Abstract |
Technetium 99mTc pertechnetate brain scanning were
performed in 3 cases of head injury (2 chronic subdural
hematomas and 1 acute epidural hematoma), 2 cases of
brain abscess and 1 case of intracerebral hematoma
associated with arteriovenous anomaly. In all the cases
brain scintigrams showed "hot areas." Literatures on
radioisotope scanning of intracranial lesions were
briefly reviewed. With the improvement of radioisotope
scanner and development of new radiopharmaceuticals
brain scanning became a safe and useful screening test
for diagnosis of intracranial lesions. Brain scanning
can be easily performed even to a moribund patient
without any discomfort and risk to the patient which
are associated with cerebral angiography or
pneumoencephalography. Brain scanning has been useful
in diagnosis of brain tumor, brain abscess, subdural
hematoma, and cerebral vascular diseases. In 80 to 90%
of brain tumors positive scintigrams can be expected.
Early studies were done with 203Hg-Neohydrin or 131I-
serum albumin. With these agents, however, patients
receive rather much radiation to the whole body and
kidneys. In 1965 Harper introduced 99mTc to reduce
radiation dose to the patientand improve statistical
variation in isotope scanning.
