A magnetic resonance imaging or MRI is a test that generates images of the brain and adjacent tissue by use of radio waves and magnetic fields, states MedlinePlus. It's also known as an MRI of the head and is applicable in diagnosing brain conditions such as brain tumors and stroke.
A head magnetic resonance imaging scan, or MRI, is a test that produces images of the brain using a strong magnetic field and radio-wave energy, according to WebMD. It typically offers useful information that X-ray, ultrasound and computer tomography scans cannot provide.
According to WebMD, an MRI of the brain is a painless, non-invasive test in which a magnetic field and radio wave energy are used to take pictures of the brain and nervous tissues. A patient lies with her head inside a scanner machine that contains a strong magnet while pictures are taken with a spe
Magnetic Resonance Imaging, or MRI, scans of brain tumors are three-dimensional images of the brain created by radio waves and magnetic fields. MRIs are among the best types of imaging for diagnosing brain tumors, according to Johns Hopkins Medicine. An MRI has a higher sensitivity than a CT scan, w
The cost of a magnetic resonance imaging scan of the brain typically ranges from $1,000 to $5,000, according to CostHelper. The cost varies by location, complexity of the MRI and whether the scan is done in a hospital or office setting.
An MRI, or magnetic resonance imaging, is used to scan the body to identify problems in soft tissues, such as nerves, ligaments, tendons and muscles, according to Alliance Medical. An MRI highlights contrasts in soft tissues to identify infections or inflammatory conditions, too, according to the Ne
A white spot on a brain MRI, referred to as white matter or a brain lesion, shows an area of injury or disease, but can result in a number of diagnoses, according to the Mayo Clinic. The potential diagnoses range from harmless and controllable to possibly life threatening.
When an MRI is performed with contrast of the brain, a dye helps certain parts of the brain show up distinctly on the images, according to MedlinePlus. The patient typically receives the dye intravenously in the hand or forearm. If the scan is done without contrast, no dye is used.
Magnetic resonance imaging (MRI) is a noninvasive computerized diagnostic technique that uses strong magnetic fields and radio waves to develop an image of the inside of the body, according to Johns Hopkins Medicine. The process does not use potentially dangerous radiation the way that X-rays and CT
An Magnetic Resonance Imaging, or MRI, scan works by sending the patient through an enormous circular magnet, explains MedicineNet. The magnetic field aligns hydrogen atoms in the body in such a way that radio waves can move through and create a very faint signal that can be detected by the computer
