PET maximum intensity projections with a constant linear gray scale show multiple liver metastases and subdiaphragmal peritoneal deposits. Tumor and renal uptake persist over time while organs such as spleen, lungs and liver, along with the urinary excretion, are progressively washed out. The highest tumor contrast was found at 1 h post injection, while 4h images suffer from poor count statistics. There is remarkably low accumulation of 68Ga-OPS202 in sst2-positive organs such as pituitary, spleen, adrenals and uncinate process of the pancreas.
