Figure 1. Patient presenting with abdominal pain, initially suspected to have a partially obstructing lesion of the proximal ascending colon as evidenced by the abdominal radiograph (a). CT revealed extensive inflammation due to diverticulitis of the sigmoid colon (b).
Figure 3. (a) Axial CT image showing a 6 mm area of calcification in the region of the head of the pancreas. (b) Coronal oblique reconstructed image clearly shows the intraductal position of the calcification.
Figure 4. (a) Axial contrast-enhanced CT image showing a possible abnormality of the right renal artery. (b) Maximum intensity projection image showing a small right kidney and renal artery stenosis.
Figure 5. (a) Axial contrast-enhanced image suggests splenic artery aneurysm. (b) Curved planar reformation image shows it to be a tortuous splenic vein, and the artery is normal.
Figure 6. (a) Contrast-enhanced images showing thickening of the small bowel wall, poor perfusion of the right kidney and a filling defect in the superior mesenteric artery (SMA). (b) Coronal images show a segment of thrombus occluding the SMA.
Figure 7. (a) Common bile duct (CBD) stone misinterpreted as gastrografin in a small bowel loop on the axial image. (b) Coronal multiplanar reformation clearly shows the stone in the CBD.
Figure 9. (a) Axial image showing thickened gall bladder and duodenal wall that superficially resembles tumour. (b) Coronal image clearly shows a gallstone in the proximal duodenum.
