Faster, better, safer: The latest in PET and SPECT

“Literally any movement of the patient or the subject is recovered as if the patient didn't move,” said Almos Elekes, global product marketing manager for GE Healthcare.

The feature reconstructs the images faster than the PET scanner acquires them, Elekes said. It’s ideal for imaging pediatric patients as well as those with neurogenerative diseases, including Parkinson’s, where very often patients present with a tremor.

Last year, GE Healthcare introduced MyoSPECT, a nuclear medicine cardiology system, which the company calls the next generation of cardiac-dedicated nuclear medicine.

The system was designed with a faster scan and workflow, providing a better patient experience and the ability to accommodate more patients, said Sonia Sahney, chief marketing officer for molecular imaging and CT at GE Healthcare.

“It really helps clinicians determine the right course of treatment for the patient, while the patient is having a much more comfortable experience,” Sahney said.

The system comes with a wider table and a wider field of view, as well as smart positioning technology to allow for optimal patient positioning. A smaller footprint allows the system to be used in a hospital or clinical setting.

Hermes Medical Solutions recently launched its Hermia molecular imaging software.

The all-in-one software platform uses artificial intelligence and automation, together with the latest computing technology, to accelerate workflow and reporting, said Rene Rebeaud, chief business officer for North America and Latin America for Hermes Medical Solutions. Some examples are AI-driven foci segmentation, AI-driven lesion tracking and automatic local registration.

Hermia also includes the Voxel Dosimetry application, which can predict and quantify, for each patient, how much radiation a tumor and surrounding cells will receive. Patients now only need to be imaged a single time for treatment follow-up, making it easier to implement in clinical practice, Rebeaud said. The application is CE marked, FDA and Health Canada cleared for a wide range of imaging isotopes.

“This is a game-changer because, historically, you had to acquire images for four or five time points to be able to perform the treatment follow-up, and now our software can achieve literally the same result with a single time point,” Rebeaud said.

The software can also perform a standardized uptake value calculation with any vendor’s SPECT camera.

“This is ideal when a department is equipped with scanners from different manufacturers, [and] staff can perform the acquisition on the camera that is best suited for the study or available when needed,” Rebeaud said. “Now, with quantitative SPECT reconstruction, you can really assess and track lesions over time with the standardized uptake value. This considerably simplifies the workflow of the department and allows for harmonized results and new assessment possibilities. “
