Abstract Objective To evaluate the efficacy of multiparametric magnetic resonance/transrectal ultrasound fusion (MRI/TRUS fusion) biopsy versus systematic biopsy and its association with PI-RADS v2 categories in patients with suspected prostate cancer. Materials and methods 122 patients undergoing both MRI/TRUS fusion and systematic biopsy, with suspicion...

Abstract Purpose Deep learning reconstruction (DLR) introduces deep convolutional neural networks into the reconstruction flow. We examined the clinical applicability of drip-infusion cholangiography (DIC) acquired on an ultra-high-resolution CT (U-HRCT) scanner reconstructed with DLR in comparison to hybrid and model-based iterative reconstruction (hybrid-IR, MBIR). Methods...

Abstract Purpose To compare the detectability of pancreatic ductal adenocarcinoma (PDAC) and liver metastases between Gd-EOB-DTPA- and extracellular contrast materials (ECCMs) contrast-enhanced MR imaging contrast. Methods Two hundred seventy-two patients with suspected pancreatic disease underwent Gd-EOB-DTPA-enhanced MR imaging (EOB group, n = 79) or ECCMs-enhanced...

Abstract Prostate MRI has seen increasing interest in recent years and has led to the development of new MRI techniques and sequences to improve prostate cancer (PCa) diagnosis which are reviewed in this article. Numerous studies have focused on improving image quality (segmented DWI) and faster acquisition (compressed sensing, k-t-SENSE, PROPELLER). An increasing number of studies have developed new quantitative and computer-aided diagnosis methods including artificial intelligence...

Abstract Definitive therapy for prostate cancer includes radical prostatectomy and radiation therapy. Treatment is elected based on patient preference, biological tumor factors, and underlying health. Post prostatectomy, men are surveyed for disease recurrence with serial PSA measurements, digital rectal exam, and imaging studies depending on nomogram predicted risk of local disease recurrence and distant metastasis. In men with rising PSA levels, pathologically incomplete surgical...

Abstract A 70-year-old woman has been followed up for chronic hepatitis C and hepatocellular carcinoma which had been successfully controlled by several sessions of radiofrequency ablation. A small cystic lesion in segment IV associated with adjacent intrahepatic duct dilatation was firstly noted 4 years before on MR imaging, which showed gradual increase in size and significant interval change in the MRI signal intensity of the cystic content on the follow-up examinations. The...

Abstract Objective To assess the clinical efficacy and safety of computed tomography-guided radiofrequency ablation(CT-RFA) combined with transarterial embolization(TAE) assisted by a three-dimensional visualization ablation planning system(3DVAPS) for hepatocellular carcinoma(HCC) in challenging locations. Methods Data from 62 treatment-naive...

Abstract Purpose To investigate the impact of the different access for percutaneous transhepatic biliary drainage (PTBD) in terms of “Quality of Life” (QoL) in the management of malignant obstructive jaundice. Methods In this IRB-approved study, 64 consecutive patients with malignant obstructive jaundice were prospectively randomized to the...

Abstract Purpose To survey Society of Abdominal Radiology Crohn’s Disease (CD) Disease-Focused Panel (DFP) members to understand state-of-the-art CT/MR enterography (CTE/MRE) protocols and variability between institutions. Methods This study was determined by an institutional review board to be “exempt” research. The survey consisted of 70 questions...

Abstract Purpose To determine whether staging pelvic magnetic resonance imaging (MRI) can distinguish malignant mixed Müllerian tumor (MMMT) from EC. Methods Thirty-seven treatment-naïve patients with histologically proven uterine MMMT and 42 treatment-naïve patients with EC, treated at our institution, were included in our retrospective study....
