Single session whole body T2-weighted and T1-weighted MRI (both with and without fat suppression)
Introduction: An MRI study is commonly used for examining the local extent of a disease and often consists of acquiring images of the same region with different image contrasts. Using a moving tabletop and without re-positioning the patient, MRI has also been shown to be a feasible tool for whole body screening or staging of a disease [1-3]. In this regard, whole body MRI is potentially more ad...
متن کاملThe Use of Heavily T1-Weighted Sequences for Fat Quantification
Introduction: Separation of fat and water in MRI has been a topic of long-standing interest. The use of such techniques for quantification is of considerable clinical interest, however one of the confounding issues for accurate quantification is the different T1s of the water and fat components. As shown in several previous studies, this leads to a systematic overestimation of the fat fraction ...
متن کاملComparison of contrast-enhanced T1-weighted FLAIR with BLADE, and spin-echo T1-weighted sequences in intracranial MRI.
PURPOSE We compared periodically rotated overlapping parallel lines with enhanced reconstruction (PROPELLER, BLADE) MR technique with spin echo (SE) technique for evaluation of artifacts, and detection and delineation of brain lesions. MATERIALS AND METHODS Contrast-enhanced T1-weighted fluid attenuated inversion recovery (FLAIR) images with BLADE technique (CE T1W-FLAIR BLADE) and contrast-e...
متن کاملComparison of ultrasmall particles of iron oxide (USPIO)-enhanced T2-weighted, conventional T2-weighted, and gadolinium-enhanced T1-weighted MR images in rats with experimental autoimmune encephalomyelitis.
BACKGROUND AND PURPOSE Ultrasmall particles of iron oxide (USPIO) constitute a contrast agent that accumulates in cells from the mononuclear phagocytic system. In the CNS they may accumulate in phagocytic cells such as macrophages. The goal of this study was to compare USPIO-enhanced MR images with conventional T2-weighted images and gadolinium-enhanced T1-weighted images in a model of experime...
متن کاملcomparison of maximum signal intensity of magnevist contrast agent in modified t1 weighted spin echo, t1 weighted fast spin echo and t1 weighted gradient echo sequences
background: nowadays mri examinations have been widely used in clinical applications for many diagnoses. the use of contrast agent in mri improves lesion detection and characterization and causes more accurate diagnosis. objectives: the aim of this study was comparing to optimal dose of magnevist contrast agent in modified t1w se (spin echo), t1w fse (fast spin echo) and t1w gre (gradient ech...
