Digital Subtraction Angiography Người thuyết trình: Trần Cao Thanh
What is a digital Subtraction angiography?
Dsa is a computerized x-ray technique in which the vascular anatomy; the vesels are visualized.
It is one of 4 angiography types : conventional angiography, DSA, CT, MRI.
DSA is used to detect blood cots, tumors and other blockage in blood vessels and other ducts

What are Materials of DSA?
Specialized X-ray Machine
Fluoroscopic screen
Contrast media/ Flourescien dye
Catheter
Guide wire
Contrast media: dye injected into the cirlularory system that when exposed to xrays.It make the the blood vessels and soft tissues are visualized.
How it is done?
During DSA, the the patien lie on a table and electrodes are placed on his/her chest to monitor heart health.
An xray image of the area is taken before the dye is injected.
A local anesthetic is injected into the skin at the side where the dye will be introduced
A thin tube is then insert in to the blood vessels and the dye is injected.
The computer subtracts structure in the first picture from the second picture, leaving only the blood vessels.

3D fusion Digital Subtraction Angiography f-DSA
A new x-ray technique conbine 3D reconstruction of the blood vessels.
It is where 3 D bone and 3D digital subtraction angiography are fused in a single 3D representation
The blood vessels are not clear enough?
3D rotational angiography
3DRA is an advance three dimensional xray technical made for a better diagnosis of smaller aneurysms that normal DSA cannot do
Interventional radiology
What is a interventional radiology?
Interventional radiologist make use imaging techniques for purpose percutaneous, diagnostic and therapeutic procedures.
Significant of interventional radiology.
Cancer treatment: istering cancer medications directly to the tumor site.
Needle biopsy
Diagnostic test for breast and lung cancer
Biopsy can provide a diagnostic test without intervention surgical.
commonIVR procedure coronary angioplasty
It opens a blocked or narrowed blood vessels, by insert a very small balloon in to the vessel and inflating it?
