methodsangiography
Methodsangiography is the field devoted to imaging techniques used to visualize blood vessels. It encompasses both invasive catheter-based procedures and noninvasive approaches, with the goal of mapping vascular anatomy, assessing blood flow, and identifying pathology such as aneurysms, stenoses, malformations, and occlusions.
Invasive angiography typically involves catheter insertion with contrast injection and fluoroscopic X-ray imaging. Digital subtraction angiography
Applications of methodsangiography span neurology, cardiology, and vascular surgery. They are used to diagnose intracranial aneurysms
Safety and limitations vary by method. Invasive angiography carries risks of bleeding, infection, arterial injury, and
Historically, angiographic techniques evolved from early catheter-based imaging to modern DSA, CTA, and MRA, expanding the
