listen to the pronunciation of angiography
Английский Язык - Английский Язык
A medical imaging technique in which an X-ray image is taken to visualize the inside of blood vessels and organs of the body, with particular interest in the arteries, veins and the heart chambers
This is a test performed to highlight the outlines of the heart and blood vessels to see if there are any blockages or malformations
an x-ray made of blood vessels after the introduction of a radioopaque substance called a Contrast Medium
Radiographic technique to visualize the internal anatomy of the heart and blood vessels after the injection of a contrast medium
Radiography of vessels after the injection of a radiopaque contrast material Unlike angioplasty, which is an invasive procedure, angiography breaks the skin only for the insertion of a needle for administering a radiopaque catheter and positioning under fluoroscopic control This technique is used to image arteries in the brain, heart, kidneys, gastrointestinal tract, aorta, neck, chest, limbs and pulmonary circuit
Angiography is utilized to image blood vessels Traditional angiographic techniques utilize direct injection of iodinated contrast into an artery and obtaining radiographs of the vessels of interest Newer angiographic techniques have been developed which are non-invasive MR Angiography utilizes special sequences to image blood vessels, and is especially helpful in analyzing brain and neck arteries Contrast may or may not be used, depending on the circumstances CT Angiography utilizes special reconstruction techniques following the intravenous administration of iodinated contrast Doppler duplex ultrasound may be utilized to evaluate arteries and veins This technique combines the standard ultrasongraphic imaging of a vessel in addition to determining the blood velocity to assess both the degree of narrowing and morphologic characteristics of the vessel No contrast is used in this technique
depiction of vessels using special pulse sequences, e g fast imaging sequences, see also MRA
is an imaging procedure that usually involves the insertion of a catheter into an artery and injection of a contrast (dye) material to see the outline of the artery and to identify narrowings and blockages Angiography can also be performed on "chambers" of the heart, such as the left ventricle, to see how well it is pumping
An X-ray examination of blood vessels, following injection of a contrast dye, to find blockages in the arteries of the heart Helps determine how much coronary artery disease is present
The imaging of veins and arteries [Chapter 12]
an imaging technique that provides a picture, called an angiogram, of blood vessels
The process of obtaining images of blood vessels within and under the retina that retinal surgeons use to determine how best to stop them from leaking
roentgenographic examination of blood vessels after injection of a radiopaque contrast medium; produces an angiogram
Radiographic visualisation of blood vessels
an x-ray that uses dye injected into the coronary arteries so that blood circulation can be studied
This procedure uses X-rays to produce pictures of arteries (Arteriogram) or veins (Venogram) by injecting a dye (contrast material) into the arteries or veins and 'filming' it as it passes through the blood vessels
a diagnostic test used to identify the exact location and severity of coronary artery disease During angiography a small tube or catheter is inserted into an artery and guided with the assistance of a fluoroscope (x-ray) to the opening of the coronary arteries which supply blood to the heart A dye, visible on x-rays, is then injected into each coronary artery to reveal the extent and severity of blockages Images produced by angiography are known as angiograms
Test used to examine blood vessels in the retina, choroid and iris of the eye See also Fluorescein Angiography
A test to determine the severity and location of blocked arteries of any part of the body, particularly the heart arteries
an x-ray examination of the blood vessels following the injection of contrast material; used as a diagnostic tool in conditions such as a heart attack or stroke The x-ray that is produced is called an angiogram
Angiography is done during a cardiac catheterization During a cardiac catheterization, a flexible tube is threaded from the groin up the aorta and into the heart During angiography, an opaque dye is injected into the left and right coronary arteries An x-ray camera is then aimed at the flow of blood in a certain area of a blood vessel and black and white movies of the channel of blood running through that segment of the artery is recorded Areas where fatty plaque is thick and slows blood flow to a trickle or totally obstructs it, are the areas where the heart is getting too little oxygen which causes chest pain (angina) Often a bypass graft is placed in these areas during coronary artery bypass grafting (CABG)surgery See angioplasty
an x-ray study that uses dye injected into arteries to study blood circulation
Radiography of blood vessels using the injection of material opaque to x-rays to give better definition to the vessels
An x-ray technique that makes use of a dye injected into the coronary arteries to study blood circulation through the vessels The test allows physicians to measure the degrees of obstruction to blood flow Circulation through an artery is not seriously reduced until the inside diameter of the vessel is more than 75% obstructed
an x-ray technique to visualise the lumen of an artery, using radio-opaque dye
an x-ray that uses dye injected into arteries so that blood circulation can be studied
A description of blood vessels and lymphatics
or arteriography X-ray examination of arteries and veins with a contrast medium to differentiate them from surrounding organs. The contrast medium is introduced through a catheter to show the blood vessels and the structures they supply, including organs. Angiography of diseased leg, brain, or heart arteries is necessary before corrective surgery. See also angiocardiography
