Magnetic resonance imaging (MRI) uses a strong magnet and its supporting computer to produce images of amazing detail and clarity. MRI is the diagnostic procedure of choice for many diseases of the brain, spine, joints, and larger blood vessels. Additional applications of MRI include diseases of the chest, abdomen, and pelvis.
The innovative General Electric 1.5 Tesla MRI scanner at Clifton Park Advanced Imaging combines the outstanding image quality and short examination times attainable at high magnetic field strength with the comfort, roomy feeling, and ready patient acceptance of traditional open magnet designs. Our staff utilizes a variety of techniques and a sympathetic and understanding manner to assist claustrophobic patients through their examinations.
MRI examinations consist of several different pulse sequences, which involve changing scanner settings to highlight specific differences among body tissues. During the time that these pulse sequences are in operation, normal function of the magnet produces a humming or thumping sound. Each pulse sequence takes from several seconds to a few minutes. During acquisition of each pulse sequence, the MR computer collects information that is processed into the final, highly detailed images. Stacks of images may be obtained so as to sequentially section the body part of interest in any desired direction (i.e., side to side, front to back, or top to bottom). In some cases, the radiologist will need to give an intravenous injection of MR contrast agent to further aid in detection or diagnosis of potential abnormalities. In all, the MRI examination lasts from 20 to 40 minutes, depending of the number and duration of the pulse sequences required to fully evaluate your condition.
Due to the high magnetic field used in MRI, certain materials and devices are not allowed in close proximity to the magnet. Please inform our staff prior to your appointment if you have any of the following: cardiac pacemaker, implanted defibrillator, cerebral aneurysm clip, cardiac valve replacement, metal filings or fragments in the eye, metallic or electronic ear prosthesis, or a neurostimulator. See the MRI Patient Safety region of our website for more information. Our staff will be happy to assist your doctor in determining which patients with these materials or devices may safely undergo magnetic resonance imaging.
Although most types of MRI examinations require no special patient preparation, please read the Patient Preparation section of our website just to make sure.
Please inform our staff in advance if you are pregnant, nursing, or think that you might be pregnant.
