CT-Value (△HU and CT-Value ratioin) differential diagnosis of small hepatocellular carcinoma from focal nodular hyperplasia
Background: The objective was to explore the value of the CT value difference (△HU) and CT value ratio (CVR) between the hepatic arterial (AP), portal (PP), and delayed phases (DP) to differentiate the small Hepatocellular Carcinoma (SHCC, ≤ 3 cm) from the small Focal nodular hyperplasia (SFNH, ≤ 3 cm). Materials and Methods: All the lesions were confirmed by clinically and/or pathologically an...
متن کاملDetection of hypervascular hepatocellular carcinoma: comparison of SPIO-enhanced MRI with dynamic helical CT.
PURPOSE The purpose of this study was to compare the diagnostic performance of superparamagnetic iron oxide (SPIO)-enhanced MRI for the detection of hypervascular hepatocellular carcinoma (HCC) with dynamic helical CT. METHODS SPIO-enhanced MR and dynamic helical CT images obtained from 41 patients with 52 hypervascular HCCs (5-130 mm; mean, 27 mm) were retrospectively analyzed. MRI were obta...
متن کاملThe Predictive Value of Abdominal Ultrasonography Compared to CT Scan for the Evaluation of Pediatric Lymphoma
Background: Given the children's susceptibility to the harmful radiation of computerized tomography (CT) scans, ultrasonography can be a good alternative in staging pediatric lymphoma. The present study aimed to assess the predictive value of abdominal ultrasonography compared to CT scan in children with lymphoma. Materials and Methods: Fifty-two children with confirmed lymphoma were included ...
متن کاملDetection of Small Hypervascular Hepatocellular Carcinomas in Cirrhotic Patients: Comparison of Superparamagnetic Iron Oxide-Enhanced MR Imaging with Dual-Phase Spiral CT
OBJECTIVE To compare the performance of superparamagnetic iron oxide (SPIO)-enhanced magnetic resonance (MR) maging at 1.5T and dual-phase spiral computed tomography (CT) for the depiction of small hypervascular hepatocellular carcinomas (HCCs). MATERIALS AND METHODS Forty-three patients with 70 small nodular HCCs (5-20 mm; mean, 13.7 mm) were examined. Diagnosis was based on the results of s...
