Chest CTA/leg CT combo affords better PE detection
A multicenter study funded by the National Heart, Lung, and Blood Institute says that combining a CT scan of the legs with chest CT angiography increases the chances of detecting pulmonary embolism.
A multicenter study funded by the National Heart, Lung, and Blood Institute says that combining a CT scan of the legs with chest CT angiography increases the chances of detecting pulmonary embolism.
Researchers from eight clinical centers compared three ways to diagnose blood clots in 824 patients suspected of having PE: chest CT angiography alone, chest CTA with venous-phase imaging (leg CT), and chest CTA with an objective clinical assessment known as the Wells Score. The combined chest CTA and leg CT approach provided PE detection and specificity rates of 90% and 95%, respectively. A high clinical probability combined with positive chest CTA correctly indicated PE in 96% of participants. However, a negative chest CTA on these patients did not confidently rule out PE.
The study appeared in the June 1 issue of the New England Journal of Medicine.
Study Reaffirms Low Risk for csPCa with Biopsy Omission After Negative Prostate MRI
December 19th 2024In a new study involving nearly 600 biopsy-naïve men, researchers found that only 4 percent of those with negative prostate MRI had clinically significant prostate cancer after three years of active monitoring.
Study Examines Impact of Deep Learning on Fast MRI Protocols for Knee Pain
December 17th 2024Ten-minute and five-minute knee MRI exams with compressed sequences facilitated by deep learning offered nearly equivalent sensitivity and specificity as an 18-minute conventional MRI knee exam, according to research presented recently at the RSNA conference.
Can Radiomics Bolster Low-Dose CT Prognostic Assessment for High-Risk Lung Adenocarcinoma?
December 16th 2024A CT-based radiomic model offered over 10 percent higher specificity and positive predictive value for high-risk lung adenocarcinoma in comparison to a radiographic model, according to external validation testing in a recent study.
