Pregnant patient pelvic imaging protocol

Indications

This protocol is used to evaluate adnexal masses and fibroids in pregnant patients. It can also be used to evaluate nonspecific pelvic pain during pregnancy and appendicitis.

Preparation

• IV contrast agent: None

• Oral contrast agent: None

• Have the patient void prior to the start of the study

• Cover from iliac crests through symphysis pubis. If pathology extends above or below these levels, increase coverage

• All T2 single-shot fast-spin echo sequences can be run without breath-hold to continuously cover the pelvis and pathology as one series.

Exam sequences

1. (1) Coronal T2 single-shot fast-spin echo (large field of view to cover at least ½ kidneys) – Assess presence and location of kidneys. Evaluate for hydronephrosis. Identify T2-bright and T2-dark lesions.

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

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

4. (4) Axial T1 in- and out-of-phase BH – Identify T1-bright lesions and microscopic fat.

5. (5) Axial volume-interpolated gradient echo BH – Characterize T1-bright signal in lesions. Identify blood products.
