OBJECTIVE Permeability parameters from dynamic contrast-enhanced MRI (DCE-MRI) and apparent diffusion coefficient (ADC) value on diffusion-weighted imaging (DWI) can be quantitative physiologic metrics for gliomas. The transfer constant (K(trans)) has shown efficacy in grading gliomas. Volume fraction of extravascular extracellular space (ve) has been underutilized to grade gliomas. The purpose...

Magnetic resonance imaging (MRI) depicts infectious foci in the perianal region better than any other imaging modality. MRI allows definition of the fistula, associated abscess formation and its secondary extensions. Accurate information is necessary for surgical treatment and to obtain a decrease in the incidence of recurrence and complications. Radiologists should be familiar with anatomical ...

Introduction In clinical monitoring of brain tumors, Perfusion Weighted Imaging (PWI) contributes to tumor grading and to assess the response to treatment [1]. Beyond tumor perfusion, tumor hypoxia determines the response of various therapeutic approaches including radiotherapy. All these parameters may be mapped with MRI. However, the integration of several MRI maps is difficult. This wealth o...

STUDY DESIGN This is a prospective study that was undertaken at a single centre and involved 80 consecutive patients diagnosed with lumbar spinal stenosis (LSS). PURPOSE The aim of the study was to assess the efficacy of a qualitative grading system as seen on magnetic resonance imaging (MRI) as a tool in the management of multilevel LSS. OVERVIEW OF LITERATURE LSS diagnosis is clinical but...

BACKGROUND Dynamic contrast-enhanced MRI (DCE-MRI) estimates vascular permeability of brain tumors, and susceptibility-weighted imaging (SWI) may demonstrate tumor vascularity by intratumoral susceptibility signals (ITSS). This study assessed volume transfer constant (Ktrans) accuracy, the volume of extravascular extracellular space (EES) per unit volume of tissue (Ve) derived from DCE-MRI, and...

OBJECTIVES In this study, we aimed to investigate whether joint pain is derived from cartilage or bone alterations. METHODS We reviewed 23 hip joints of 21 patients with primary hip osteoarthritis (OA), which were classified into Kellgren-Laurence (KL) grading I to IV. Plain radiographs and magnetic resonance imaging (MRI) were obtained from all of the 23 joints. Two of the 21 patients had bi...

results of the 41 patients with dcm, echocardiography examination revealed 11 patients (27%) without mitral regurgitation and 12 (29%) with mild, 11 (27%) with moderate, and seven (17%) with severe mitral regurgitation. all of the morphological and functional parameters of left ventricle, atrium and mitral valve in dcm patients were greater than those in healthy subjects (all p < 0.05), except ...

STUDY DESIGN This was a single surgeon, single center-based retrospective study with prospective data collection. PURPOSE To assess the correlation between T2-weighted magnetic resonance imaging (MRI) signal intensity (SI) changes and factors such as age, duration of symptoms, baseline modified Japanese Orthopedic Association (mJOA) score and to determine its prognostic value in predicting re...

BACKGROUND To assess associations between whole-lesion apparent diffusion coefficient (ADC) metrics and pathologic findings of Likert score 3 prostate lesions at MRI/ultrasound fusion targeted biopsy. METHODS This retrospective Institutional Review Board-approved study received a waiver of consent. We identified patients receiving a highest lesion score of 3 on 3 Tesla multiparametric MRI rev...
