By selecting different pulses,sequences,and frequencies,the MR T1-weighted image produces images with a
A) high signal intensity (bright) water
B) high signal intensity (bright) fat, subacute hemorrhage, and contrast material
C) low signal intensity (intermediate to dark) fat
D) low signal intensity (very dark) bone and air

Question

Quizplus · Accepted Answer

On T1-weighted images,substances causing high signal intensity (i.e.,appearing bright)include fat,subacute hemorrhage,highly proteinaceous material (e.g.,mucus),slow-flowing blood,and intravenous contrast material (e.g.,gadolinium).
