NIBIB-funded researchers have developed and tested an ultrasound-based approach called intravascular photoacoustic imaging for improved analysis of arterial blockages known as plaques. The system takes precise three-dimensional images of plaques lining arteries and identifies deposits that appear to be "unstable" and most likely to rupture and cause heart attacks. Such critical information could guide early and targeted intervention before the onset of acute cardiovascular events. Read more at Purdue University News.

NIBIB grantee Lihon Wang of Washington University in St. Louis has developed the world’s fastest receive-only 2-D camera, a device that can capture events up to 100 billion frames per second. That’s orders of magnitude faster than any current receive-only ultrafast imaging techniques, which are limited by on-chip storage and electronic readout speed to operations of about 10 million frames per second. The camera could enhance deep imaging of biological tissues. Read more at

Diagnosing HIV and other infectious diseases presents unique challenges in remote locations that lack electric power, refrigeration, and trained health care staff. To address these issues, researchers funded by the National Institutes of Health have developed a low-cost, electricity-free device capable of detecting the DNA of infectious pathogens, including HIV-1. The device uses a small scale chemical reaction, rather than electric power, to provide the heat needed to amplify and detect the DNA or RNA of pathogens present in blood samples obtained from potentially infected individuals.

Interest in mapping white matter pathways in the brain has peaked with the recognition that altered brain connectivity may contribute to a variety of neurologic and psychiatric diseases. Diffusion tractography has emerged as a popular method for postmortem brain mapping initiatives, including the ex-vivo component of the human connectome project, yet it remains unclear to what extent computer-generated tracks fully reflect the actual underlying anatomy.

A research team including NIBIB-funded chemical engineers have developed a new implantable tissue scaffold polymer capable of releasing bone growth factors for several weeks. When applied to bone injuries or defects, the new polymer helps the body quickly form new bone that looks and acts just like the original. The technology offers an improvement over the current practice of transplanting bone from another part of the patient's body. Read more in Boston Magazine.

NIBIB grantee Ge Wang, director of the Biomedical Imaging Center at Rensselaer Polytechnic Institute, was recently named a fellow by the American Association for the Advancement of Science (AAAS). Wang wrote pioneering papers on the first spiral cone-beam CT algorithm that enables spiral cone-beam CT imaging, which is used in almost all hospitals worldwide.

Shortly before NIBIB was founded, Health Affairs published a physician survey asking about the most important medical innovations of the previous 25 years.  Doctors rated MRI and CT scanning as the most significant developments ahead of twenty-nine other innovations including statins, hip replacements and bone marrow transplants.

When individuals suffer a spinal cord injury, paralysis is only a part of the major impact on quality of life. Often they also lose bladder control, which frequently causes infections that can lead to kidney damage. To address this problem, scientists used their groundbreaking spinal stimulation technology to enable spinal cord- injured rats to empty their bladders more fully and in a timelier manner. The promising results achieved in rats represent a significant step towards deployment of this novel approach in humans with paraplegia.

The National Institute of Biomedical Imaging and Bioengineering (NIBIB) is delighted to congratulate two of its research grantees for their election to the prestigious National Academies’ Institute of Medicine (IOM). Gordana Vunjak-Novakovic, Ph.D., at Columbia University, New York City, and W. Mark Saltzman, Ph.D., at Yale University, New Haven, Connecticut are among the 70 new members that were announced at the IOM’s 44th annual meeting in Washington on October 20.
