AB Computer-generated curves from 99mTc DTPA renal studies provide information about renal blood flow and function. The characteristic appearance of these curves can be altered by a variety of pathologic and/or artifactual conditions. One such alteration can be the appearance of a “double peak” in any portion of the curve. Three such occurrences are presented. In each case, with careful review of the dynamic computer images and discussion with the technologist, a plausible explanation of the curve aberration could be determined. The appearance of a second peak in the renal curves requires careful review of the computer-acquired images for visualizing entry of additional tracer into the venous circulation.
