To retrospectively evaluate findings of chemotherapy-induced focal hepatopathy (CIFH) on gadoxetic acid-enhanced magnetic resonance (MR) and diffusion-weighted (DW) images to determine imaging features that are most helpful in differentiating CIFH from metastasis.This retrospective study was approved by the institutional review board, informed consent waived. MR images, including DW 12 patients (four men, eight women; age range, 25-64 years) with 15 CIFHs were reviewed independently...
Purpose To evaluate the natural history and contrast material–enhanced computed tomographic (CT) features of postoxaliplatin heterogeneity liver parenchyma (POHL) to investigate association POHL with clinical factors biomarkers sinusoidal obstruction syndrome (SOS). Materials Methods The retrospective study was approved by institutional review board, informed consent waived. Two hundred seventy patients (159 men, 111 women; age range, 31–92 years) who underwent oxaliplatin-based chemotherapy...
We aimed to investigate the efficacy of computer-aided detection (CAD) for MRI in assessment tumor extent, lymph node status, and multifocality invasive breast cancers comparison with other imaging modalities.Two radiologists measured maximum size, as well as, analyzed status 86 patients using mammography, ultrasound, CT, without CAD, 18-fludeoxyglucose positron emission tomography (FDG-PET). The assessed data were compared pathology.For there no significant differences between pathological...
Background Identification of clinical features to determine the aggressive potential tumors is highly warranted stratify patients for adequate treatment. Computed tomography (CT) imaging clear cell renal carcinoma (ccRCC) may contribute personalized risk assessment. Purpose To assess correlation between CT and Fuhrman grade ccRCC, identify predictors high in conjunction with tumor size. Material Methods scans 169 173 pathologically proven ccRCCs were retrospectively reviewed consensus by two...
Background: Breast cancer is a heterogeneous disease with diverse prognoses. The main prognostic determinants are lymph node status, tumor size, histological grade, and biological factors, such as hormone receptors, human epidermal growth factor receptor 2 (HER2), Ki-67 protein levels, p53 expression. Diffusion-weighted imaging (DWI) can be used to measure the apparent diffusion coefficient (ADC) that provides information related cellularity integrity of cell membranes. Objectives: goal this...
Institutional review board approval and informed consent were obtained. The purpose of the study was to prospectively evaluate magnetic resonance (MR) urethrography for depiction obliterative urethral stricture. Twelve patients with stricture examined preoperatively T2-weighted, T1-weighted, contrast material–enhanced T1-weighted MR imaging a urethra distended sterile lubricating jelly. Ten 12 conventional retrograde (RGU) combined voiding cystourethrography (VCUG) prior imaging. Each result...
In preoperative assessment of breast cancer, MRI has been shown to identify more additional lesions than are detectable using conventional imaging techniques. The characterization is important detection for optimal surgical treatment. Additional can be included in focus, mass, and non-mass enhancement (NME) on MRI. According the fifth edition reporting data system (BI-RADS®), which includes several changes NME descriptors, few studies date have evaluated cancer.We investigated diagnostic...
Loss or reduced E-cadherin expression and aberrant of N-cadherin have been associated with invasiveness human carcinoma cells poor prognosis. The role E- N-cadherin, however, in hepatocellular (HCC) has not yet elucidated. aim the present study was to investigate pattern surgically resected HCC specimens according their relationship clinicopathological features. patterns were evaluated on immunohistochemistry 68 adjacent non-tumor tissue. most different between tissue decreased staining...
Objective: To help preserve accessory pudendal arteries (APAs) and to ensure optimal postoperative sexual function after a laparoscopic or robot-assisted radical prostatectomy, we have evaluated the incidence of APAs as detected on multidetector-row CT (MDCT) angiography provided detailed anatomical description. Materials Methods:The distribution was in 121 consecutive male patients between February 2006 July 2007 who underwent 64channel MDCT lower extremities.We defined an APA any artery...
Introduction Although fluoroscopically guided procedures involve a considerably high dose of radiation, few studies have investigated the effects radiation on medical workers involved in interventional fluoroscopy procedures. Previous research remains early stages and has not reached level comparable with other occupational thus far. Furthermore, study provides an opportunity to estimate health risks at low doses rates ionising radiation. Therefore, objectives this are (1) initiate...
Rationale: Ectopic variceal bleeding is a rare (2–5%) but fatal gastrointestinal bleed in patients with portal hypertension. Patients ectopic manifest melena, hematochezia, or hematemesis, which require urgent managements. Definitive therapeutic modalities of varices are not yet standardized because low incidence. Various have been applied on the basis experiences experts availability facilities, varying results. Patient concerns: We encountered eight cases five last years. Diagnoses: All...
Cystic Brunner's gland hamartoma in the duodenum is exceedingly rare, although microscopic examination may sometimes reveal a containing dilated ducts duodenum.We present case of large cystic with long stalk, which described light multidetector-row computed tomography, magnetic resonance imaging, and modified small bowel series, together pathologic correlation differential diagnosis.

To evaluate the diagnostic performance of contrast material-enhanced magnetic resonance (MR) angiography for preoperative detection and localization accessory pudendal arteries (APAs) in patients with prostate cancer.This prospective study was approved by institutional review board, informed consent obtained. Between July 2007 December 2010, 127 underwent contrast-enhanced MR following imaging at 3.0 T before robot-assisted laparoscopic radical prostatectomy (RALP). APAs were defined as any...
