The hepatocyte-specific contrast agent gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) was developed to improve the detection and characterization of focal liver lesions at magnetic resonance (MR) imaging. Approximately 50% injected dose is taken up into functional hepatocyte excreted via biliary system. Because this property, Gd-EOB-DTPA has potential be a agent. When combined with T2-weighted MR cholangiography, Gd-EOB-DTPA–enhanced imaging can allow morphologic...
Purpose: To prospectively evaluate the diagnostic performance of double-echo gradient-echo (GRE) chemical shift magnetic resonance (MR) imaging in differentiation angiomyolipoma (AML) with minimal fat from other renal neoplasms, pathologic examination or follow-up data serving as reference standard. Materials and Methods: Institutional review board approval informed consent were obtained. Double-echo GRE MR was performed 55 patients (29 men 26 women; mean age, 49 years ± 14 [standard...
AIM:To evaluate the ultrasonography (EUS) features of gastric gastrointestinal stromal tumors (GISTs) as compared with leiomyomas and then to determine EUS that could predict malignant GISTs. METHODS:We evaluated endoscopic in 53 patients mesenchymal confirmed by histopathologic diagnosis.The GISTs were classified into benign groups according histological risk classification. RESULTS:Immunohistochemical analyses demon strated 7 46 GISTs.Inhomogenicity, hyperechogenic spots, a marginal halo...
Objectives: To assess the elasticity values in breast tissues using magnetic resonance elastography (MRE) and examine association between of invasive cancer with prognostic factors pathologic response to neoadjuvant systemic therapy (NST). Methods: A total 57 patients (mean age, 54.1 years) cancers larger than 2 cm diameter on ultrasound were prospectively enrolled. The (mean, minimum, maximum) cancers, normal fibroglandular tissues, fat measured via MRE a commercially available acoustic...
The purpose of our study was to evaluate the MRI features portal biliopathy.MR cholangiography coupled with dynamic 3D gradient-echo imaging could not only detect vein occlusion, cavernous transformation, and gallbladder varices but is also suitable for delineating associated bile duct abnormalities.
Although the vast majority of gastrointestinal (GI) masses are epithelial neoplasms, a variety subepithelial infrequently encountered during endoscopic or radiologic examination. A mass, which was previously called submucosal is defined as mass covered with normal-appearing mucosa, whether underlying process intramural extramural in origin. At contrast material–enhanced computed tomography (CT), hypervascular usually detected more easily than isoattenuating hypovascular masses. Entities that...
Background Higher peak enhancement and washout component values measured on preoperative breast MRI scans with computer-aided diagnosis (CAD) are presumed to be associated worse recurrence-free survival. Purpose To investigate whether CAD-extracted kinetic features of cancer the heterogeneity these at distant metastasis-free survival in women invasive cancer. Materials Methods Consecutive newly diagnosed who underwent were retrospectively evaluated between 2011 2012. A commercially available...
Background The Vesical Imaging–Reporting and Data System (VI‐RADS) is a newly developed system of bladder cancer staging with multiparametric MRI (mpMRI), which can be used to predict the presence muscle invasion for cancer. Purpose To evaluate accuracy three mpMRI series (T 2 WI, diffusion‐weighted imaging [DWI], dynamic contrast‐enhanced image [DCEI]) VI‐RADS diagnosing invasive (MIBC). Study Type Retrospective. Population In all, 66 pathologically proven cancers in 32 patients. Field...
OBJECTIVE. The purpose of this study was to evaluate and compare the diagnostic performance image quality low-dose CT performed with adaptive statistical iterative reconstruction (ASIR)-V those routine-dose filtered back projection (FBP) in evaluation abdominal organ injury. MATERIALS AND METHODS. enrolled 197 patients trauma who underwent multiphase CT, including portal venous phase imaging FBP delayed 50% ASIR-V. presence injuries (liver, spleen, pancreas, kidney) reviewed, were graded...
