Magnetic resonance pulmonary angiography (MRPA) should be considered only at centers that routinely perform it well and only for patients for whom standard tests are contraindicated. Technically-adequate magnetic resonance angiography has a sensitivity of 78% and a specificity of 99% 13 .
MR angiogram techniques. The types of MR angiograms can be broadly separated out into two types: dark blood and bright blood. The bright blood techniques are then further subdivided according to whether they use gadolinium or not. The main ones used are time-of-flight, phase contrast and contrast-enhanced techniques.

11-13 CT angiography (CTA) and MRA combined have the potential to replace catheter angiography for diagnosis (Figures 1 and 2). A thin-section (1.25 mm/2.5 mm), contrast-enhanced MDCTA is performed with 3D volu-metric and MIP reformations. Traditionally, 2D/3D TOF had been the MR imaging technique. MR angiography and MR urography are noninvasive diagnostic modalities with the potential to replace angiography and pyelography.

MR Angiography (MRA) MR angiography (MRA) uses a powerful magnetic field, radio waves and a computer to evaluate blood vessels and help identify abnormalities. This exam does not use radiation and may require an injection of contrast material. The contrast material used for MRA is less likely to cause an allergic reaction than the contrast Magnetic resonance angiography (MRA) is a very valuable tool in the routine evaluation of patients with stroke syndrome. It provides powerful noninvasive imaging of the cervical and intracranial vessels allowing the detection and the diagnosis of vascular anomalies. MRA usefully supplements, during ….

How do you create an MR angiogram? Why would you want to choose dark blood over bright blood for MRA? Can't you just invert the bright blood image on a monitor and get the same effect?

A coronary angiogram is a procedure that uses X-ray imaging to see your heart's blood vessels. The test is generally done to see if there's a restriction in blood flow going to the heart. Coronary angiograms are part of a general group of procedures known as heart (cardiac) catheterizations. River Bend Imaging, located in LaPlace, Louisiana is a patient friendly, diagnostic testing facility offering MRI imaging services and Ultra Sounds in a conveniently located and comfortable setting.
MRA provides detailed images of blood vessels and sometimes requires a special form of contrast material that is used to make the images even clearer. MR angiogram techniques. The types of MR angiograms can be broadly separated out into two types: dark blood and bright blood.
