GE Healthcare is sponsoring a series of multicenter trials to validate the clinical efficacy of its LightSpeed VCT 64-slice CT system as a method for the diagnosis and treatment planning of cardiovascular disease, according to the Chalfont St. Giles, U.K.-based firm.
The intent of the trials is to determine what role the VCT can play in minimizing noninterventional catheterization, as well as how it can be used to improve the early diagnosis of otherwise occult coronary artery disease, the company said.
The trial will not only seek to clinically validate the use of CT for noninvasive diagnosis of coronary artery disease, but will also examine patient results and analyze changes in the cardiologist's decision-making process and patient management, GE said.
Patient enrollment began this month and the firm said that it expects results to be published next year.

![Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD). Top row: Images in a 68-year-old male patient with higher 10-year mean ambient air pollution exposure (7.9 μg/m3 for particulate matter measuring ≤2.5 μm in diameter [PM2.5] and 17.4 parts per billion [ppb] for NO2) with extensive CAD (coronary artery calcium score [CACS] >1,000 and obstructive CAD [≥70% diameter stenosis]). Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
