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.

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.

Flow pulsatility in the portal venous system: a study of Doppler sonography in healthy adults.
The purpose of our study was to describe Doppler sonography patterns of venous flow in the portal system of healthy subjects and to compare pulsatility of flow with subjects' body mass, degree of inspiration, and body position. ⋯ Doppler sonography shows pulsatile portal venous flow in healthy adults, especially in thin subjects. This pulsatility has an inverse correlation to body mass. The finding of a pulsatile portal vein needs to be interpreted in clinical context and does not necessarily imply dysfunction of the right side of the heart.

A focused appendiceal CT technique to reduce the cost of caring for patients with clinically suspected appendicitis.
This investigation analyzed the potential impact on hospitalwide variable costs and total costs of introducing a focused helical CT technique for diagnosing appendicitis. ⋯ Routine use of focused appendiceal CT would lower the costs of caring for patients with clinically suspected appendicitis.
