Interpreting myocardial perfusion scintigraphy using single-photon emission computed tomography. Part 1

Area of Science:

• Nuclear Cardiology
• Cardiovascular Imaging
• Medical Imaging Techniques

Background:

• Myocardial perfusion scintigraphy is a key diagnostic tool.
• Single-photon emission computed tomography (SPECT) is widely used for this purpose.
• Coronary artery imaging, particularly multislice computed tomography (angio-CT), is becoming more prevalent.

Purpose of the Study:

• To outline the protocol for myocardial perfusion scintigraphy with SPECT.
• To discuss SPECT indications in light of emerging angio-CT findings.
• To provide guidance on interpreting SPECT results and related metrics.

Main Methods:

• Detailed protocol description for myocardial perfusion scintigraphy using SPECT.
• Review of current indications for SPECT, considering angio-CT data.
• Explanation of result interpretation, including the 17-segment polar map and total perfusion deficit.

Main Results:

• Established protocol for SPECT myocardial perfusion scintigraphy.
• Guidelines for integrating SPECT with angio-CT findings.
• Standardized approach to interpreting left ventricle myocardial perfusion using the 17-segment polar map and total perfusion deficit.

Conclusions:

• SPECT remains a valuable technique for assessing myocardial perfusion.
• The protocol and interpretation methods discussed aid in clinical decision-making.
• Understanding total perfusion deficit is crucial for accurate diagnosis.
