The overarching objective of our proposal is to develop a One-Stop-Shop imaging using the available C-arm Cone-Beam Computed Tomography (CBCT) data acquisition systems currently widely available worldwide in interventional angiography suites to enable acute ischemic stroke patients to be imaged, triaged, treated, and assessed using a single modality in one room.
This is an evaluation to determine the efficacy of the use of C-arm CBCT with SMART RECON novel software for the rapid assessment of time-resolved CTA and CT perfusion in the setting of ischemic cerebrovascular events. As a leading center for the treatment of cerebrovascular disease in the Midwest as well as being one of the first Comprehensive Stroke Centers in the United States we have a large potential patient group to assess. Our pilot plan is to compare conventional CT/CTA/CTP acquired during the clinical work up with C-arm CBCT/CTA/CTP acquired in the angiography suite at initiation of therapy. The C-arm CBCT acquisition provides whole brain coverage (compared to only 8 cm brain coverage with conventional CT) with less radiation and higher resolution; the CT perfusion maps obtained using C-arm CBCT and new reconstruction algorithms provides better perfusion maps.

To assess the accuracy of three cone beam computed tomography (CBCT) systems in misfit detection at the implant-abutment joint.
Computed tomography modalities which use a cone or pyramid-shaped beam of radiation.
Modality of computed tomography in which the patient is irradiated in a spiral path around the body with a cone or pyramid-shaped beam.
Computed tomography where there is continuous X-ray exposure to the patient while being transported in a spiral or helical pattern through the beam of irradiation. This provides improved three-dimensional contrast and spatial resolution compared to conventional computed tomography, where data is obtained and computed from individual sequential exposures.
An imaging technique using a device which combines TOMOGRAPHY, EMISSION-COMPUTED, SINGLE-PHOTON and TOMOGRAPHY, X-RAY COMPUTED in the same session.
Tomography using x-ray transmission and a computer algorithm to reconstruct the image.

Radiology is the branch of medicine that studies imaging of the body; X-ray (basic, angiography, barium swallows), ultrasound, MRI, CT and PET. These imaging techniques can be used to diagnose, but also to treat a range of conditions, by allowing visuali...
Stroke - Cerebrovascular Disease (CVA)
A stroke is a serious medical condition that occurs when the blood supply to part of the brain is cut off. Strokes are a medical emergency and prompt treatment is essential because the sooner a person receives treatment for a stroke, the less damage is ...
