T1-weighted sequence
WebT1-weighted black blood images allow anatomic evaluation including clear depiction of the pericardium. T2-weighted black blood sequences can be performed with or without fat saturation to highlight areas of edema, which can be seen in various clinical entities including acute ischemia, myocarditis, and sarcoidosis [ 5, 6 ]. WebAug 3, 2024 · MR imaging plays a significant role in detection and characterization of different brain diseases. The role of the post-contrast T1-weighted image magnetic resonance imaging (T1W MRI) sequence has been widely established in previous studies and clinical practice. In this study, we aim to share our experience as regards the added …

WebMar 12, 2024 · T1 W EIGHTED. T1-weighted (T1W) sequences depend on longitudinal relaxation and can be obtained as spin echo or fast spin-echo. These require breath holding in end inspiration or end expiration. Images can also be obtained with ECG gating with late diastolic acquisition to reduce cardiac motion artifacts. Protein-rich contents, fat, melanin ... WebThe most common MRI sequences used include T1-weighted (T1w) and T2-weighted (T2w) scans(5). T1w sequences display those structures mainly made with fat. Thus, they reveal gray matter as gray, white matter as white, bones as black, and cerebrospinal fluid as black. Meanwhile, T2w sequences highlight structures containing more water.
