Ultimate Guide to Digital Subtraction Angiography Equipment

You will get efficient and thoughtful service from Neusoft.

Digital Subtraction Angiography (DSA) is a pivotal imaging technique used primarily in vascular imaging, providing clear visuals of blood vessels by digitally subtracting non-vascular structures. This guide serves as a comprehensive resource on DSA equipment, focusing on various aspects such as technology, vendors, and key statistics to help you understand its implications in medical practice.

What is Digital Subtraction Angiography?

Digital Subtraction Angiography is an advanced technique that enhances the visibility of blood vessels by utilizing digital imaging. The process involves capturing two images: one before and one after the injection of a contrast agent. The first image, containing both the vascular and non-vascular structures, is then subtracted from the second image, leaving only the blood vessels visible.

Benefits of DSA Equipment

Modern DSA equipment offers several advantages:

• High Resolution: Ability to produce detailed images, aiding in accurate diagnosis.
• Real-Time Imaging: Instantaneous feedback allows for adjustments during the procedure.
• Lower Radiation Dose: Technological advancements have reduced the radiation exposure for patients and healthcare professionals.

Key Statistics in DSA

Understanding the landscape of DSA equipment can be informed by the following statistics:
