CT lung screening will be performed on a multi-slice CT. Its unprecedented speed means it can produce precise images for more accurate diagnoses of injury and illness, in a significantly shorter amount of time.

Multi-slice CT is the fastest type of CT available today. It enables clinicians to perform standard CT exams in a fraction of the time, which means your exam will be finished sooner. As important, it provides much clearer images with even more anatomical detail than traditional CT scans, which will aid your doctor in making a more accurate diagnosis. The speed of multi-slice also means that fast-moving organs like the heart and lungs can be imaged with CT for the first time.
