Contrast media is a medium which is injected into human body. It injected through the catheter or mouth to make the radiography image on film become contrast and easier to look which is harder to made by using x-ray film. Moreover, it has some properties that cannot be penetrate by radiation or can be penetrate by radiation. It called contrast agent.
TYPES OF CONTRAST AGENT
Two types of agent contrast or two ways giving contrast agent to a patient. For an example, a radio fluid and the air in the urinary bladder of the patient.
Same like the contrast media's agent which is a medium which used in radiography process to make the image in the human body structure become clear to look.
It also called contrast agent or contrast medium.
Contrast medium which is not a radio metal such as air and carbon dioxide.

The pattern that produced by contrast agent. For example, the damage on urinary bladder caused by contrast agent.
Using the contrast medium which are radio metal such as barium sulphate and iodine production.
Using three contrast media or flow the contrast agent to some patients for some of the time.
AIR SOLUTION CONTRAST AGENT
Contrast agent that be used for injected into the vascular system which are pure visual or organ or viewing the alignment at the digestive system. Before this, got preparation of iodine is dangerous and can cause and create the damage to the tissues. So, it must be injected by intravenous way. But, nowadays, our world became modern and more up to date for the machines and medication researches. Production of water iodine solution that not dangerous are more helping us. Furthermore, it used in myelography process. Imaging diagnosis and therapy also up to date. Moreover, they not only limit to the levels on equipments and techniques but got the side of pencelup which is used. A pencelup or contrast medium is a fluid medium which is used in a radiology examination for a purpose to view internal structures or some organs that been researched. This is the only way to do it. Contrast medium can be inserted into the human body through inject which is through the veins, arteries and lymphatic, through the mouth or from below which is rectum.
Three types of contrast media:
1. Iodine contrast medium which is injected. It also can be given by through the mouth.
2. Barium sulphate which is gave through the mouth or through the rectum.
3. Gadolinium that be injected.
Contrast media is productive when it through one of the ways. When a contrast medium is injected, contrast media will make the vessels and the organs with good blood supply look clear or white on the radiography image or radiography film.
So, in the angiography examination, pembuluh-pembuluh will look like thick or clear when exposed by radiation. Other than that, for the computerize of a tomography, pembuluh-pembuluh and organs with some good blood supply will become clear ang good - looking. After that, contrast medium will be digested by two of kidneys. So, in urography intravene, flow of the urinary system will become clear and good - looking on the radiographic image or radiographic film. By using the way, many types of organs or many types of structure can be viewed and learned for some lessons.
When the contrast medium been giving through the mouth in barium pattern, the stomach will become clear and white - looking on the radiographic image or radiographic films or x - ray films. It also become samething if the contrast medium give through rectum in the enema barium pattern, the colon will be looked clear or white - looking on the radiographic image or radiographic films or x - rays films. So, the structure of the colon can be studied easier.
Gadolinium is a contrast medium which is can be give by injected during magnet resonance. Furthemore, contrast medium acts such pembuluh-pembuluh and organs with the good blood supply will view the white - looking on MRI images.

The modern intervene contrast media can be blocked by the many of patients and quickly wasted from the human body and got no bad side effects. Other than that, contrast medium contains iodine that can cause a hot feeling when injected. Sometimes, it can be sudden and cause the nausea. So, it is advised to not take some food before any radiology examination that requires contrast media. Sometimes, contrast media that contain the iodine which can cause the allergic to some patients.
Moreover, contrast media that contain the barium sulphate is not danger. Barium sulphate will be digested out from the human body in one or two days. Furthemore, contrast media which is contain the gadolinium cause and give some side effects sometimes.
In all of the case, using the contrast media on the pregnant women are not advised for using the contrast media because of less of informations and justice which are confirmation for safety in using the contrast media. Otherwise, if the examination can save the lives, the risks must be consider for each case.
CONTRAST MEDIA INTRAVASCULAR (THROUGH VEINS AND ARTERIES) IN RADIOLOGY (REFERRED TO THE CONTRAST MEDIA THAT CONTAIN THE IODINE)
Patients very need the contrast media in the radiology examination because of the researches in radiology that show the patients need and require the contrast media giving into their body through the veins or arteries. For the example is intervene urogram. There are two types of contrast media. One of them is containing iodine and the other one is ionic and not ionic.Usually, only the bones and air will view on the radiographic image or radiographic films. So, to make some different the flow of urinary or blood in blood pembuluh, contrast media that contain the iodine will insert to improve the density of urinary or blood. After that, it will view white - looking on the radiographic image or radiographic films like bones on the x - ray films.
If the patients have one of the situations below, they need to fast (cannot eat and drink) in the range of time four until six hours before do the examination.
If the patients show any of the symptoms, they must be care and take the precaution for their safety when do the special examination and realize the additional risks:
known allergic history
reaction with the contrast media before
reaction to the medicine before
Mieloma Multiple or syndrome myelodysplastik or chronic diabetic (don't decrease your drink)
Very old (> 65 years old) and very young < 6 months>
If the patient has some allergic or reaction before, the patient is advised to take a prednisolone 40 milligram for twelve hours before and 40 milligram for two hours after the examination. However, examination requires need to compare with the risks. The doctor usually will suggest the examination. So, if the patient is not sure about the risks factors, please tell the doctor for the details of the information about the any allergic or medication situation.For the Mieloma Multiple patient or myelodysplastic syndrome, the patient need to drink sufficient water to avoid the dehydration although for the examination like intravenous urogram.The intravenous contrast media that used for the patients like the above must be contrast media non - ionic usually.If the patient is a patient that has diabetics or taking Glucophage (Metformin), please to stop the medication in a range of time about forty eight hours before examination that require intravenous contrast media injection or intra-arterial.
PROBLEM OR COMPLICATION THAT MAY HAPPENS
Although there are information about that things below, probability about the reaction that reasonable to the chronic reaction is too low. Of course the doctor compare the advantages and the risks when he suggest some types of examinations for the patients. Besides that, it will be more risks to cross the road if compare to do the examination that help to diagnose the precise and correct situation.
Contrast media is such a type of other medicine that you know. Actually, new contrast media is safe but like the other medicine including the medicine that you take often like panadol or paracetamol. Besides that, contrast media has a reaction potential that you do not like. So, it is classified as a low, middle n chronic. With the non - ionic contrast media, probability the reaction that will happen is too low. Majority of the reaction are weak, temporal and not need any treatment and happen in first twenty minutes after injection. However, there are minority of the late reaction that can happen first day or second day after the injection.

The example of reaction of somebody to the medicine of the contrast media including:
Weak reaction category:
Nausea, vomit or both.
Feeling hot at all of the body part (feel like after exercise).
Temporally itchy or continuously. Can take the antihistamina medicine.
Situation like get a flue.
Middle reaction category:
Hard to breath like asthma. Emergency treatment must be given. Usually the situation are not attack the human lives.
Hypotension: blood pressure that decrease suddenly and emergency treatment must be given quickly. Usually it not attacks the human lives.
Chronic reaction and attack the human lives:
Not attack human lives very frequently with the new non - ionic contrast media.
Chronic reaction that cannot be predictable. (Anaphylactic shock)
WHAT YOU SHOULD DO AFTER GOT INTRAVENOUS CONRAST MEDIA?
It depends on the procedure which is chosen.
Generally, you are advised to drink a lot of water and make sure your body dehydration. Usually, contrast media will flow out through the urinary system after four hours.
DISCUSSION ABOUT THE CONTRAST MEDIA.
Question: are those any patients got allergic reaction of bad side effects to the gadolinium fluid, MRI contrast media agent and are they can give side effect for a long term?
Answer: such the other contrast media fluid, they only give the side effect to the patient who has an allergic to the contrast media and the medium which has iodine. The case like this happened at 1969 where a patient almost dead caused by IVP fluid. The best way to avoid the problem like this is realization of the patient herself or himself. The patient must tell the doctor or any specialist who are involve if the patient get some problem or allergic. Furthermore, the problem can be the long term problem to the patient because the same patients ask for the treatment for the chronic illness at the spinal cord and the vertebrae. After do the examination, it is caused by the contrast media.
Question: what are the examples of the medium that be used in contrast media and what are the function?
Answer: the medium of the contrast media is chemical medium that be used to increase and improve visualization and visibility of the internal structures for a diagnosis imaging in medication field. However, the medium of the contrast media is used to the imaging diagnosis with the x - ray to increase and improve the attenuation of x - ray which is positive contrast medium that will talk here or decrease the attenuation x - ray which is negative contrast media with air base or gas. Other than that, contrast medium also is used in MRI examination which is magnetic resonance imaging. However, the method is not based on the x - ray but change the magnetic properties from the hydrogen that absorbs the contrast medium. The contrast medium of MRI with the properties is a gadolinium.
