Suspected Appendicitis

Symptom

suspected appendicitis

Considerations

• study choice depends on age and clinical suspicion. In children <14, ultrasound probably first choice for high and very low clinical suspicion for appy. Equivocal US likely will require CT however. MRI or US for pregnant women.
• In adults, CT probably best first choice. IV contrast preferred, but oral contrast not usually necessary unless very thin patient.

Recommended tests

• CT abdomen and pelvis with IV contrast
• CT abdomen and pelvis without IV or oral contrast
• US right lower quadrant
• MRI abdomen and pelvis with and without IV gadolinium

For other considerations, call or text the radiologist.
