Radiation dose reduction through re-imaging patients with suspected artifact related abnormalities studied with a stress first SPECT/CT myocardial perfusion protocol

Description:
This study evaluates the clinical benefits of re-imaging patients who show unexpected abnormalities during stress myocardial perfusion imaging.

Clinical Relevance:
Re-imaging patients who show suspected artifacts during their initial stress images significantly decreases the need for rest imaging and its associated radiation dose. Even with hybrid CT attenuation correction systems, motion, soft-tissue attenuation, or patient-related factors may still introduce misleading defects. Repeat stress imaging provides an efficient, radiation-sparing method to confirm or refute these findings. This approach enhances diagnostic accuracy and improves clinical confidence, particularly for patients without previously documented coronary artery disease.
