A recent study published in EJNMMI Research looked at the clinical impact of OncoFreeze AI, Siemens Healthineers' deviceless AI-enabled motion management feature, showing that the standard uptake volume and metabolic volume is more accurate using the feature, which could impact metabolic tumor volume assessment.

Spectrum Dynamics
In 2022, Spectrum Dynamics released the latest version of D-SPECT cardiac scanner software, providing current and new users with additional features and capabilities, such as TruCorr and TruPlanar.

D-SPECT TruCorr is a software application that generates attenuation-corrected myocardial perfusion images without requiring additional scanning sessions for the patient. The emission-based attenuation correction, based on deep learning using the patient's own myocardial perfusion SPECT data, is commercially available, with users in the U.S., Europe, and Asia. The technology averts the need for the patient to incur radiation exposure from an additional CTAC transmission scan or to endure longer or multiple appointments, said Jim Haisler, vice president of Global Commercial Operations at Spectrum Dynamics.

“We get improved image quality, efficiency, and accuracy,” Haisler said. “I would, in a way, call it a kind of revolution. This has never been released in a commercial forum before. It's been more in research than on the commercial [side].”

The company's VERITON-CT digital SPECT/CT features the same detector technology introduced with the D-SPECT, which allows for dynamic imaging. VERITON-CT's temporal resolution and sensitivity allow TruFlow imaging: one scanning session captures the dynamic flow plus the functional and anatomical information in SPECT and CT tomographic fashion. This is clinically relevant in many nuclear medicine routine applications such as three-phase bone scans, renal scans and, more recently, myocardial flow reserve (MFR) quantitation using SPECT/CT.

The scanner's new capabilities include a workflow feature that allows personalization of the SPECT scan based on the patient's body contour, as defined by the CT. The system will recommend parameters to optimize scan time and image quality when performing a total body SPECT/CT scan. Within seconds of scan completion, the final result is an attenuation-corrected total body scan ready for review and quantitative analysis.

United Imaging
United Imaging has added new features to its uMI 550 PET/CT scanners. Among those is uCare.iQC, an automated quality control program that helps with workflow, providing time and dose savings.
