Phi angle gastric band radiology
WebAssessment of gastric band position is important in all studies, especially those presenting with epigastric pain. The phi angle is measured along the long axis of the band and the vertical line of the vertebral column, normally sitting between 4-58°, sitting around the gastric cardia. It is important to also assess for perforation or obstruction.
