Dear CT Insider,
It's crucial to assess patients' preoperative cardiovascular risk before they undergo noncardiac surgery, but doing so can be challenging. However, many of these patients have had nongated CT exams, and a group of researchers from New York University Grossman School of Medicine in New York City is suggesting that information from these scans could help clinicians estimate the prevalence and severity of a patient's coronary artery calcium (CAC) before surgery -- and thus assess the person's risk of adverse events afterward. We're highlighting these findings in this edition's featured article.
Navigate to our CT content area for more important news, including a JAMA Oncology report that explores why lung cancer incidence continues to increase among younger women, a study that describes how ultrahigh-resolution CTA bests conventional CTA for detecting aneurysms, and research that outlines how three specific CT findings can help predict a patient's need for surgery after sustaining a traumatic brain injury.
We're also reporting on a study that supports the benefits of regular lung cancer screening with low-dose CT (LDCT), especially for women, as well as one that shows how AI-boosted opportunistic LDCT can support the evaluation of bone mineral density.
As for more on the AI side, we're covering studies that describe how the use of deep learning with chest CT can measure an individual's chest fat and thus help predict risk of heart failure and how, when it's used with pelvic CT imaging, it can help categorize acute appendicitis.
CT is a tried-and-true tool in the radiology department's kit. We invite you to stay up-to-date on its uses and innovations by visiting our CT content area regularly, and if you have CT-related topics you'd like us to consider, please contact me.
