Lung perfusion scintigraphy is a cornerstone for evaluating pulmonary embolism but may reveal unexpected vascular anomalies. Persistent left superior vena cava, a congenital anomaly, can cause a right-to-left shunt when draining into the left atrium, bypassing pulmonary circulation. We report the incidental detection of persistent left superior vena cava during lung perfusion scintigraphy in a patient with post-COVID-19 hypoxia. Dual-site radiotracer injections and SPECT/CT confirmed the diagnosis, highlighting the need for adaptive imaging techniques to accurately interpret atypical findings in nuclear medicine.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
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...
Radiological Investigation II: MRI and Ventilation Perfusion Scan
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...
