Cerebral Scintigraphy (SPECT)
Tumoral Masses : Visualization of a lesion on brain scintigraphy depends on the localization, dimensions and perfusion of the lesion as well as the presence of absence of blood brain barrier disruption.
Trauma : Subdural hematoma is a very established indication for braind scintigraphy. In acute subdural hematoma, sensitivity is around 50% , however this reaches to 100% in sub-acute or chronic lesions. The epidural hematoma, on the other hand, cannot be displayed with scintigraphy.
Inflammatory Diseases : While HMPAO is non-specific, the abscess and tumoral masses can be differentiated from each other with leukocyte tagging method.
Occlusive Cerebrovascular Diseases
Arteriovenous Malformations : The diagnosis can be achieved by cerebral scintigraphy in 95% of AVM.
Epilepsy : The epileptic focus can be determined with the perfusion defects revealed during ictal, inter-ictal and post-ictal periods.
Dementia and Psychiatric Anomalies : Typical perfusion defects occur in Alzheimer and schizophrenia.
Movement Anomalies :Parkinson and Huntington diseases
Brain Death: is the most sensitive method.
