Interobserver reproducibility in evaluating the severity of bowel inflammation in CD using the MaRIA score can be improved by modification with DWI. MaRIA scoring provides steady results across enteric and portal phases.

Post-ischemic strictures develop in the ileum, jejunum and colon after an interval of several weeks. In the colonic segment, strictures mainly occur in the "watershed zone." Typical CT findings include a single area of concentric wall thickening of medium length (mean, 7.4 cm), with moderate and higher enhancement in portal phase and vasa recta prominence.

BACKGROUND: The imaging features of pleural tuberculosis (PTB) can be similar to those of malignant pleural dissemination (MPD) with several case reports of CT findings in atypical presentations of PTB. PURPOSE: To describe the computed tomography (CT) features of PTB by comparing these imaging findings with those of MPD and to use the results to differentiate between the two diseases. MATERIAL AND METHODS: The study included 135 patients with PTB and 69 with MPD. The CT images were assessed in

OBJECTIVES: To evaluate the accuracy and safety of repeated ultrasound-guided core needle biopsy (CNB) for hepatic focal lesions and to assess the predictive factors for success of repeated CNB. METHODS: For 5 years, 3085 CNBs were performed for focal hepatic lesions using an automated biopsy gun with an 18-gauge needle. Seventy-eight patients underwent repeated CNB because of pathologically inconclusive or unexpected results. Twelve patients were excluded because of unavailable additional tissu

The purpose of this study was to compare the diagnostic performance of computed tomography angiography (CTA) and contrast-enhanced ultrasound (CEUS) when used to diagnose significant hepatic artery occlusion (HAO) in patients that was suspected on Doppler ultrasound (US). Among 3465 adult liver transplantations (LTs) performed between January 2010 and February 2018, 329 recipients were suspected of having HAO by Doppler US. In these patients, 139 recipients who had undergone both CTA and CEUS as

BACKGROUND: Early detection of breast cancer reduces mortality. Therefore, diagnosis of ductal carcinoma in situ (DCIS) is important. PURPOSE: To compare the sensitivities of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and breast-specific gamma imaging (BSGI) in pathologically proven calcified and non-calcified DCIS. MATERIAL AND METHODS: Thirty-five patients with pathologically diagnosed DCIS from 1 June 2009 through 31 December 2011, underwent a protocol involving both breas

BACKGROUND: Knowing the lowest acceptable radiation dose of multiphase hepatic CT may allow us to reduce the radiation dose for detecting HCC. PURPOSE: To prospectively assess the image quality and diagnostic performance of low-dose and ultra-low-dose multiphase hepatic computed tomography using a dual-source CT scanner. METHODS: Three reconstructed different dose scan images (standard-dose, low-dose, and ultra-low-dose) of hepatic multiphase CT were obtained from 67 patients with a dual-source
