Ultrasonography in Cholestatic Jaundice

Abstract

To the Editor: The diagnostic problems of the patient with cholestatic jaundice have been raised in two recent case reports from the Massachusetts General Hospital (November 10, 1977, and February 23, 1978, issues of the Journal). These comments refer in particular to the more recent example. We agree with Dr. Ferrucci that the false-negative rate for dilatation of the bile ducts is relatively small for both ultrasound and computed tomography. In fact, the most recent comparative figures availiable indicate an accuracy of 88 per cent for computed tomography¹ and 96.5 per cent for ultrasound.² Thus, we agree with Dr. . . .
