Minimum blood vessel diameter measured by magnification angiography

Visibility of small blood vessels was improved by magnification angiography of biologic specimens. Blood vessel diameter was determined for increasing magnifications by various screen-film combination. Significantly smaller vessels were recognized with the magnification technique in all screen combinations. Noisy screen-film combinations with better square wave transfer functions did not allow visualization of blood vessels as small as those screen-film combinations with poorer square wave transfer functions but less noise.
