Intended Use

Stroke VCAR is a CT image analysis software package that provides information to physicians to assist them in the analysis and visualization of Brain CT data derived from DICOM 3.0 compliant CT scans. Stroke VCAR is designed for the purpose of segmenting and assessing intracerebral and intracranial hemorrhages in the brain using semi-automated tools on non-contrast CT exams. Additionally Stroke VCAR provides a set of workflow tools for the segmentation and visualization of aneurysms in the brain from contrast enhanced CT exams. It is intended for use by clinicians to process, review, archive, print and distribute CT studies. This software will assist the user by providing initial 3D segmentation, measurements and visualization of hemorrhages and aneurysm in the brain. The user has the ability to adjust, review and has to confirm the final segmentation.

Device Story

Stroke VCAR is a CT image analysis software package; inputs DICOM 3.0 compliant CT scans. Device uses semi-automated tools to perform 3D segmentation, measurement, and visualization of intracerebral/intracranial hemorrhages and brain aneurysms. Clinicians operate the software to process, review, archive, print, and distribute studies. The user must adjust, review, and confirm final segmentations. Output provides physicians with clinically relevant information for diagnosis, treatment planning, and follow-up. Device aims to improve workflow efficiency and diagnostic value in stroke work-ups.

Clinical Evidence

Clinical evaluation study conducted with three CT technologists and three board-certified neuroradiologists. Assessed productivity of automated vs. manual hematoma segmentation and qualitative user feedback. Results demonstrated significantly reduced workflow time for automated hematoma segmentation compared to manual methods. Study concluded the device adds diagnostic value to hematoma and aneurysm clinical workflows.

Technological Characteristics

Software-based CT image analysis tool. Complies with NEMA PS 3.1-3.20 (2011) DICOM standards. Features semi-automated segmentation tools including thresholding and auto-select. Operates on DICOM 3.0 compliant CT data. Software level of concern: Moderate.

Indications for Use

Indicated for clinicians to assist in analysis and visualization of Brain CT data (DICOM 3.0) for segmenting/assessing intracerebral and intracranial hemorrhages (non-contrast CT) and aneurysms (contrast-enhanced CT).

| Device Description /<br>Intended Use: | Stroke VCAR is intended to provide 2D and 3D processing,<br>review and analysis of CT images originally acquired to evaluate<br>the cerebral vascular system and/or intracranial bleeding. The<br>combination of the acquired images, reconstructed images,<br>and measurements performed by the clinician using Stroke<br>VCAR are intended to provide the referring physician clinically<br>relevant information for the purpose of diagnosis, treatment<br>planning and follow-up. |
| Indications for Use: | Stroke VCAR is a CT image analysis software package that<br>provides information to physicians to assist them in the analysis<br>and visualization of Brain CT data derived from DICOM 3.0<br>compliant CT scans. Stroke VCAR is designed for the purpose of<br>segmenting and assessing intracerebral and intracranial<br>hemorrhages in the brain using semi-automated tools on non-<br>contrast CT exams. Additionally Stroke VCAR provides a set of<br>workflow tools for the segmentation and visualization of<br>aneurysms in the brain from contrast enhanced CT exams. It is<br>intended for use by clinicians to process, review, archive, print<br>and distribute CT studies.<br>This software will assist the user by providing initial 3D segmentation, measurements and visualization of hemorrhages and aneurysm in the brain. The user has the ability to adjust, review and has to confirm the final segmentation. |
| Technology: | The Stroke VCAR software employs the same fundamental<br>scientific technology as its predicate device. |
| Determination of<br>Substantial Equivalence: | Summary of Non-Clinical Tests:<br>The Stroke VCAR software complies with NEMA PS 3.1 - 3.20<br>(2011) Digital Imaging and Communications in Medicine (DICOM)<br>Set (Radiology) standard.<br>The Stroke VCAR software employs the same fundamental<br>scientific technology as its predicate device (Volume Viewer).<br>Stroke VCAR SW uses the equivalent CT DICOM image data<br>input requirements. It has equivalent display, formatting,<br>archiving and visualization technologies compared to the<br>predicate device. Stroke VCAR utilizes the enhanced<br>segmentation tools (threshold, auto-select) already found in<br>Volume Viewer and optimizes the segmentation algorithms for Hematoma segmentation and Aneurysm segmentation.<br>Thorough testing of these capabilities has not raised any safety or effectiveness issues.<br>The following quality assurance measures were applied to the development of the system:<br>Risk Analysis Requirements Reviews Design Reviews Integration testing (System verification) Performance testing (Bench testing, validation) Safety testing (Verification) |
| | Summary of Clinical tests: |
| | A clinical evaluation study using consented clinical images was<br>conducted by three CT technologists in Part 1 and three board<br>certified neuroradiologists in Part 2a and Part 2b who were<br>considered experts. The study was meant to assess the<br>following: |
| | ■ Productivity benefits of automated vs. manual hematoma<br>segmentation (Part 1)<br>■ General user Qualitative feedbacks of the Stroke VCAR<br>edition tools (Part 2a and Part 2b) |
| | The study results demonstrated that the workflow time to<br>perform automated hematoma segmentation utilizing the<br>Stroke VCAR hematoma edition tool was significantly less than<br>the workflow time to perform hematoma segmentation<br>manually. |
| | Additionally study results clearly show that Stroke VCAR adds<br>diagnostic value to the current hematoma and aneurysm<br>clinical workflow and is a useful tool for neuroradiologists to<br>providing comprehensive stroke work-up including automated<br>hematoma and aneurysm processing and analysis,<br>quantification and monitoring. |
| | The substantial equivalence determination is based on the<br>software documentation for a MODERATE level of concern<br>device. |
| Conclusion: | GE Healthcare considers the Stroke VCAR software application<br>to be as safe, as effective, and performance is substantially<br>equivalent to the predicate device. |
