The MRI is chiefly used by doctors to test for a myriad of diseases and ailments. This procedure is a simple and non- invasive way to study the tissues, skeletal system, and organs. This study is often used to investigate tumors, spinal cord injuries, and aneurysms. It is also helpful in the detection of bone infection and a heart and blood vessel examination. The MRI machine is shaped like a giant tube, and it is made of huge magnets. During your time in the tube, all jewelry that may attract the magnet needs to be taken off. On the other hand, a CT scan assists in examining the bone structure and anatomy of organs, the diagnosis of bone tumors, internal bleeding, and blood clots. CT scan utilizes a combination of x-rays and computers to display pictures of your organs, bones, and other tissues. CT scan is also less expensive than an MRI.
