MR angiography. MR angiography facilitates non-invasive, high resolution images of the blood vessels. A special characteristic of this technique is its three-dimensional representation that allows for a vessel assessment from different angles as well as of conditions such as vascular constrictions or vascular dilations (e. g. aneurysm).
Magnetic resonance angiography (usually shortened to MR angiography or MRA) is an alternative to conventional angiography and CT angiography, eliminating the need for ionizing radiation and iodinated contrast media, and sometimes contrast media altogether. It has evolved into several techniques with different advantages and applications: contrast enhanced MR angiography (MRA)

Physician biography of Ben Yang, M.D., D.A.B.R., radiologist at Larchmont Medical Imaging Abstract. The accuracy of 3D time of Flight Magnetic Resonance Angiography (TOF MRA) has been studied extensively for following coiled intracranial aneurysms. It is used by many clinicians for non-invasive follow-up because of its adequate sensitivity in predicting aneurysmal recanalization compared to diagnostic cerebral angiography. Free-breathing coronary MR angiography was superior to breath-hold coronary MR angiography both in terms of image quality and diagnostic accuracy, with the sensitivity and specificity of 72% and 92%, respectively, by using free-breathing MR angiography and the sensitivity and specificity of 63% and 82%, respectively, by using breath-hold MR angiography.
MRA provides detailed images of blood vessels without using any contrast material, although today a special form of contrast usually is given to make the MR images even clearer. Three MR angiography sequences (3D PCA, 2D TOF, and multi-slab 3D TOF) and a proton density (PD) weighted sequence were reviewed by four neuroradiologists. The gold standard was digital subtraction angiography.

MR angiography is less costly than catheter angiography. Even without using contrast material, MRA can provide useful high-quality images of many blood vessels.

The main ones used are time-of-flight, phase contrast and contrast-enhanced techniques. 2 dagar sedan · 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 test.
