[Perfusion brain imaging with SPECT-technique. German Guideline S1]

Area of Science:

• Neurology
• Radiology
• Nuclear Medicine

Background:

• The Association of the Scientific Medical Societies in Germany (AWMF) developed a guideline for brain perfusion imaging.
• Current clinical practice requires standardized protocols for accurate diagnostic interpretation.

Purpose of the Study:

• To provide practical guidance on the indication, examination, and interpretation of brain perfusion SPECT.
• To reflect the current state-of-the-art in brain perfusion imaging techniques.

Main Methods:

• Guideline development based on current scientific knowledge and clinical expertise.
• Detailed description of patient preparation, tracer handling, and quality control.
• Technical aspects of image acquisition using gamma cameras and image processing.

Main Results:

• Comprehensive information on the indication and procedural aspects of brain perfusion SPECT.
• Guidance on radiation dosimetry and technical performance for image acquisition.
• Advice on interpreting SPECT findings and identifying potential pitfalls.

Conclusions:

• The guideline serves as a practical tool for clinicians performing and interpreting brain perfusion SPECT.
• Standardized protocols ensure consistent and reliable diagnostic outcomes.
• Adherence to the guideline aids in optimizing patient care and diagnostic accuracy.
