Abstract

Background: Venous tumor thrombus (VTT) consistency of renal cell carcinoma (RCC) is an important consideration in nephrectomy plus thrombectomy. However, evaluation of VTT consistency through preoperative MR imaging is lacking. Purpose: To evaluate VTT consistency of RCC through intravoxel incoherent motion‐diffusion weighted imaging (IVIM‐DWI) derived parameters (Dt, Dp, f, and ADC) and the apparent diffusion coefficient (ADC) value. Study Type: Retrospective. Population: One hundred and nineteen patients (aged 55.8 ± 11.5 years, 85 male) with histologically‐proven RCC and VTT who underwent radical resection. Field Strength/Sequences: 3.0‐T; two‐dimensional single‐shot diffusion‐weighted echo planar imaging sequence at 9 b‐values (0–800 s/mm2). Assessment: IVIM parameters and ADC values of the primary tumor and the VTT were calculated. The VTT consistency (friable vs. solid) was determined through intraoperative findings of two urologists. The accuracy of VTT consistency classification based on the individual IVIM parameters of primary tumors and of VTT, and based on models combining parameters, was assessed. Type of operation, intra‐operative blood loss, and operation length were recorded. Statistical Tests: Shapiro–Wilk test; Mann–Whitney U test; Student's t‐test; Chi‐square test; Receiver operating characteristic (ROC) analysis. Statistical significance level was P < 0.05. Results: Of the enrolled 119 patients, 33 patients (27.7%) had friable VTT. Patients with friable VTT were significantly more likely to experience open surgery, have significantly more intraoperative blood loss, and significantly longer operative duration. The area under the ROC curve (AUC) values of Dt of the primary tumor and VTT in classifying VTT consistency were 0.758 (95% CI 0.671–0.832) and 0.712 (95% CI 0.622–0.792), respectively. The AUC value of the model combining Dp and Dt of VTT was 0.800 (95% CI 0.717–0.868). Furthermore, the AUC of the model combining Dp and Dt of VTT and Dt of the primary tumor was 0.886 (95% CI 0.814–0.937). Conclusion: IVIM‐derived parameters had the potential to predict VTT consistency of RCC. Evidence Level: 3 Technical Efficacy: Stage 2 [ABSTRACT FROM AUTHOR]

Abstract

Objectives: To discuss the value of applying magnetic resonance diffusion-weighted imaging (DWI) to evaluate inflammatory activity from chronic viral hepatitis B. Methods: One hundred forty-two patients with chronic viral hepatitis B who received treatment at The Fifth Medical Center of Chinese PLA General Hospital from January 2014 to December 2015 and 20 healthy persons in the control group who were scheduled to undergo nuclear magnetic resonance scanning and DWI examinations (b value = 0, 800 s/mm2), and the apparent diffusion coefficients (ADCs) were measured and compared with the biopsy results of hepatic tissue. Results: The ADC value of the group with hepatitis B was lower than that of the healthy group (P

Abstract

Bladder paraganglioma (BPG) is a rare extra-adrenal pheochromocytoma with variable symptoms and easy to be misdiagnosed and mishandled. The aim of the study was to document the imaging features of BPG using computed tomography (CT) and magnetic resonance imaging (MRI). We retrospectively enrolled consecutive patients with pathology-proven BPG, who underwent CT or MRI examinations before surgery between October 2009 and October 2017. The clinical characteristics, CT, and MRI features of the patients were described and analysed. A total of 16 patients with 16 bladder tumours (median age 51 years, 9 females) were included. Among them, 13 patients underwent CT examinations and eight patients underwent MRI examinations preoperatively. Tumour diameters ranged from 1.6−5.4 cm. Most of the tumours grew into the bladder cavity (n = 11) with oval shapes (n = 10) and well-defined margins (n = 14). Intratumour cystic degeneration or necrosis (n = 2) was observed. Two lesions showed peripheral tissue invasion, suggesting malignant BPGs. All 13 lesions imaged with CT exhibited slight hypoattenuation and moderate to marked enhancement. Compared to the gluteus maximus, all lesions showed slight h yperintensity in T2-weighted images, hyperintensity on diffusion-weighted images (DWI), hypointensity on apparent diffusion coefficient maps, hyperintensity on T1-weighted images and a "fast in and slow out" enhanced pattern on contrast-enhanced MRI images. BPGs are mostly oval-shaped, broadly-based and hypervascular bladder tumours with hypoattenuation on non-contrast CT, T2 hyperintensity, slight T1 hyperintensity compared to the muscle, marked restricted diffusion on DWI. Peripheral tissue invasion can suggest malignancy of the BPGs. All of these features contribute to preoperative decision-making. [ABSTRACT FROM AUTHOR]

Abstract

Purpose: To assess the performance of ADC values in stratifying high- and low-risk groups of Gleason score of prostate cancer. Materials and methods: 370 cases of prostate cancer who met the selection criteria between October 2015 and May 2019 were collected in the study. MRI sequences included high-resolution transverse T2WI and DWI (b= 0, 1000, 2000 and 3000 s/mm2). Surgical pathological results were obtained in all cases. The ADC values of prostate cancer lesions were measured by two radiologists and the consistency and reproducibility analysis were done. The ADC values were compared between high-risk group and low-risk group lesions and the receiver operating characteristic (ROC) curve was used to evaluate the value of ADC values of different bvalues in distinguishing high-risk group from low-risk group of Gleason of prostate cancer. Results: The consistency and reproducibility of ADC values measured by two radiologists in high- and low-risk group of Gleason of prostate cancer were excellent. The ADC values for high-risk group of Gleason of prostate cancer were significantly lower than those for low-risk group (p&lt; 0.05). The area under the ROC curve (AUC) of different bvalues distinguishing high-risk group from low-risk group of Gleason of prostate cancer were 0.651, 0.656, 0.692 (reader1) and 0.658, 0.653, 0.695 (reader2), respectively. The diagnostic efficacy of bvalue (3000 s/mm2) is the highest. Conclusions: The bvalue of 3000 s/mm2is the most useful in differentiating high-risk group from low-risk group of Gleason of prostate cancer.
