When Should a Scan be Done to Assess Success of LU PSMA
When we give lutetium PSMA therapy or Pluvicto therapy there are 2 types of scans which are done in such patients one is the dosimetry scans now in the earlier days and even today at many centers where personalized dosimetry is not practiced the patient undergoes just one post therapy scan which kind of documents that There is lutetium PSMA uptake at all the sites of metastatic disease However the world of nuclear medicine is moving towards personalized treatments personalized dosimetry and it is important very important that each cycle of lutetium PSMA therapy be actually followed by intricate dosimetry scans which tell us not just whether we are administering enough dose to the cancer cells but also that the critical organs are being spared and we are not causing a slow damage to the critical collateral damage to the critical organs like the kidney or the liver or the bone marrow so doing a personalized dosimetry and dosimetry scans post lutetium psma therapy is slowly becoming the standard of care and it adds a lot of benefit to actually personalized dosing for lutetium PSMA therapy.
