In a recently published prospective study comparing photon-counting detector computed tomography (PCD CT) versus energy-integrating detector CT (EID CT) in patients with persistent symptoms after COVID-19 infection, researchers found that PCD CT discovered additional lung abnormalities in half of the study participants.

Emerging research suggests that a ketogenic diet reduces the uptake of 18F-fluorodeoxyglucose (18F-FDG) in brain positron emission tomography (PET) scans with a more pronounced effect in the precuneus.

In a video interview discussing one of her recent lectures at the Radiological Society for North America (RSNA) conference, Nina Kottler, M.D., M.S., noted how the combination of artificial intelligence (AI) and radiologist experience can help mitigate bias limitations with the development of AI algorithms as well as educational biases inherent to a radiologist’s training and experience.

The artificial intelligence (AI) software Saige-Density™ reportedly provides automated assessment of breast density during mammography exams.

Reportedly the first targeted molecular imaging agent to provide intraoperative illumination of lung cancer, Cytalux (pafolacianine) helped identify clinically significant events in more than 50 percent of patients undergoing surgery for confirmed or suspected pulmonary nodules, according to Phase 3 trial data presented earlier this year at the American Association for Thoracic Surgery Annual Meeting.

Having interests outside of one’s chosen profession provides more of a multifaceted perspective and potentially more door-opening opportunities in the future.

In addition to summary sensitivity and specificity of 92 percent and 91 percent respectively for characterization of indeterminate adnexal lesions, the meta-analysis on pelvic magnetic resonance imaging (MRI) revealed higher summary malignancy rates for O-RADS MRI 4 and 5 lesions than predicted.

Employing an artificial intelligence (AI) tool to quantify airway-to-artery (AAR) diameter ratios on chest computed tomography (CT), researchers found the percentage of airways with an AAR greater than 1 was associated with increased pulmonary exacerbations in ever-smokers.

In an interview at the recent Radiological Society of North America (RSNA) conference, Alex Pozdnyakov, M.D. discussed findings from a new meta-analysis, which revealed that prostate-specific membrane antigen/positron emission tomography (PSMA PET) imaging in patients with prostate cancer recurrence led to treatment changes that resulted in a pooled 60.2 percent rate of prostate cancer-free survival at 20 months.

In a recent interview at the Radiological Society of North America (RSNA) conference, Eliot Siegel, M.D., discussed a variety of potential benefits with cloud-based image management in radiology, ranging from enhanced data security and economies of scale to improved access to a variety of artificial intelligence (AI) solutions to increase efficiency.

In a study of nearly 18,000 men who had prostate cancer screening, researchers found the use of pre-biopsy magnetic resonance imaging (MRI) for those with elevated prostate-specific antigen (PSA) levels and reserving MRI-targeted biopsy for those with PI-RADS scores of 3 to 5 reduced the risk of detecting clinically insignificant cancers by half.

Relief from looming reimbursement cuts, a PACS system that allows customized keyboard shortcuts and consistently relevant clinical histories are a few of the items on the wish list for this radiologist.

In a recent video interview from the Radiological Society of North America (RSNA) conference, Tessa Cook, MD, PhD discussed new research on automated de-identification in radiology reports and the potential of artificial intelligence (AI) and natural language processing (NLP) to help address time-consuming challenges in the radiology workflow.

In a new study based on five- to six-year follow-up data from over 650,000 children and young adults who had at least one computed tomography (CT) exam prior to the age of 22, researchers found a “strong dose-response relationship” between increased CT radiation exposure and brain cancer.
