Study Notes
Radiology Modalities in Gastrointestinal Radiology
- X-ray: used mainly for suspected bowel obstruction, poor soft tissue resolution
- Barium studies: can show the inside lumen of the bowel, used mainly for swallowing disorders
- Ultrasound: first line in biliary pathology, good for liver, spleen, and ascites, first line in children with acute abdomen, can diagnose and monitor small bowel disease
- CT: used extensively in the abdomen, can show normal anatomy, appendicitis, diverticular disease, liver cirrhosis with ascites, splenomegaly, and gallstones
- MRI: specifically used for Magnetic Resonance Cholangiopancreatogram (MRCP) to look for gallstones in the CBD if ultrasound can't see them
- Nuclear medicine: no specific details mentioned
Barium Studies
- Fluoroscopy: X-ray video
- Normal anatomy on Barium studies: no specific details mentioned
Conditions and Pathologies
- Achalasia: no specific details mentioned
- Hiatus hernia: no specific details mentioned
- Barium enema: used to look for polyps and inflammation of the colon, largely redundant now, replaced by CT colonography
- Small bowel obstruction vs Large bowel obstruction: no specific details mentioned
- Appendicitis: can be diagnosed using CT
- Diverticular disease: can be diagnosed using CT
- Liver cirrhosis with ascites: can be diagnosed using CT
- Splenomegaly: can be diagnosed using CT
- Gallstones: only 10% are calcified, ultrasound is better for diagnosis
