MRI High Field Scanner and Open MRI Scanner
Breast, Body and Vascular
Rye Radiology Associates has added a 1.5 Tesla high field MRI to our practice in addition to our open MRI. The advanced imaging capabilities of our 1.5 Tesla high field system enables us to perform high resolution MRI of the breasts with 3-D CAD analysis of the images. Breast MRI may be used to screen women who are at high risk for breast cancer. The magnetic resonance imaging suite is specifically equipped with MRI compatible vacuum assisted needle biopsy capabilities allowing us to perform guided breast biopsies on lesions which show up only on Magnetic
Resonance Imaging and are not present on mammography or ultrasound.
In addition to being able to perform imaging on joints, head, spine, chest, abdomen and pelvis, this 1.5 Tesla high field MRI has advanced MR angiography capabilities. The MRI has a larger opening than most high field units in current use and is designed to accommodate patients weighing up to 550 lbs.
Of course, for those patients who cannot tolerate even this very comfortable high field MRI, we continue to provide Magnetic Resonance Imaging services on our open Aris-II Hitachi MRI.
How Magnetic Resonance Imaging Works:
MRI is painless, non-invasive and does not use ionizing radiation. The MRI equipment uses a magnetic field rather than x-ray to produce images. The magnetic field forces hydrogen atoms in the body to line up in a certain way (similar to how the needle on a compass moves when you hold it near a magnet). When radio waves are sent toward the lined-up hydrogen atoms, they bounce back, and a computer records the signal. Different types of tissues send back different signals.
The study can produce dozens to hundreds of images with no radiation.
Some exams require contrast injection. The contrast allows for better visualization of some body structures.
Depending on the type of exam that you are having you may be asked to change into a gown. Jewelry or any metal objects should be left at home. Please inform us if you have a heart and blood vessel device such as a coronary stent, pacemaker or ICD, any metal in your body such as clips, a medicine infusion pump, cochlear implant or cosmetic tattoos. Since the exam is performed with a very powerful magnet it is imperative that no metal objects are brought into the MRI suite. A locker will be provided for any personal items such as eyeglasses and clothing that may have to be removed for the exam.
Results of your exam are faxed to your doctor within 24 hours and we will contact your doctor immediately to discuss any abnormal results.
