Relative density measurements in a simple lung phantom by Compton backscatter.

Compton backscatter of 60 keV gamma radiation from a simple lung phantom has been used to measure changes in "lung" density. It was shown how introduction of a small volume of air can increase as well as decrease the count. Radiation scattered from the "chest wall" was prevented from entering the detector by careful choice of geometry. The remaining count increased linearly with "lung" density. The relative increase of count rate with density was entirely independent of "chest wall" thickness. With our apparatus a change of 0.01 kg/L in "lung" density produced a change in count rate of 2.2%.

Femoral intraarterial digital angiography: an outpatient procedure.

Selective intraarterial digital angiography was performed in 50 patients with known or suspected peripheral vascular disease. Excellent anatomic detail was provided by low-volume injection of 80 mgl/ml contrast medium. The procedure was performed with a 20- to 21-gauge needle or short 3 French catheter as an outpatient procedure. No complications were observed. Thirty-five patients underwent subsequent surgical repair of abnormalities demonstrated by this direct intraarterial technique.

Giant air cyst of the sigmoid complicating diverticulitis: report of a case.

A giant gas cyst of the sigmoid is reported, and the relevant medical literature is discussed. The vast majority of these lesions are pseudocysts and are a complication of diverticulitis that has not been emphasized in previous reports. The diagnosis should be able to be established by various roentgenographic procedures.
