data acquisition. These effective strategies to reduce radiation dose are available but some strategies are not frequently used. It is important to increase the use of dose-saving strategies in adequately selected patients.

A 68-year-old man underwent total cystectomy, urethrectomy preserving fossa naviculars, and an Indiana pouch urinary diversion in 1997. The histopathology was UC, G3, pT4 (prostate). Nine years after the operation, he had multiple metastases to the inguinal and paraaortic lymph nodes (LNs), and he complained of erosion around the glans. Histological diagnosis of the glans revealed recurrent UC to the urethra of the glans. We considered the possibility that the inguinal LN metastasis was due to lymphatic spread from a remnant urethral recurrence. Thus, a partial penectomy and inguinal LN dissection were undertaken. Systemic chemotherapy was administered. Remnant urethral recurrence after urethrectomy preserving the fossa navicularis and inguinal LN metastasis are rare. © 2011 Japanese Urological Association.

研究論文（学術雑誌）, 共著, ISSN 1867-1071

Purpose: The aim of this study was to assess the body weight-tailored contrast material injection protocol for 64-detector computed tomography (CT) to maintain optimal coronary CT attenuation. Materials and methods: A total of 60 patients who underwent CT coronary angiography were assigned to one of three groups: protocol A, total of 0.7 ml kg-1 with 300 mg I/ml iodine concentration; protocol B, total of 0.6 ml kg-1 with 350 mg I/ml; protocol C, total of 0.7 ml kg-1 with 350 mg I/ml. The injection duration was 10 s in all patients. The proportion of intracoronary attenuation values >325 HU was compared on a pervessel and per-patient basis. Results: The attenuation value was significantly more likely to exceed 325 HU with protocol C (95% for reader 1 and 90% for reader 2) than with protocol A or B on the per-vessel analysis (P < 0.05). The attenuation value also signifi cantly exceeded 325 HU with protocol C (95% and 90%, respectively) more often than with protocol A or B on the per-patient analysis (P < 0.05). Conclusion: A total of at least 0.7 ml kg-1 contrast material with 350 mg/ml iodine concentration is required to achieve optimal coronary CT attenuation (>325 HU) with 64-detector CT when using an injection duration of 10 s. © 2011 Japan Radiological Society.

Objectives: To evaluate the diagnostic performance of fast scanning tomosynthesis in comparison with that of chest radiography for the detection of pulmonary nodules, using multidetector-row computed tomography (MDCT) as the reference, and to assess the association of the true-positive fraction (TPF) with the size, CT attenuation value, and location of the nodules. Materials and methods: The institutional review board approved this study, and written informed consent was obtained from all patients. Fifty-seven patients with and 59 without pulmonary nodules underwent chest MDCT, fast scanning tomosynthesis, and radiography. The images of tomosynthesis and radiography were randomly read by 3 blinded radiologists; MDCT served as the reference standard. Free-response receiver-operating characteristic (FROC) and receiver-operating characteristic (ROC) analyses, Cochran-Armitage trend or Fisher exact test, a conditional logistic regression model, and McNemar test were used. Results: Both FROC and ROC analyses revealed significantly better performance (P < 0.01) of fast scanning tomosynthesis than radiography for the detection of pulmonary nodules. For fast scanning tomosynthesis, the average TPF and false-positive rate as determined by FROC analysis were 0.80 and 0.10, respectively. For both fast scanning tomosynthesis and radiography, the average TPF increased with increasing nodule size and CT attenuation values, and was lower for subpleural nodules (all P < 0.01). Conclusions: The diagnostic performance of fast scanning tomosynthesis for the detection of pulmonary nodules was significantly superior to that of radiography. The TPF was affected by the size, CT attenuation value, and location of the nodule, in both fast scanning tomosynthesis and radiography. © 2011 Lippincott Williams & Wilkins.

Virtual monochromatic spectral imaging with fast kilovoltage switching: Improved image quality as compared with that obtained with conventional 120-kVp CT

Matsumoto K., Jinzaki M., Tanami Y., Ueno A., Yamada M., Kuribayashi S.

Radiology （Radiology） 259 （ 1 ） 257 - 262 2011年

研究論文（学術雑誌）, 共著, ISSN 0033-8419

Purpose: To compare image quality obtained in phantoms with virtual monochromatic spectral (VMS) imaging with that obtained with conventional 120-kVp computed tomography (CT) for a given radiation dose. Materials and Methods: Three syringes were filled with a diluted contrast medium (each syringe contained a contrast medium with a different iodine concentration [5, 10, or 15 mg of iodine per milliliter]), and a fourth syringe was filled with water. These syringes were placed in a torso phantom meant to simulate the standard human physique. The phantom was examined with a CT system and use of the fast kilovoltage switching (80 and 140 kVp) and conventional (120 kVp) modes. Image noise and contrast-to-noise (CNR) ratio were analyzed on VMS images and 120-kVp CT images. Results: Image noise on VMS images in the range of 67-72 keV was significantly lower than that on the 120-kVp CT images (P < .014). Image noise was lowest at 69 keV and was 12% lower when compared with that on 120-kVp CT images. CNR on the VMS images was highest at 68 keV. CNR on the VMS images obtained at 68 keV in the syringes filled with diluted contrast material (5, 10, and 15 mg of iodine per milliliter) was 28%, 31%, and 30% higher, respectively, compared with that on the 120-kVp CT images (P < .001). Conclusion: VMS imaging at approximately 70 keV yielded lower image noise and higher CNR than did 120-kVp CT for a given radiation dose. VMS imaging has the potential to replace 120-kVp CT as the standard CT imaging modality, since optimal VMS imaging may be expected to yield improved image quality in a patient with standard body habitus. © RSNA, 2011.

Evaluation of In-Stent Restenosis by High Spatial Resolution CT

Jinzaki M., Yamada M., Tanami Y., Kuribayashi S.

Multidetector row CT has been established as a noninvasive method for the detection of coronary artery disease. In previous studies, the diagnostic accuracy of 64-slice CT for the detection of in-stent restenosis usually displayed high sensitivity and negative predictive value, while specificity and positive predictive values were too low to allow its utilization in clinical practice. Especially in small stents-with a diameter below 3. 0 mm-the accuracy of CT angiography to detect in stent stenosis has been low. Recently, CT systems with improved in-plane spatial resolution (high-definition CT, HDCT) have become commercially available. Furthermore, an experimental CT (fine-cell detector CT, FDCT) has been developed using half pitch dimension detector cells in both X and Z directions compared with 64-slice CT. Compared with that in conventional 64-slice CT, the spatial resolution was 30% improved in HDCT and 60% improved in FDCT, and the lumen visibility was 1. 3 times improved in HDCT and 1. 5 times improved in FDCT. The diagnostic accuracy of in-stent restenosis with HDCT was higher than 90% in both sensitivity and specificity, moderate (77%) in positive predictive value, and very high (98%) in negative predictive value. FDCT is not yet applicable to patients, however, further improvement of diagnostic accuracy in the evaluation of in-stent restenosis is expected in FDCT. In the near future, cardiac CT could reach the diagnostic performance to replace invasive catheter angiography, and would be the appropriate noninvasive technique for diagnosis of in-stent restenosis. © 2011 Springer Science+Business Media, LLC.
