What imaging study would you order for cholecystitis?
Ultrasound, confirm with nuclear hepatobiliary study (HIDA scan)
What imaging study would you order for an intestinal obstruction?
Abdominal x-ray, confirm with CT with contrast
What imaging study would you order for appendicitis?
CT with contrast or appendiceal CT with rectal contrast or US
What imaging study would you order for nephrolithiasis?
CT without contrast (test of choice) or abdominal x-ray or intravenous pyelogram (IVP)
What imaging study would you order for an ovarian pathology?
Ultrasound
What imaging study would you order for diverticulitis?
CT with contrast, NO endoscopy or barium enema acutely

Ultrasound or CT
What imaging study would you order for hematuria (persistent)?
CT with contrast, confirm with cytoscopy or CT with contrast
What imaging study would you order for fibroid uterus?
Ultrasound, confirm with MRI
What imaging study would you order for a pelvic mass (female)?
Ultrasound, confirm with CT with contrast or laparoscopy
What imaging study would you order for bone metastases?
Bone scan, plain x-rays for multiple myeloma
What imaging study would you order for pregnancy evaluation?
Ultrasound (transvaginal detects sooner than transabdominal), first get beta-HCG
What imaging study would you order for a fracture?
X-ray, CT scan without contrast can help evaluate complex fractures
What imaging study would you order for osteomyelitis?
X-ray, confirm with bone scan and/or MRI with contrast
What imaging study would you order for arthritis?
X-ray, confirm with MRI
What imaging study would you order for pyloric stenosis?
Ultrasound, upper GI series is second choice
What imaging study would you order for Meckel diverticulum?
Meckel scan (nuclear medicine)
With suspected GI perforation, why do you not want to use barium?
It can cause a chemical peritonitis, use water-soluble contrast (e.g. gastrografin)
