The non–surgical tests involve the procedure that does not penetrate the body. These are of different types.
- A magnetic resonance imaging(MRI) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. MRI can look at the brain for tumors, an aneurysm, bleeding in the brain, nerve injury, and other problems, such as damage caused by a stroke.MRI of the chest can look at the heart, the valves, and coronary blood vessels. sing MRI to look at blood vessels and the flow of blood through them is called magnetic resonance angiography(MRA). MRI can check for problems of the bones and joints, such as arthritis, problems with the temporomandibular joint, bone marrow problems, bone tumors, cartilage problems, torn ligaments or tendons, or infection. MRI can check the discs and nerves of the spine for conditions such as spinal stenosis, disc bulges, and spinal tumors.
