[Clinical cerebral perfusion scintigraphy with 123I-IMP]

Area of Science:

• Neuroimaging
• Nuclear Medicine
• Cerebrovascular Diseases

Background:

• Understanding the biodistribution of Iodine-123-IMP (IMP) is crucial for its application in nuclear medicine.
• Cerebral perfusion imaging plays a vital role in diagnosing and managing various neurological conditions.

Purpose of the Study:

• To review the clinical utility of single-photon emission computed tomography (SPECT) with IMP for assessing cerebral blood flow.
• To explore the indications for IMP SPECT, including ischemic cerebrovascular diseases, dementia, and epilepsy.

Main Methods:

• Review of experimental data on IMP biodistribution.
• Analysis of clinical experience with SPECT and IMP in patient populations.
• Discussion of the phenomenon of 'redistribution' of IMP in the brain.

Main Results:

• IMP SPECT is useful for evaluating patients with potential ischemic cerebral diseases like infarction, TIA, and RIND.
• The clinical significance of IMP redistribution is a key aspect of its diagnostic value.
• Dementia and epilepsy are identified as additional indications for IMP SPECT.

Conclusions:

• IMP SPECT imaging is a valuable tool for assessing cerebral perfusion, particularly in ischemic cerebrovascular diseases.
• Further methodological improvements may establish IMP SPECT as an essential diagnostic test for neuropsychiatric disorders.
