Abdomen Imaging Guidelines

Covers condition-specific abdominal and pelvic imaging (CT, MRI, ultrasound, nuclear studies, CTA/MRA, enterography/enteroclysis, HIDA, gastric emptying, etc.) with modality- and indication-specific guidance and surveillance intervals, while excluding or deeming investigational certain uses (routine 3D/4D post‑processing, most CEUS except when CT/MRI cannot be performed, PET for sclerosing mesenteritis) and restricting gadolinium use in pregnancy. Key requirements: a documented clinical evaluation within 60 days (telephone/email acceptable), required pre‑imaging labs/prior testing for endocrine/renal/hepatobiliary indications, stored ultrasound images, adherence to contrast/ modality selection rules (e.g., CT with/without contrast based on renal function/allergy, MRI without/with contrast coding, MR enterography preferred in young IBD), and Medical Director review for exceptions such as life‑saving CT in pregnancy.

"A current clinical evaluation (within 60 days) is required before advanced imaging can be considered."
