2. GI Contrast CT • Post-contrast CT in a patient with locally advanced gastric carcinoma. • There is diffuse thickening of the stomach wall (long arrows) and bulky left gastric and celiac adenopathy is present (short arrow).

3. AXR-Silent belly • a patient with small bowel obstruction secondary to adhesions. • The dilated small bowel loops are arranged in a ‘stepladder’ configuration.

4. Post-contrast CT • Post-contrast CT in a patient with pneumoperitoneum following perforation • of sigmoid diverticular disease. Free air is identified anterior to the liver • (long arrows) and as small pockets within the upper abdomen (small arrows).

5. Double Contrast Colon Study • double-contrast barium enema demonstrates a large sessile • polyp in the upper rectum (arrow). The surface of the polyp is irregular and, when combined with the size, malignancy is likely.

6. US of acute cholecystitis. • There is thickening of the gall bladder wall (long black arrow) and stones are seen in the gall bladder (short white arrow) with acoustic shadowing in association.

7. Magnetic resonance cholangio-pancreatography (MRCP) • MRCP image demonstrating a gallstone in the distal common • bile duct, seen as a low signal filling defect (long arrow). Note normal gall bladder • (arrowhead) and duodenal loop (small arrows).

8. Post-contrast CT of the liver in a patient with colonic carcinoma. The liver contains multiple hypodense metastases.

9. Post-contrast CT through the pancreatic body and tail in a patient with acute pancreatitis. • The pancreas is enlarged and poorly defined (large white arrow), but enhances homogeneously. Note associated inflammatory changes in the adjacent mesenteric fat (small white arrows) and normal gall bladder (black arrow).

10. Post-contrast CT in a patient with pancreatic carcinoma. • There is a large hypodense mass in the pancreatic tail (large black arrow). The splenic vein has been invaded and is not seen. Normal pancreatic head and body are indicated by small black arrows. Ascites is present (white arrow)

11. Pnacreatic ampullary carcinoma • Image from an ERCP in a patient with ampullary carcinoma. CT confirmed dilated ducts, but no obvious cause. ERCP demonstrates a dilated common bile duct (small arrow) and a should

12. Degenerative change within the right hip joint. Osteophytosis (white arrow) with geode formation (black arrow) is noted within the right hip joint with loss of joint space medially.

13. Rheumatoid Arthritis •periarticular osteopenia at the MCP joints with periarticular erosive changes in association (white arrows). Note erosive and secondary degenerative changes also present in the corpus with erosion of the ulnar styloid process.

14. GOUT • a rounded soft-tissue mass overlying the metatarsophalangeal (MTP) joint of the great toe (white arrow). There is a well-defined erosion of the head of the metatarsal of the great toe, with sclerotic overhanging margins characteristic of gouty arthropathy (black arrow).

15. Whole body isotope bone scan demonstrating multiple pathological areas of isotope uptake throughout the skeleton in keeping with disseminated skeletal metastases.

16. Multiple Myeloma • Multiple ‘punched out’ lytic lesions can be seen throughout the calvarium, which are typical of myelomatous bony involvement.

17. Osteoporosis • loss of vertebral body height and anterior wedging of several of the thoracic vertebral bodies. • osteoporotic vertebral body collapse and crush fracture. • Osteopenic bone • Dense cortical outline of the vertebral bodies
