An MRI scan is a safe and painless imaging modality. The images provided from the MRI scan are the basis for the doctor to develop an effective treatment plan. Let’s learn about MRI scan with Bach Hoa Xanh!
What is Magnetic Resonance Imaging?
Magnetic Resonance Imaging is a method that uses strong magnetic fields, radio waves and computers to sketch detailed images of the inside of the human body . From there, the doctor can diagnose the patient’s health condition.
Magnetic resonance imaging (MRI) is of high quality, sharp, clear, detailed. Magnetic resonance imaging (MRI) is indicated for the skull, eye sockets, neck, spine, abdomen – pelvis, musculoskeletal, mammary glands, congenital malformations or heart and vascular diseases…
Benefits of Magnetic Resonance Imaging (MRI)
- Unaffected by radiation.
- Biologically unaffected.
- Multi-plane image, easy to diagnose.
- High resolution , good image display.
- Contrast has almost no side effects.
- Effective and modern paraclinical techniques.
- Fast shooting time , maximum noise reduction.
- Angiography does not require contrast injection.
Which parts are indicated for MRI?
- Cranial imaging is used to check and detect brain tumors, cranial nerve tumors, cerebrovascular accidents, brain bleeding, degenerative white matter disease, meningitis, birth defects of the brain, etc. .
- Orbital imaging to detect lesions of the eyeball, optic nerve,…
- Neck scan to detect tumors, inflammation, lymph nodes, brachial plexus, …
- Spinal imaging to detect spinal diseases, discs, ligaments, spinal diseases such as inflammation, tumors, …
- Abdominal – pelvic imaging to detect liver, biliary tract, pancreas, spleen, kidney, colorectal, prostate cancer, uterine tumours,…
- Musculoskeletal imaging to detect diseases such as inflammation, degeneration, ligament tear injury, joint effusion, etc.
- Mammography is used to diagnose breast lesions such as tumors and infections early.
- Diagnosis of fetal abnormalities, complex birth defects. MRI is also used to diagnose heart and blood vessel diseases.
Advantages and disadvantages of magnetic resonance imaging (MRI)
- The method allows the doctor to observe the internal characteristics of the body with the criterion of no harm or danger to the human body.
- The patient does not need to move during the scan.
- With state-of-the-art technology, more than 250 shades of gray to distinguish different parts of tissue, MRI produces very high-quality, clear, easy-to-read images.
- Ask the patient to remain completely immobile during the scan.
- Not suitable for emergency use.
- Very loud noise during shooting.
- The cost of shooting is quite high.
Magnetic resonance imaging (MRI) procedure
MRI scan time can last from 20 to 90 minutes, including 3 procedures:
Tell your doctor if you have certain chronic medical conditions or have recently had surgery, are allergic to food or medicine, are pregnant or may become pregnant. Before taking the scan, you can eat and drink normally, except for foods and drinks that are on the doctor’s list of prohibited items. Next, change your clothes and follow your doctor’s instructions.
Inject a contrast agent into a vein. Next, you’ll lie inside the MRI machine (full or partial) and use straps to immobilize you during the test.
Be able to go home and resume normal activities. The specialist will analyze the images and pass the results to the doctor who is treating you. From there, the doctor will determine the condition of the disease.
Some related questions
Does magnetic resonance imaging affect health?
The MRI scanner does not produce any harmful side effects for the patient. However, there is a risk if you carry some metal objects inside your body.
How long does it take to get results from an MRI scan?
The time to take an MRI and return the results takes place from 20 to 60 minutes or maybe longer.
Can pregnant women have an MRI?
Pregnant women can have an MRI, but during the first trimester of pregnancy, pregnant women are often advised not to have an MRI unless absolutely necessary.
Is the MRI with contrast injection?
You may be given a contrast injection before or during the MRI scan. Because this drug works to improve the clarity of images inside the body.
Can MRI scans detect cancer?
MRI is one of the most effective cancer screening methods.
Does magnetic resonance imaging require fasting?
Are not. You should eat well, keep your mind stable to ensure enough health for the MRI scan.
Does an MRI reduce life expectancy?
Does not affect human lifespan.
How is magnetic resonance imaging different from CT scans?
- An MRI uses radio waves and a CT scan uses X-rays.
- CT scans can harm an unborn baby, there is a very small dose of radiation that has the potential to develop into malignancies.
- Risks of MRI: affect hearing, increase body temperature, cause claustrophobia syndrome.
- CT scans are faster but MRI images are more detailed than CT scans.
