GE Ultrasound Feature
Compare Assistant
WorkflowCompare Assistant pulls a patient's prior ultrasound images from storage and presents them next to the live scan on the LOGIQ display. The clinician can compare specific regions of interest, overlay annotations from previous exams, and track changes between studies without leaving the scanning workflow. The system handles image retrieval automatically, eliminating the manual process of searching through archived studies on a separate PACS workstation. Compare Assistant is used in oncology follow-ups, thyroid nodule surveillance, and any clinical scenario where serial imaging comparisons inform treatment decisions. Available on GE LOGIQ systems.
Key Benefits
Why Compare Assistant matters
Automatic retrieval of prior studies during scanning
Compare Assistant pulls previous images without requiring the operator to exit the scanning workflow or access a separate PACS terminal. The prior study loads alongside the live scan, keeping the sonographer focused on image acquisition rather than system navigation.
Annotation overlay for precise region matching
Annotations and measurement markers from prior exams can be overlaid on the current study. This ensures the clinician is comparing the exact same anatomical location and measurement plane between visits, which is critical for accurate size trending.
1–3 minutes saved per follow-up exam on study retrieval
Manually searching for, loading, and positioning prior images alongside a current exam takes time that accumulates across a busy day. Compare Assistant eliminates this step, and for departments with 10+ follow-up studies daily, the time savings support higher throughput.
Supports structured surveillance protocols
Radiology departments following ACR TI-RADS for thyroid nodules or LI-RADS for liver lesions need consistent serial comparisons at defined intervals. Compare Assistant fits directly into these protocols by making prior study access immediate and integrated into the scanning workflow.
About Compare Assistant
Compare Assistant addresses a common workflow interruption in serial imaging: the need to leave the ultrasound interface to pull up prior studies from PACS or local storage. Instead, the system automatically identifies and retrieves the patient's most recent relevant exam and displays it alongside the current scan. Clinicians can scroll through prior images, overlay existing annotations, and place matched measurement calipers to quantify changes between exams. This is particularly valuable in radiology departments performing structured surveillance protocols, such as thyroid nodule monitoring based on ACR TI-RADS criteria or liver lesion follow-up using LI-RADS. The auto-retrieval function saves 1–3 minutes per exam that would otherwise be spent searching and loading prior studies. For departments performing 10+ follow-up exams per day, this adds up to meaningful workflow savings. Compare Assistant also supports multi-application use across vascular, abdominal, and musculoskeletal imaging where longitudinal comparison is part of the standard clinical workflow.
