Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography,  and the nuclear imaging modalities of PET and SPECT.

MRI scans help researchers understand the biology of autism

With the help of MRI, San Diego State University researchers found the amygdala of children on the autism spectrum disorder (ASD) had weaker connections with some regions of the brain compared to “typically developing” children within the same age group.

Combining CT, pathology results can improve lung ground glass diagnosis

A new study published in Experimental and Therapeutic Medicine found combining a CT scan with pathology results would improve the diagnosis and differential diagnosis of lung ground-glass opacity (GGO).

MRI shows potential to correct slow gastric emptying, gastroparesis

Researchers have used MRI to show the impact of sending electrical pulses to the vagus nerve in an attempt to correct gastrointestinal problems and provide “more precise treatment” that pharmaceutical therapies and diet have not achieved.

MRI markers of vascular brain injury associated with higher risk of stroke, dementia

Elderly patients with vascular brain injury (VBI) who carry MRI markers—including white matter hyperintensities of presumed vascular origin, MRI–defined covert brain infarcts, cerebral microbleeds and perivascular spaces—have an increased risk of stroke, dementia and death, according to new research published Oct. 22 in JAMA Neurology.
