GE's AngioViz Approved by FDA
New product uses parametric imaging to give more infomation than DSA alone
GE Healthcare has recieved FDA clearance of AngioViz, an application that gives doctors a new visualization of vascular flow on a single image, helpful during complex interventional radiology procedures.
AngioViz provides a new visualization of the vascular flow seen in Digital Subtraction Angiography (DSA) imaging utilizing a technique called parametric imaging. AngioViz looks at each pixel in the image series and determines two things-the peak value of opacification caused by the contrast, and the time it takes for that pixel to reach peak opacification. These two parameters can be displayed as separate images or combined into a single color-coded image that represents parameters of vascular flow. This enables doctors to perceive parameters of flow quickly to support decision-making. In addition, AngioViz allows easy comparison of parametric images from different DSA acquisitions, such as pre- and post-treatment images. This can help physicians understand the impact on flow dynamics of various interventional treatments.
AngioViz bold flow visualization has the potential to be applied to a variety of clinical situations
· Help see where a blocked artery diminishes blood flow in the brain or other tissue
· Identify the timing and amount of blood flow in abnormal vessel anatomy
· Observe flow in abnormal tissue before and after treatment to support interventional oncology treatment
· Visualize peripheral artery blood flow before and after balloon angioplasty and stenting
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.
