To determine the added value of hepatobiliary phase images in gadoxetic acid-enhanced magnetic resonance (MR) imaging evaluation hepatocellular carcinoma (HCC).Institutional review board approved this retrospective study and waived informed consent. Fifty-nine patients with 84 HCCs underwent MR examinations that included 20-minute delayed imaging. was performed a 1.5-T system 19 3.0-T 40 patients. A total 113 hepatic nodules were documented for analysis. Three radiologists independently...
Purpose To identify magnetic resonance (MR) imaging features that enable prediction of early recurrence (<2 years) after curative resection hepatocellular carcinoma (HCC) and to derive a preoperative model. Materials Methods This retrospective study was approved by the institutional review board. The requirement obtain written informed consent waived. A total 268 patients who underwent hepatic for single HCC from January 2008 August 2011 were divided into two cohorts: training cohort, which...
To determine whether peritumoral hypointensity seen on hepatobiliary phase images of preoperative gadoxetate disodium-enhanced magnetic resonance imaging (EOB-MRI) is useful for predicting microvascular invasion hepatocellular carcinoma (HCC).This study was approved by the Institutional Review Board. In all, 104 HCC masses in patients who had undergone EOB-MRI and liver surgery within 1 month after were evaluated. Two radiologists independently recorded presence a phase. Interobserver...
Purpose We obtained intravoxel incoherent motion (IVIM) parameters through biexponential analysis on diffusion‐weighted MR imaging (DWI) using multiple b values. Correlation was evaluated between these and histological microvessel density (MVD) for the possibility of noninvasive evaluation MVD with DWI. Methods Twenty‐five nude mice HT29 colorectal cancer cells implanted were analyzed after undergoing DWI values (0, 50, 100, 300, 500, 700, 1000 s/mm 2 ). Tissue diffusivity ( D t ),...
This paper proposes a sinogram-consistency learning method to deal with beam hardening-related artifacts in polychromatic computerized tomography (CT). The presence of highly attenuating materials the scan field causes an inconsistent sinogram that does not match range space Radon transform. When mismatched data are entered into during CT reconstruction, streaking and shading generated owing inherent nature inverse transform METHODS: proposed aims repair by removing primary metal-induced...
Abstract Purpose: To retrospectively compare the diagnostic accuracy for detection of colorectal liver metastases between gadoxetic acid‐enhanced MRI (EOB‐MRI) and diffusion‐weighted imaging (DWI) on 3.0 Tesla (T) system, then to determine whether a combination two techniques may improve performance. Materials Methods: Forty‐seven patients underwent MR at 3.0T, including DWI (DWI set) dynamic hepatobiliary phase EOB‐MRI (EOB preoperative evaluation metastases. All suspicious were confirmed...
The objective of our study was to determine the feasibility using Metal Artifact Reduction (MAR) software for abdominopelvic dual-energy CT in patients with metal hip prostheses.This retrospective included 33 (male-female ratio, 19:14; mean age, 63.7 years) who received total replacements and 20 did not have prostheses as control group. All underwent CT. quality images reconstructed MAR algorithm those standard reconstruction evaluated terms visibility bladder wall, pelvic sidewall, rectal...
The purpose of this study was to compare the diagnostic performance MRI and endoscopic ultrasound (EUS) for characterization cystic pancreatic lesions prediction malignancy.Fifty patients (24 women 26 men; average age, 57 years) underwent both EUS. All (21 29 solid lesions) were proven by histopathologic analysis. Two radiologists retrospectively examined MR images, a single gastroenterologist reviewed EUS images. characterizations morphologic features predictions malignancy evaluated. done...
Background: Fruits of Morus alba L. (mulberry) have various bioactive compounds such as polyphenols and anthocyanins used a herbal medicine. However, the anti-cancer effects molecular basis not been elucidated. Methods: We isolated cyanidin-3-glucoside in cultivar mulberry by acidified-methanol extraction methods. This molecule were compared mass spectroscopic properties LC-MS/MS analyzed 1H 13C NMR. examined effect with mechanisms on MDA-MB-453 human breast cancer cells xenograft animal...
The purpose of this study was to examine the associations between preoperative Liver Imaging Reporting and Data System (LI-RADS) categories prognosis after curative resection single hepatic malignancies in patients with chronic liver disease.Between January 2008 December 2010, 225 disease underwent malignant tumors (218 hepatocellular carcinomas, three cholangiocarcinomas, four biphenotypic carcinomas) undergoing gadoxetic acid-enhanced MRI. Two radiologists retrospectively categorized into...
Several clinical trials of bone marrow cell infusion in patients with liver cirrhosis (LC) have shown improvement, despite conflicting results from animal models. We investigated serial pathological features and the impact after autologous (ABMI) advanced LC. Ten LC due to chronic hepatitis B virus infection underwent ABMI. Serological tests, MRI, biopsies were performed, quality life was assessed by a questionnaire. Median serum albumin hemoglobin levels increased significantly All showed...
Purpose To compare the local-regional staging accuracy of conventional two-dimensional (2D) T2-weighted imaging protocol and three-dimensional (3D) for preoperative magnetic resonance (MR) in rectal cancer patients. Materials Methods This retrospective study was approved by institutional review board, a waiver informed consent obtained. A conducted 109 3-T MR images obtained with 2D 3D protocols Two radiologists independently assessed radiologic findings T N category lesions, conspicuity...
Abstract Background. The diagnosis of a sternal fracture is often difficult when the site shows only minimal displacement on conventional radiography. Recently, sonography (US) has been used widely in emergency room (ER). We investigated diagnostic performance US ER for fractures. Method. Thirty‐six consecutive patients examined pain and tenderness sternum after blunt chest trauma were enrolled study. Antero‐posterior lateral radiographs sonograms obtained within 24 hours admission. 2...
