On the other, a group of researchers suggested that screening mammography has a minor effect on mortality and breast imaging may cause more harm than benefit.

Medtronic has received CE mark approval for its 31 mm Medtronic CoreValve system, a transcatheter aortic valve.

Positron, a molecular imaging company specializing in nuclear cardiology, has relocated its PosiRx manufacturing, product research and development facility. The new office is approximately three miles from its current Fishers, Ind., location.

A pair of visual ultrasound markers may help physicians better determine which patients with asymptomatic carotid stenosis face a higher stroke risk, and better determine which patients might benefit from carotid endarterectomy (CEA), according to a study published online Aug. 17 in Neurology.

Researchers at the Biodesign Institute at Arizona State University have found a way to get molecular binding agents to act like antibodies and, in the process, optimize the binding agents affinity for targeted proteins. The development revealed important nuances of protein function and could lead to better diagnosis and treatment for a range of diseases. The researchers published their findings Aug. 16 in the journal ChemBioChem.

NeuroLogica has received CE Mark approval for its portable inSPira HD SPECT camera.
