US identifies patients at higher stroke risk
Using transcranial Doppler ultrasound to detect asymptomatic cerebral emboli can identify patients who are at a higher risk of stroke and transient ischemic attack as well as those with a low absolute stroke risk, according to an international study.
Using transcranial Doppler ultrasound to detect asymptomatic cerebral emboli can identify patients who are at a higher risk of stroke and transient ischemic attack as well as those with a low absolute stroke risk, according to an international study.
The technique might also be useful in selecting patients with asymptomatic carotid stenosis who are likely to benefit from endarterectomy.
Embolic signs-short-duration, high-energy signals-were present in 77 of 467 patients at baseline. The hazard ratio for the risk of ipsilateral stroke and transient ischemic attack from baseline to two years in patients with embolic signals compared with those without was 2.54. The hazard ratio for ipsilateral stroke alone was 5.57 (Lancet DOI:10.1016/S1474-4422(10)70120-4).
Absolute annual risk of ipsilateral stroke or a transient ischemic attack between baseline and two years was 7.13% in patients with embolic signals and 3.04% in those without. The absolute annual risk of ipsilateral stroke alone was 3.62% in patients with embolic signals and 0.7% in those without.
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.
