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 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...
متن کاملFast Spin Echo Imaging
In conventional spin echo (SE) imaging, the longitudinal magnetization (that is generated by the presence of the main magnetic field, B0) is tipped into the transverse plane using a radiofrequency (RF) pulse that tips the magnetization 90 degrees. Once in the transverse plane, the magnetization rotates, or precesses, around the axis of the main magnetic field. As the transverse magnetization pr...
متن کاملComparison of Fast Recovery Fast Spin Echo and Conventional Fast Spin Echo for T2 Weighted Imaging of the Prostate Gland
Introduction The FRFSE sequence is a modification to the standard FSE sequence in which additional RF pulses are used to accelerate recovery of longitudinal magnetization after the echo train is acquired. The sequence can provide enhanced fluid signal in the setting of short TR for joint imaging. We compared this sequence to standard FSE using a long TR for axial endorectal coil T2 weighted ima...
