comparison 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 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 ...

Y. Han, J. Hwang, J-Y. Chung, H. Park Department of Electrical Engineering, Korea Advanced Institute of Science and Technology, Daejeon, Korea, Republic of Introduction Diffusion tensor imaging (DTI) can provide valuable information regarding brain connectivity and neurological diseases. However, acquiring DTI is not an easy process because it has to be acquired in a short period of time with h...
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 کاملMR T1-weighted inversion recovery imaging in detecting brain metastases: could it replace T1-weighted spin-echo imaging?
BACKGROUND AND PURPOSE T1-weighted inversion recovery (T1IR) imaging demonstrates higher brain tissue contrast and is more sensitive to contrast enhancement than T1-weighted spin-echo (T1SE) imaging. However, the effectiveness of the 2 imaging sequences in detecting brain metastases has not been studied. The objective of this report was to determine which sequence should be used for detecting b...
