Outcomes of Stereotactic Radiation Therapy (SRT) for Primary and Metastatic Liver Tumors with 3-D CT and Single Photon Emission Computed Tomography (3D-CT/SPECT) Treatment Planning

Abstract

SPECT provides functional imaging of the liver parenchyma through the uptake of radioactive colloid by Kupffer cells in proportion to vascular perfusion. We report on outcomes and toxicity of liver SRT/SBRT based on 3D-CT/SPECT treatment planning with conformal avoidance of well-perfused functional normal liver volumes (FNLV).
