SSFSE MR Imaging of Focal Hepatic Lesions
With improvements in pulse sequence design and gradient amplifiers complete breath-hold MR imaging of the liver is possible enabling rapid evaluation, which is relatively free of motion artifacts. The combination of Single Shot Fast Spin-Echo (SSFSE) and Fast Multiplanar Spoiled Gradient-Echo(FMSPGR) sequences provide both breath-hold T2and TI-weighted non-contrast images, as well as multiphase...
متن کاملDetection of focal hepatic lesions with MR imaging: prospective comparison of T2-weighted fast spin-echo with and without fat suppression, T2-weighted breath-hold fast spin-echo, and gadolinium chelate-enhanced 3D gradient-recalled imaging.
OBJECTIVE The purpose of this study was to compare breath-hold three-dimensional (3D) rapid gradient-echo (GRE) MR imaging obtained before and after gadolinium chelate injection with T2-weighted fast spin-echo and T2-weighted breath-hold fast spin-echo (BHFSE) MR imaging in the detection of focal hepatic masses. SUBJECTS AND METHODS Fifty-three patients with 108 focal hepatic masses had, pros...
متن کاملMagnetic Resonance Imaging of Pulmonary Embolism: Diagnostic accuracy of contrast-enhanced 3D MRA, contrast- enhanced low flip angle 3D gradient echo and noncontrast steady-state free precession sequences
Introduction: Acute pulmonary thromboembolic disease is a significant cause of morbidity and mortality, with estimated yearly incidence of 650,000 cases in the USA. Pulmonary computed tomography angiography (CTA) is the current gold standard for PE diagnosis. However CTA has limitations regarding the use of iodinated contrast and relatively high ionizing radiation burdens, a consideration given...
متن کاملSegmentation of Carotid Plaque using Multi-Contrast 3D Gradient Echo MR Imaging
Introduction: The ability to identify plaque components in atherosclerotic carotid arteries using MRI is well established [1] and is amenable to automatic segmentation with techniques such as Morphology-Enhanced Probabilistic Plaque Segmentation (MEPPS) [2]. Measurements of components, such as necrotic core (NC), calcification (CA) and loose matrix (LM) have enabled researchers to identify plaq...
متن کاملIntra- and paraorbital lesions: value of fat-suppression MR imaging with paramagnetic contrast enhancement.
The orbital area of 18 individuals was examined by using a combination of fat-suppression contrast-enhanced MR imaging to determine whether contrast between fat and surrounding tissues could be improved over that obtained with conventional fat-suppression techniques alone. We used a hybrid technique combining two independent methods of fat suppression. Subjects consisted of 16 patients and two ...
