Diagnostic imaging techniques are essential for confirming, assessing, and documenting the course of many diseases and response to treatment. 

Here are some diagnostic imaging techniques:
Mammography: An X-ray imaging method used to examine the breast for the early detection of cancer and other breast diseases.
CT scans: A diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce images of the inside of the body.
MRI scans: A type of diagnostic imaging which uses powerful magnets and radio waves to produce detailed images of the inside of your body.
Positron emission tomography: Also called a PET/CT scan, this is a combination of the Positron Emission Tomography (P.E.T.) and Computed Tomography (CT) technologies.
Fluoroscopy: A diagnostic imaging technique that uses X-rays to make moving images of the body.
Multinuclear imaging: The mainstay when diagnosing diseases of the retina.
Optical imaging: A crucial component of medical diagnosis and treatment.
Bone scan: A diagnostic test that uses nuclear imaging. 

Topics include: Ultrasound, echocardiography, x-ray, fluoroscopy, PET, SPECT, computerized axial tomography, MRI and FMRI.
