Digital subtraction angiography (DSA) is a digital radiography, digital fluoroscopy, and photo electronic imaging techniques intended for the diagnosis and treatment of various vascular disorders. Digital subtraction angiography is subtraction of two images that are obtained before and after contrast media is administered into the patient for the purpose of angiography. The digital subtraction angiography (DSA) systems were introduced in the late 1970s to obtain clear images of arteries, veins and organs of the body using complex computerized X-ray equipment. Digital subtraction angiography also facilitates to detect abnormalities such as ulcerated plaques, extra-cranial occlusions, stenosis and aneurysms. In addition to its regular application in carotid arteries this technique is extensively used in the evaluation of vascular by-pass grafts, aortic arch anomalies and aortic coarctation. Recently developed three-dimensional DSA has been proved to be enhanced in the detection and delineation of intracranial aneurysms, with lower radiation dose, less contrast use, and shorter procedural time compared to two dimensional DSA.
Digital Subtraction Angiography Market: Drivers & Restraints
Global digital subtraction angiography market is estimated to show a healthy growth in the coming years due to increasing incidence of cardiovascular diseases. Major driver for the global subtraction angiography market are technological advancements, increasing number of launch of new products with lower iodine dose contrast medium, novel gadolinium contrast medium based, advanced noise reduction imagining technology based DSA products, etc. Moreover, increasing awareness of people for accurate and precise diagnosis is an additional factor which is anticipated to drive the global digital subtraction angiography market. However, relative infrequency of serious reactions to intravenously administered contrast material, price and reimbursement issues and stringent regulatory approvals are major factors that can hinder the global digital subtraction angiography market growth over the forecast period.
