10. A 62-year-old man comes to the physician for a follow-up examination. He has a 6-month history of increasingly severe, dull back pain and a 14-kg (30-lb) weight loss despite a normal appetite. Recent x-ray films of the thoracolumbar spine showed no abnormalities. He has no history of trauma or serious illness. He takes no medications. He is 173 cm (5 ft 8 in) tall and weighs 91 kg (200 lb); BMI is 30 kg/m2. Examination shows no other abnormalities. Test of the stool for occult blood is negative. A complete blood count, serum electrolyte levels, and urinalysis are within the reference range. Which of the following is the most appropriate next step in diagnosis?
A ) Measurement of serum CA 19-9 level
B ) Measurement of serum carcinoembryonic antigen (CEA) level
C ) CT scan of the abdomen
D ) Laparoscopy
E ) Upper endoscopy
F ) Mesenteric angiography

i think it is ct scan. because it can detect and exclude many casuses of back pain in this patient. according to the result i can progress in to more specific tests.
