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.

The approach—called GammaTile—involves placing small radiation seeds at a tumor site during surgery.

New radiation therapy treatment stalls recurrence while sparing healthy tissue in patients with brain cancer

The treatment has the potential to “extend lifespans and improve quality of life” in patients with brain cancer, according to experts at UC San Diego Health.

Time-of-flight intracranial MRA at 5T comparable to 7T, new analysis shows

A new paper published in Radiology details an analysis of 3-T, 5T and 7T MRI to determine which system could achieve the best intracranial vascular image quality.

MRI exams reveal the impact of steroid use on the brain

Experts involved in the study suggest that their findings could help explain the neuropsychiatric effects seen in many patients who are prescribed steroids long-term.

Can PTSD cause dementia? Imaging of 9/11 first responders suggests it's possible

Compared to World Trade Center responders who have not been diagnosed with PTSD, those who had received the diagnosis were observed to have decreased fractional anisotropy of white matter tracts on their brain MRIs.

Poor midlife health leads to advanced brain aging, MRI analysis shows

Though the participants’ actual ages ranged from 69 to 72 years old, the experts’ predictive analysis revealed their estimated current brain ages to be between 46 and 93.

Positron, a New York-based nuclear imaging company, will now provide Upbeat Cardiology Solutions with advanced PET/CT systems and services. 

The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.

CMS has more than doubled the CCTA payment rate from $175 to $357.13. The move, expected to have a significant impact on the utilization of cardiac CT, received immediate praise from imaging specialists.
