GE HealthCare reinforces leadership in AI with Lung Guidance and AutoAS on Vscan Air for point of care ultrasound assessments
New AI-assisted capabilities expand the
Patients presenting with symptoms such as shortness of breath can require clinicians to consider cardiac, pulmonary or overlapping causes, often in time-pressured settings where formal imaging or specialist interpretation may not be immediately available.
“Clinicians at the point of care are often working with limited time and incomplete information, and a symptom like shortness of breath rarely announces if it’s coming from the heart, the lungs, or both,” said
Supporting more consistent lung ultrasound acquisition
Lung Guidance provides real-time scan guidance to help clinicians optimize probe position and acquire diagnostic-quality lung images by guiding them to correct anatomical landmarks in each zone of the standard 8-zone lung protocol. The system helps guide image acquisition through the detection of lung landmarks including the pleural line, A-lines, rib shadows, diaphragm and abdomen.
When predefined landmark and image-quality criteria are met, AutoCapture automatically records an ultrasound clip. A Save Best Clip feature also allows users to retain the best quality image from each view during scanning when AutoCapture conditions are not achieved. Lung Guidance additionally supports B-line detection and scoring, as well as reporting to help clinicians organize findings from the acquired lung ultrasound exam.
In validation testing, Lung Guidance enabled non-expert lung ultrasound users to consistently acquire diagnostic-quality lung ultrasound exams, with 95.2 percent success compared with 96.8 percent for expert users, per a descriptive assessment.2
AI-assisted aid for assessing moderate/severe aortic stenosis
AutoAS is designed to provide an AI-assisted automated visual estimate of the presence or absence of moderate-to-severe AS using standard 2D cardiac images acquired with Vscan Air SL. With at least two compatible standard echocardiographic views—parasternal long-axis (PLAX), parasternal short-axis at the aortic valve (PSAX-AV) or apical five-chamber (AP5)—AutoAS analyzes the images and provides an estimate indicating whether findings are suggestive of moderate-to-severe AS, along with a confidence score indicating the algorithm’s certainty.
AutoAS is designed to support a clinician’s early assessment of AS when access to formal echocardiography may be delayed.3 AutoAS was trained and validated against a reference panel of expert cardiologists and can reduce the variability of missed AS compared to visual interpretation alone.4
Together, Lung Guidance and AutoAS build on Vscan Air’s existing AI capabilities, including Caption AI and Auto Bladder Volume, and reflect GE HealthCare’s efforts to support the confident use of ultrasound by more users.
