Rodent brains retain gadolinium after repeated administration of GBCA a year after injection

Researchers from the Guerbet Group and the University of Münster in Germany recently found that 75 percent of the total gadolinium found in the cerebellum of rats after the injection period of the linear contrast agent gadodiamide was still retained after one year.

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.

Officially sworn in this past October as the Director of the National Cancer Institute (NCI), Ned Sharpless, MD, believes that artificial intelligence will probably be in the future of cancer care.

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.

Surveillance intensity doesn’t equate to earlier detection, improved survival in colorectal cancer patients

A recent JAMA study from University of Texas MD Anderson Cancer Center researchers found no correlation between intensity of post-treatment surveillance and detection of recurrence or survival in patients with stage I, II or III colorectal cancer (CRC).

Robot-assisted imaging may hasten treatment for prostate cancer patients

Researchers have successfully used robot-assisted multispectral-fluorescence imaging to distinguish between healthy and diseased lymphatic flow patterns.

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.

Around the web

A total of 16 cardiology practices from 12 states settled with the DOJ to resolve allegations they overbilled Medicare for imaging agents used to diagnose cardiovascular disease. 

CCTA is being utilized more and more for the diagnosis and management of suspected coronary artery disease. An international group of specialists shared their perspective on this ongoing trend.

The new technology shows early potential to make a significant impact on imaging workflows and patient care.
