Centrilobular emphysema (CLE) is a disease defined pathologically. Assessment of the accuracy of high resolution computed tomography (CT) in the diagnosis of centrilobular emphysema has been hampered by a lack of pathologic correlation. We applied high resolution computed tomography to 20 postmortem lung specimens fixed by a method that allows for direct(More)
Invasive pulmonary aspergillosis in the immunocompromised host is difficult to diagnose. Early therapy with amphotericin B improves survival. We correlated early pathologic findings with high-resolution CT of a fixed-inflated air-dried lung obtained from an autopsied patient with invasive pulmonary aspergillosis. Two distinct types of lesions were found(More)
Pulmonary infections and lung rejection are the two major complications of lung transplantation. Although the therapies for these two processes differ greatly, they often cannot be differentiated using standard radiography. We applied high resolution CT (HRCT) to seven lung specimens that were obtained from patients who had received a heart-lung transplant.(More)
Radiographic identification of pulmonary metastases has proved to be a challenging problem. We applied high resolution CT (HRCT) to 180 post-mortem lung specimens prepared by a method that allows for direct one-to-one pathologic-radiologic correlation. Of the 180 lungs, 32 had pulmonary metastases. The location, number, size, and interstitial changes were(More)
Computed tomography (CT) can establish the diagnosis of lipoid pneumonia in lung masses by detecting fat. In this case report, the diagnosis of lipoid pneumonia was first suggested by CT, supported by a long history of mineral oil ingestion, and confirmed by needle aspiration biopsy of the larger of two lung lesions and specific stains. In the future, the(More)
Automated medical communication systems for patient care usually enhance timeliness and retrievability. The effect of automated systems on communication quality has not been sufficiently measured. The radiology reports produced with the automated radiology reporting system at the Johns Hopkins Hospital were evalueate for quality and compared to reports(More)
