	Angiography Test
		Angiography helps your physician determine the source of the problem and the extent of damage to the blood vessel segments that are being examined.
		During angiography, a long slender tube called a catheter is inserted into a large artery (generally, in the groin area).
		A physician specially trained in angiography studies the X-ray pictures to determine the source of the problem and the extent of damage to the blood vessel segments that are examined.

	Imaginis - Angiography
		X-ray angiography is performed to specifically image and diagnose diseases of the blood vessels of the body, including the brain and heart.
		Conventional x-ray angiography has a lead role in the detection, diagnosis and treatment of heart disease, heart attack, acute stroke and vascular disease which can lead to stroke.
		In modern angiography systems, each frame of the analog TV signal is then con verted to a digital frame and stored by a computer in memory and/or on hard magnetic disk.

	Connecticut Surgical Group - Education - Intereventional Radiology - Angiography
		Angiography is a diagnostic procedure to obtain x-ray images of your arteries and veins to define narrowing, blockages and other problems that may be interfering with the flow of blood through them.
		Developed as a technology in the 1960s, today angiography is applied to vascular problems throughout the body, including the carotid artery in the neck, the renal arteries serving the kidneys, the aorta in the abdomen and the blood vessels in the legs.
		Angiography yields an extremely accurate image of the condition of the blood vessels in question, and can lead to decisions as to whether to rely on medical therapy, plan surgical reconstruction of the vessels in question, or consider endovascular treatments such as angioplasty.

	Angiography \| DoctorNDTV: Health Information on Angiography
		Angiography is used to detect abnormalities or blockages in the blood vessels throughout the circulatory system and in some organs.
		In a coronary angiography, the arterial puncture is typically given in the femoral artery, and the cardiologist uses a guide wire and catheter to perform a contrast injection and x-ray series on the coronary arteries.
		Angiography patients are also advised two to three days of rest and relaxation after the procedure in order to avoid placing any undue stress on the arterial puncture site.

		Because of the lack of nephrotoxicity and allergic reactions, CO is increasingly used as a contrast agent for diagnostic angiography and vascular interventions in both the arterial and venous circulation.
		The gas is also used as a contrast agent for imaging of the nonvascular structures such as the bile duct, upper urinary tract, gastrointestinal tract, and peritoneal cavity.

		An angiography is an x-ray of the arteries.
		For a cerebral angiography, the contrast dye is injected into one or both of the carotid arteries in the neck.
		Digital subtraction angiography (DSI) uses a computer to "subtract" or take out the bones and tissues in the region viewed, so that only the blood vessels filled with the contrast dye are seen.

	Encyclopedia - Angiography
		Angiography is a diagnostic test used by ophthalmologists to photograph structures in the back of the eye and is especially useful in finding damage to the blood vessels, which nourish the retina.
		In both angiography procedures, a small amount of colored dye is injected into a vein in the arm where it travels through the circulatory system and into the vessels in the eye.
		The dye used in fluorescein angiography sometimes causes temporary, harmless discoloration of the skin and urine, and a small percentage of patients may feel slightly nauseated for a short time during the initial phase of the procedure.

	Patient Information Guide : Angiography
		Angiography is a type of x-ray that is done to image blood vessels in various parts of the body, including the heart, brain, and kidneys, so as to determine whether the vessels are diseased, narrowed, enlarged or blocked altogether.
		Catheter angiography still is widely used in patients who may undergo surgery, angioplasty, or stent placement.
		Common reasons to do catheter angiography are to detect narrowing or blockage of a blood vessel, identify abnormally dilated blood vessels, and determine the site of internal bleeding.

		An angiography is a technique that produces a picture of the inside structure of blood vessels and/or the heart by using radiation (a type of energy) known as X-rays or gamma rays.
		Other conditions that angiographies are used to diagnose are heart attacks, stroke (a burst artery or a blockage of an artery in the brain), kidney tumors, narrowing of the renal artery (a pair of arteries in the kidneys), and increased blood pressure in the portal vein.
		A special type of angiography that does not use a catheter and does not require the use of contrast is known as a magnetic resonance angiography.

	5) Diagnosis: Angiography
		Angiography of the celiac and mesenteric vessels is performed before proceeding with curative surgery for pancreatic cancer.The Whipple Procedure may be performed only when the cancer is confined to the pancreas and locoregional tissues that are routinely removed during the procedure.
		If the angiography reveals that the cancer has spread to the blood and possibly other organs via the blood vessels, a Whipple procedure will not be performed.
		This procedure is gradually being replaced by CT angiography or MR angiography which allow imaging of the blood vessels surrounding the pancreas without the need to place an catheter directly into an artery.

		Cerebral angiography is an invasive test that involves the injection of contrast media into the carotid artery by means of a catheter.
		Angiography may be utilized to identify bleeding aneurysms, vasospasm, and areriovenous malformations, and to differentiate embolism from large artery thrombosis [Adams HP, et al, 1994.
		Presently, angiography is performed mainly in selected patients, especially those in whom surgery (such as carotid endarterectomy or craniotomy for ruptured aneurysms or arteriovenous malformations) is considered.

	eMedicine - Pulmonary Angiography : Article by Hearns W Charles, MD
		Although pulmonary angiography has morbidity (2-5%) and mortality (0.2%) rates lower than those of empiric anticoagulation (5-25% and 1-2%, respectively), it has not gained widespread acceptance, and it is not universally available (Kelley, 1991; Cheely, 1981; Stein, 1992).
		A PE is diagnosed by using angiography with visualization of the endoluminal filling defects, thromboemboli, or abrupt vascular obstruction.
		Dynamic anatomic detail is provided by conventional angiography, in which the angiographic run, similar to that of cineangiography, provides anatomic landmarks for targeting the embolization (see Images 7-9).

	EB Angiography, EBT & CT Angiography - Get Your Calcium Score
		While catheter angiography is still considered the gold standard for diagnosis of arterial disease and is necessary for intervention (stent, balloon, etc), it does require hospitalization, entry of an artery and post-procedural recovery.
		Although CT Angiography does not always replace invasive coronary angiography, patients and their physicians will have a better understanding of what type of intervention might be required at the time of hospitalization.
		For many patients, CT angiography may eliminate the need for invasive coronary angiography and together with a calcium score is the most highly predictive of patient outcomes.
