In the Current Era, doctors mainly use diagnostic imaging techniques to narrow down possible causes of pain or illness for a more accurate diagnosis. There are different types of diagnostic imaging, including X-rays, CT scans, and MRI. the sort of imaging used depends on the part of the body the doctor wants to ascertain on a picture, also because the sort of imaging that's readily available to the patient.
So what's the main difference between X-rays, CT scans and MRI?
X-Rays
X-rays are the foremost common and widely available diagnostic imaging technique. albeit a patient may have a more sophisticated test, they're going to often receive an X-ray first.
X-rays use radiation to supply images of the body. When the rays undergo the body, dense objects—such as bones—appear white on the film. X-rays are typically wont to view and diagnose bone disease, degeneration, fractures, dislocations, infections and tumors.
Though often wont to examine skeletal structures, an X-ray also can be wont to check out other internal structures, like organs. during this case, the patient may given barium sulphate or dye to form the organs stand out more clearly within the X-ray image.
During an X-ray, the a part of the body that's being checked out are going to be placed between an X-ray machine and film . The machine then sends electromagnetic waves (radiation) through the body, reflecting the patient’s internal structures on the exposed film.
Although the quantity of radiation used for an X-ray isn't considered dangerous, doctors will take certain precautions if the patient is pregnant.

CT Scans
A computerized tomography scan, or CT scan, is analogous to an MRI therein it produces detailed, high-quality images of the body. The CT scan may be a more sophisticated and powerful X-ray that takes a 360-degree image of internal organs, the spine and vertebrae. Contrast dyes are often injected into the blood to form structures within the body more visible on the CT scan.
A CT scan produces detailed images of organs, bones, soft tissue and blood vessels and may be wont to more easily diagnose cancer, heart condition , appendicitis, musculoskeletal disorders, trauma and infectious diseases.
A CT scanner seems like an outsized box with a tunnel within the center. The patient lies on a table that slides in and out of the tunnel, while the scanner rotates round the patient, producing cross-section images of the body. The technologist performing the scan sits during a separate room with computers on which the pictures are displayed. The technologist can speak with the patient using speakers and microphones.
A CT scan is costlier than an X-ray and isn't always available at small or rural hospitals.

MRI
Magnetic resonance imaging, or MRI, uses a strong magnet and radio waves to make detailed, high-resolution cross-section images of bones and soft structures inside the body. MRI doesn't include radiation, as X-rays and CT scans do, and is usually wont to diagnose bone and joint problems also as torn ligaments and cartilage and herniated discs.
During an MRI scan, the patient lies still on a table that slides into the tube-shaped MRI scanner. The machine then creates a magnetic flux round the patient and pulses radio waves into the world of the body being pictured. The radio waves cause the tissues within the body to resonate. These vibrations are translated into detailed 2D images captured by a special computer virus .
Like an X-ray or CT scan, the MRI is painless, but the machine does produce a bang . Because the MRI uses large magnets, make certain to notify your doctor if you've got metal clips, implants or other metal objects within the body.
MRI scans aren't available in the least hospitals. If your doctor has ordered an MRI, you'll got to attend a delegated imaging center for your scan.
