Cardiac CT (also known as "Volume Computed Tomography" or VCT) offers an innovative way for physicians to obtain the information they need to diagnose disease and life threatening illness including cardiovascular disease, stroke and chest pain.
Cardiac CT scanning is the latest innovation in computed tomography (CT) technology. VCT captures images of the heart in just five heartbeats and other organs in only a second, turning them into 3-D views that doctors can use to decide the best course of treatment.
What is VCT?
"VCT" stands for "Volume Computed Tomography." The GE's LightSpeed® VCT ushers in the next generation of CT imaging by offering game changing clinical applications in neurology, cardiology and trauma.
The LightSpeed VCT creates high-resolution anatomical images that form a three-dimensional view of a patient's anatomy breaking barriers in speed and accuracy in diagnostic capabilities. The new scanner can be used for a variety of procedures, including cancer care, stroke workup and kidney and liver exams, but the LightSpeed VCT is most beneficial for the field of cardiac imaging. This new technology can capture images of the entire heart in just five heartbeats, along with the ability to decipher between aortic dissection, pulmonary embolism and coronary artery disease, the three major causes of mortality in patients with chest pain. In addition to the new diagnostic power in cardiac cases, the LightSpeed VCT offers the speed and resolution needed for immediate imaging of blood vessels after a stroke.
GE's new LightSpeed VCT is built with a 64-channel design which increases the high-resolution volume coverage incredibly when compared to the traditional 16-slice detector. The slices produced by the VCT scanner are .5 millimeters thick, and the key to a successful diagnosis is to make the slices as thin as possible in order to achieve the highest resolution. The technology leap with VCT is huge. This is cardiology's first foray into looking at arteries in this way. The 'V' emphasizes the concept that you're looking at true volume, a 3D image with width, depth and height.
With an estimated 100 million CT scans performed annually around the world, the new LightSpeed VCT is a non-invasive procedure that benefits both patients and physicians. Fast scans help reduce patient stress and anxiety along with the time required for exams. With faster, more accurate scanning techniques, physicians are able to view clearer, sharper images, thus allowing them to review the case within five to ten minutes and make an accurate diagnosis.
