A brain perfusion scan is a type of brain test that shows the amount of blood taken up in certain areas of your brain. This can provide information on how your brain is functioning. There are several different types of brain perfusion scans. Some tests, such as a single photon emission computed tomography (SPECT) or a positron emission (PET.

The following protocols are an updated list of the Neuroradiology MRI protocols for all of the MRI sites at which TRA Medical Imaging is responsible for the administration, quality and interpretation of Neuroradiology MRI examinations. The protocols were changed in an attempt to standardize the sequences performed at each of the sites and to. e-MRI : an interactive online course about MRI physics. e-MRI presents an interactive course about magnetic resonance imaging physics. Magnetic resonance imaging (MRI) is a medical imaging technique used to produce high quality images of the human body. In 2003, Paul C.

The maximum intensity projections of this magnetic resonance angiography ( MRA) are inverted to provide high vessel contrast. High field MRI ( 3T) provides the high signal to noise ratio and spatial resolution that are important when imaging flow within the intracranial vasculature. The used 3D time of flight angiography ( TOF) provides the. An MRI scan can be used to examine almost any part of the body, including the: brain and spinal cord ; bones and joints ; breasts ; heart and blood vessels ; internal organs, such as the liver, womb or prostate gland The results of an MRI scan can be used to help diagnose conditions, plan treatments and assess how effective previous treatment. Contrast-enhanced MRA technique. Contrast-enhanced MRA (CE-MRA) is based on a T1-weighted 3-dimensional (3D) gradient-echo acquisition, most often in the coronal plane to get the largest possible coverage (which is the 25- to 35-cm field of view, rather than the usual 1- to 2-mm slice thickness of unenhanced MRA techniques).

A single scan may take from a few seconds to 3 or 4 minutes. You may be asked to hold your breath during short scans. Depending on the size of the area being scanned and how many images are taken, the whole procedure will take 15 to 90 minutes. The MRI scanner will make loud tapping noises at certain times during the procedure. Plan the sagittal 3D or 2D block on the axial plane; angle the position block 10° to midline of the brain. Check the positioning block in the coronal plane and angle 10° to midline of the brain. This angulation is to reduce the in plane saturation effects.
