Abstract:
A 59-year-old woman with recent history of weakness, loss of appetite, and significant weight loss was referred for malignancy workup. On the first day, the patient underwent a 99mTc-MDP scan, which revealed diffuse pulmonary uptake in both lungs. Two days later, 99mTc-FAPI scan was performed and showed diffuse pulmonary uptake in the planar and SPECT/CT images. The study present an interesting case demonstrating FAPI-ligand uptake in metastatic pulmonary calcification.
