Abstract

Decreased absolute tumor blood flow (TBF) measured by arterial spin labeling perfusion imaging (ASL-PI) on 3-tesla magnetic resonance imaging demonstrated the reduced size and growth hormone (GH) secretion of a large GH-producing pituitary adenoma in a 32-year-old man in response to octreotide therapy. The study shows the usefulness of ASL-PI in providing a biomarker of the antiangiogenic effect of octreotide.
