MRI

The 2003 Nobel Prize for medicine was awarded to two scientists who played a key role in the development of the Magnetic Resonance Imaging (MRI) scan. Since its introduction in 1970's, MRI has changed the practice of medicine.

At Main Street Radiology, the MRI division is composed of four sections: Neuroradiology, Musculoskeletal radiology, Breast Imaging and Body imaging. We offer the 1.5 Tesla Siemens Open Bore MRI, 3 Tesla Siemens Verio, and Skyra Magnets. Main Street Radiology also performs prostate imaging using the I-Cad prostate system and the Breast MRI with Sentinelle coils to better evaluate cancer.

mri-fig2.jpgThere are six board-certified, fellowship-trained neuroradiologists at MSR. Their specialty encompasses diseases of the brain, spine, head, and neck. MRI exams are performed to evaluate common problems such as headaches and back pains. MRA (magnetic resonance angiography) is also routinely performed to evaluate the blood vessels of the neck and brain with and without contrast.

At MSR we also have sophisticated software usually found only at major academic hospitals, to perform specialized studies such as MR spectroscopy and perfusion/diffusion imaging, to better evaluate disease processes such as brain tumors and strokes.

mri-fig3.jpgMusculoskeletal MRI section at MSR is headed by Dr. Ari Jonisch. He is one of handful of fellowship-trained musculoskeletal radiologists in New York City. MRI is used to evaluate the joints, bones, and muscles of the extremities. Our radiologists routinely study patients with sports injuries, arthritis, tumors, and many other disease processes. With our high-field (3T) MRI and specialized coils, we can obtain high-resolution images of small parts, such as the wrists and feet, superior to low-field and open MRI units.

There are five fellowship-trained body imagers at MSR. Body MRI section performs exams of the chest, abdomen, pelvis, breasts, and cardiovascular system. With our advanced hardware and software, we perform studies not performed by most radiology facilities, including MRCP (magnetic resonance cholangiopancreatography), breast MRI, MRA of lower extremities, and MR urography.

We offer some of the latest exams in MRI imaging, including prostate and breast imaging, as well as imaging of abnormalities from the renal arteries to the vessels in the foot and legs. We utilize I-Cad software to perform MRI’s of the prostate so any complex lesions are enhanced and easier to identify. With breast imaging, we use the latest Sentinelle® technology which increases our ability to recognize lesions of the breast. We are able to perform Claudication studies to show the vessels of the legs with the smallest amount of contrast, which aids our Radiologists in visualizing any irregularities in vessels from the renal arteries down to the legs and foot. In addition, we utilize 3T Magnet for all Orthopedic imaging offering enhanced images of the joints and long bones.

Preparation for Procedure

To prepare for a MRI scan, we ask that you follow the following guidelines:

  • For a regular MRI exam, you can eat and drink as normal.
  • You may take all prescribed medications.
  • For certain MRI exams such as MRCP. MRAs of the abdomen and an MRI of the abdomen, pelvis and liver, please do not eat or drink anything (including water) 4 hours before the exam.
  • Please do not wear any item that is metal – including watches, hair pins, hearing aids, eyeglasses and jewelry. Please also do not wear any clothing that does not contain metal buttons, snaps or zippers.
  • If you are, or think you may be pregnant please let us know as an MRI is not generally performed on pregnant women.
  • It is important to also inform us if you have metal implants or objects such as insulin pump implants, metal fillings, TENS units, pacemaker, vascular clips, etc.

What to bring and wear:

  • Bring any previous MRI information with you.
  • Bring your insurance cards, prescription and photo ID.
  • Comfortable clothing that doesn’t contain metal buttons, snaps or zippers

Arrive on time:

  • You should arrive at least 15 minutes before your scheduled appointment time.
  • If you must cancel or reschedule, you need to do so at least 24 hours before your appointment.

Your MRI Scan:

  • After registering, you will be given forms to complete.
  • The MRI technologist will then review your medical history with you and explain what will happen during the procedure.
  • During the procedure, you will be asked to lie still and not to move as any movement can cause blurring on the image.
  • You will hear a loud knocking sound and feel some vibration, which is normal.
  • Depending on the type of MRI scan, the procedure can take approximately 20 to 60 minutes.
  • You can resume your normal diet and activities after the scan.

If you have any questions regarding your exam please give us a call at (718) 428-1500.
