Optimization of inversion time for postmortem short-tau inversion recovery (STIR) MR imaging.
PURPOSE Signal intensity and image contrast differ between postmortem magnetic resonance (PMMR) images and images acquired from the living body. We sought to achieve sufficient fat suppression with short-tau inversion recovery (STIR) PMMR imaging by optimizing inversion time (TI). MATERIAL AND METHODS We subjected 37 deceased adult patients to PMMR imaging at 1.5 tesla 8 to 60 hours after con...
متن کاملCardiovascular magnetic resonance of myocardial edema using a short inversion time inversion recovery (STIR) black-blood technique: Diagnostic accuracy of visual and semi-quantitative assessment
BACKGROUND The short inversion time inversion recovery (STIR) black-blood technique has been used to visualize myocardial edema, and thus to differentiate acute from chronic myocardial lesions. However, some cardiovascular magnetic resonance (CMR) groups have reported variable image quality, and hence the diagnostic value of STIR in routine clinical practice has been put into question. The aim ...
متن کاملMR evaluation of vertebral metastases: T1-weighted, short-inversion-time inversion recovery, fast spin-echo, and inversion-recovery fast spin-echo sequences.
PURPOSE To compare the detectability of vertebral metastatic disease on T1-weighted, short-inversion-time inversion recovery (STIR), fast spin-echo (FSE), fat-saturated FSE, and inversion recovery FSE (IRFSE) MR sequences using percent contrast and contrast-to-noise ratios. METHODS Patients with proved metastatic disease underwent imaging on a 1.5-T MR system with sagittal T1-weighted (800/20...

متن کاملImaging spinal osteomyelitis and epidural abscess with short TI inversion recovery (STIR).
MR imaging, primarily the spin-echo technique, is increasingly important in evaluating spinal disease [1-3]. We have found, however, that short TI inversion recovery (STIR) in conjunction with spin-echo techniques provides higher tissue contrast images in shorter imaging times while minimizing imaging degradation due to motion and pulsation. The STIR sequence suppresses the signal from fat [4],...
