Buck, Mario Löhr, Camelia-Maria MonoranuIn all 3 patients, there is a marked overlap between 68Ga-DOTATATE uptake and MR contrast agent enhancement. Radiotracer accumulation is most pronounced in areas with intense contrast enhancement. Shown are axial views of contrast-enhanced T1-weighted MR as well as fused MR/PET images.
