68Ga-PSMA

Assessing the Under-Estimation of Nodal Tumor Burden by using 68GA PSMA and 11C-Choline PET/CT Scan

The technology, PET/CT exemplifies one of the most sensitive of the diagnostic modalities we have to assess the spread of recurrent prostate cancer. 

However, there is an assumption that even PET/CT, despite its sensitivity, still under-estimates the actual tumor burden. There is an additional hypothesis that the under estimation of tumor burden increases progressively by the number of positive nodes that are visualized by preoperative imaging.
