Diagnostic Imaging

Radiologists use diagnostic imaging to non-invasively look inside the body to help determine the causes of an injury or an illness, and confirm a diagnosis. Providers use many imaging modalities to do so, including CT, MRI, X-ray, Ultrasound, PET and more.

Diffusion-weighted MRI beats PET/CT in predicting survival of cancer patients receiving radioembolization

A group of German researchers found diffusion-weighted (DW) MRI provided superior prognostic information compared to PET/CT in liver cancer patients who underwent 90Y radioembolization and proved more accurate in predicting overall survival in these patients.

fMRI may improve predictions of cognitive decline in MS patients

Using functional MRI (fMRI), researchers from VU University Medical Center in Amsterdam found a correlation between white matter brain damage and atrophy in multiple sclerosis (MS) patients—a primary factor of cognitive impairment in patients with the disease.

Fetal MRI can ID brain malformation earlier than traditional imaging

New research has found fetal MRI can reliably identify holoprosencephaly as early as 18 weeks into pregnancy, providing added time for parents to understand and prepare for the condition.

'Erasable' MRI contrast agents could simplify diagnostic imaging, disease detection

Researchers at CalTech are developing "erasable" contrast agents that can "blink off" on command during an MRI to reveal their exact location inside the body, according to a press release from the California Institute of Technology.

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.
