Magnetic Resonance Angiography (MRA) Magnetic resonance angiography – also called a magnetic resonance angiogram or MRA – is a type of MRI that looks specifically at the body’s blood vessels. Unlike a traditional angiogram, which requires inserting a catheter into the body, magnetic resonance angiography is a far less invasive and less painful procedure.

- An angiogram is an X-ray image of blood vessels after they are filled with a contrast material. An angiogram of the heart, a coronary angiogram, is the gold standard for the evaluation of coronary artery disease (CAD).A coronary angiogram can be used to identify the exact location and severity of CAD.n angiogram of the heart, a coronary angiogram, is the gold standard for the evaluation of coronary artery disease (CAD).

- The use of angiography as a purely diagnostic radiologic treatment has steadily declined since the 1980s. However, during the same period, the therapeutic applications of angiography have expanded considerably. Angiography provides a complete examination of the arterial supply to an organ. For studies of the kidney, the aorta and renal arteries are typically visualized. In this study, a catheter is used to inject a contrast agent (dye) into the major blood vessel in the body. The amount of dye used depends on the size and function of the kidneys and renal blood flow.

- An arteriogram, also called an angiogram, is an X-ray image of the blood vessels. It is performed to evaluate various vascular conditions, such as an aneurysm (ballooning of a blood vessel), stenosis (narrowing of a blood vessel), or blockages.A cerebral arteriogram is an arteriogram of the blood vessels of the brain. cerebral arteriogram may be performed to locate clips on blood vessels placed during previous surgical procedures, and/or to evaluate the condition of such clipped vessels after a clipping procedure.

Computed tomography angiography CTA can be used to examine blood vessels in many key areas of the body, including the brain, kidneys, pelvis, and the lungs. Under some circumstances the coronary arteries may be examined by CTA, but CTA has not replaced invasive catheter coronary angiography. The procedure is able to detect narrowing of blood vessels in time for corrective therapy to be done. This method displays the anatomical detail of blood vessels more precisely than magnetic resonance imaging (MRI) or ultrasound. Today, many patients can undergo CTA in place of a conventional catheter angiogram.

Angiogram An angiogram is an invasive test, so it is not without risk. There is a very small risk of the catheter damaging your artery or loosening a piece of plaque lining the artery wall. This loose piece of plaque can travel up the artery into the brain and could block blood flow causing a stroke.

angiography magnetic resonance angiography. Noninvasive imaging of blood vessels by magnetic resonance imaging. The technique does not expose patients to ionizing radiation and avoids catheterization of the vessels. It has been used to study aneurysms, blockages, and other diseases of the carotid, coronary, femoral, iliac, and renal arteries.

Pulmonary Angiogram An angiogram is an X-ray image of the blood vessels. It’s also called an arteriogram. It’s done to look at blood vessels that have problems. A pulmonary angiogram is an angiogram of the blood vessels of the lungs. The procedure is done with a special contrast dye injected into the body’s blood vessels. This is done in the groin or arm. The dye shows up on X-rays.

- 1 A coronary computed tomography angiogram (CTA) uses advanced CT technology, along with intravenous (IV) contrast material (dye), to obtain high-resolution, 3D pictures of the moving heart and great vessels.2  CTA is also called multi-slice computed tomography (MSCT), cardiac CT or cardiac CAT. CTA is also called multi-slice computed tomography (MSCT), cardiac CT or cardiac CAT. 2  During CTA, x-rays pass through the body and are picked up by detectors in the scanner, that produce 3D images on a computer screen.

- Angiography is an X-ray exam of the arteries and veins to diagnose blockages and other blood vessel problems. An interventional radiologist performs this X-ray procedure, which is also called an angiogram.During the angiogram, the doctor inserts a thin tube (catheter) into the artery through a small nick in the skin about the size of the tip of a pencil.A substance called a contrast agent (X-ray dye) is injected to make the blood vessels visible on the X-ray.One of the most common reasons for angiograms is to see if there is a blockage or narrowing in a blood vessel that may interfere with the normal flow of blood through the body.In many cases, the interventional radiologist can treat a blocked blood vessel without surgery at the same time the angiogram is performed.ne of the most common reasons for angiograms is to see if there is a blockage or narrowing in a blood vessel that may interfere with the normal flow of blood through the body.

Magnetic Resonance Angiography (MRA) and Magnetic Resonance Venography (MRV) Note: As MRA is considered an alternative to angiography for evaluation of the carotids, a subsequent angiography would only be considered medically necessary if there was a significant discrepancy between the findings of Duplex ultrasonography and MRA that would impact on surgical planning.

Frequently Asked Questions About Contrast Material Usage 1 An angiogram is a specific type of CT scan with contrast. 2  In a CT angiogram the contrast is timed so that it will highlight either the arteries or veins (venogram) of interest. 3  For instance, a CT angiogram of the chest to evaluate for PE will have the timing set so the contrast is present in the pulmonary arteries.

Overview A coronary angiogram is a procedure that uses X-ray imaging to see your heart's blood vessels.Coronary angiograms are part of a general group of procedures known as heart (cardiac) catheterization. Heart catheterization procedures can both diagnose and treat heart and blood vessel conditions. coronary angiogram, which can help diagnose heart conditions, is the most common type of heart catheterization procedure. During a coronary angiogram, a type of dye that's visible by an X-ray machine is injected into the blood vessels of your heart.

Interventional Radiology Interventional radiology, or image-guided surgery, is a sub-specialty of radiology where minimally invasive procedures are performed using image guidance. Some of these procedures are done for purely diagnostic purposes (such as an angiogram), while others are done for treatment purposes (such as angioplasty).

Arteriogram An arteriogram is a procedure that produces an image of your arteries. Your doctor will use dye (called “contrast material”) and X-rays to observe the flow of blood through your arteries and observe any blockage.This procedure, also known as an angiogram, can be done on many different parts of the body.he terms “arteriogram” and “angiogram” (and the related “arteriography” and “angiography”) are not specific to a particular part of the body. They simply refer to a particular method of observing your arteries.

Computed Tomography Angiography (CTA) What is a CTA? CT angiography is a type of medical exam that combines a CT scan with an injection of a contrast media to produce pictures of blood vessels and tissues in a part of your body. The contrast is injected through an intravenous (IV) line started in your arm or hand.

About This Procedure A CT angiography (CTA) scan is a special kind of CT exam that focuses particularly on the blood vessels, using a contrast material to make them show up clearly in the images. Common uses. CTA is used to examine blood vessels in areas including the brain, neck, chest and abdomen. Conditions that the exam can reveal include aneurysms and narrowing of the arteries. Safety. CT examinations improve health care and are an essential part of diagnosis and treatment planning.
