The addition of density heterogeneity on CT to a predictive model for differentiating malignant and benign pulmonary nodules led to a greater than 15 percent improvement in the model’s AUC, according to a new multicenter study.

Researchers estimated that 17.9 million middle-aged women in the United States are overdue for breast, cervical or colorectal cancer screening, according to a new cross-sectional study.

In a new capabilities analysis of 16 CE-marked AI software platforms for CT lung cancer screening, researchers found that only 6.7 percent of supporting peer-reviewed studies were prospective and that none of the studies assessed impact on patient outcomes.

While previous research has demonstrated the capability of the PET/CT agent (89Zr)girentuximab for detecting clear cell renal cell carcinoma (ccRCC), a new analysis reveals a 98 percent positive predictive value (PPV) for detecting non-ccRCC renal cancers.

In an independent test set, a radiomic AI model demonstrated an 82 percent AUC for detecting pancreatic ductal adenocarcinoma on computed tomography (CT) scans at a median of nearly 16 months prior to clinical diagnosis.

The CT-based True Definition DL software reportedly facilitates enhanced efficiency and high-resolution visualization for musculoskeletal, pulmonary and inner ear imaging.

For people with a history of heavy smoking, detection of significant incidental findings (SIFs) on low-dose computed tomography (LDCT) screening scans was associated with a 13.89 per 1000 marginal risk difference for extrapulmonary cancer in contrast to those with no SIFs, according to a study involving over 26,000 people.

The Photonova Spectra photon-counting CT system reportedly offers a variety of features, including 8-bin energy resolution, rapid rotation speed and motion-free imaging.

While smokers with negative baseline CT findings had a higher overall lung cancer risk than never smokers, the authors of a new study of over 30,000 people noted no elevated risk at two years.

More prominent honeycombing, reduced total ground glass opacity (GGO) and less pure GGO on CT scans each demonstrated 75 percent or higher AUCs for differentiating usual interstitial pneumonia (UIP) from non-UIP, according to new research.

Providing 3D ultrasound tomographic views, the Breast Acoustic CT device has an updated configuration that reportedly improves coverage and visualization of posterior breast tissue.

Iodine density measurements with photon-counting detector CT offered higher than 93 percent sensitivity and 95 percent specificity for differentiating between bland and neoplastic portal vein thrombosis in newly published research.

Combining an 85 cm bore, high resolution and accelerated image reconstruction, the Rembra CT platform can reportedly handle up to 270 CT exams a day.

New research revealed that a “quadruple-low” radiation doing protocol with photon-counting CT provided significantly higher image quality and reduced contrast-induced nephropathy in comparison to energy-integrating detector CT (EID CT) for patients with lung cancer.

For the detection of lung cancer on low-dose CT, the eyonis LCS software reportedly offers greater than 90 percent sensitivity, specificity and negative predictive value (NPV).
