Repeatability of tumor blood flow quantification with 82Rubidium PET/CT in prostate cancer — a test-retest study

摘要

BackgroundNon-invasive tumor blood flow (TBF) quantification is a candidate approach for risk stratification and monitoring of prostate cancer patients. Validation data have recently been published on prostate TBF measurement with the widely used positron emission tomography (PET) flow tracer ⁸²Rubidium (⁸²Rb). However, no test-retest data is available for TBF measurement with ⁸²Rb PET in prostate cancer. Such information is important to determine the potential clinical usefulness of the technique. The aim of the present study was to determine the test-retest repeatability of TBF measurement with both dynamic and static ⁸²Rb PET.
