What type of imaging is used to investigate midgut volvulus?

Midgut volvulus is a serious condition that occurs when a portion of the intestine twists around itself and the mesentery, potentially compromising blood flow and leading to necrosis. In this context, imaging is crucial for a timely diagnosis.

Plain X-ray can reveal signs of bowel obstruction, which is often associated with midgut volvulus. It may show a classic 'double bubble' sign or air-fluid levels, indicating the presence of distended loops of bowel. However, while it can suggest the diagnosis, it may not provide enough detail regarding the exact nature of the volvulus or its location.

Ultrasound is particularly useful in pediatric patients since it is non-invasive and does not involve radiation. It can help visualize the twisted bowel and any associated abnormalities. Conversely, CT scan offers a more detailed look and can precisely identify the presence and extent of midgut volvulus; however, it involves radiation exposure, which is a consideration in pediatric imaging.

Magnetic resonance imaging (MRI) is powerful in soft tissue imaging but is rarely used as a primary investigation for midgut volvulus due to factors such as availability, cost, and need for sedation in children.

Hence, while plain X-ray can indicate obstruction and lead to the investigation of midgut volv
