Gamma camera images were obtained in 12 patients whose radiographs showed large, typical bone islands. Four patients had focal increased activity corresponding to the radiographic site of the lesion. Biopsy in these 4 patients, done by en bloc resection in 2, confirmed or was consistent with the diagnosis of a bone island. This brings to 5 the number of histologically documented bone islands with positive radionuclide images known to the authors. However, these cases were carefully selected, and positive images of bone islands are rare using current techniques. Scintigraphic visualization is presumably dependent on a combination of factors, including size, growth rate, location, and the sensitivity of the radiopharmaceutical and imaging device.

Back pain and the radiologist.

The exact role of the radiologist in assessing patients with low back pain remains vague, which is in keeping with this syndrome's uncertain etiology and controversial therapy. Conventional radiographs of the lumbosacral spine have a limited role in most such patients, primarily in excluding neoplasm, infection, or ankylosing spondylitis. This examination can ordinarily be limited to two views; and, for radiation and economic reasons, radiographs should usually be initially deferred in young patients and/or those with acute symptoms. Symptoms will abate in most of these patients, making radiological examination unnecessary. Computed tomography (CT) is the method of choice in the diagnosis of spinal stenosis and possibly herniated nucleus pulposus and facet joint abnormalities as well. Preliminary data showing symptomatic relief of pain following facet joint injection could open an entire new area of interventional radiology. Confirmatory studies are needed in this exciting and potentially important area of investigation.
