For male patients increased left-ventricular mass (LVM) was predictive of a cardiovascular event, while LVM-to-volume ratio was predictive in female patients
Cardiovascular disease (CVD) is a major cause of death in people worldwide. CVD is characterized by structural alterations in the size and shape of the myocardium over the course of the disease, termed left ventricular (LV) remodeling.

The Anatomy of a Virtual Imaging TrialVirtual imaging trials are based on the simulation of human anatomy, imaging modalities and image interpretation, which parallel the components of real-life imaging trials. Depending on the imaging task to be assessed, each component will include various models to be simulated.

Whether we’re aware of them or not, biases are everywhere—and AI is no exception. “An AI algorithm reflects the data it is trained on,” said Bradley J. Erickson, MD, PhD, professor of radiology at the Mayo Clinic in Rochester, MN. “This means that if a use case doesn’t have the same statistics as the training data, the algorithm tends to give answers that reflect the latter.” This isn’t the result of some desire to intentionally harm a particular group.

This is the final story in a series of RSNA News articles addressing issues facing private radiology practices. Read the first and second story of the series. Private equity investment in radiology practices is nothing new. But the impact such investments have on the practice and on the radiologists is very much open to debate. “Investor-backed entities can be a good idea if done correctly and for the right reasons,” said Gavin P.

Thyroid nodules are a common clinical problem. While most aren’t serious, a small percentage are cancerous. The challenge is to determine what’s benign and what’s malignant. “Ultrasound is the imaging technique most often used to assess the probability of malignancy, as well as to guide biopsy,” said Terry S. Desser, MD, professor of radiology at Stanford University School of Medicine in Stanford, CA.

According to the Alzheimer’s Association, amnestic mild cognitive impairment(aMCI), the subtype of MCI that primarily affects memory, may cause a person to begin forgetting important information they would previously have easily recalled, such as appointments, conversations, or recent events. Not all aMCI patients will progress to dementia, and those that do have heterogeneous clinical progression, making it difficult to identify individual patients at highest risk.

Often exhibiting no symptoms until an advanced stage, prostate cancer remains a difficult disease to detect. While screening can help, current practices, which test for prostate-specific antigen (PSA) levels, lack specificity and can be elevated for reasons other than cancer. MRI has the potential to close this screening gap.
