MRI is also known as the magnetic resonance imaging test. It is a kind of non invasive test which mainly uses magnet and some radio waves so that they can create some necessary images of a human body. These radio waves and magnets crate some cross sectional images of the abdomen and by looking at those sketches the doctor can find out if there are any abnormalities in the organs and tissues of a human body.
One can check the cost of MRI abdomen in Bangalore from the hospitals and the radiology centres where this test is performed. The technology that is mainly used to do an MRI mainly allows the doctor to examine the soft tissues and the bones that are creating problems in the human body. One goes for an MRI because there are no radiations used in the test and it is considered to be a safe option than a CT scan.
Now the question is why a doctor prescribes for an MRI in the abdomen area? Well, this is mainly prescribed if the doctor finds that there are abnormal results from some earlier tests like CT scan, X ray or any other blood tests.
Abdominal MRI is mainly performed in order to find out various reasons. The doctors mainly prescribe an MRI if they think that there is something wrong in the abdominal area of the patient but that is not found in other physical examination. The doctor can ask the patient to do an MRI because they need to find out:
- The blood flow rate.
- To check the blood vessels.
- In order to investigate the cause of any kind of swelling or pain.
- In order to examine the lymph nodes
What are the risks involved in an MRI?
There are actually no major side effects that can happen from an MRI. But yes, when an MRI test is done no metal objects are allowed near the scan machine because the machine that is used for the test has magnets. So, if one has any kind of metal implants in their body or some detained metal fragments like a shrapnel or a gunshot wound then they should definitely let the doctor know about it. if someone is claustrophobic then they should definitely tell the doctor about their problem. One can also feel uncomfortable when they are near the machine. For this, the doctor can prescribe a medication to reduce the anxiety and this sedative can help the patient to relax.
Before undergoing an MRI the doctor needs to check if the patient has any:
- artificial heart valves
- clips, pins, or screws
also, before the test the patient should inform the doctor if they have any pace maker. Now depending on the type of pace maker the doctor can also suggest a different kind of radiology program for the patient like the abdominal CT scan. There are also some pace makers which can be re programmed and so they do not create any disruption during the time of MRI.
Sometimes the doctor may need the images of the colon of a patient and for that the patient may require some laxative or some kind of enemas before the MRI takes place. One also needs to fast for at least 4 to 6 hours before the test is done. In fact, the doctor might also use some special dye during the test if they think they need to highlight certain areas in a human body. This particular dye is known as the gadolinium and it can be administered easily through an IV. Though allergic reactions rarely happen due to this IV one can still inform the doctor if they are prone to allergies.
How is an MRI performed?
In most cases the MRI is performed in a machine which looks like a hollow cylinder. It also has a bench which very slowly glides the patient into that large cylinder like tube which is attached to it.
The technician will ask the patient to lie on their back on the bench and will give them a thin blanket or a pillow. The technician will also control the movement of the bench by using a remote control from an adjacent room and they will also communicate with the patient over a microphone.
Once the test starts, the machine will start making loud whirring and clinging noises as it begins to take the images. Many hospitals also ask the patient to wear earplugs or headphones so that the noise does not disrupt their peace and the test can be done easily. MRI machines are also very sensitive to movements. So it is important that the patient should stay very still. The technician may also ask the patient to hold their breath for a few seconds as pictures are taken properly.
One will not feel anything during the test. The magnets and radio frequencies are very low and so it does not affect the patient. Also the entire test takes only 30 to 60 minutes depending on the organs that are tested.
When the MRI is done, then the patient is actually free to go home. There is no need to stay back at the hospital. When the scan images are projected into a film, it can actually take hours to get the film developed. It will take some more time for the doctor to study and review the images. The modern machines display images on a computer so that the doctor can view them instantly. Also once the result is viewed then the doctor can decide on the course of medication. They can also decide if the patient needs any kind of surgery or not. They can also see if their given medication is working on the patient or not.
One can ask for the cost of mri abdomen Bangalore and then take an appointment at the hospital for the test. Once the test is done the patients are asked to drink a lot of water to flush out the dye.
