1.	CAT scan is essentially _________(a) a finer X-ray of bones(b) a detailed x-ray(c) x-ray of soft tissues(d) x-ray of brainThe question was asked in semester exam.Question is from Computerized Axial Tomography in chapter Diagnostic Investigation via Imaging Techniques of Clinical Science
Answer» Correct OPTION is (C) x-ray of soft tissues Explanation: The X – rays pass through the body completely. The bones are ABLE to provide resistance to them to a limit by absorbing them. This resistance causes the image to appear. However, for soft tissues, the single shot of X- Rays cannot give an image as they do not pose any obstruction to them. To image soft tissues, multiple X – Rays of high energy need to be passed. Since it can NEGATE out the effect of the BONE and image in slices, CT is good for imaging soft tissues.
