Awareness of the potential for transmission of the spread of viral diseases through homologous blood products has led to an increasing awareness of techniques that minimize these risks. Reinfusion of postoperatively shed blood has become popular, but its efficacy has been questioned. In an effort to determine the viability of postoperatively collected cells, 10 consecutive patients undergoing an identical surgical procedure were studied; their blood was tagged with chromium 51 and reinfused. Reinfused cells were then monitored serially at determined intervals and expressed as a percentage of postinfusion activity. At 4 days, 75.9% of initial activity remained. These figures are comparable to those previously reported for intraoperative and preoperative cell collection. Blood salvaged postoperatively is not significantly damaged and is as viable as blood collected from other autologous and homologous sources.

Several methods are presently available for measuring the mineral content of bone. Those in widespread use include dual-photon absorptiometry and quantitative CT. The feasibility of using dual-energy digital chest radiography for determination of the mineral content of posterior ribs on digital chest images was studied by using a prototype unit. The results showed a significant difference in the mineral density of the posterior ribs of control subjects and those of patients who had osteoporosis (251.1 +/- 36 mg Ca2+/cm2 of rib vs 158.8 +/- 48 mg Ca2+/cm2, p less than or equal to .01) and a close correlation with values obtained by dual-photon absorptiometry of the lumbar spine (r = .77). The results suggest that this technique can provide an accurate assessment of the presence or absence of osteoporosis.

The radiographic findings in 24 cases of bronchiolitis obliterans with organizing pneumonia and 16 cases of usual interstitial pneumonia were reviewed and compared. Some cases of bronchiolitis obliterans with organizing pneumonia have been mistaken for usual interstitial pneumonia, although the two diseases have distinct pathologic findings. Clinically, the diseases often have different manifestations. Bronchiolitis obliterans with organizing pneumonia has a better prognosis and often responds well to steroids. This study shows that the radiologic findings of bronchiolitis obliterans include alveolar opacities without lung-volume loss. Patients with usual interstitial pneumonia, however, have bilateral diffuse interstitial opacities with occasional honeycomb changes, and there is loss of lung volume in most patients. These findings suggest that the chest radiograph can aid in distinguishing the two diseases.
