Digital Image receptors use?
CHARGE COUPLED DEVICES
acquisition of digital fluoroscopic images combined with injection of contrast material and real-time subtraction of pre- and post-contrast images to perform angiography is referred to as digital subtraction angiography
dsa
DSA stands for
dIGITAL SUBTRACTION ANGIOGRAPHY
medterm for bloodvessel
ANGIO
radiological study of blood vessel in the body after the introduction of iodinated contrast media.
ANGIOGRAPHY
It is simply a technique by which bone structures images are canceled out from a film of bones plus opacified vessels, leaving an unobscured image of the vessels.
SUBTRACTION
developed the technique of contrast x-ray cerebral angiography to diagnose diseases, such as tumors and arteriovenous malformations
EGAS MONIZ
when did EGAS MONIZ developed his technique
1927
when did egas moniz win his nobel prize
1949
who produced subtracted images using plain films.
ZIEDSES DES PLANTES
when was the idea of subtraction images were first proposed
1935
year of introduction of the Seldinger technique
1953
the procedure became safer as no sharp devices need to remain inside the vascular lumen
