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. 

4D lung imaging platform gives clearer vision for early detection

Professor Andreas Fouras of Monash University has developed a four-dimensional lung scanning technology platform, helping physicians to detect abnormal lung functions early, reports News Medical.

PET imaging gives insight into a brain with depression

Scientists from the RIKEN Center for Life Science Technology (CLST) have developed a new PET scan that is able to analyze neuron proliferation in the brain's subventricular and subgranular zones of the hippocampal dentate gyrus, the areas most affected by depression.

Imaging tool shows oxygen in human tissue like never before

Oxygen, the air we breathe and the foundation of life, remains mysterious in terms of seeing it working through our tissues. That is until researchers developed a new tool to show us just how oxygen travels to our tissue.

Radiologists imaging and biopsying prostate cancers with notable success

A radiology team at Virginia Commonwealth University Medical Center is using advanced multiparametric MRI to diagnose difficult prostate cancers with upwards of 90 percent accuracy—and then perform targeted biopsies guided by MRI and ultrasound. 

A clearer view into prostate cancer with new imaging tool

The new method used to detect androgen receptors and active splice variants could mean better and faster care for patients suffering from prostate cancer. 

Q&A: Aspect Imaging CEO sees big potential in smaller MRI machines

Aspect Imaging, a design and producer of MRI systems, have developed an MRI machine that is more compact than many contemporary machines.

Vascular disruption—not amyloid accumulation—is Alzheimer’s first observable brain change

A new analysis of big data largely based on thousands of MR and PET images has shown that changes in blood flow to and within the brain precede amyloid build-up in Alzheimer’s patients. 

Concussions alter brains well past point of full-function regain

Amplifying research from earlier this year showing that the anatomic effects of traumatic brain injury persist long after observable symptoms subside—potentially long enough to increase risk for Alzheimer’s—a new diffusion MRI study has shown white matter changes in the brains of athletes six months after a concussion event.  

Around the web

Harvard’s David A. Rosman, MD, MBA, explains how moving imaging outside of hospitals could save billions of dollars for U.S. healthcare.

Back in September, the FDA approved GE HealthCare’s new PET radiotracer, flurpiridaz F-18, for patients with known or suspected CAD. It is seen by many in the industry as a major step forward in patient care. 

After three years of intermittent shortages of nuclear imaging tracer technetium-99m pyrophosphate, there are no signs of the shortage abating.
