Abstract:
82Rb is frequently used in PET myocardial perfusion imaging to detect ischemia. We present the case of a 64-year-old man referred for PET myocardial perfusion imaging to rule out ischemia. On PET images, an abnormal focus of uptake was present in the subcutaneous soft tissue overlying the right chest, which corresponded to a soft-tissue nodule on CT. This lesion was biopsied and proved to be a mammary fibromyoblastoma, an extremely rare and benign lesion. This case is presented to emphasize the importance of reviewing extracardiac structures on PET/CT myocardial perfusion studies.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
