Diffuse pulmonary opacification in infants undergoing extracorporeal membrane oxygenation: clinical and pathologic correlation

Diffuse pulmonary opacification is commonly seen on chest radiographs from infants with severe respiratory failure treated with extracorporeal membrane oxygenation (ECMO). The chest radiographs and clinical records of 18 such infants were reviewed to determine the correlation among degree of abnormality on chest radiograph (as determined by a radiographic score), clinical severity of disease (as measured by ECMO requirements [ECMO flow rate]), and dynamic lung compliance determinations. Increasing lung compliance and decreasing ECMO flow rates correlated well with decreasing (improving) radiographic score. Pathologic changes were mainly those associated with intensive respiratory support and the underlying pulmonary condition. One patient had diffuse pulmonary hemorrhage. Other than bleeding, no distinctive pathologic features could be attributed to therapy with ECMO. We conclude that the degree of pulmonary opacification seen in infants undergoing ECMO therapy is an accurate reflection of markedly decreased lung compliance and lung volumes caused by hyaline membrane formation, pulmonary edema, and atelectasis associated with the various causes of severe respiratory failure.     

Postoperative hysterosalpingogram: radiographic-surgical correlation

The hysterosalpingograms of 46 patients who underwent previous uterine or tubal surgery were reviewed. Surgical procedures performed included cesarean section, myomectomy, uterine septal repair, tubal reimplantation and reanastomosis, and fimbrioplasty/cuff salpingostomy. The procedures and their resulting hysterosalpingographic appearances are discussed.     

Anatomy of the perirenal area

The authors comment on the use of the renal bridging septa as a sign in distinguishing compartmentalization of the perinephric space. They also address new concepts regarding the spread of pancreatic effusions and provide information on other anatomic features of the perirenal area.     

Academic uroradiology: the future

Radiologic education, research, and the practice of radiology will be of the highest quality in the future if academic departments stress organ-system subspecialization while continuing to integrate and interface with technique-based specialists. Planning should begin now to effect an orderly progression to an organ-system-based subspecialty structure for radiology training in general and for uroradiology specifically. Uroradiologists should remain as central consultants to their clinical counterparts, working collaboratively with urologists in clinical endeavors of mutual relevance. More fellowships in uroradiology should be offered that attempt to incorporate all imaging methods and procedures into the curriculum. These issues are addressed in the context of patient care, service, education, and cost containment.
