SNMMI: New PET tracers developed for imaging brain disorders
Top image displays a patient assessed for acute renal failure following third Lutathera administration where 3D dosimetry showed an average-per-administration kidney absorbed dose of 5 Gray, with total course of therapy being well under toxicity limits. Bottom image displays a patient’s absorbed dose to the colon after his first dose of Pluvicto where 3D dosimetry was used to confirm transient bowel obstruction leading to treatment management.
