Brain diffusion study uncovers different connectivity patterns for high intelligence among boys and girls
Before the dawn of political correctness, there was a time when girls were made of sugar and spice and everything nice, and boys were made of snips and snails and puppy dog tails. Now, functional MRI is confirming that boys and girls really don't think alike. Brain structures and functions that facilitate intelligence in girls are different for boys.
Whole-body diffusion-weighted MRI has been introduced to complement and possibly compete against whole-body FDG PET and whole-body anatomical MRI for staging cancer metastasis.
More is better and all but inevitable in medical imaging. In CT, more means slices. In MR, it’s channels for receiving radiofrequency signals. These currently number 32 on the most advanced commercially available systems. But a replacement for that benchmark is in the works.
Playing off the continuously moving table built into TimCT, Siemens Medical Solutions proclaimed “Tim (Siemens’ total image matrix) is on the move” at the International Society for Magnetic Resonance in Medicine meeting in Berlin. The company is featuring clinical results from its seven luminary installations of the technology in MR angiography and central nervous system imaging.
Volumetric and highly specialized imaging techniques will expand the clinical horizons of MR, according to GE Healthcare. Technologies that improve the speed of data acquisition and processing will make them practical.
Toshiba Medical Systems Europe is going toe-to-toe with the established high-end vendors at 1.5T during the International Society for Magnetic Resonance in Medicine meeting in Berlin. Its high-performance Vantage Atlas MR, shown several months earlier at the RSNA meeting as a work-in-progress, became a commercial reality with the first system installed and operating in March at a hospital in a Paris suburb and another more recently at an outpatient facility in Las Vegas.
An Emory University researcher has established the diagnostic power of a simple contrast-enhanced MRI protocol that informs surgeons about the presence and extent of hepatocellular cancer in cirrhotic livers that are scheduled for transplantation.
Unlike tests that provide thresholds such as good or bad cholesterol levels, MR scans are open to interpretation. Early steps toward quantitation have focused on measuring tumor size and volume as indicators of cancer progression or patient response to therapy. Philips is going further.
The differing interests of clinical and basic science researchers are apparent in the work of the finalists for Young Investigator Awards at this year’s ISMRM/ESMRMB meeting.
