Brain Scan with SPECT/CT

Brain Scan with SPECT/CT

At SJMC, our advanced SPECT/CT brain scan offers unparalleled insights into brain health and how it functions. SPECT imaging, also known as Single Photon Emission Computed Tomography, is a cutting-edge method for generating detailed images of the brain’s internal structure and function. This method creates tomographic images of the three-dimensional distribution of a radiopharmaceutical. This technique can be used to measure regional cerebral perfusion.

The radiotracer used (ECD or HMPAO) enters the brain cells due to their lipophilic nature and remains there due to conversion into hydrophilic compounds.

The scan estimates relative regional flow differences based on the comparison of count density ratios between various regions (e.g. right/left asymmetries, ratio in relation to reference regions, etc.).


What are the indications for a Brain scan with SPECT/CT?

• Acute stroke: Perfusion SPECT provides valuable information in acute stroke with respect to complications, outcome, or treatment decisions.
• Chronic ischaemia: In chronic cerebrovascular disease assessment of functional reserve capacity may guide decisions regarding vascular surgery.
• Evaluation of cerebrovascular disease.
• Evaluation of suspected brain inflammation.
• Evaluation of suspected dementia. Early detection and differential diagnosis of various forms of dementia such as Alzheimer’s disease, Lewy body dementia, Parkinson’s disease with dementia, vascular dementia, and frontotemporal dementia.
• Preoperative evaluation for potential ischaemia following carotid artery sacrifice.
• Presurgical lateralisation and localisation of epileptogenic foci
