Diagnostic radiology is the use of various imaging modalities to aid in the diagnosis of disease.
Methods that could be used in diagnostic radiology include among other metods:
- Conventional X-ray
- Mammography: X-ray of the breast.
- Computer Tomography (CT): X-rays taken in three dimensions and computed to make a stack of two-dimensional images.
- Single Photon Emission Computed Tomography (SPECT): The use of a gamma-emitting nuclei such as Technesium 99m to produce a three dimensional or two-dimensional array of the object or the patient.
- Positron Emission Tomography (PET): The use of a positron emitting nuclei (such as Fluor 18) to produce two distinct photons each with an energy of 511 keV. These photons are detected and used to produce a three-dimensional array representing the object or the patient.
