Alfa Scan is proud to announce the presence of the first 3 Tesla MRI scanner in Egypt in Maadi branch. 1.5 Tesla MRI scanners are also available in Mohandeseen and Helioplis branches as well as Open MRI machines.

What is an MRI scan?

An MRI (or magnetic resonance imaging) scan is a radiology technique that uses magnetism, radio waves, and a computer to produce images of body structures.

The MRI scanner is a tube surrounded by a giant circular magnet. The patient is placed on a moveable bed that is inserted into the magnet. The magnet creates a strong magnetic field that aligns the protons of hydrogen atoms, which are then exposed to a beam of radio waves. This spins the various protons of the body, and they produce a faint signal that is detected by the receiver portion of the MRI scanner. The receiver information is processed by a computer, and an image is produced.

The image and resolution produced by MRI is quite detailed and can detect tiny changes of structures within the body. For some procedures, contrast agents, such as gadolinium, are used to increase the accuracy of the images.

When are MRI scans used?

An MRI scan can be used as an extremely accurate method of disease detection throughout the body. In the head, trauma to the brain can be seen as bleeding or swelling. Other abnormalities often found include brain aneurysms, stroke, tumors of the brain, as well as tumors or inflammation of the spine.

Neurosurgeons use an MRI scan not only in defining brain anatomy but in evaluating the integrity of the spinal cord after trauma. It is also used when considering problems associated with the vertebrae or intervertebral discs of the spine. An MRI scan can evaluate the structure of the heart and aorta, where it can detect aneurysms or tears.

It provides valuable information on glands and organs within the abdomen, and accurate information about the structure of the joints, soft tissues, and bones of the body. Often, surgery can be deferred or more accurately directed after knowing the results of an MRI scan.

What are the risks of an MRI scan?

An MRI scan is a painless radiology technique that has the advantage of avoiding x-ray radiation exposure. There are no known side effects of an MRI scan. The benefits of an MRI scan relate to its precise accuracy in detecting structural abnormalities of the body.

You cannot have an MRI if:

  •  IF YOU HAVE A CARDIAC PACEMAKER or NEUROSTIMULATOR.

  • If you have CEREBRAL ANEURYSM CLIPS contact us immediately. Depending on the type of clip, we may not be able to perform an MRI.

  • If you have any other type of biomedical implant, please call our hotline 16171 or (202) 3336-3310 (Mohandeseen), (202) 2417 5556 (Heliopolis) or (202) 2528 4888 (Maadi) to speak with a radiologist if you have any questions. It is best to call between 10 a.m. and 10 p.m., Saturday through Thursday, because the MRI exam may not be possible.

  • Also tell us if you had any brain, eye, ear or other surgery or if you are pregnant.

  • Please call us if you weight over 130 Kgs.

  • If you are CLAUSTROPHOBIC or a young child or semi or unconcious, please call us; we may need to schedule your appointment for specific times with sedation

Preparation/instructions

    When you were referred by your physician for a radiological exam, you may have been told about certain instructions to be done prior to the exam, or when you were scheduling your appointment, the scheduler should have informed you about the preparations that should be done prior to your exam. If you did not or if you want a recheck, you can refer to the information listed below.

    Keep in mind that you may have been given some additional or different instructions, based on your own particular circumstances. If you have any questions, please call our hotline 16171 or (202) 3336-3310 (Mohandeseen), (202) 2417 5556 (Heliopolis) or (202) 2528 4888 (Maadi) to speak with a radiologist if you have any questions. It is best to call between 10 a.m. and 10 p.m., Saturday through Thursday.

Instructions

    Bring referrals and insurance information along with your prescription or request slip. Bring with you any other studies (CT scans, x-rays, ultrasound) that were performed at Alfa Scan or other hospitals so that we can better interpret and plan your MRI examination.

    Please plan on arriving 15 minutes before your examination. If you do not arrive on time it is possible that we may need to reschedule your study for another day.

   For your safety, you will be asked questions concerning implants and metal by technologists and physicians. You will also be asked to remove ALL jewelry, watches, hair clips, dentures, glasses and hearing aides. It may be easiest if you wear as few of these items as possible. You will be asked to place all items including your credit cards and wallet into a your changing suite and change into a patient gown.

The procedure

    One of our radiologists will discuss your health history and can answer any questions that you might have.

    The MRI technologist will help you get onto the scan table and position you for the exam. The table will slide into a cylinder shaped unit. There is an intercom system so that you can hear and talk to the technologist who is operating the scanner.

    During the exam you will hear a knocking sound. It is important that you hold perfectly still during this knocking sound. The study takes 30-60 minutes, depending on the type of scan required. The scan is very sensitive to motion. If you move even a little during the scan, the entire scan may need to be repeated.

    Certain exams may need an injection of contrast material (Gadolinium) to better visualize the area of interest. This requires an intravenous injection towards the end of the procedure.

After Care

    You can resume your normal activities immediately after the examination.

        The radiologist's report of the results will be ready within 24 hours. Your doctor will discuss the results of the test with you.
