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.
