Discovery NM/CT 670 CZT was engineered to deliver improvements in lesion detection[iv], image quality and patient comfort and combined with advanced quantitative applications provided through Xeleris 4.0, it can help clinicians better diagnose and monitor diseases earlier. The new SPECT/CT is the world’s first general purpose SPECT/CT imaging system with a new digital detector powered by cadmium zinc telluride (CZT) technology. This enables direct conversion of photons into a digital signal that eliminates the signal loss and noise inherent in conventional SPECT/CT detection technology, therefore making the technology more efficient. Until now, CZT technology has been limited to organ-dedicated devices, whereas Discovery NM/CT 670 CZT is the first to allow doctors to perform exams on every organ, including whole-body exams.

This system is intended to help improve the clinicians’ confidence and patient experience. The combined capabilities will allow clinicians to detect smaller lesions[iv] and quantify them more accurately[iii] due to the increased spatial and contrast resolution. This may have a significant role in assessing and monitoring responses to therapies. Having the ability to complete multiple scans in a single visit and reduce the injected dose or the scan time by 50 percent[vi] will improve patient experience. Optimizing the duration of the exams or the injected dose represents not only an improvement for the patient experience, but also could provide economic and clinical benefits.


Researchers have identified clinical scenarios where the combination of multiple SPECT tracers could aid physicians in diagnosing and giving much better and more specific reports in difficult patient conditions. However, performing such multi-isotope exams is quite challenging on conventional cameras. Multiple isotope exams could offer a greater insight into the diagnosis and monitoring responses to treatments. With GE’s new Discovery NM/CT 670 CZT, clinicians will be able to simultaneously visualize and analyse multiple physiological processes in a patient, gaining insights into multiple dimensions of the patient’s anatomy and physiology at the same time.

The Discovery NM/CT 670 CZT is powered by the new Xeleris 4.0 workstation. In the past, Xeleris led the way with mobilized applications that gave you accessible, easy-to-use tools to enhance productivity. Now, Xeleris 4.0 is leading the way with modern, quantitative applications for nuclear medicine. For example, Q.Brain can accurately diagnose neurodegenerative diseases, Q.Lung enables the diagnosis of pulmonary embolism by identifying V/Q mismatch, Q.Lung can also confidently classify patients eligible for lung resection surgeries, and Q.Metrix can quantify tracer uptake across any lesion or organ.
