A systematic review and meta-analysis on the radiation dose of computed tomography in hybrid nuclear medicine imaging.

ABSTRACT:

Background

While diagnostic reference levels (DRLs) are well-established for the radiopharmaceutical part, published DRLs for the CT component of positron emission tomography/computed tomography (PET/CT) and single photon emission computed tomography/computed tomography (SPECT/CT) are limited. This systematic review and meta-analysis provides an overview of the different objectives of CT in hybrid imaging and summarizes reported CT dose values for the most common PET/CT and SPECT/CT examinations. Also, an overview of already proposed national DRLs is given.

Methods

A systematic literature search was performed to identify original articles reporting CT dose index volume (CTDI_vol), dose-length product (DLP) and/or national DRLs for the most frequently performed PET/
