1. MRI in the Medical centre of oncology and radiosurgery Cyber Clinic of Spizhenko
Quite recently exactly in the Medical centre of oncology and radiosurgery Cyber Clinic of Spizhenko the only in Kyiv MRT of such high quality ( Toshiba 1,5 Tesla Vantage Atlas) is installed. MRT in Cyber Clinic of Spizhenko allows to conduct the full specter of diagnostic magnetic-resonance images with a unique ability of receiving diffusion-weighed images of the whole body (PET analogue); however, it has no radiation load over patient.

2. Magnetic-resonance imaging
Magnetic-resonance imaging is one of the cancer diagnostics methods. It is the method of receiving images which are induced by the signal of nuclear magnetic resonance. The difference between magnetic-resonance imaging from computer tomography lies in the fact that in case of applying MRI the nucleus magnetization of a particular type in defined volume element is regarded as the measured quantity, when in case of CT—it is the coefficient of X-ray absorbing by different biological tissues. The clinical usage of MRI method lies in examining of the spatial distribution in the human body of nucleus of hydrogen, phosphorus and some other elements. The main quantity, registered in the MR-examination, is the reaction of magnetic nucleus to the influence of changeable magnetic field, which depends on the nucleus’ density and other characteristics, specific for each area of the body.

FAQ (frequently asked questions) about magnetic-resonance imaging (MRI)

Where is magnetic-resonance imaging made in Kyiv? You may go through the magnetic-resonance imaging in Kyiv medical diagnostic centers, including center of oncology and radiosurgery Cyber Clinic of Spizhenko.

2.The doctor advised me that I should make CT or MRI. I don’t know what to choose, could you recommend me what is better? In general, the diagnostics method choice is the doctor’s prerogative. The best thing is if the examination is defined by your doctor who knows you personally and who conducted the prior anamnesis gathering. You can receive free telephone consultation of doctors at the Medical Centre of oncology and radiosurgery “Cyber Clinic of Spizhenko”.

3. Do I need some preparations before the magnetic-resonance imaging (MRI)? Are there any contra-indications for MRI?

• Do not forget to bring your previous images of CT, MRI, X-Rays, ultrasonic scanning results, if you have them!
• Claustrophobia—fear of closed space.
• You should measure the weight of patient and his\her size\volume of chest.
• It is forbidden to bring metal staff (clock, coins, credit cards, cell phones, etc) to the room where the magnetic-resonance scanner is located as far as powerful scanner magnet may damage them, and the received images would have a low quality because of the magnetic field deviation.

However, it is required to remember that there are certain contra-indications for the MR-scanning. Because of the strong tomograph magnetic field, in the majority of the cases the MRI is forbidden for those patients who have implanted metal in the body (bone implants, implanted heart simulations, shell fragment etc). for more detailed discussion of this issue it is required to consult with our specialist oncologist at our medical centre.

Preparation to the Magnetic-resonance imaging: MRI of the abdominal cavity and organs of a small pelvis: it is required to abstain from food and drink for 5 hours before examination. Usually there is no special preparation for MRI of other organs.

4. Contrasting substance when MRI examination In the majority of the cases the contrasting substance when undergoing the MRI-examination is not required; however, in some cases the MRI-examination cannot be performed without this substance. This substance is given through the catheter; no unpleasant feelings occur.

5. Pregnancy and MRI If the patient is pregnant or is likely to be pregnant, she should necessarily inform the doctor, conducting the examination.

MRI is much safer than CT and X-rays, as far as during this method the ionizing radiation (X-rays) is not used. However, MRI provokes some body heating, that’s why MRI is not preferable during first three months of pregnancy. During the second and third trimester of pregnancy MRI is regarded safer; however, if there is a possibility to delay the scanning till delivering a baby, than it is preferable to wait till the end of the pregnancy. MRI-contrasting substance is contra-indicated for the pregnant.

6. What is magnetic-resonance imaging (MRI)? Magnetic-resonance imaging (MRI) or nuclear-magnetic resonance (NMR) is the new method of receiving images of inner organs without the use of X-rays and without radiation. MRI-scanner receives the images, made on the basis of magnetic fields, generated by the human body. MRI “sees” soft tissues (muscles, nerves, brain, ligaments etc). In the majority of the cases, only MRI can receive diagnostic image, needed for the appropriate treatment choice.

7. What is the difference between computer tomography (CT) and magnetic-resonance imaging (MRI)? Both these examinations allow the doctor “look inside the organism” of a patient; however; there are some important differences between them:

• According to the action principle;
  
• According to the sensibility (which tissues are seen better)

Action principles.

In order to receive images the computer tomograph uses X-rays. Computer tomograph is a specific X-ray apparatus, which moves around the patient’s body and shoots images from different angles. Then the images are worked up and summed up by the computer.
In order to get the images the magnetic-resonance tomograph (MRT) does not use X-rays. The patient is placed into strong magnetic field. It leads to the thing that all the hydrogen atoms in the patient’s body are set in parallel to the direction of magnetic field. At this moment the apparatus sends electro-magnetic signal in perpendicular direction to the main magnetic field. The hydrogen atoms, which have the same frequency as s signal has, generate its signal, detected by the apparatus. Different tissue types (bones, muscles, vessels etc) have different amount of hydrogen atoms and that’s why they generate signal with diverse characteristics. The tomograph detects its signals, decodes it and builds the image.

For which tissues and organs CT is better, and for which MRI is better?

CT: If to examine the usual X-ray scanning, than even non-specialist scan would be the best variant for bones scanning. Moreover, CT with the use of “X-Rays” is better for the bone structures. That is why CT is ideal for diagnostics of bona damages and traumas. Besides, the new hemorrhage is better seen via CT scanning, thus, CT is used for examination of patients’ with diseases and traumas of head, chest, abdominal and pelvis cavities, and cerebral accidents at their early (!) stages. The use of contrasting substance allows to receive a high-quality image of vessels, kidneys and intestines.

MRI: When examined via MRI, the bones are also seen; however, soft tissues are seen much better (cartilage, muscles, brain etc). MRI is regarded as one of the best methods for joints’ examination. That’s why MRI, for example, is preferable when there is suspicion on damage of ligaments and in order to exclude hernia of spine disks. There is an expanded use of MRI in neurosurgery and neurology (old traumas of brain, cerebral accidents at their (!) late stage, suspicion on tumors of spinal cord and brain etc), traumatology, urology, endocrinology, gynecology, surgery of bile-excreting. Conduction of cholecyst cholangio graphy via MRI substitutes the diagnostic operation—retrograde cholecyst cholangio graphy, which the patient badly undergoes.

9. How does the examination go on? During the scanning conducting the patient is located in an open space of the apparatus. It is very important that a patient does not move during the examination, because even the smallest movement may reduce the quality of the received images. From all the sides of the scanner there is a sufficient light and there is also a fan, which provides the patient with the fresh air.

10. How long is the examination? The examination lasts from 30 to 90 min.
It is forbidden to bring metal staff (clock, coins, credit cards, cell phones etc) to the place where the scanner is located as far as this magnet may damage the named staff, and the received images would be of a low quality because of the magnetic field deviations.
Before the start of the examination the patient is necessarily questioned regarding the presence of metal implants, pace-makers etc in the body.
