An MRI produces detailed images without using radiation
Radiology, or diagnostic imaging, has become an essential tool for physicians to help diagnose and recommend treatment for their patients. Most of the larger diagnostic imaging centers have several types of radiology equipment for the doctor to choose from. Each piece of equipment requires extensive training and certification by the technicians operating the imaging device.
MRI (Magnetic Resonance Imaging)
MRI (Magnetic Resonance Imaging) is a loud but very important machine that uses magnetic fields and radio waves to get images of the patient. Since it does not use radiation and produces very detailed images, MRI has become the most preferred diagnostic imaging method by physicians. Most radiology centers have the tunnel/traditional types of MRI machines, but there are open MRI machines for patients who are claustrophobic.
CT/CAT Scan (Computed Tomography)
CT/CAT Scan (Computed Tomography) uses rotating X-rays and computers to obtain close and detailed images of organs, blood vessels and muscles. Providing clearer images than a normal X-ray, this type of scan is usually used for the brain, sinuses, abdomen, pelvis and chest.
Ultrasound (Sonography)
Ultrasound, or Sonography, is a diagnostic machine that uses high frequency sound waves to generate images. This diagnostic imaging machine is often used during pregnancy and to identify problems with internal organs. Ultrasound is considered the safest modality to use due to its lack of radiation, especially for expecting women.
PET/CT Scan (Positron Emission Tomography)
PET/CT, or PET Scan (Positron Emission Tomography), is a type of nuclear medicine imaging that provides three-dimensional images of the body (usually in conjunction with CT or MRI). The patient is given a small amount of radioactive material, which emits gamma rays that are then detected by the PET Scanner. This type of diagnostic imaging is often used to detect cancer, brain disorders and heart disease.
X-ray
X-ray machines use X-rays, or electromagnetic radiation, to provide images of any part of the body. Though the images are not as detailed and clear as other forms of diagnostic imaging, they are quick and often used to determine problems with dense areas of the body, such as bones or ligaments.
