Brain spect resonance imaging (spect rography)

Sysysive resonance imaging (MRC) is a technique that uses a field and RF waves to determine the concentration of metabolisms in living tissue. Accordingly, brain sysys often use metabolisms containing P, Na, K, C, N, F to assess the concentration of metabolisms to be obtained spectrum with the corresponding peaks being concentrations of substances in the survey area.

Sysular Resonance (MRC) is a technique that uses fields and RF waves to determine the concentration of metabolisms in living tissue.

In fact, the word resonance (MRI) routinely uses H+ protons in water for forming, while sysyton resonances use metabolisms containing P, Na, K, C, N, F to assess the concentration of commonly obtained, sysytonic substances with the corresponding peaks being concentrations of substances in the survey area. The course of pathology involves a change in these metabolisms.

The basic steps in the sysymable resonance survey are measuring sampling, positioning the measurement area, selecting pulse sequences with TE time, the right volume block, and receiving the spectrum. The result of sysymable resonance is analyzed into a sysy chart line. Each vertex of the spectrum is characterized by frequency, height, width and area, height or area of the area below the vertex that symbolizes the relative concentration of the metabolism. Each substance has a certain position on the spectrum, depending on the frequency of action. The basic metabolisms commonly recorded on the spectrum are choline, Creatine, NAA, Lactate.

The purpose of sysysy resonance is to assess the concentration of metabolisms and meaningful changes that diagnose pathology.

Specific metabolisms are as follows:

• NAA (N-Acetylaspartate): Is an index of the density and viability of axlas and neurons. NAA decreases in most cases of brain damage.
• Cr (Creatine): An index for energy metabolism in brain tissue. Cr decreases in brain tumors, infections, necrosis, acute scattered cerebral sclerosis …
• Choline: Is a phospholipid metabolism component and an index of tumor cell membrane growth. For hypertension in tumors, injuries, inflammation, increased osmosis pressure, loss of myelin …
• Lac (Lactate): Is an index of the processes of conversion of anebic sugars. Lac increases in the brain hydrocephalus, decreases or increases dyslexia, decreases cerebral oxygen, acute and semi-acute cerebral infarction, necrosis, cystic lesions, anesthlecysis, tumors, myelin loss, moma conversion disorders.

• Sysular resonance is a non-invasive technique that allows the evaluation of metabolisms in the tumor tissue, providing information about the composition of the tumor.
• Sysular resonance in which brain tumors include: a different diagnosis of tumor-in-the-u lesions, suggestive of hist histival nature. Distinguishes primitive and sub-cerebral tumors. Assess the spread of the tumor, the progress of the tumor, the response to treatment, determine the ideal location for a biosy.
• The accuracy of sysysymed resonance in the diagnosis of tumours and non-tumours is 95-100%. The main signs of brain tumors on the systo phonial resonance are increased choline, Cho/NAA, Cho/Cr, hyperlipidemia, lactate, decreased NAA, decreased NAA/Cr, decreased Cr.
• Differentive diagnosis of brain tumors and brain medochroma: when there is no NAA and Cr peak on the resymnant spectrum, there is no increase in the region that suggests brain medoction.
• The sensitivity, specificity and accuracy of sysular resonance in assessing the high and low malignanty of brain tumors were 100%, 86% and 96%, respectively. The chemicals used to assess the malice of tumours are Cho, lactate, NAA, CR, mI.
• Biosy location determination: Sysymoid resonance is capable of identifying regions with the highest For increase, the regions with the highest tumour activity at the bottom are ideal locations for bios bios.
• Sysymosis is used in evaluation of therapeutic response, determination of recurrent tumors, remnants earlier than routine from resonance, even if the patient has an improved clinical improvement, distinguishing recurrent tumors, remaining with non-tumor abnormalities after treatment. When Cho increases or has an increased Cho/NAA rate suggests a recurrence of the tumour.

• Setting pacemaker
• Had surgery to replace the heart valve (it has a metal composition).
• Carrying in person the material grafted from the word.
• Nerve sysicing machine.
• Automatic injection pumps implanted in humans.
• Foreign objects in the eyeball (in suspected cases, an electroetrosy picture is required and a specialist examination is required)
• Pairs of blood vessels in the skull.
• Do not use with pregnant patients in the first quarter.
• Other contrain specifying cases that need to be evaluated by filming:
• There are metal drains in the cavities in the body.
• Vascular Clips
• Fixed tooth welding material.
• The listener is attached to the eardrum.
• Artificial joints and osteodermic materials (screws, splints,…) do not have contrainctrainctraines but can damage the field of words and will not be able to be converted into images.

Step 1: Prepare

After being prescribed an MRI resonance imaging scan from the doctor, the patient moving to the imaging department will be greeted by the rem resonance imaging department staff and instructed to change, remove metal items on the body to ensure safety during the resonance imaging. Upon entering the shooting room, which is guided by the staff in a comfortable position suitable for the shooting unit, the bed will automatically move to the shooting area.

Step 2: Proceed

The technician will place the patient in the IRM machine. Usually the patient will be in a denture removal machine, deaf machine, glasses, jewelry, hair pair, shoes, belt, all that metal has in the bag (coins, pens, mobile phones, ATM cards …) will be required to leave.

The resonance imaging time will range from 40-60 minutes. The patient needs to try to lie still in a position to get the best information, without interference.

In some cases, a contrast injection from the reproflex room staff will place a small needle in the edge of the elbow area and the needle will be withdrawn at the end of the examination.

• Patients unaffected by radiation
• Patients are not biologically affected
• Differentive diagnosis of tumor-in-the-u lesions, suggesting hist histi histative nature. Distinguishes primitive and sub-cerebral tumors. Assess the spread of you. The progress of the tumor, in response to treatment, determines the ideal location for a biosy.

• The price is still high.
• Can not be used if the patient has claustrophobia, Claustrophobia
• Long scan time: Difficulty if the patient is severe or uns cooperative
• Patients cannot be photographed with pacemakers, surgical clips, eye or ear implants
• Resuscitation equipment cannot be brought into the shooting room.

Brain spectrum resonance is a technique that requires professionals to perform as well as a modern medical machinery system that can bring the best image quality for healing.

Share99 International Health Hub has applied res resonance techniques to medical examination and diagnosis. In particular, the brain resonance imaging technique at Share99 is carried out properly, in accordance with the process by a team of highly skilled doctors, modern machinery system, thus accurate results, contributing significantly to the identification of diseases and stages of disease, diagnosis and screening of cancer diseases. From there, give the most effective treatment regimen for patients.
