FDA approves a new ultrasound imaging agent

The U.S. Food and Drug Administration has approved Lumason (sulfur hexafluoride lipid microsphere) for patients whose ultrasound image of the heart (echocardiograms) are hard to see with ultrasound waves.

Lumason is a contrast agent made up of gas-filled microbubbles (or… Read more →

Fluorescent, Magnetic Nanoparticles Aid Bioimaging

Nanoparticles that fluoresce to enable tracking in the body can also be precisely manipulated with magnetic fields.

Manipulating the particles with electromagnets is key to using them in biological research because the tiny particles could otherwise get lost in the… Read more →

Photoacoustic method enables noninvasive, dynamic imaging of small intestine

Nanoparticles suspended in liquid, ingested by patients, promises to enable photoacoustic tomography (PAT) imaging for a noninvasive, real-time view of the small intestine.1 The advancement could help doctors better identify, understand, and treat gastrointestinal ailments such as irritable bowel syndrome,… Read more →

Neuroimaging technique identifies concussion-related brain disease in living brain

An experimental positron emission tomography (PET) tracer is effective in diagnosing concussion-related brain disease while a person is still alive. A new study suggests that an experimental radiolabeled compound, which is designed to latch onto a protein called tau that… Read more →

New Fluorescence Marker Enhances Bio-Imaging

A new line of red-shifted fluorescent tissue markers may enhance deep-tissue imaging.

A team from the German Research Center for Environmental Health, in collaboration with the Max Planck Institute for Neurobiology and the Federal Institute for Materials Research and Testing,… Read more →

Radioactive tracer with PET MRI imaging helps prostate cancer patients avoid unnecessary surgery

Researchers at the Norwegian University of Science and Technology are pioneering the use of a radioactive tracer in combination with PET MRI imaging to help some prostate cancer patients avoid lengthy and unnecessary surgery.

Severely ill prostate cancer patients are… Read more →

Versatile nanoparticles offer wide variety of diagnostic and therapeutic applications

Kit Lam and colleagues from UC Davis and other institutions have created dynamic nanoparticles (NPs) that could provide an arsenal of applications to diagnose and treat cancer. Built on an easy-to-make polymer, these particles can be used as contrast agents… Read more →

Nanodiamond tech lights new path in medical diagnostics

Earlier this month TechCrunch featured a look at a company that wants to make a difference in finding cancer before it spreads using nanodiamond-based technology. The idea is that nanodiamonds can detect molecular abnormalities at an early stage, and as… Read more →

Near-infrared imaging helps make cancer glow to improve surgical outcomes

A team of researchers at the University of Pennsylvania (Philadelphia, PA) has developed a new method to help surgeons see an entire tumor in a patient, increasing the likelihood of a positive outcome. Their approach relies on an injectable dye… Read more →

Bagasse-derived fluorescent carbon dots for bio-imaging

Carbon quantum dots (CDs) are the new stars of carbon nanomaterials. This is thanks to their numerous potential applications in biomedical imaging, photocatalysis, sensing and optoelectronic devices. Despite numerous achievements in this area, finding alternative, simple and low-cost routes to… Read more →
