What is DSA (Digital Subtraction Angiography) Head

Do you Hermina Friends, the term “Brain Washing” has recently become an interesting discussion not only among the general public but also among medical professionals.

In the medical field, what is meant by “Brain Washing” is actually DSA (Digital Substraction Angiography), a procedure performed on the human brain. So, the term "Brain Washing" is actually not quite right when used in the medical field. The term "Brain Washing" is only generally used in the world of espionage, meaning a condition where a hostage or detainee is given a doctrine that he wants to "stuff" into his mind.

At the beginning of its development, conventional Digital Subtraction Angiography (DSA) was a procedure performed to take an image of the structure of the blood vessels of the brain by spraying a contrast agent (iodine) so that it could be detected by an X-ray device and printed on film. Contrast fluid is sprayed through the neck vessels as the closest access, and the films used are in layers.

As technology and computerized digital systems develop, DSA can now detect abnormalities in blood vessels more clearly and measurably, and uses as little contrast fluid as possible. Using a catheter (a small tube with a diameter smaller than 2 mm) through a vein in the leg (femoral) also provides a more comfortable experience.
