Overview
Magnetic resonance imaging (MRI) has become the common technique for diagnosing appendicitis in children and pregnant patients.
MRI
MRI usage has become investigation of choice in the diagnosis of appendicular abscess for children and pregnant patients because of [1]
- Low risk of radiation in children and developing fetus.
- 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.
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]
