Role of imaging
Endoscopy is the mainstay for investigation of GERD. Radiology does not have a part to play in the standard assessment of GERD.
CT is not helpful in the diagnosis of GERD although it may be used in the assessment of patients with chest and abdominal pain. A normal CT does not exclude all pathology.
