Neuroimaging

Neuroradiology is a branch of medical imaging focused on spotting abnormalities of the central and peripheral nervous system, spine, head and neck. These highly trained doctors use CT, MRI, X-ray and other techniques to diagnose strokes, tumors, aneurysms and other neurological conditions.

Depression

Neuroimaging analysis suggests that the brains of patients with depression are not so different after all

“Results of this case-control study suggest that even for maximum univariate biological differences, deviations between patients with MDD and healthy controls were remarkably small," experts shared in JAMA Psychiatry.

The University of Southern California was among the first imaging centers in the U.S. to install a 7T MRI. This high-end part of the MRI market is small and is mainly made up of academic research centers. The main MRI market is made of of 1.5T systems, but there is rising demand for 3T, which Signify research may eventually become the standard for MRI.
