Abstract:
During the past 25 years, medical imaging research has progressed in both scope and quality. Factors intrinsic to the specialty and changes occurring in medicine and society have fostered imaging research development. The advent of new, computer-based technologies that can be brought to bear on research, the increasing sophistication of researchers, and the greater availability of extramural funding have been primary factors in the promulgation of research improvements. Radiology researchers have the opportunity to play an important role in the genesis of the molecular medicine of the future. Whether they do so is dependent on whether radiologists identify necessary resources, new researchers receive appropriate training, and investigators are willing to think differently than they have in the past about the capabilities of imaging.

X-ray Imaging
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
Magnetic Resonance Imaging
Positron Emission Tomography
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...
Brain Imaging
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).
