MotionFree

How often are you working around motion instead of seeing through it?

Respiratory motion negatively affects about half of all PET/CT procedures. And not just in the thorax, but all the way down to the pelvis as well. What’s more, it affects your images in ways that you can’t always predict or read around. It can hide small lesions, make staging for treatment difficult and lead to inaccurate SUV and volume measurements. Every situation is unique. However, current solutions are cumbersome and take too long to set up, which puts you in the difficult position of having to pick and choose which situations to use it in. As a result, only a small percentage of overall procedures affected by motion receive the benefits of motion correction.

Images & Clinical Experience

Clear the way for clear images

  • SMALL LESION DETECTABILITY

    Activity at scan time = 1.6 mCi / 59.2 MBq. Discovery MI 25 AFOV scanner at low activity utilizing the deviceless MotionFree acquisition of 20 overall minutes. This case demonstrates a combination of low-dose PET & MotionFree respiratory scanning as a routine workflow. Comparison to static images reveals improvement in volumetric accuracy of lesion size.

  • SMALL LESION DETECTABILITY

    Discovery MI 25 AFOV scanner utilizing the deviceless MotionFree acquisition of 20 overall minutes. The MotionFree respiratory correction software improves quantitation and image quality in the small liver lesions.

  • IMPROVED LESION CONSPICUITY WITH ⁶⁸Ga-DOTATATE

    Discovery MI 25 AFOV scanner utilizing the deviceless MotionFree acquisition of 20 overall minutes. Improved lesion conspicuity with ⁶⁸Ga-Dotatate at low doses.

  • IMPROVED LESION DETECTABILITY WITH ⁶⁸Ga-DOTATATE

    Another dotatate exam, with relatively high BMI. Lesion detectability is better, as new lesions are seen with MotionFree when compared to conventional static image. Shape of the liver is sharper and better defined, as well.

  • IMPROVED LESION DETECTABILITY AND FLEXIBLE WORKFLOW

    In this case, MotionFree detected significant respiratory motion from only a single bed. This saves time in comparison to a scan that utilized an external respiratory-correction device. Size and activity of lesions are enhanced with MotionFree respiratory motion correction, and different scan times using MotionFree provided comparable image quality, with both showing improved lesion detectability in the liver area compared to conventional technology.

  • NO ADDITIONAL TIME WITHOUT COMPROMISE

    Beds 2-4 selected for motion screening. Only beds 3 & 4 triggered for respiratory motion correction. Retrospectively processed with Th=0 to additionally apply MotionFree to bed 2.
