研究概览
简要总结
The purpose of this clinical study is to evaluate the CARESTREAM Vue PACS 12.1.5 Computed Tomography (CT) Perfusion ("investigational device") imaging performance. Evaluation of CT Perfusion (CTP) imaging will compare CTP with the predicate device, the Olea Sphere PACS with CT Perfusion Module.
详细描述
This study will demonstrate the imaging performance CTP by an assessment of 30 CTP de-identified patient cases collected retrospectively. The purpose of the study is to demonstrate equivalent clinical quality between the investigational and predicate devices using a radiologist evaluation of key metrics which are applicable to CTP images.
The maps include the following:
- Mean Transfer Time (MTT) - the time that the contrast material stays in the tissue
- Cerebral Blood Volume (CBV) - the volume of blood that is in a known volume of the tissue based on the concentration of contrast material that is in the tissue over the time
- Cerebral Blood Flow (CBF) - describes the flow of the blood to the affected tissue
- Time To Peak (TTP) - the time that maximum enhancement is achieved at each volume of the tissue
- Time to maximum of impulse response function (TMAX)
The retrospective data collected for each patient will include a non-contrast head CT exam completed on the same day as CTP image, and a follow-up head CT at least 1-2 days after the initial imaging study (initial non-contrast head CT) if available.
Similar performance between the investigational and predicate devices was demonstrated by the following criteria.
