Abdominal imaging
-
The increasing use of computed tomography in evaluating patients with acute abdominal pain has revolutionized the diagnosis of small bowel obstruction in adults. Computed tomography is incontestably the most useful and powerful tool to make positive, topographic, and etiologic diagnoses of small bowel obstruction. Good knowledge of some key signs and rigorous analysis of computed tomographic images by radiologists should lead to improved diagnosis and appropriate treatment.

This study was performed to determine the echo layer structures of the normal gastric wall and early gastric cancer when visualized with a 30-MHz ultrasonic miniprobe. ⋯ A 30-MHz ultrasonic miniprobe may provide additional imaging information of the gastric wall and could play a role in the assessment of early cancer lesions.

We studied the referrals for intravenous urography and their outcome during the year 2000 in a university department before the switch to unenhanced computed tomography (CT) and CT urography. ⋯ A switch from urography to unenhanced CT and CT urography should not be done without an audit of the referrals and their outcomes. Patients with hematuria and younger than 40 years seem more appropriate for ultrasound than for CT because the incidence of tumors and calculus disease is low. No transitional cellular cancer was found in these patients.
