Question

Short Tau inversion recovery sequences are typically used for the evaluation of

A) T1 Relaxation
B) Fluid Suppression
C) T2 Relaxation
D) Fat Saturation

Answer 1

Short Tau Inversion Recovery (STIR) sequences are used in MRI primarily for Fluid Suppression, helping to distinguish between normal and abnormal fluid-filled tissues by suppressing fat signals.

Step-by-step explanation:

Short Tau Inversion Recovery (STIR) sequences are a specialized type of magnetic resonance imaging (MRI) technique. The primary purpose of STIR is to suppress the signal from fat in the image, making it especially useful for detecting lesions or abnormalities in tissues where fat is normally present. Therefore, the correct answer is B) Fluid Suppression.

This is because STIR sequences are excellent for highlighting differences between normal and abnormal fluid-filled tissues, which often appear brighter on T2 scans. By suppressing the fat signal, these sequences can enhance the visibility of edematous tissues and other pathologies.
