What are the different types of vascular display?
The use of various imaging technologies to visualize blood vessels for diagnosis and medical procedures is referred to as vascular imaging. Since the first artery image was perceived in 1929 using X -ray technology, science has improved drastically in the field of technology and has developed ways to capture three -dimensional (3D) and vascular images in real time. Today, there are basically four types of vascular imaging used with medical devices: arteriogram, ultrasonic, magnetic resonance imaging (MR) angiography and angiography of computer tomography (CT). Each has clear advantages and disadvantages and therefore specialize in different procedures.
The arteriogram uses X -ray technology and a contrasting dye injected into the artery to obtain visible images. This procedure provides high -level arteries for comparative size and location if necessary. Data can also be stored as a digital file, so it is portable and convenient for an arc whatIt is a big reason why this type of vascular display has become so popular in limited use. The exposure of radiation remains the main disadvantage of this vascular display technique.
instead of radiation uses ultrasonic equipment of sound waves, making it a much safer procedure for patients and healthcare workers. In addition to real -time viewing benefits, it also captures the speed and direction of blood flow in arteries and veins, as well as pumping and pulsating blood vessels. Ultrasound has gained popularity because it is portable, cheaper than other methods and offers less total discomfort to patients. However, its disadvantage within the category of vascular imaging is that the procedure is strongly dependent on the operator, which means that the device can only use trained experts effectively.
as well as ultrasound, Mr. angiography is not an X -ray procedure; Instead uses magnetic waves to youCreating a picture of the patient's anatomy. The advantage of this modality over other methods is that, due to its time resolution, Mr. angiography can be purchased several 3-D data images, which allows a more accurate study of a particular area of interest during time run. Unfortunately, this procedure is dangerous for patients with pacemaker and/or surgical clips. Angiography MR is also more difficult to perform compared to other types of vascular display.
On the other hand, CT angiography offers simplistic operation while taking up up to 64-cuts for 20 to 30 seconds with high-resolution images. For this reason, CT scanners are now common in emergency rooms where speed and resolution are decisive in the diagnosis of several traumatic cases. The unique advantage of CT angiography over other vascular imaging technologies is its capacity to capture 3-time images of flowing blood throughout the vascular system in one perspective. Tos disadvantage, as with the arteriogram, isIt uses the use of radiation and the danger of long -term exposure.
