abdominal MRI

10

Can be combined with endoscopy, visualize structures in hollow organs. Hampered by fat, air

abdominal ultrasonography

abdominal ultrasonography

13

Can visualize the inner wall of the upper GI tract to the duodenum. Minimally invasive

endoscopy

As well as visualizing the tissues, can: Biopsy, electro-coagulate, resect tissue, dilate, remove foreign bodies

endoscopy
