Advanced Visualization

 

Researchers, led by scientists at the University of Cambridge, have found a correlation between interconnectivity of brain regions and individual intelligence using brain MRI, according to a study published online in Neuron.

Researchers explored using MRI to distinguish age-related changes and as a tool to evaluated aging thigh muscles. The study used four quantitative MRI techniques: intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI), diffusion-tensor imaging (DTI), multiecho Dixon water-fat imaging and dynamic contrast material–enhanced (DCE) MR imaging.

New technology developed at New York’s Binghamton University could change the way clinicians detect heart disease with MRI scans, research published in the journal Colloid and Surfaces B: Biointerfaces suggests.

Around this time of year, people are reminded it’s better to give than receive. According to recent research using functional MRI (fMRI) to examine brain function, this is true when it comes to giving thanks. Gratitude may be good for mental health and increase overall feelings of altruism.

Computer tomography (CT) has produced stunning images and improved diagnosis and treatment of myriad health complications. A German research team has developed an imaging technique called nano-CT that produces images at resolutions up to 100 nanometers, a marketed improvement from the 500 nm in traditional CT methods.

Multimodal MRI of the brain’s visual system can catch Parkinson’s early on

Early-stage Parkinson’s disease shows up on MRI in parts of the brain connected to the eyes, which may help clinicians confirm the diagnosis, follow the disease’s progression and monitor the patient’s response to drug treatments, according to a small Italian study published online July 11 in RSNA’s Radiology.

As a metastasis finder, whole-body MRI wins some, loses some

Whole-body diffusion-weighted MRI (DWI) very nearly matches conventional imaging when it comes to finding metastases in the liver and bones of cancer patients. That’s the good news for whole-body DWI.

3D scanning system captures T. rex, bites into upfront costs

3D imaging is an exciting niche in the field of medical imaging. One obstacle to further exploration, though, is the hefty upfront costs to acquire the necessary hardware and software. Researchers have developed a promising 3D imaging system that costs a few hundred dollars—a mere fraction of the cost of many CT-based systems.
