2025年1月21日 · Digital subtraction angiography (DSA) is a fluoroscopic technique used extensively in interventional radiology for visualization of blood vessels. Radiopaque structures such as bones are digitally eliminated ("subtracted") from the image, thus allowing for an accurate depiction of the blood vessels.

Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment.

Digital Subtraction Angiography (DSA) Provides an image of the blood vessels in the brain to detect a problem with blood flow. The procedure involves inserting a catheter (a small, thin tube) into an artery in the leg and passing it up to the blood vessels in the brain.

Digital subtraction angiography (DSA) is an imaging technique used to diagnose and confirm abnormal lesions of cerebral blood vessels in various situations. Several complications such as cerebral infarction, contrast-induced allergy, and angio-site …

Digital subtraction angiography allows for direct visualization of the cerebral vasculature and remains the gold standard for detecting aneurysms. This diagnostic tool requires a dedicated neurointerventional team and provides an opportunity for therapeutic interventions as …

Digital subtraction angiography (DSA) is a new radiographic technology used in diagnosing vas- cular disease. DSA is employed to obtain images of arteries in various parts of the body and is highly effective in contrasting arterial structures with their surrounding bone and soft tissue (3).

Objective: To assess the blood flow of the proper digital artery using digital subtraction angiography (DSA) in the early stage after replantation. Methods: From January 2006 to October 2010, 27 anastomosed arteries in 27 replanted digits were included in the study.

As experience with digital subtraction angiography (DSA) increases, both its advantages and disadvantages have become more evident. Although the intravenous approach (IV-DSA) is safer and less expensive than conventional arteriography, images are frequently suboptimal.

This review will describe the principles involved in digital subtraction angiography and explore some of the clinical applications for this technology in peripheral vascular and cardiac diagnosis.

Digital Subtraction Angiography (DSA) is the gold-standard imaging modality in acute cerebrovascular diagnosis. The role of DSA has become increasingly prominent since the incorporation of endovascular therapy in standards of care for acute ischemic stroke.
