Breast uptake on a myocardial perfusion scan

A 42-year-old female underwent a myocardial perfusion scan (MPS) for the evaluation of coronary artery disease. Raw and cine loop images hinted at abnormal tracer accumulation in the chest. Review of short-axis slices and low-dose computed tomography images taken for attenuation correction and their subsequent fusion confirmed the presence of focal tracer uptake localized to nodular breast masses. This case demonstrates that despite MPS not being optimized to detect breast pathologies, careful inspection of unprocessed images and the application of available software for fusion can help detect concurrent pathology.
