Magnetic Resonance Imaging (MRI) of the Spine and Brain
Magnetic resonance angiography (MRA) is a new procedure used to evaluate blood flow through arteries in a noninvasive (the skin is not pierced) manner. MRA can also be used to detect intracranial (within the brain) aneurysms and vascular malformations (abnormalities of blood vessels within the brain, spinal cord, or other parts of the body).
Magnetic Resonance Imaging (MRI) - Johns Hopkins Medicine
Magnetic resonance imaging, or MRI, is a noninvasive medical imaging test that produces detailed images of almost every internal structure in the human body, including the organs, bones, muscles and blood vessels. MRI scanners create images …
Magnetic Resonance Angiography (MRA) - Johns Hopkins Medicine
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.
Brain Aneurysm: 4 Things You Need to Know - Johns Hopkins Medicine
This causes severe symptoms, such as a very painful headache like you've never felt before, and requires immediate medical care. With rapid, expert treatment, patients can often recover fully. An unruptured brain aneurysm may cause zero symptoms. People can live with them for years before detection.
CT Scan Versus MRI Versus X-Ray: What Type of Imaging Do I …
Learn the differences between a CT scan, MRI and X-ray so you can have an informed discussion with your doctor about which type of imaging is right for you. CT scans, MRIs and X-rays are all diagnostic tools that allow doctors to see the internal structures of the body.
Brain Perfusion Scan - Johns Hopkins Medicine
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.
Increased Intracranial Pressure (ICP) Headache
This test makes a series of detailed X-ray images of the head and brain. MRI. This test uses a large magnet and a computer to detect small changes in brain tissue content. It can show more detail than X-rays or a CT scan.

Diagnosis and Screening for Neurological Conditions
Magnetic resonance imaging (MRI) uses radiofrequencies, powerful magnets and a computer interface to provide a clear and detailed view of soft tissue and organs in the body, including the brain. Special applications of magnetic resonance imaging include magnetic resonance angiography (MRA) and magnetic resonance venography (MRV).
