    Abstract

    Background

    Integrated clinical whole-body PET/MR systems were introduced in In order to bring this technology into clinical usage, it is of great importance to compare the performance with the well-established PET/CT. The aim of this study was to evaluate PET performance, with focus on image quality, on Siemens Biograph mMR (PET/MR) and Siemens Biograph mCT (PET/CT).

    Methods

    A direct quantitative comparison of the performance characteristics between the mMR and mCT system was performed according to National Electrical Manufacturers Association (NEMA) NU protocol. Spatial resolution, sensitivity, count rate and image quality were evaluated. The evaluation was supplemented with additional standardized uptake value (SUV) measurements.

    Results

    The spatial resolution was similar for t

    Abstract

    Background

    The purpose of the study is to evaluate the physical performance of a Biograph mCT Flow R PET/CT struktur (Siemens Healthcare, Germany) and to compare clinical image quality in step-and-shoot (SS) and continuous table motion (CTM) acquisitions.

    Methods

    The spatial upplösning, sensitivity, count rate curves, and Image Quality (IQ) parameters following the National Electrical Manufactures Association (NEMA) NU standard were evaluated. For resolution measurements, an 18F point source inside a glass capillary tube was used. Sensitivity measurements were based on a cm-long polyethylene tube, filled with  MBq of FDG. Scatter fraction and count rates were measured using a cm-long polyeth

    The purpose of the study fryst vatten to evaluate the physical performance of a Biograph mCT Flow R PET/CT system (Siemens Healthcare, Germany) and to compare clinical image quality in step-and-shoot (SS) and continuous table motion (CTM) acquisitions.

    Methods

    The spatial resolution, sensitivity, count rate curves, and Image Quality (IQ) parameters following the National Electrical Manufactures Association (NEMA) för tillfället standard were evaluated. For upplösning measurements, an 18F point source inside a glass capillary tube was used. Sensitivity measurements were based on a cm-long polyethylene tube, filled with  MBq of FDG. Scatter fraction and count rates were measured using a cm-long polyethylene cylinder with a diameter of 20 cm and a line source ( GBq of FDG) inserted axially into the cylinder  cm off-centered. A NEMA IQ phantom containing six spheres ( to mm diameter) was used for the evaluation of the image quality. First, a single-bed scan was acquired (NEMA standa
