The Use of Diagnostic Ultrasound in Evaluation of the Abdomen in Primates with Emphasis on the Rhesus Monkey (Macaca Mulatta)

Abstract

To characterize the sonographic appearance of the abdominal organs in primates, a program of routine imaging and diagnostic evaluation was undertaken. Compound B-mode methodology with bistable and grey scale machines was employed utilizing a 2.25- to 3.5-MHz transducer focused at 7 cm. Visualization of the liver, gallbladder,spleen, kidney and of intraabdominal pathology are described. The stage, position, and condition of a pregnancy can be determined by this methodology.
