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. 

Intermountain docs image, model and save patient’s kidney

Using CT scans to create a 3-D printout of a patient’s kidney for presurgical planning, a urologist and a radiologist at Intermountain Healthcare in Utah have led a care team in removing a complicated tumor while preserving the actual kidney.

Gray matter differences imaged in diabetic teens

Prior research has established that teenagers with type 2 diabetes have different gray-matter volumes and poorer cognitive function than their nondiabetic peers. A new MRI-based study at Cincinnati Children's Hospital Medical Center has imaged the particular regions in which the differences occur.

Diffusion MR proves adept at predicting concussion outcomes

Diffusion tensor MRI can be used to separate concussion patients who are likely to fully recover within a year from those who are likely to suffer longer-term effects, pointing to the most appropriate treatment pathways for each. 

‘Hyperscanning’ shows sex differences in the brains of pairs asked to cooperate with one another

Forgoing fMRI in favor of “hyperscanning” with near-infrared spectroscopy, or NIRS, Stanford researchers have uncovered intriguing differences in brain activity between males and females who have been asked to cooperate. 

A monarch is wowed by the wonders of modern medical imaging

The Queen of England and the Duke of Edinburgh have given two thumbs up to a new and sprawling neuroimaging center in Wales. 

Sheryl Crow named Hologic's national celebrity spokesperson for breast cancer educational campaign

Hologic, a developer, manufacturer and supplier of diagnostic products, medical imaging systems and surgical products, has announced a partnership with singer, songwriter and breast cancer survivor Sheryl Crow.

Researchers image iron distribution in Alzheimer brains

An Australian chemist exploring the role of iron levels in Alzheimer’s disease has led an international effort to map these levels in deceased brains and compare them with iron levels in non-Alzheimer’s brains.

MRI may illuminate new avenues for schizophrenia treatment

Using MRI with covariance analysis, researchers have revealed tissue increases over time in the brains of patients with schizophrenia. The increases suggest these brains may be compensating for lost capacity and perhaps trying to protect themselves against further damage. 

Around the web

GE HealthCare designed the new-look Revolution Vibe CT scanner to help hospitals and health systems embrace CCTA and improve overall efficiency.

Clinicians have been using HeartSee to diagnose and treat coronary artery disease since the technology first debuted back in 2018. These latest updates, set to roll out to existing users, are designed to improve diagnostic performance and user access.

The cardiac technologies clinicians use for CVD evaluations have changed significantly in recent years, according to a new analysis of CMS data. While some modalities are on the rise, others are being utilized much less than ever before.
