Male pelvis protocol: scrotum

Indications

This protocol is used for generalized screening of pelvic pathology, i.e. pain, metastatic disease, masses. It can also be adapted for evaluation of scrotal and penile pathology (see below).

• IV contrast agent: 1 mmol/kg gadopentetate dimeglumine at 2 cc/s

• Oral contrast agent: None

• At least 24-gauge IV; connect to power injector

• Have patient void just prior to start of the exam

Exam sequences

1. (1) Coronal T2 single-shot fast-spin echo BH – Identify T2-bright and T2-dark lesions.

2. (2) Sagittal T2 fast-spin echo – Identify T2-bright and T2-dark lesions.

3. (3) Axial T2 fast-spin echo – Identify T2-bright and T2-dark lesions.

4. (4) Coronal T2 fast-spin echo FS – Identify T2-bright and T2-dark lesions. Evaluate for pelvic fluid and T2-bright osseous lesions.

5. (5) Axial volume-interpolated gradient echo BH – If using surface coil for scrotal imaging, perform this sequence with larger field of view pelvic phased-array coil to image the pelvis from the iliac crests through the symphysis pubis.

6. (6) Axial volume-interpolated gradient echo BH pre-contrast.

7. (7) Axial volume-interpolated gradient echo BH post IV administration of contrast at 70 seconds.

8. (8) Sagittal volume-interpolated gradient echo BH post IV administration of contrast at ~2 min.

9. (9) Coronal volume-interpolated gradient echo BH post IV administration of contrast at ~3 min.
