Magnetic resonance cholangiopancreatography or MRCP uses a powerful magnetic field, radio waves and a computer to evaluate the liver, gallbladder, bile ducts, pancreas and pancreatic duct for disease. It is noninvasive and does not use ionizing radiation. Tell your doctor about any health problems, recent surgeries or allergies and whether there’s a possibility you are pregnant. The magnetic field is not harmful, but it may cause some medical devices to malfunction.

Most orthopedic implants pose no risk, but you should always tell the technologist if you have any implanted devices or metal in your body. Guidelines about eating and drinking before your exam vary between facilities. Unless you are told otherwise, take your regular medications as usual. Leave jewelry at home and wear loose, comfortable clothing. You may be asked to wear a gown.

If you have claustrophobia or anxiety, you may want to ask your doctor for a mild sedative prior to the exam. Magnetic resonance cholangiopancreatography MRCP is a special type of magnetic resonance imaging MRI exam that produces detailed images of the hepatobiliary and pancreatic systems, including the liver, gallbladder, bile ducts, pancreas and pancreatic duct.

Magnetic resonance imaging MRI is a noninvasive test doctors use to diagnose medical conditions. MRI uses a powerful magnetic field, radiofrequency pulses, and a computer to produce detailed pictures of internal body structures.

MRI does not use radiation x-rays. You may be asked to wear a gown during the exam or you may be allowed to wear your own clothing if it is loose-fitting and has no metal fasteners. Guidelines about eating and drinking before an MRI exam vary at different facilities. Usually, you will be instructed not to eat or drink anything for several hours before your procedure. Because your procedure may require use of contrast material that is swallowed or injected into your bloodstream, the radiologist or technologist may ask if you have allergies of any kind, including allergies to food or drugs, hay fever, hives or allergic asthma.

However, the contrast material used for an MRI exam is based on gadolinium and does not contain iodine. A gadolinium contrast agent is less likely to cause an allergic reaction compared to the iodinated contrast agents used in CT scanning.

The radiologist should also know if you have any serious health problems and what surgeries you have undergone. Some conditions, such as kidney disease, may prevent you from having an MRI with contrast material.

Women should always tell their doctor and technologist if they are pregnant. MRI has been used since the s with no reports of any ill effects on pregnant women or their unborn babies. However, the baby will be in a strong magnetic field. Therefore, pregnant women should not have an MRI in the first trimester unless the benefit of the exam clearly outweighs any potential risks.

Pregnant women should not receive gadolinium contrast unless absolutely necessary. If you have claustrophobia fear of enclosed spaces or anxiety, ask your doctor to prescribe a mild sedative prior to the date of your exam. Leave all jewelry and other accessories at home or remove them prior to the MRI scan. Metal and electronic items are not allowed in the exam room. They can interfere with the magnetic field of the MRI unit, cause burns, or become harmful projectiles.

These items include:. In most cases, an MRI exam is safe for patients with metal implants, except for a few types. People with the following implants may not be scanned and should not enter the MRI scanning area without first being evaluated for safety:. Tell the technologist if you have medical or electronic devices in your body. These devices may interfere with the exam or pose a risk.

Many implanted devices will have a pamphlet explaining the MRI risks for that device. If you have the pamphlet, bring it to the attention of the scheduler before the exam.

MRI cannot be performed without confirmation and documentation of the type of implant and MRI compatibility. You should also bring any pamphlet to your exam in case the radiologist or technologist has any questions. If there is any question, an x-ray can detect and identify any metal objects. Metal objects used in orthopedic surgery generally pose no risk during MRI.

However, a recently placed artificial joint may require the use of a different imaging exam. Tell the technologist or radiologist about any shrapnel, bullets, or other metal that may be in your body. Foreign bodies near and especially lodged in the eyes are very important because they may move or heat up during the scan and cause blindness. Dyes used in tattoos may contain iron and could heat up during an MRI scan.

This is rare. The magnetic field will usually not affect tooth fillings, braces, eyeshadows, and other cosmetics. However, these items may distort images of the facial area or brain.

Tell the radiologist about them. Your child may need to be sedated in order to hold still adequately during the procedure. If this is the case, you will be given instructions for your child about not eating or drinking several hours prior to sedation and the examination.

For the safety of your child during the sedation, it is important that you fully understand and follow any instructions that have been given. After the procedure there will be a recovery period from the sedation.

The traditional MRI unit is a large cylinder-shaped tube surrounded by a circular magnet. You will lie on a table that slides into a tunnel towards the center of the magnet. Some MRI units, called short-bore systems , are designed so that the magnet does not completely surround you. Some newer MRI machines have a larger diameter bore, which can be more comfortable for larger patients or those with claustrophobia.

They are especially helpful for examining larger patients or those with claustrophobia. Open MRI units can provide high quality images for many types of exams. Open MRI may not be used for certain exams. For more information, consult your radiologist. Instead, radio waves re-align hydrogen atoms that naturally exist within the body. This does not cause any chemical changes in the tissues. As the hydrogen atoms return to their usual alignment, they emit different amounts of energy depending on the type of tissue they are in.

The scanner captures this energy and creates a picture using this information. In most MRI units, the magnetic field is produced by passing an electric current through wire coils.

Other coils are inside the machine and, in some cases, are placed around the part of the body being imaged. These coils send and receive radio waves, producing signals that are detected by the machine. The electric current does not come into contact with the patient. A computer processes the signals and creates a series of images, each of which shows a thin slice of the body.

The radiologist can study these images from different angles. MRI is often able to tell the difference between diseased tissue and normal tissue better than x-ray, CT, and ultrasound. The technologist will position you on the moveable exam table. They may use straps and bolsters to help you stay still and maintain your position.

The technologist may place devices that contain coils capable of sending and receiving radio waves around or next to the area of the body under examination. MRI exams generally include multiple runs sequences , some of which may last several minutes.

Each run will create a different set of noises. If your exam uses a contrast material, a doctor, nurse, or technologist will insert an intravenous catheter IV line into a vein in your hand or arm.

They will use this IV to inject the contrast material. You will be placed into the magnet of the MRI unit. The technologist will perform the exam while working at a computer outside of the room. You will be able to talk to the technologist via an intercom. If your exam uses a contrast material, the technologist will inject it into the intravenous line IV after an initial series of scans. They will take more images during or following the injection.

The actual MRCP exam takes approximately minutes, but it is often performed with a standard MRI of the abdomen, which may last approximately 30 minutes and involves the use of contrast material.

In this case, the entire examination is usually completed within 45 minutes. Most MRI exams are painless.

However, some patients find it uncomfortable to remain still. Others may feel closed-in claustrophobic while in the MRI scanner. The scanner can be noisy. If contrast material is used, there may be brief discomfort during initial placement of the intravenous catheter line.

The oral contrast used at some institutions may have an unpleasant taste and cause temporary fullness, but most patients tolerate it well. It is normal for the area of your body being imaged to feel slightly warm.

If it bothers you, tell the radiologist or technologist. It is important that you remain perfectly still while the images are being taken.

This is typically only a few seconds to a few minutes at a time. You will know when images are being recorded because you will hear and feel loud tapping or thumping sounds. The coils that generate the radio waves make these sounds when they are activated.

You will know when images are being recorded because you will hear and feel loud tapping or thumping sounds.

The coils that generate the radio waves make these sounds when they are activated. You will be provided with earplugs or headphones to reduce the noise made by the scanner. You may be able to relax between imaging sequences.

However, you will need to keep the same position as much as possible without moving. You will usually be alone in the exam room. However, the technologist will be able to see, hear, and speak with you at all times using a two-way intercom. Many facilities allow a friend or parent to stay in the room if they have also been screened for safety. Children will be given appropriately sized earplugs or headphones during the exam.

Music may be played through the headphones to help pass the time. MRI scanners are air-conditioned and well-lit. In some cases, IV injection of contrast material may be given before the images are obtained. The IV needle may cause you some discomfort and you may experience some bruising. There is also a very small chance of skin irritation at the site of the IV tube insertion. Some patients may have a temporary metallic taste in their mouth after the contrast injection.

If you do not require sedation, no recovery period is necessary. You may resume your usual activities and normal diet immediately after the exam. On very rare occasions, a few patients experience side effects from the contrast material. These may include nausea, headache, and pain at the site of injection.

It is very rare that patients experience hives, itchy eyes, or other allergic reactions to the contrast material. If you have allergic symptoms, tell the technologist.

A radiologist or other doctor will be available for immediate assistance. A radiologist, a doctor trained to supervise and interpret radiology exams, will analyze the images. The radiologist will send a signed report to your primary care or referring physician, who will share the results with you. High-quality images depend on your ability to remain perfectly still and follow breath-holding instructions while the images are being recorded.

If you are anxious, confused or in severe pain, you may find it difficult to lie still during imaging. A person who is very large may not fit into certain types of MRI machines.

There are weight limits on the scanners. Implants and other metallic objects can make it difficult to obtain clear images. Patient movement can have the same effect. A very irregular heartbeat may affect the quality of images.

This is because some techniques time the imaging based on the electrical activity of the heart. MRI is generally not recommended for seriously injured patients. However, this decision is based on clinical judgment.

This is because traction devices and life support equipment may distort the MR images. As a result, they must be kept away from the area to be imaged. Some trauma patients, however, may need MRI. Present data show no convincing evidence that non contrast MRI harms the fetus of a pregnant woman.

However, if the need for the exam is not time sensitive your doctor may delay the exam until after delivery. P abbreviations with the community: 0 Comments. Notify me of new comments via email. Cancel Report.
