A Comparative Analysis of the Accuracy of the Technetium-99m Pertechnetate Brain Scan: Followup of 1000 Patients

Winston-Salem, North Carolina

ABSTRACT

A review of 1000 patients scanned with ^99mTc pertechnetate for intracranial lesions produced 148 positive scans. In the series 72 out of 95 patients with proven intracranial neoplasms (81.5%) had positive scans. The distribution of these positive scans with respect to the various types of neoplasms was presented, as well as comparative analysis with ¹⁹⁷Hg and ²⁰³Hg chlormerodrin brain scanning. Positive scans were obtained in a number of non-neoplastic conditions. A comparison of the accuracy of the brain scan was made to other diagnostic tests: the echoencephalogram, the electroencephalogram, skull films, the arteriogram, and the pneumoencephalogram-ventriculogram.
