Mark each as TRUE or FALSE
T1-weighted images: Fat appears bright (high signal), water/fluid appears dark (low signal); best fo...
T2-weighted images: Water/fluid appears bright (high signal), making it ideal for detecting oedema, ...
STIR (Short Tau Inversion Recovery): Fat appears bright on STIR; STIR is less sensitive than T2 for ...
STIR suppresses fat signal by inverting and nulling fat, making fluid/oedema conspicuous as bright s...
