Beyond Static CTA，Unlocking Time-Resolved Insight for Confident Diagnosis

In clinical practice, static CTA is often constrained by its single-phase acquisition—making it difficult to differentiate true vascular occlusion from delayed contrast filling. This can result in overestimation of clot burden and misinformed treatment decisions. Additionally, the ability to accurately evaluate intracranial collateral circulation remains limited, particularly in acute ischemic stroke, where it plays a critical role in guiding prognosis and intervention strategies.
uOmnispace.CT™ Dynamic Analysis enables comprehensive evaluation of time-resolved CT images, providing detailed visualization of vascular enhancement across multiple phases. It is particularly valuable for assessing intracranial collateral circulation, detecting vessel occlusions that standard CTA may overlook, aiding in moyamoya disease classification, and distinguishing arterial supply from venous drainage in arteriovenous malformations.

Dynamic Insight

Dynamic Analysis provides intuitive and time-resolved visualization of collateral circulation by combining 4D cine display with multiplanar reformation (MPR). It enables clinicians to trace contrast flow over time and across multiple planes, making it easier to detect delayed enhancement, retrograde filling, and collateral pathways. Vessel enhancement in regions of interest (ROI) can be assessed through time-density curves (TDC), which support quantitative analysis of perfusion dynamics and help identify cerebral artery occlusion.

Supports Digital Subtraction Angiography (DSA) mode to enable intuitive observation of cerebral blood flow by removing background structures and enhancing the visibility of vascular contrast dynamics. It provides high temporal resolution and delivers dynamic blood flow information without increasing patient burden. This makes CT DSA particularly valuable in time-critical scenarios such as acute stroke, where rapid evaluation of vascular status is essential.

In addition to neurovascular imaging, Dynamic Analysis supports body vessel visualization and joint motion assessment. It enables time-resolved viewing of contrast dynamics—for example, evaluating blood supply to liver or kidney tumors across phases, or observing functional joint motion such as temporomandibular movement—offering valuable insights for both diagnosis and treatment planning.

Streamlined Workflow

Automatic pre-processing runs background algorithms before the application launches, handling key steps like bone removal and table removal ,motion correction and artery-vein separation in advance. Upon entry, tasks such as motion correction, anatomical segmentation, and vessel delineation can also be completed automatically—reducing manual steps and streamlining workflow.

Dynamic CT reconstruction supports fast saving of results to streamline diagnosis. Cine images can be exported as video files for quick review, while dynamic datasets can be saved as multi-phase VR or MIP in DICOM format. Saved results are viewable in Review 2D and can be sent directly to PACS for efficient integration into clinical workflows.
