Yttrium-90 based bremsstrahlung Imaging with a solid state detector gamma camera: A first imaging experience with GE-NM CT 850

Abstract

INTRODUCTION Yttrium-90 (Y90) is an efficient therapeutic radioisotope for tumour treatment due to its high-energy beta rays. However, due to the vast energy spectra of Y-90, its always been challenging for Y-90 Bremsstrahlung imaging with traditional Phtomultipliar tube-based Anger gamma cameras. In the last few years, the solid-state gamma camera with a Caediumium Zinc Telluride (CZT) crystal has changed the imaging experience due to its direct conversions of signals and high signal-to-noise ratio, which produces high spatial and contrast resolution in the images compared to the traditional Anger PMT-based gamma camera. This presentation explained our site’s experience of post-Y90 Bremstrulung imaging, probably the first globally with the general electronics (GE)© NM CT870 model.
