Comparison 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...
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 کاملProton Density MRI Increases Detection of Cervical Spinal Cord Multiple Sclerosis Lesions Compared with T2-Weighted Fast Spin-Echo.
BACKGROUND AND PURPOSE There is a paucity of literature that supports the Consortium of Multiple Sclerosis Centers guideline that proton density MR imaging is a core spinal cord sequence. We hypothesized that proton density fast spin-echo imaging is superior to T2 fast spin-echo MR imaging for the detection of cervical cord MS lesions. This study compared the detection rate and conspicuity of c...
متن کاملAdvantages of Fast Recovery Variant for T2-Weighted Fast Spin-Echo Imaging of the Brain
Purpose Fast recovery fast spin-echo (FRFSE) is a new pulse sequence using a driven equilibrium pulse to convert residual transverse magnetization into longitudinal magnetization and has demonstrated improvements in T2-weighted imaging for the spine (1) and the temporal bone (2) predominately related to improvements in fluid contrast. Its possible value for brain imaging has not been tested and...
متن کاملcomparison of maximum signal intensity of contrast agent on t1-weighted images using spin echo, fast spin echo and inversion recovery sequences
conclusion using standard imaging parameters, each mri sequence reaches its maximum si in a specific contrast concentration, which is highest in se and least in ir in a comparison between se, fse and ir sequences. results this study shows that maximum si will appear at different ranges in different sequences. the maximum si can be seen at concentrations of 5.95, 4.96 and 3.98mmol/l for se, fse ...
