Nuke-med tracking aids management of advanced biliary tract cancer

Rare but aggressive, cancers of the bile duct can be added to the list of carcinomas for which PET scanning with the radiotracer 18F-FDG adds diagnostic and/or prognostic value, according to the authors of a study running in the August edition of the Journal of Nuclear Medicine.

Interactive 3D anatomic holograms in the works

Work is underway at UC-San Francisco to develop an augmented-reality system for planning oncologic interventions using 3D models. The models are not 3D printouts, as you might expect. They’re 3D holograms created from patients’ CT scans and superimposed, a la Pokémon Go, in real-world settings.

Prostate cancer may face new foe in photoacoustic/ultrasound imaging

Researchers at Japan’s National Defense Medical College have developed an ultrasound-equipped photoacoustic imaging (PAI) system that shows potential for imaging the angiogenesis, or formation of troublesome new blood vessels, in prostate cancer.

CT colonography coverage hoists screening rates

Individuals who have insurance covering CT colonography are almost 50 percent more likely to get screened for colon cancer by either that option or colonoscopy—both of which can help prevent as well as detect cancer—than those who lack such coverage, according to a study published online July 11 in Radiology.

Scientist takes aim at tumors with ultrasound, magnets and microbubbles

A biomedical engineer at the University of Oxford has developed a way to finely target tumors, and only tumors, using drug-delivering microbubbles activated by ultrasound and magnetic fields. Her work has caught the eye of Wired UK.

Brain ultrasound during tumor surgery matches pre-op MRI guidance and then some

Italian researchers have shown how surgeons resecting glioblastomas, the most common and aggressive brain tumors, can use contrast-enhanced ultrasound to guide their view of tumor location, morphologic features, margins and dimensions in real time and for the duration of the entire surgery.
