Magnetic resonance imaging (MRI) is an imaging diagnostic system using radio waves, a magnetic field, and a computer to visualize internal organs of the human body and obtain diagnostic information. An MRI displays images of the body in “slices” similar to that of a CT scan, but it is also able to reflect greater contrast between different types of body tissues.
MRI images are produced without the use of radiation and there are no known side or after-effects. The procedure is painless, noninvasive, and you won’t see or feel anything during the exam. A faint knocking sound will be heard, which is the imaging process in operation. In some instances, contrast agents, such as gadolinium, are used to enhance certain anatomical structures and increase the diagnostic accuracy of the images.
Magnetic resonance imaging is used for virtually all parts of the body and is one of the advanced imaging techniques utilized at Akumin. In addition to its use to view precise details of the head, neck, spine, muscles, joints, and bones, it is also used to image the chest, abdomen and pelvis. Frequently, the differentiation of abnormal (diseased) tissue from normal tissues is better with MRI than with other imaging modalities such as X-ray, CT, and ultrasound.
Open MRI is the kind of MRI that is used for mainly claustrophobic, pediatric, or obese patients. Traditional MRI scanners are a cylinder shape and can be noisy. For some patients, this causes a lot of anxiety and they sometimes avoid or delay undergoing the exam completely. An open MRI helps alleviate some of these concerns since instead of being an enclosed capsule, these machines do not fully surround the patient’s body and are typically open on two or three sides. They also produce lesser noise levels making the duration of the scan less stressful for the patient.
Due to the shape of the open MRI, it is not always possible to take images of certain areas of the body and the images it produces can be of lesser quality as the magnet strength of the open MRI is less than that of a closed or wide-bore MRI. For this reason, an open MRI is not always an option for all patients and some scans must be performed on a traditional closed MRI machine.
Akumin offers open MRI imaging at over 43 center locations in 6 states. Visit our Locations page for a full list of centers and their service offerings.
Upright Open MRI
Available at select locations*
Akumin is proud to offer the latest high field, full-body upright open MRI scanner that can scan patients in the sitting or standing position. This technological breakthrough is second to none in the MRI imaging world, and can be reimbursed by most insurance carriers at no additional cost to the patient.
Conventional MR and CT systems are designed so that the patient is scanned in the horizontal position (typically supine) whereas with a Stand-up Open MRI, physicians have the ability to see all the body’s organs and soft tissues in a variety of positions that include flexion, extension and rotation.
This is especially important when dealing with certain cardiovascular and neurological disorders that exhibit their symptoms primarily when the patient is upright. The same is true of the GI tract and the spine and joints, including hips, knees and ankles.
Patients who might be considered for upright open MRI include:
- Patients who are claustrophobic
- Patients who are obese or exceptionally large (including some endocrine patients)
- Patients who are unable to lie supine for the duration of their scan
- Patients who need to be observed in upright or seated positions during their scan
Benefits of an upright open MRI
- Image quality is exceptionally good, and all studies are reported by specialist radiologists
- Claustrophobia is not a problem with this scanner
- It can be used in a variety of clinical situations where conventional MRI is unsuitable
- It can sometimes reveal pathology not identified with conventional MRI
*Upright open MRI is currently offered at the following Akumin center locations.
- West Florida: Boot Ranch, Sarasota, St Petersburg
