Artificial Intelligence

Artificial intelligence (AI) is becoming a crucial component of healthcare to help augment physicians and make them more efficient. In medical imaging, it is helping radiologists more efficiently manage PACS worklists, enable structured reporting, auto detect injuries and diseases, and to pull in relevant prior exams and patient data. In cardiology, AI is helping automate tasks and measurements on imaging and in reporting systems, guides novice echo users to improve imaging and accuracy, and can risk stratify patients. AI includes deep learning algorithms, machine learning, computer-aided detection (CAD) systems, and convolutional neural networks.

3D virtual reality simulator shows surgical training promise

A virtual reality neurosurgery simulator seems poised to provide a cost-effective alternative to conventional surgical training approaches, according to an analysis of two initial training tasks completed on prototypes and published in the September issue of Neurosurgery.

Gender differences: SUVmax may predict survival in men w/ lung cancer, not women

Among a cohort of men and women with surgically treated early non-small cell lung cancer, maximum standard uptake value (SUVmax) independently predicted overall survival for men, but not for women, according to a study published online Sept. 14 in Journal of Nuclear Medicine.

MRI reveals weak links to amygdala in patients with anxiety

The brains of people with generalized anxiety disorder have weaker connections between the anterior cingulate cortex, the brain structure that controls emotional response, and the amygdala, according to a study published Sept. 4 in Archives of General Psychiatry. The findings suggest the brain's "panic button" may stay on due to lack of regulation.

High marks for telestroke evaluation

Medical images viewed on smartphones can be effectively used to remotely evaluate stroke patients through telemedicine, according to a study published online ahead of print in Stroke.

Balancing act

In healthcare, the ideal technologies deliver optimal quality while holding the line on costs. Accuracy is key. Achieving these occasionally competing outcomes represents a challenging, but wholly doable, balancing act.
