Where in the algorithmic approach for the work up of small bowel obstruction does abdominal radiography lie? Abdominal radiography is the preferred initial radiologic examination for patients with suspected small bowel obstruction, primarily because of its widespread availability and low cost. However, it is only diagnostic in 50% to 60% of cases so if clinical …
Key radiographic finding of bowel obstruction The hallmark of obstruction, whether mechanical or functional, is dilatation of bowel. The rule of “3s” defines abnormal dilation of the intestine: Small bowel 3 cm or larger Transverse colon 6 cm or larger Cecum 9 cm or larger Differentiating bowel obstruction from paralytic ileus may be challenging, but …

Optimum radiographic evaluation for pneumoperitoneum Ideally, a frontal radiograph of the lower chest and upper abdomen with the patient in the upright position should be obtained to identify free air under the diaphragm. If there is an equivocal finding for pneumoperitoneum, then lateral decubitus views can be performed, as this is the most sensitive plain radiographic technique …
When requesting an imaging examination what information should a clinician provide for a radiologist? By communicating the following information, a clinician helps ensure that an imaging examination will be conducted and interpreted optimally for each patient. Provide pertinent or significant medical history and clinical information related to the examination: (a) key findings from history, physical …
What adrenal lesions should NOT be biopsied? Because of the risk of hypertensive crisis, possible pheochromocytomas in any of the above situations should not be needled. Pheochromocytomas do not have specific imaging features and thus must be suspected clinically with confirmation testing for urine or serum catecholamines.
When is adrenal gland biopsy indicated? In patients with no history of malignancy, most incidentally discovered adrenal masses less than 4 cm in diameter are benign and should be evaluated with CT scans or MRI. For adrenal masses greater than 4 cm and not typical for adenoma, myelolipoma, hemorrhage, or simple cysts, surgical resection should …
