Advanced Visualization

A flexible x-ray detector developed by researchers at the University of Surrey's Advanced Technology Institute in the U.K. could lead to the development of other real-time imaging machines that would decrease screening errors and harm to patients.

A specialized x-ray diffraction lab at the Illinois Institute of Technology (IIT) in Chicago is using fiber diffraction, allowing scientists to study structural tissue changes in the human heart, brain and even dinosaur fossils. The technique may help physicians track injury-related tissue damage and identify risk areas, according to an American Crystallographic Association release from July 22.

Health Imaging recently spoke with father-and-son scientists Anthony Butler, PhD, and Phil Butler, PhD, about the MARS spectral x-ray scanner, a new 3D color x-ray machine that has gained international attention since it successfully imaged its first human subject last week.

The MRI-based technique of quantitative susceptibility mapping can monitor iron levels in the brains of multiple sclerosis (MS) patients, allowing physicians to identify those at a higher risk of developing physical disability, according to a recent Radiology study.  

Technological advancements over the past three decades have placed 3D MRI on par with its 2D counterpart in depicting cartilage defects, according to a study published in Radiology. With specific alterations, the modality may be able to replace traditional MRI.

Researchers used single-photon emission computed tomography (SPECT) to assess the immune system recovery of macaque monkeys with an HIV-like infection. The work may help researchers understand recovery in humans after HIV treatment.

Evelina London Children's Hospital in the U.K. recently invested in three ultrasound scanners that can detect heart defects and other abnormalities in fetuses as early as 12 weeks old, according to an article published July 13 by The Standard.

A team of U.S. researchers has uncovered the exact point when normal, healthy protein becomes toxic but has yet to form tangles. Experts believe the findings could be a target for developing Alzheimer's treatments.

A 3D color medical scanner invented by father and son scientists in New Zealand recently imaged its first human subject, according to a news release from the University of Canterbury in New Zealand.

A Pennsylvania farmer suffering from essential tremors in both hands recalled how his experience undergoing focused ultrasound treatment was risky but ultimately worth it, according to a July 9 article by NPR.

A novel PET imaging method may improve evaluation of joint inflammation in rheumatoid arthritis patients by targeting translocator protein (TSPO) expression in joint lining tissue, according to research published online in the July issue of The Journal of Nuclear Medicine.

A new ultrasound prototype utilizing an optical—rather than electronic—system may provide flexibility in simultaneously pairing the modality with other imaging techniques, such as MRI. Experts say it could provide doctors more options for using ultrasound to diagnose and treat patients.
