Routine renal imaging after 99mTc-glucoheptonate brain scans.

Immediately after brain scanning with 99mTc-glucoheptonate, the kidneys were imaged in 200 prospectively studied cases. Abnormalities were found in 22 cases (11%); they included renal metastases, renal cysts, and kidney displacement or obstruction by masses. In five instances, significant previously unknown abnormalities were found. The renal contours were usually better seen than on intravenous urograms or bone scans. Most kidney studies could be completed in less than 2 min, making renal imaging worthwhile as a low-cost high-yield routine addition to brain scanning.
