We have a long-standing interest and relatively high-volume practice directed at the diagnosis and treatment of spinal dural arteriovenous fistulas (SDAVFs). Patients with an SDAVF frequently have been misdiagnosed or have not been diagnosed at the time of their initial presentation at our institution. The ability to diagnose the patient’s SDAVF … more »

C-Arm Measurement of Cerebral Blood Volume and Cerebral Blood Flow Using a Novel High-Speed Acquisition and a Single Intravenous Contrast Injection

Kevin L. Royalty

The flat detector technology that is now available in the angiography suite on most commercial C-arm systems provides a platform for both CT and angiographic imaging, and with it, the potential for high spatial resolution anatomic and physiologic imaging for intraprocedural diagnosis and evaluation.

“Time is Brain” has now become the mantra for … more »

Endovascular treatment of ischemic stroke has developed rapidly in recent years. I performed my first mechanical stroke treatment with a dedicated stroke device in a patient included in the penumbra trial that was published in AJNR in 2008. This patient showed a dramatic improvement of his clinical condition right after recanalization of the … more »

Flat panel detector (FPD) angiographic systems have been widely introduced into neurointerventional suites. They primarily allow the acquisition of high-quality 3D rotational angiography, but also allow us to obtain CT-like cross-sectional soft tissue imaging with different reconstruction modalities. FPD technology has been shown to permit fast imaging without the need for time-consuming patient … more »
