A Practical Approach to Optimize Scan Protocol for Simultaneous Whole-Body Positron Emission Tomography/Magnetic Resonance Imaging in Cancer Staging.

ABSTRACT:

Objective

The aim of the report is to present time efficient whole-body positron emission tomography/magnetic resonance imaging (PET/MRI) protocol evolved and tested for comprehensive evaluation of cancer patients.

Materials and methods

Whole body as well as regional simultaneous PET and MRI was performed on Biograph mMR (Siemens, Erlangen, Germany) Simultaneous PET/MRI system in 4500 clinical cases of various cancers from 2013 to 2017 with an in-house designed imaging protocol to assess its utility.

Results

Using this protocol, the whole body is covered with optimized sequences (T1, T2, short tau inversion recovery, diffusion, and 3D volumetric interpolated breath-held) with PET which has been found adequate for complete metastatic workup in 30-45 min. With region-sp
