[Single-photon emission-computed tomography of the head using labelled amines in visualizing the cerebral...

Area of Science:

• Neurology
• Radiology
• Medical Imaging

Background:

• Cerebral hemodynamics and microcirculation are crucial in neurological pathologies.
• Accurate assessment of cerebral perfusion is vital for diagnosis and treatment planning.
• Existing methods may have limitations in providing comprehensive microcirculatory data.

Purpose of the Study:

• To investigate cerebral hemodynamics in patients with neurological conditions.
• To evaluate the utility of a specific radiopharmaceutical and imaging technique for assessing cerebral microcirculation.
• To provide clinicians with rich information on cerebral microcirculation for various pathologies.

Main Methods:

• Clinical material from patients with suspected tumors, vascular diseases, and craniocerebral traumas was analyzed.
• Cerebral microcirculation was investigated using a multidetector single-photon emission tomograph "Testoscan" (USSR).
• Intravenous administration of 99mTc-hexamethylpropilene-amyloxine was employed for imaging.

Main Results:

• The radiopharmaceutical 99mTc-hexamethylpropilene-amyloxine proved effective for evaluating cerebral perfusion.
• The "Testoscan" tomograph provided rich information on cerebral microcirculation.
• The study demonstrated the applicability of this method in patients with diverse neurological conditions.

Conclusions:

• The described method using 99mTc-hexamethylpropilene-amyloxine and single-photon emission tomography is valuable for assessing cerebral microcirculation.
• This technique offers significant clinical information for managing patients with neurological pathologies.
• Further research can explore the broader applications of this imaging approach in neurology.
