AIM To investigate the correlation between microvessel density and spiral CT perfusion imaging in colorectal carcinoma. METHODS Thirty-seven patients, with histologically proven colorectal carcinoma, underwent water enema spiral CT scan. The largest axial surface of the primary tumor was searched on unenhanced spiral CT images. At this level, the enhanced(More)
To evaluate the correlation between 64 multidetector-row CT (64MDCT) perfusion imaging in colorectal carcinoma and microvessel density (MVD) and vascular endothelial growth factor (VEGF), 64MDCT perfusion imaging was performed in 33 patients with pathologically verified colorectal carcinoma. These images were analyzed with perfusion functional software, and(More)
BACKGROUND Crohn's disease and intestinal tuberculosis (ITB) are chronic granulomatous disorders that are difficult to distinguish. Computed tomographic enterography (CTE) yields striking findings for Crohn's disease in the small bowel but its role in differentiating Crohn's from ITB is undefined. This prospective study aimed to investigate the value of CTE(More)
OBJECTIVE To measure the radiation dose from CT scans in an anthropomorphic phantom using a 64-slice MDCT, and to estimate the associated cancer risk. MATERIALS AND METHODS Organ doses were measured with a 5-year-old phantom and thermoluminescent dosimeters. Four protocols; head CT, thorax CT, abdomen CT and pelvis CT were studied. Cancer risks, in the(More)
AIM This study aims to analyze computed tomography (CT) and magnetic resonance (MR) imaging features of infantile hepatic hemangioendotheliomas before and after treatment. MATERIALS AND METHODS CT and MR examinations of seven infants with biopsy proven hepatic hemangioendotheliomas were retrospectively analyzed. The distribution, number, size, imaging(More)
BACKGROUND Ileocolonoscopy is the gold standard to assess postoperative recurrence (POR) in patients with Crohn's disease (CD) who have undergone ileocolic resection. Although computed tomographic enterography (CTE) yields striking findings in the small bowel of CD, its role in POR is undefined. The aim of this study was to compare ileocolonoscopy and CTE(More)
PURPOSE To evaluate effect of liver function on biliary system visualization using gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance cholangiography (CE-MRC). MATERIALS AND METHODS In all, 39 patients were divided into three groups according to their Child-Pugh classification: group A, Child-Pugh class A(More)
BACKGROUND Fecal calprotectin (FC) levels have been extensively reported to correlate with clinical and endoscopic activities in Crohn's disease (CD); however, the utility of FC levels in the postoperative setting remains to be determined. Using meta-analysis, we aimed to evaluate the utility of FC as a noninvasive marker of recurrence in patients with CD(More)
OBJECTIVE This study aimed to investigate Multidetector Computed Tomography (MDCT) manifestations of the normal duodenal papilla, thereby improving the knowledge on the CT manifestations of the normal anatomy of the duodenal papilla. METHODS A retrospective study was conducted by reviewing the CT results of 70 normal duodenal papilla cases examined by(More)
We aimed to evaluate the multi-slice computed tomography (MSCT) features of pancreatic neuroendocrine neoplasms (P-NENs) and analyse the correlation between the MSCT features and pathological classification of P-NENs. Forty-one patients, preoperatively investigated by MSCT and subsequently operated on with a histological diagnosis of P-NENs, were included.(More)
