Two Egyptian mummies pinned unidentifiable by archaeologists have recently been given three-dimensional (3D) faces with the help of CT imaging and computer animation thanks to researchers at Johns Hopkins University in Baltimore, according to a report published Oct. 23 by The Baltimore Sun.

Engineers from MIT in Cambridge, Massachusetts have developed a non-invasive MRI sensor no bigger than a penny that can detect and measure electrical activity or optical signals in the brain, according to a recent MIT news release. The research was published online Oct. 22 in Nature Biomedical Engineering.

The technique is able to map the structure of small organic molecules, such as pharmaceuticals and hormones, with electron diffraction imaging—commonly used to chart larger proteins, according to a report published Oct. 19 by Science Magazine.

The color scale used to optimize image interpretation has a measurable diagnostic effect on the interpretation of computed tomography perfusion (CTP) exams and apparent diffusion coefficient (ADC) images, according to an Oct. 15 study published in Clinical Radiology.

MRIguidance, a spin-off company of the University Medical Center Utrecht in the Netherlands, is developing an advanced MRI software that can characterize both soft tissue and bone without the use of radiation, according to a company news release published Oct. 16.

In patients with liver cirrhosis, four-dimensional (4D) flow MRI can help indicate the risk of bleeding in gastroesophageal varices and reduce the need for invasive endoscopy procedures, wrote authors of an Oct. 16 Radiology study.

With the help of diffusion spectrum imaging, scientists from the University at Buffalo in New York are creating models to better understand how brain structure affects language-based performance tasks.

Using a mixed-reality holographic computer headset, neurosurgeons can more accurately perform external ventricular drain (EVD) insertion, according a new study out of Beijing published in the Journal of Neurosurgery.

Using microscopic imaging, researchers from the University of Calgary in Alberta, Canada have shown how the kidneys negatively respond to contrast dyes used during various medical tests and procedures, according to a university press release published Oct. 15.

Novel research led by Stephen Smith, PhD, from the Wellcome Center for Integrative Neuroimaging at the University of Oxford in the U.K.—whose team compared genetic data to 10,000 brain MRI scans from the U.K. Biobank project—gives insight into the genetic makeup of the human brain relevant to neurological and psychiatric disorders.

Determining how highly specialized surgeons and physicians learn new skills or respond to a stressful situation may be unveiled with recently published neuroimaging research, the Wall Street Journal reported on Oct. 3.

“We wanted to develop an anthropomorphic phantom head to help us better understand these issues by providing a safer way to test the imaging. We use the device to analyze, evaluate and calibrate the MRI systems and instrumentation before testing new protocols on human subjects,” Tamer Ibrahim, PhD, and co-creator said.
