Overview
Magnetic resonance imaging (MRI) has become the common technique for diagnosing appendicitis in children and pregnant patients.
Appendicitis MRI
- MRI usage has become common in the diagnosis of appendicitis for children and pregnant patients.[1]
- The high dosage of radiation can be harmful for children and developing fetus, while posing a nearly negligible risk in healthy adults.
- The enlarged uterus displaces the appendix during the second and third trimesters of pregnancy, making it difficult to find by ultrasound. An MRI is therefore preferred.[1]
- On an MRI, a periappendiceal stranding appears as an increased fluid signal on the T2 weighted sequence (while it is reflected by fat stranding on a CT scan).[1]

Axial T2-Weighted MRI demonstrates a dilated fluid filled appendix with periappendiceal fat stranding and two appendicoliths (dark signal within the appendix lumen).[2]
