The use of gadopentetate dimeglumine for contrast enhancement in magnetic resonance imaging (MRI) offers several benefits in the evaluation of brain disorders. Perhaps the greatest benefit of contrast enhancements is in the assessment of patients with metastatic brain disease. Leptomeningeal spread of ...

By increasing the contrast of an image, it will be easy for analysing because of detailed information. This increase in contrast can be done by number of ways in image processing. This paper compares different methods of enhancement of brain MRI using histogram based techniques. 展开 ...
Contrast material enhancement for cross-sectional imaging has been used since the mid 1970s for computed tomography and the mid 1980s for magnetic resonance imaging. Knowledge of the patterns and mechanisms of contrast enhancement facil...
Our purpose was to compare prospectively the sensitivity of contrast-enhanced magnetisation transfer (MT) MRI and gradient-echo (GE) T1-weighted images in metastatic disease of the brain. We studied 52 patients with brain metastases, using conventional T1-weighted GE and MT spin-echo (SE) images...
While a contrast MRI provides the doctor with valuable information, they typically won’t order an MRI with contrast unless they think it’s necessary. For instance, in most cases, work-related injuries, sports injuries and back pain don’t usually call for intravenous contrast exams. Schedule ...
Purpose: We wished to assess the merits and weaknesses of postcontrast fat-suppression (FS) brain MR imaging in children for the evaluation of various enhancing lesions as compared with postcontrast conventional T1- weighted or magnetization transfer (MT) imaging. Materials and Methods: We reviewed...

INTRODUCTION: The aim of this study is to investigate perfusion characteristics of brain arteriovenous malformation (AVM) by means of MRI perfusion-weighted imaging (PWI). METHODS: Forty-three patients with brain AVM were prospectively included and investigated by PWI-MRI. Diagnosis of type of diseas...
