title: Specific diagnosis of brain disease with double isotope brain scanning.
abstract: 25 patients with known cerebral disease (either CVA's or primary or secondary tumours) diagnosed by clinical and angiographic criteria were submitted to a double isotope imaging technique using 99mTcO4- and 99mTc-EHDP. The different biological behaviour of these radiopharmaceuticals has provided specific and differential diagnosis between vascular and neoplastic disease of the brain. 99mTc-EHDP is shown to be the tracer of choice for the imaging of CVA's and 99mTcO4- is confirmed as the tracer of choice for the imaging of primary or secondary tumours in the brain.
