Ultrasound (US) is also a safe, relatively inexpensive, and readily accessible imaging tool for investigation of many peritoneal diseases. However it’s of low value particularly in obtaining diagnostic images in obese and postoperative patients. Also, many peritoneal diseases have non specific US findings so, it’s used as complementary tool to CT and MR imaging.MRI can be performed with no ionizing radiation. It also offers superior soft tissue contrast to CT as well as direct multiplanar acquisition capability.
