A CT Scan is typically done on our spine, heart, head, chest, abdomen, abdomen and knee. During a CT Scan, the body is made to pass through a tunnel-like machine that rotates through a 360-degree arc as it takes X-Ray images in rapid succession. These images are subsequently fed into a computer to produce an ‘all-around’ 2D snapshot of any part of the body. A minimally invasive and painless procedure, a CT Scan can be done on any part of the body in little time. While essentially 2D in nature (ie, producing two-dimensional image slices), a CT Scan can also be employed to create 3D images. A CT Scan cost depends on the body parts which you want to scan.
