Magnetic resonance imaging (MRI), nuclear magnetic resonance
MRI: We perform congenital pediatric and adult cardiac/chest/heart MRI and MRA (MR angiogram) imaging. MRA of the thoracic and abdominal aorta, pelvic arteries and lower extremity arteries run off (diagnosing aneurysm, stenosis, peripheral vascular disease (PAD). MRI and MRA of the kidneys for renal artery stenosis. Fetal MRI. 2nd and 3rd trimester MRI for placenta and high risk OB/GYN. MRI enterography (MRI of the gastrointesitnal tract). Specialized MRI of the pelvis for uterus, ovaries, prostate. Advanced Neuroimaging of brain, IACs (Internal Acoustic Canal), pituitary, seizure, neck, brachial plexus and spine imaging. MRI spectroscopy and perfusion imaging. Advanced stroke imaging including CT perfusion
Imaging (NMRI), or magnetic resonance tomography (MRT) is a medical imaging technique used in radiology to visualize detailed internal structures. MRI makes use of the property of Nuclear magnetic resonance (NMR) to image nuclei of atoms inside the body. There is no radiation.
An MRI machine uses a powerful magnetic field to align the magnetization of some atoms in the body, and radio frequency fields to systematically alter the alignment of this magnetization. This causes the nuclei to produce a rotating magnetic field detectable by the scanner—and this information is recorded to construct an image of the scanned area of the body. Strong magnetic field gradients cause nuclei at different locations to rotate at different speeds. 3-D spatial information can be obtained by providing gradients in each direction.
MRI provides good contrast between the different soft tissues of the body, which make it especially useful in imaging the brain, muscles, the heart, and cancers compared with other medical imaging techniques such as computed tomography (CT) or X-rays. Unlike CT scans or traditional X-rays, MRI uses no ionizing radiation.
