What is an abdomen MRI with or without contrast?

MedlinePlus explains that an abdominal MRI, or magnetic resonance image, is a scan that uses powerful magnets and radio waves to generate an image of the inside of the abdomen and stomach area. The test can be performed using a certain dye, also called contrast, notes WebMD.

Contrast is injected intravenously during the MRI scan. While not all MRIs require contrast, WebMD explains that it can be very beneficial in certain cases to show certain anatomy more clearly. The Royal Australian and New Zealand College of Radiologists states that contrast dye improves diagnostic accuracy, especially in cases of certain tumors, blood vessels, inflammation or infection. An abdominal MRI may be used to detect cancer or diseases affecting the organs, pregnancy complications, blocked blood vessels or causes of pain or injury, according to the Radiological Society of North America.
