The employment market for 1996 diagnostic radiology and radiation oncology graduates: training program directors' point of view.
In light of concerns about the job market, we describe the employment situation for 1996 graduates and the status and plans of training programs. ⋯ Unemployment continues to be low. "Soft" indicators such as the percentage of graduates with unsuitable positions show no deterioration. However, if major surpluses of diagnostic radiologists or radiation oncologists are pending, both the reductions in program size and the failure to fill all available slots are, to date, too minor to offer significant relief. Given the small size of actual reductions so far, the reported plans for large reductions of radiation oncologists seem questionable.

Comparative StudyQualitative hepatic venous Doppler sonography versus portal flowmetry in predicting the severity of esophageal varices in hepatitis C cirrhosis.
The purpose of this study was to compare the diagnostic accuracy of simple recognition of hepatic vein waveform abnormalities using Doppler sonography with portal Doppler flowmetry for the noninvasive assessment of esophageal varices in patients with hepatitis C cirrhosis. ⋯ Simple recognition of patterns seen in hepatic vein waveform morphology in patients with liver cirrhosis caused by hepatitis C is superior to portal Doppler flowmetry for predicting the size of esophageal varices.

High-resolution CT in the acute exacerbation of cystic fibrosis: evaluation of acute findings, reversibility of those findings, and clinical correlation.
The aims of this study were threefold: to compare high-resolution CT (HRCT) of adult patients with cystic fibrosis (CF) during acute exacerbations with asymptomatic patients with CF, to evaluate reversibility of HRCT abnormalities after exacerbations, and to correlate HRCT with clinical parameters. ⋯ Air-fluid levels in bronchiectatic cavities were the only parenchymal finding shown by HRCT that was limited to the acute exacerbation of CF in our study population. However, this finding was rare, being seen in two of 19 patients. Mucus plugging, centrilobular nodules, and peribronchial thickening were potentially reversible findings in symptomatic patients. HRCT accurately revealed disease severity in patients with CF. We also found that changes in HRCT scores correlated with clinical improvement as determined by PFTs.

High-resolution CT of the lung: determination of the usefulness of CT scans obtained with the patient prone based on plain radiographic findings.
We assessed the usefulness of chest radiographs for predicting whether high-resolution CT scans obtained with the patient prone would be valuable in assessing suspected diffuse lung disease. ⋯ In patients with suspected diffuse lung disease, obtaining high-resolution CT scans with the patient prone may be useful when chest radiographs show normal findings, possibly abnormal findings, or minimal abnormalities indicative of diffuse lung disease. However, such scans are of little value in patients whose radiographs show abnormalities indicative of diffuse lung disease.
