MRI: T1 Discussion



- Discussion:
       - T1 images w/ short TR & w/ short TE will  provide the best anatomic detail;
       - T1 imaging is most useful for lesions involving marrow & subQ fat;
       - T1-weighted imaging also provides the highest signal-to-noise ratio and is therefore optimal for evaluating anatomic subtleties;
       - fat and lipid-containing materials as well as proteinaceous fluid will have short T1 value;
       - tissues with long T1 values include cortical bone, ligaments & tendons;
       - Muscle, tumor, & infections have intermediate-signal intensity on T1 images;
       - short TR (200) & TE (15) will emphasize T1 characteristics
