Behind the Green Door secure communications center with SIPRNET, GWAN, NSANET, and JWICS access. According to the U.S. Department of State Web Development Handbook, domain structure and naming conventions are the same as for the open internet, except for the addition of a second-level domain, like, e.g., "sgov" between state and gov: openforum.state.sgov.gov.

MRI scanners use strong magnetic fields, magnetic field gradients, and radio waves to form images of the organs in the body. MRI does not involve X-rays or the use of ionizing radiation, which distinguishes it from computed tomography (CT) and positron emission tomography (PET) scans. MRI is a medical application of nuclear magnetic resonance ...
Whole body imaging (WBI) refers to the display of the entire body in a single procedure. In medical imaging , it may refer to full-body CT scan or magnetic resonance imaging . It may also refer to different types of Full body scanner technologies used for security screening such as in airports.
Modern 3 Tesla clinical MRI scanner.. Magnetic resonance imaging (MRI) is a medical imaging technique mostly used in radiology and nuclear medicine in order to investigate the anatomy and physiology of the body, and to detect pathologies including tumors, inflammation, neurological conditions such as stroke, disorders of muscles and joints, and abnormalities in the heart and blood vessels ...
Spoiled gradient recalled echo (GRE), fully flow compensated, long echo time, combines phase image with magnitude image [9] Detecting small amounts of hemorrhage (diffuse axonal injury pictured) or calcium. [9] Inversion recovery Short tau inversion recovery: STIR: Fat suppression by setting an inversion time where the signal of fat is zero. [10]
On July 3, 1977, the first MRI body exam was performed on a human being [28] (the first human scan was performed by Peter Mansfield's team in Nottingham a year earlier, on fellow author Andrew Maudsley's finger). It took almost five hours to produce one image: a 106-voxel point-by-point scan of Larry Minkoff's thorax. The images were ...
As with any test that screens for disease, the risks of full-body CT scans need to be weighed against the benefit of identifying a treatable disease at an early stage. [6] An alternative to a full-body CT scan may be Magnetic resonance imaging (MRI) scans. MRI scans are generally more expensive than CT but do not expose the patient to ionizing ...
Body scan may refer to: 3D body scanning, for measuring the body, used in Ergonomics; Full body scanner in airport security; Full-body CT scan, in medical imaging; The mindfulness practice of body-scanning
