Patient Information

What is MRI?

Since its introduction in the early 1980's, MRI has emerged as an imaging technology that is excellent for diagnosing of brains, spines, knees, etc. with technology that is continually changing. We offer the latest MRI technology available today. MRI or Magnetic Resonance Imaging is a unique procedure that uses a strong magnetic field and radio waves to look inside the human body. It is an important addition to existing diagnostic tools because it is a painless procedure which offers your physician unprecedented detailed images of the human body without using ionizing radiation (x-rays). The procedure works with radio waves directed at protons in your body. The protons are first "excited" and then "relaxed" the relaxed state generates radio signals, which can be computer-processed to form an image. The MRI image shows differences in the water content and distribution in various body tissues. Even different types of tissue within the same organ, such as the gray and white matter of the brain can be distinguished. Typically a MRI exam consists of two to six imaging sequences, each lasting two to fifteen minutes. Each sequence has its own degree of contrast and shows a cross section of the body.

Hallmark Health Imaging offers the best of High Field MR Imaging along with Open MRI.

Claustrophobic Patients

If you are claustrophobic, the CHEM Center now has an open magnet. The Hitachi Airis II magnet is open on four sides, which minimizes anxiety and claustrophobia. This design also allows you to have a family member or friend with you at your side during the exam to comfort you further.

Anyone concerned about the exam is welcome to come by the Center prior to his or her scan in order to view the magnets and to speak with our staff.

Films/Reports

If you need additional films or copies of your report, please call us ahead of time. A charge may apply if you have already received them at the time of your scan. Calling ahead will assure your films will be ready. It takes the center additional time today to prepare them as most cases are handled electronically or are off site.

If you have any questions please call 781-279-2213.

Tests & Sample Images

MRI is a convenient and safe diagnostic procedure for most patients. During the scan, you experience no physical sensations. There is a loud knocking sound, which is the sound of the switching of the magnetic fields. This sound can be minimized by the use of earplugs.

Most exams do not require any preparation except for MRCP (Magnetic Resonance Cholangiopancreatography) which require that you have nothing to eat or drink after midnight. Take medications as prescribed.

Some exams performed may require an injection of a contrast agent known as gadolinium. This contrast agent enhances areas in the body that will aid the radiologist in the interpretation of your exam. If you would like to know if you require an injection, please call the CHEM Center for MRI at 781-279-2213.

Magnetic Resonance Imaging (MRI)

Brain MR Imaging
MRI of the brain is the procedure recognized as yielding the most diagnostic information for evaluation of many brain diseases and anomalies. The spectacular high resolution images allow radiologists to view lesions as small as 1mm.

Cervical MR Imaging
MRI of the spine has been the procedure recognized as yielding the most diagnostic information for evaluation of primary or metastatic tumors of the spinal cord. MR imaging of other anatomical structures of the spinal cord such as nerve roots, neural foramina, ligament and disc spaces is further enhanced by exceptional resolution and contrast without bone artifacts which are common in CAT scan procedures. MR provides a highly effective alternative to myelography.

Thoracic MR Imaging
MRI of the spine has long been the procedure recognized as yielding the most diagnostic information for evaluation of primary or metastatic tumors of the spinal cord. MR imaging of other anatomical structures of the spinal cord such as nerve roots, neural foramina, ligament and disc spaces is further enhanced by exceptional resolution and contrast without bone artifacts which are common in CAT scan procedures. MR provides a highly effective alternative to myelography.

Lumbar MR Imaging
MRI of the spine has long been the procedure recognized as yielding the most diagnostic information for evaluation of primary or metastatic tumors of the spinal cord. MR imaging of other anatomical structures of the spinal cord such as nerve roots, neural foramina, ligament and disc spaces is further enhanced by exceptional resolution and contrast without bone artifacts which are common in CAT scan procedures. MR provides a highly effective alternative to myelography.

It is also useful in post-operative patients to distinguish between scar and recurrent disc disease in which you will receive a contrast injection.

Shoulder MR Imaging
MRI offers the best of all imaging because of its superior contrast differentiation between muscle, fat, vessels, tendons, ligaments, cartilage, cortical bone marrow and marrow bone space. High-resolution imaging techniques provide unparalleled detail of the menisci and ligaments.

Elbow MR Imaging
MRI offers the best of all imaging because of its superior contrast differentiation between muscle, fat, vessels, tendons, ligaments, cartilage, cortical bone marrow and marrow bone space. High-resolution imaging techniques provide unparalleled detail of the menisci and ligaments.

Wrist Imaging
MRI offers the best of all imaging because of its superior contrast differentiation between muscle, fat, vessels, tendons, ligaments, cartilage, cortical bone marrow and marrow bone space. High-resolution imaging techniques provide unparalleled detail of the menisci and ligaments.

Liver MR Imaging
MRI of the liver offers unmatched sensitivity to pathology compared to CT in the detection of primary and metastatic liver tumors. Abdominal MR, has been radically improved with recent software and hardware innovations which provides faster imaging techniques.

MRCP (Magnetic Resonance CholangioPancreatography)
MRI of the biliary system has advantages over traditional methods. MRCP has been radically improved with recent software and hardware innovations, which provides faster imaging techniques. The use of this technique aids in the detection of gall bladder and pancreatic duct obstructions.

Pelvis MR Imaging
MRI of the pelvis offers the advantages of improved soft tissue discrimination and absence of bone artifacts. It aids in the diagnosis of ovarian tumors and soft tissue masses. Also, without the use of ionizing radiation, MRI provides for safe imaging of the reproductive organ of adults.

Knee MR Imaging
MRI offers the best of all imaging because of its superior contrast differentiation between muscle, fat, vessels, tendons, ligaments, cartilage, cortical bone marrow and marrow bone space. MRI also displays excellent delineation of tumors of soft tissue and bone as well as avascular necrosis of bone. High-resolution imaging techniques provide unparalleled detail of the menisci and ligaments.

Magnetic Resonance Angiography (MRA)

Brain and Carotid MRA
MRA is a non-invasive procedure that provides the capability to visualize the vascular structures of the human body. The images are reconstructed using a technique that enables three-dimensional viewing. It is useful in the diagnosing of aneurysms, vascular malformations, occlusions, stenosis, thrombosis, and vascular tumors.

Renal MRA
MRA is a procedure that provides the capability to visualize the vascular structures of the human body. This exam requires the injection of a contrast agent. The images are reconstructed using a technique that enables three-dimensional viewing. It is useful in the diagnosing of aneurysms, vascular malformations, occlusions, stenosis, thrombosis, and vascular tumors.

Lower Extremity MRA
MRA is a procedure that provides the capability to visualize the vascular structures of the human body. This exam requires the injection of a contrast agent. The images are reconstructed using a technique that enables three-dimensional viewing. It is useful in the diagnosing of aneurysms, vascular malformations, occlusions, stenosis, thrombosis, and vascular tumors.


Patient Instructions

You will be asked to arrive 1/2 hour before your appointment time. This time is used to register, screen, obtain medical history, prepare and inform you of your exam. No special preparations are necessary for a MRI scan (except for MRCP). Eat, drink, and take medications as you normally do.

The registration process includes obtaining your demographic and insurance information.

The MR Technologist will then escort you to a separate waiting room were we will begin the screening and medical history procedure. Most patients with joint replacements or other orthopedic hardware do not present a problem and still can be scanned, but because MRI uses powerful Magnetic Fields, some patients may be excluded from having a MRI.

If any of the following conditions exist please notify us before your exam.

  • Cardiac Pacemaker
  • Cerebral Aneurysm Clips
  • Cochlear Implants
  • Implanted Insulin or Chemotherapy Pumps
  • Implanted Neuro-Stimulator Devices
  • Pregnancy
  • Heart Valve Replacements
  • Other Prosthetic Devices
  • Metal Fragments in Eye

When the screening process has been completed some patients maybe asked to change into a gown. We offer lockers to secure your valuables. Please leave all jewelry and valuables at home.

You will then be escorted to the MRI scan room to begin your exam. You will be asked to lie on a padded table. It is important that you lie very still while the images are being taken. A MRI Technologist will be right outside the exam room and will be able to see and hear you the entire time. If you are uncomfortable, just say so and the technologist will be right in.

During the exam process the MR scanner makes a very loud repetitive noise. This process is a result of the changing of the magnetic field to collect the data. Earplugs are provided for you to minimize the sound.

Music is available for the OPEN MRI scanner. The High Field scanner produces a much louder noise and will interfere with your enjoyment of the music.

When the exam is complete, you will be escorted back to your dressing room. Some patients may be asked to wait for their MRI pictures to bring with them back to their physician.

What will happen to me during the screening and registration process?

Screening is the process that takes place before your MRI exam and includes the taking of a medical history and individual instruction regarding the exam.

You will be registered the day of your exam. This process takes about 15-30 minutes. You will be asked to provide your medical history in detail and sign consent forms. The technologist performing your exam will thoroughly explain the procedure and answer all your questions.

What will my exam be like?

During your MRI exam, you will lie on a padded table, which will slide into the magnet that is open on both ends. It is important that you lie very still while the images are being taken. An MRI technologist will be right outside the exam room and will be able to see and hear you the entire time. If you are uncomfortable, just say so and the technologist will be right in to assist you.

What will my exam feel like?

You will not feel anything. Remember, this is a painless procedure. The scanner has no moving parts but does make a repetitive knocking noise similar to a drumbeat as it collects information. Music or earplugs are provided to reduce the noise. You may receive an injection to enhance the images.

Can I bring a friend or family member?

A friend or family member is welcome, but they must be screened for conditions that would prevent them from joining you in the scan room.

Can I bring CD's, or listen to music?

Music is available for the Open MRI scanner. The High Field scanner produces a much louder noise and will interfere with your enjoyment of the music.

When will I know the results of my scan?

The images of your exam will be read by our Board Certified Radiologist. The report of your exam is available to your physician generally within 24 hours. Your doctor will discuss your test findings with you.

What if I need to cancel?

If you need to cancel your exam, PLEASE call us at least one day in advance at (781) 279-2213.

Are there any possible risks associated with MRI?

Extensive testing was done on MRI before it was approved for medical use. There are no known adverse effects from the MRI imaging process itself. At present, MRI scans are not routinely recommended for pregnant women in the first trimester.

What if I am claustrophobic?

The CHEM Center now has an open magnet for those patients who are claustrophobic. The Hitachi Open Magnet was designed to easily accommodate anxious and claustrophobic patients.

Additionally, if you are severely claustrophobic, you should speak with your physician who may prescribe a sedative. If you are taking a sedative, you must be accompanied by an adult who is responsible for getting you to and from your appointment.

Anyone concerned about the exam is welcome to come by the Center prior to his or her scan in order to view the magnets and talk with our staff.

Referring Physicians

Important Referral Reminder

It is a Medicare/Medicaid requirement that all diagnostic procedures performed must be specifically ordered in writing by a physician who treats the patient. We are also now finding that many other insurance companies are expecting that patients will have a written order for all MRI testing. Please remember to note that the patient was referred for a MRI scan in your office documents and give the patient a written order as well. If more convenient please fax the order prior to your patient's exam. Our fax number is (781) 279-0869.

Also please note that some insurers, including Harvard/Pilgrim and CIGNA/Healthsource, mandate that we must have a pre-certification number prior to our making your patient's appointment.

Advantages for Referring Physicians

Convenient Appointment Times: Please call 781-279-2213.

Turnaround Time for Results: Studies are read promptly by full time on-site radiologist with reports available within 24 hours. Stat reporting of results will be FAXED to the referring physician's office.
