»MRI revealed changes in the level of water in the body exposed to disease

Diagnostic techniques provide an accurate picture of the magnetic resonance of the members of both the image acquisition scan of the various layers of the member, or a three-dimensional image. The technology has replaced the traditional painful methods of diagnosis.
And magnetic resonance imaging depends on the fact that the body is composed of two-thirds of the water. And doing a lot of diseases, to change the amount of water in different parts of the body, and this is captured in photos, Fadtrapat such as brain tumor or hemorrhage or inflation, leading to minor changes in water content in brain cells, which is captured in CT images.
Magnetic resonance imaging was essential to prepare the patient for surgery, it allows doctors to determine the exact location of any damage. Photo and precise enough to allow placements of electrodes in the brain cells for the treatment of central pain, or movement disorders, such as patients with Parkinson's.
Using modern technology called the «functional Magnetic Resonance» enable doctors to identify the parts of the nerves the brain responsible for pain and those treating the information or those that interact with the jokes for example, in addition to monitoring small changes in the brain sections of the left and right.
And magnetic resonance imaging reveals the exact size and location of tumors, making surgery and radiation treatment more precise. It also allows to distinguish between different tissue types. In colon cancer, it helps to determine how deep into the tissue to within one millimeter. It also enriches the MRI on the telescope, in many cases, the suffering of the patient Viafee introduction of perspectives in the channels of the pancreas or gall bladder for example. It has also dispensed with the introduction of endoscopic tools in the joints in many cases.
»Faster Tomowerev of magnetic resonance in the world, examines the whole body in 12 minutes

Launched «Siemens» German new generation of devices Tomowerev
(Body CT scan) magnetic resonance look deeper and faster in the human body, does not require the examination of the body waves. And carries the name of the «Magnetum Aphanto» The company says that the fastest of its kind in the world. According to Dr. Christian Clesp Hospital Charité Berlin, who tested the device, that «Magnetum Aphanto» superior hardware in terms of speed on the lack of damage inflicted tissue damage compared to normal-ray machines. Clesp said that the secret lies in the speed of the technology «Total Image Matrix Technology» «Total Image Matrix Technology» TIM which quickly reminds «New» hero of the film Matrix.
The system can examine the 2.5 meters of the human body during the 12 minutes. And do it once without the need for the ball, and send pictures of all the organs of the body, including tissues, which disappear from the bone easily.
Clesp spoke about the effectiveness of a superior «Magnetum Aphanto» in cases of detection of breast cancer in women. And already researchers from the University of Bonn Medical conducted a study that compared the effectiveness of conventional radiation, and Almamugrav Tomowerev and MRI in early detection of breast cancer. The study included hundreds of women at risk of the disease and demonstrated superiority of a magnetic resonance heavily on other types of diagnosis in terms of speed of early diagnosis and detect smaller tumors «silent» in the breast.

»What do you know about MRI

* MRI: --
Research has begun to MRI in the early seventies.
user posted image and began to apply to patients in 1980 and was also cleared through the food and medicine in 1984, and since then began to expand its use even at the magnetic resonance imaging devices to more than ten thousands of machines in the world, which is the best way to medical imaging examinations in the following :


1 - brain, blood vessels of the brain, inner ear.
2 - the neck, shoulder, neck paragraphs, the blood vessels of the neck.
3 - Heart, Aorta and coronary arteries.
4 - paragraphs or chest pain.
5 - the highest stomach, liver, kidney, spleen, pancreas and blood vessels of the abdomen.
6 - pelvis, hip, male genitalia and female, the bladder.
7 - Central musculature (shoulder - knee - arm detail - detail to ankle and foot), thanks to show the contrast between tissue density in close proximity.

* Some of the questions examined by magnetic resonance:

1 - Are you pregnant or potentially pregnant to you?
2 - Are you allergic to any medications?
3 - Is skull surgery?
4 - Do you have heart surgery?
5 - What kind of surgery I had?
6 - Is surgery joints or change the key?
7 - Is there an industrial objects within your body?
8 - Do you put a pacemaker?
9 - Do the intravenous catheter?
10 - Do the heart valves?
11 - Do you love a screw (and a spot against reproduction)?
12 - Do the incentives nervous?
13 - Do the industrial joints?
14 - Do the bolts or pillars?
15 - Is there a surgical pins?
16 - Is there a tattoo?
17 - I Will by shrapnel or bullets?

In case of doubt in the presence of a metal object body scan could be done to determine the feasibility of a normal magnetic resonance work.

Must also to take off his clothes and the patient wears a light dress and leave a special examination of any patient with metal objects such as:
1 - jewelry and clock.
2 - pins (pence) hair
3 - the keys and coins.
4 - glasses.
5 - Means of hearing.
6 - mobile dentures.

* Moves the magnetic resonance imaging examination:

1 - you need some more tests to dye injection or intravenous fluids on the road.

2 - put the patient on a table in the examination required by the technical ray, as well as proof of a surface to be photographed as a member.

3 - The X-ray and examination, as well as could be authorized to plug in the case of the sound of the alarm of the device.

4 - After the end of the examination the patient waiting for a brief period until the review of the resulting images.

* What happens during the examination?

1 - Transfer by the attending physician at the center of inquiries of appropriate medical imaging and to make sure that before the date of the examination by a phone call.

2 - Reception: data from the patient and the old tests.

3 - to clarify the method of examination.

4 - preparation for the examination: nature or taking intravenous fluids before the tests.

5 - check, must be adhered to:

Full tranquility and relax - listen to *****s during the test (breath-holding) - The question if necessary.

6 - Waiting for a brief period after the screening to ensure the integrity of images or pictures to complete some additional testing if necessary.



* How does the magnetic resonance examination system?

MRI uses magnetic energy and radio waves to produce cross-sectional images of the human body.

System consists mainly of a large cylindrical tube is (in some cases, the letter C Oually another form of the tube open).

Measured strength of the unit, called the six power devices, ranging from half to one and a half in most organs of the six open-resonance force ranging between 0.01 to 0.35 Tesla magnetic field and the strength of 1.5 Tesla in the system are estimated at 30 times the weakening of the gravity of the introduced ranges between 55 to 65 cm in length and between 160 to 260 cm, 3% of patients complain of fear of enclosed spaces and can not conduct the examination, especially in closed devices.

Examination consists of 2 tones: 6 parts of every part of it takes between 2: 15 minutes depending on the device used and the quality of the examination.

During the inspection indication to close the radio and exports transit through a particular object can be measured by a resonance and transferred to the CT image. The tests can be done in the horizontal and vertical sections in two ways and one is divided to the left of the body and the right and the other to the back and front clips can also work in italics, especially for device nicknamed.

* Applications and advantages of magnetic resonance imaging:

One of the most important features of the examination not to be subjected to X-ray, as is the case in the traditional and the regular X-ray scan your computer. It is also given to the examination of highly varied between tissues and blood vessels without ionizing character or wounding the body.

At the beginning, it is the magnetic resonance examination of the brain, vertebrae, which was about a hour and then have tests to check the joints - the blood vessels - heart - breast, as well as some parts of the abdomen - the pelvis and increased the speed of the examination to be about 10 minutes in some traditional tests.

* Some tests by modern magnetic resonance imaging:

1 - examinations of blood vessels.

2 - The functions of the body (brain, heart muscle).

* Some of the modern magnetic resonance:
- Short-wide devices.
- Open devices.
- Devices in the form of C (open from one side).

* Some of the questions that ask about the many MRI:

1 - Does the examination of the damage? There is no pain and feel the examination of some people to get a place in the examination, as well as the dye used in the examination do not lead to any complications.

2 - What time it takes for examination? Depends on the type of inspection, and take between 15: 45 minutes.

3 - Why make the voice of ways during the examination? Issued as a result of the opening and closing of the components within the device and can be overcome by using a plug authorized.

4 - Can be done before the regular-ray examination? Magnetic field can pull the metal parts that can be at times to make sure it does not exist in the body of work before the examination.

5 - May affect the examination in dental fillings? Does not affect the examination in dental fillings, but can cause some confusion in the picture.

6 - Does affect dental examination in the pillars? Can also cause some distortion of the image.

7 - Is the whole body is inside the body? Yes, but be part to be examined in the center of the device.

8 - Can I movement within the machine? No, but some parts could be modified, which have not been photographed, and in the periods between each part of the screening tests as well as requiring some breath-holding for a short period.

9 - Can I talk during the examination? Yes, you can talk to and ask him what the technical parts of the examination when the roads.

10 - Can I accompany a friend or relative within the examination room with me? Each of the centers of the disposal of a particular resonance in this regard. But there is no damage after he was certain to be free of metal objects with it.

11 - Do I need to dye injection during the examination? This view depends on the Radiologist and the treating physician who determine the need for before or during the examination.

12 - How is the injection of dye during the examination? Is injected through the intravenous injection.

13 - Can I breast-feed the child after an injection? Prefer to postpone until after the breast 24 hours of testing and can be drained, and the maintenance of breast milk before the start of the examination to be used after that.

14 - Can I work during the pregnancy test? Screening examination is safe, but available information on it is great why he does not work check in the first third of pregnancy, as well as its work only when necessary in the remaining term and to try to reduce the time of the inspection and indispensable in the event there is no alternative to consult the radiologist.

* Magnetic resonance examination of the breast:

In 1991 was the adoption of breast MRI in the diagnosis by examining the Assistant Ouramh addition to the regular X-waves. Good advantage in the diagnosis of breast Industrial and surrounding tissues that are not reflected in the regular-ray, as well as in determining the degree of development and spread of cancer ... And can be made for those who are more vulnerable to the risk of breast cancer before 40 years, the difficulty of diagnosing regular mammograms at this age. Further examination is the only approved Kmsh for women who do not complain of any symptoms (breast tumor inhabitants).

* Information about the examination:

1 - take between 30: 60 minutes (may require more time).
2 - The cost of the examination resonance several times more expensive than the regular ray examination.
3 - Use of character.
4 - Some patients complain of fear of enclosed spaces.
5 - sometimes does not differentiate between tumors and other tumors.
6 - need a sample for proper diagnosis.
7 - is not in most places.
8 - can not diagnose Altklsat.

* Magnetic resonance characteristics of the breast:
1 - Breast Screening industrial.
2 - sensitive to small changes.
3 - breast examination, which has high density (less than 40 years).
4 - the spread of the diagnosis of breast tumor.
5 - to determine the appropriate surgery for breast cancer (mastectomy or tumor only).
6 - Identification of the breast cancer decline.
7 - the diagnosis of inverted nipple.
8 - Identification of the first tumor and the presence of lymph glands Balibt inflation.
9 - early identification for those with risk factors of breast cancer.
