The tapping and knocking noise you hear during your scan is caused by magnetic coils that switch on and off during the scan. These coils measure the signal coming from your body in order to make the images that are used for your diagnosis. Because these coils are switched on and off rapidly, they vibrate and cause the noise you hear. Since these noises are often very loud, the technologist will give you some type of hearing protection.

The technique of MR imaging employs magnetic fields called gradient fields that are used to determine the location of signals generated in the MRI process. These powerful gradient fields are switched off and on at a very fast rate and the result is a banging sound. Patients have described the sound as that of a broken washing. You will be provided with hearing protection to dampen this noise. See similar questions...

It’s a large, wide tube that’s open at both ends and is both bright and well-ventilated. It’s also equipped with a two-way intercom so you can communicate with the technician throughout the procedure. See similar questions...

The MRI scanner examines one area of the body at a time. The MRI scanner can take pictures of the head, neck, back, abdomen, pelvis, shoulder, elbow, knee, ankle, foot, blood vessels and more. MRI is predominantly excellent at distinguishing soft tissues such as imaging the brain, spinal cord and joint structures. See similar questions...

Currently the scanner MUST have a 1.5T magnet. The FerriScan technology has not yet been extended to scanners with other field strengths. See similar questions...

State law requires that vehicles responding to an emergency must use both red lights and sirens. We do try to respect the community and the surrounding homes close to all of our fire stations in the early morning hours. See similar questions...

Yes. In fact, Let's Make Some Noise has been errated (see below) to allow it to trigger anytime Road Dogg discards a card, for whatever reason. So, when Road Dogg uses his ability, Let's Make Some Noise will trigger. If he discards to a Half Hour Suplex, his ability will trigger, etc. This is opposite of Edge & Christian's Superstar ability which only triggers when they must discard a card.

Although usually silent, caribou do vocalize at certain times. During the rut, bulls frequently pant and bellow, and for several months after calving, mothers and calves grunt back and forth to each other. Click here to listen to the sounds that calves make. Caribou often snort for a variety of reasons, but the most common sound associated with them is the clicking of their feet while walking - a noise produced by a tendon slipping over the sesamoid bone in the foot.

Ask any child "What does a rooster say?" and they will throw their head back and give you all they've got! But the hens, they are a different story. They usually make a soft, contented clucking sound--until they lay an egg. Then they get very excited and proud and will squawk for a few moments and then settle back down. They do not make a ruckus in the morning like their male counterparts and they are fast asleep in their coop by the time the sun goes down. See similar questions...

MRI scanner is a specialised piece of medical imaging equipment that takes images of the internal structure of the human body. The MRI scanner will make cross-sectional images or 'slices' of the body and allow detailed pictures of the liver to be taken for the FerriScan Analysis. See similar questions...

Both the Institute, and the Victor Hugo Clinic, cannot make either a scanner or MRI. However, Dr Isabelle PIGEAU, radiologist who belongs to our team, can have a MRI Scanner or an artro-scanner made for you as soon as possible. See similar questions...

You will not be placed all the way into the scanner. However, depending upon the area being scanned, you will enter either head first or feet first. For example, feet, ankle, knee or leg MRI scans require you to go in feet first. All other scans, such as head, spine, shoulders, or torso require you to go head first. See similar questions...

Magnetic Resonance Imaging (MRI) generates cross-sectional images of the human body by using Nuclear Magnetic Resonance (NMR). The process begins with the positioning of the imaged body in a strong, uniform magnetic field, which polarizes the nuclear magnetic moments of water protons by forcing their spins into one of two possible orientations . Then an appropriately polarized radio-frequency field, applied at resonant frequency, forces spin transitions between orientations . See similar questions...

Yes. You can run xscanimage, the front end to SANE (Scanner Access Now Easy), either as a GIMP extension or in stand-alone mode. This supports Mustek and HP flatbed scanners, as well as the Connectix color QuickCam camera. See similar questions...

Yes, you can have an MRI done safely and effectively with no ill side effects or diagnostic problems. However, you should inform the physician performing the MRI procedure that you have permanent cosmetics. Since the micropigment contains iron oxide, this metallic substance can interfere with the electromagnetic fields used in MRI procedures. To avoid a potential problem, technologists use gel filled goggles, or a cream, to cover the area where iron oxide is implanted. See similar questions...

Based on our experiences in the field, the belt is likely to have been over-tensioned during installation. The belt may not be tensioned to the tension level recommended by the OEM service manual. If noise continues after retensioning, drive back to the workshop for diagnosis. See similar questions...

If you have a pacemaker, you should not be imaged because the pacemaker may be damaged in the magnetic field of the scanner. If you have metal filings, shrapnel, or ferromagnetic clips or pins in your body, you probably will not be imaged because these objects could be twisted by the magnetic field and cause serious injuries. Most new surgical metal implants are made of a high quality stainless steel which is non-magnetic. You can be imaged with these. Dental fillings and bridgework are okay. See similar questions...

Yes. Since our MRI scanners are open, there is ample space for someone to accompany you into the scanner room, even hold your hand during the scan. Warning: The person accompanying the patient will be exposed to the scanner's magnetic field just as the patient is, so please make sure it is safe for the visitor to be there.
