Study Notes
Medical Imaging Techniques
- X-rays are used for imaging in radiography, which involves exposure to ionizing radiation.
Magnetic Resonance Imaging (MRI)
- MRI has good resolution, allows for 3D reconstruction, and uses gadolinium contrast, which is relatively non-toxic except for pregnant women.
Fluoroscopy
- Barium sulfate is commonly used as a contrast medium in fluoroscopy procedures.
Computed Tomography (CT) Scans
- The primary imaging modality used in CT scans is X-rays.
CT Scan Technology
- CT scans involve the use of a rotating gantry with multiple detectors to produce slice-like images.
Imaging Modalities
- Magnetic Resonance Imaging (MRI) is an imaging technique that does not typically require the use of ionizing radiation.
Fluoroscopy Imaging
- Fluoroscopy involves real-time imaging by continuous X-ray beams to visualize moving structures within the body.
Nuclear Medicine
- The main difference between Single Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) imaging techniques is the type of radioactive material used.
- SPECT and PET scans differ from traditional X-rays or CT scans in that they use radioactive materials to produce images of the body's internal functions.
Radioisotopes in Nuclear Medicine
- Radioisotopes such as uranium and thorium are mentioned in the context of nuclear medicine as they can be used to produce radioactive materials for diagnostic imaging.
