Flat Panel Detector CT, CT Angiography, and CT Perfusion in Stroke

Flat panel detector CT, CT angiography, and CT perfusion in stroke.

Acute stroke imaging: CT with CT angiography and CT perfusion before management decisions.

Certainty of stroke diagnosis: incremental benefit with CT perfusion over noncontrast CT and CT angiography.

PURPOSE To systematically evaluate the diagnostic benefits and inter- and intraobserver reliability of an incremental computed tomographic (CT) protocol in the confirmation of clinically suspected stroke, with combined imaging and clinical data as the reference standard. MATERIALS AND METHODS Institutional review board approval was obtained, and participants gave informed consent. A total of ...

Three-dimensional imaging and cone beam volume CT in C-arm angiography with flat panel detector.

We evaluated a new 3D angiography system with a flat panel detector (FPD) for its capabilitiy to acquire volume sets during a single rotation scan and to reconstruct high spatial resolution three-dimensional and cross sectional images, namely cone beam volume computed tomography (CBVCT) images. Present status of the technique, advantages and potential applications are discussed.

Transcranial access using fluoroscopic flat panel detector CT navigation.

FPCT and navigation software on contemporary fluoroscopic units perform imaging of a quality comparable with conventional CT. They can accurately guide percutaneous procedures, providing live instrument visualization and the capability to re-image without patient transfer. FPCT navigation was used in the placement of a ventricular drain in a 62-year-old woman for subarachnoid-related hydrocepha...
