"Gastric and colonic endoscopy, ultrasound and small bowel barium examinations are the first-line studies for all non-specific clinical GI symptoms."
"Enterography (and enteroclysis) with CT and especially MRI have become important in the investigation of GI disorders. These techniques are superior to enteroclysis in the evaluation of eccentric tumours and secondary lesions (peritoneal carcinomatosis)."
"may cause severe GI bleeding"
"most common GIT malignancy 3"
"MRI: non-specific intermediate SI on T1 and T2"
"US: similar to other bowel tumours, hypoechoic, loss of gut signature, obstruction 3"
"T1: isointense to bowel wall"
"T2: iso- to hypointense"
"CT: dystrophic calcifications can be seen (better with CT than MRI)"
"enteroclysis: infiltrative tumour with irregular and segmental luminal narrowing"
"MRI: non-specific intermediate SI on T1 and T2"
"MRI: low on T1, slightly increased on T2, hypovascular and thus very little contrast enhancement"
"hypervascular NETs are typically demonstrated in the arterial phase"
"typically shows asymmetrical but circumferential wall thickening with associated luminal dilatation (intestinal aneurysm), due to tumour extension into muscularis propria and destruction of autonomic nerve plexus"
