VIDEO AND DIGITAL FLUORESCEIN ANGIOGRAPHY

[Simultaneous digital indocyanine green and fluorescein angiography].

BACKGROUND The simultaneous recording of indocyanine green and fluorescein angiography is since more than twenty years possible. The real-time digital recording of angiograms is about since 10 years possible. Because of the poor temporal resolution due to technical limitations, both of the above methods were only seldom used routinely. Graphics workstations can digitize and store multiple video...

Fundus photography and fluorescein angiography Fluorescein angiography

Fluorescein angiography is a clinical diagnostic test procedure in which rapid-sequence photography is performed after intravenous injection of sodium fluorescein. The procedure allows the documentation of the retinal circulation. Of equal importance is the ability of the angiogram to outline the entire retinal vascular bed. Previous clinical methods of examination of the fundus enabled the phy...

Cine photography and video recording of anterior segment fluorescein angiography.

A description is given of apparatus and technique for carrying out cine photography and video recording of anterior segment fluorescein angiography. We found cine best for single-frame analysis and video tape recording less expensive.

Intravenous angiography using digital video subtraction: intravenous cervicocerebrovascular angiography.

The clinical application of intravenous angiography to study the cervicocerebrovascular system using the digital video subtraction system described in a companion article is reported. About 0.75 ml/kg of a standard 76% iodine contrast solution is injected into an antecubital vein using a power injector. Then 15-20 exposures of the head and neck region at a 1/sec rate are made on the image inten...
