Users of the second-generation Discovery IQ will be able to perform motion-free PET studies without the use of a respiratory gating device, which is currently required for such exams. These devices can be difficult to use, and as a result, only about 5% of PET scans employ them.
GE's MotionFree technology seamlessly integrates with existing workflows and can help to decrease patient setup time by up to 11 minutes. It also can deliver respiratory analysis in real-time. Additionally, the new model offers remote landmarking and table positioning, which can reduce total scan time by up to 10%.
About 500 Discovery IQ PET/CT scanners are currently installed in the field, according to the company, and first-generation units will have an upgrade path to the new model.
Also at SNMMI 2019, GE highlighted its Discovery MI flagship PET/CT scanner, and NM/CT 870 CZT SPECT/CT camera with 7.25-mm cadmium zinc telluride digital detectors. On NM/CT 870 CZT, GE has added the ability to scan patients with medium-energy radiopharmaceuticals, such as lutetium-177 and indium-111. Such radiopharmaceuticals are becoming increasingly common with the rise of theranostic agents that have both diagnostic and therapeutic applications.
