A new medical imaging method could help physicians detect cancer and other diseases earlier than before, speeding treatment and reducing the need for invasive, time-consuming biopsies. The potentially lifesaving technique uses nanotechnology and shortwave infrared light to reveal small cancerous tumors and cardiovascular lesions deep inside the body.

X-ray phase tomography is an imaging technique that uses penetrating X-rays to create volumetric views through "slices" or sections of soft biological tissues, such as tumors, and it offers strongly enhanced contrast compared to conventional CT scans. Yet scientists still do not know which X-ray phase tomography methods are best suited to yield optimized results for a wide variety of conditions.

A graphene, one-atom-thick microelectrode now solves a major problem for investigators looking at brain circuitry. Pinning down the details of how individual neural circuits operate in epilepsy and other brain disorders requires real-time observation of their locations, firing patterns, and other factors.

Conventional wisdom says that a lot of medical care in the United States is 'defensive medicine' prescribed because doctors want to protect themselves from the risk of malpractice lawsuits. But a new study that examines three states where emergency room doctors were given immunity from malpractice claims finds that such protections do little to reduce the cost of medical care.

A novel technique that reduces image degradation caused by respiratory motion during a PET scan was developed through a recent study. PET scanning is routinely used to detect cancer and heart conditions. The new technique is based on bioimpedance measurement and it allows for image reconstruction at a specific phase of the patient's breathing pattern. This, in turn, makes it possible to reduce image degradation caused by motion.
