Oct 4, 2018 · The use of imaging studies has grown faster than any other medical service. 36 With the increasing volume of CT scans, there is an increasing population radiation burden. Today it is a well-known fact that exposure to ionizing radiation from CT and nuclear medicine results in an increased malignancy risk. 37

Magnetic resonance imaging (MRI) is a medical imaging technique that uses a magnetic field and computer-generated radio waves to create detailed images of the organs and tissues in your body. Most MRI machines are large, tube-shaped magnets. When you lie inside an MRImachine, the magnetic field inside works with radio waves and hydrogen atoms in yo...
MRIis a noninvasive way for a medical professional to examine your organs, tissues and skeletal system. It produces high-resolution images of the inside of the body that help diagnose a variety of conditions.
Because MRI uses powerful magnets, the presence of metal in your body can be a safety hazard if attracted to the magnet. Even if not attracted to the magnet, metal objects can distort the MRI images. Before having an MRIexam, you'll likely complete a questionnaire that includes whether you have metal or electronic devices in your body. Unless the d...
Before an MRIexam, eat as you would normally and continue to take your usual medicines, unless you're told otherwise. You will typically be asked to change into a gown and to remove things that might affect the magnetic imaging, such as: 1. Jewelry. 2. Hairpins. 3. Eyeglasses. 4. Watches. 5. Wigs. 6. Dentures. 7. Hearing aids. 8. Underwire bras. 9....
During the test
The MRImachine looks like a long narrow tube that is open on both ends. You lie down on a movable table that slides into the opening of the tube. A technologist monitors you from another room. You can talk with the technologist by microphone. If you have a fear of enclosed spaces, called claustrophobia, you might receive a drug to help you feel sleepy and less anxious. Most people get through the exam without difficulty. The MRImachine creates a strong magnetic field around you, and radio wav...
After the test
If you haven't been sedated, you can resume your usual activities immediately after the scan.
A doctor specially trained to interpret MRIscans, called a radiologist, will look over the images from your scan and report the findings to your doctor. Your doctor will discuss important findings and next steps with you.

May 22, 2024 · PET scans are commonly used to detect cancer metastases anywhere in the body. Single photon emission computed tomography (SPECT): This type of imaging test uses a radioactive substance and a special camera to create 3D images. Bone scan: With a bone scan, a radioactive tracer is injected which is taken up by bones.
Optical Coherence Tomography (OCT) is a non-invasive imaging technique that provides high-resolution, cross-sectional images of biological tissues. Widely used in ophthalmology, it aids in diagnosing and monitoring eye diseases by revealing detailed retinal structures. OCT Imaging.

007451. Medical imagingis the technique and process of imagingthe interior of a body for clinical analysis and medical intervention, as well as visual representation of the function of some organs or tissues (physiology). Medical imaging seeks to reveal internal structures hidden by the skin and bones, as well as to diagnose and treat disease.
