We used image subtraction to analyze the findings of ICG angiography in choroidal neovascularization associated with age related macular degeneration. This method was useful in clear determination of the extent and location of CNV and in evaluating the degree and exact location of ICG leakage.

D015901 Angiography, Digital Subtraction A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues. Digital Subtraction Angiography,Subtraction Angiography, Digital
