Abstract:
A 75-year-old woman with papillary thyroid carcinoma who underwent 131 I radioiodine treatment was incidentally found to have an established left cerebral infarct demonstrating 131 I uptake on posttherapy whole-body scan. False-positive iodine accumulation can occur in benign processes and other malignancies, necessitating awareness among nuclear medicine physicians to avoid misdiagnosing metastatic disease. SPECT/CT can be utilized to enhance diagnostic accuracy when needed.

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...
