On your arrival, the doctor will ask you to wear a gown. Due to the use of magnets, it’s important that you are not wearing any metal objects. So the doctor will ask you to remove any metal jewelry or accessories that may interfere with the machine. Also, the person cannot undertake an MRI if they have metal inside their bodies such as shrapnel, bullets or other metallic foreign bodies. The list includes cochlear implants, pacemakers, implants, and aneurysm clips.
As radiation is not used in an MRI, there are no risks involved. But due to the use of a strong magnet, an MRI scan is not recommended for patients with implanted pacemakers or other types of iron-based metal implants.
No, the only few reactions that are common are minimal such as headache, nausea, and dizziness for a brief period. Some people may feel coldness at the injection site.
Yes, CT scans use X-Rays to form images inside the body, but MRI uses powerful magnetic fields and radiofrequency pulses to give detailed images of organs. CT scans use harmful radiation that MRI’s do not.
It’s a machine that looks like a long narrow tube with both ends open. The MRI machine makes a strong magnetic field around you, in which radio waves are directed at you. This procedure is painless, as you don’t feel the magnetic field. Also, there are no moving parts around you.
CT Scans utilize a narrow beam that circles one part of your body. This test gives a series of images from different angles, which a computer uses to create cross-sectional pictures. For example, a single slice in a loaf of bread.
This process is repeated to produce several slices. These scans are stacked over each other by a computer to produce a detailed image of your bones, blood vessels, or organs. Example, a surgeon uses these scans to study a tumor before preparing an operation.
Your doctor might ask you not to eat or drink for a couple of hours before the procedure. Also, you may need to wear a hospital gown or remove any metal projects such as jewelry. You might hear a whirring or buzzing sound during a CT. Movement can blur the images, so you’ll be asked to stay still.
The time taken depends on the body parts that are being scanned. It can take anywhere from a few minutes to a half-hour, so you can go home the same day.
Yes, unlike MRI, a CT doesn’t have any risks associated with metal objects.
CT Scan is a low-risk test. Most of its safety issues are associated with a small amount of radiation. This risk is greater among younger people, as a result, CT scans are generally avoided in those under age 20-30. It is used with caution in those who are between 30 to 50 age group. However, on any given day, the immediate benefits of a CT scan outweigh the long-term cancer risk.
There is no special preparation needed for most X-Ray exams. You are asked to wear a hospital gown and remove jewelry and metal objects before you take it.
You are asked to lie on a table or stand next to the X-Ray machine. The technologist performing the scan may use cushions to help you hold the proper position. You may be asked to keep yourself very still, without breathing for a few seconds. In case, multiple images or views are required, you’ll be asked to reposition for another view.
X-ray scans are fast and easy and usually take only 5 to 60 minutes.
X-Rays expose you to radiation. The small amount of radiation depends on the X-ray scan you want. For example, the brain, lungs, abdomen and the X-ray machine type. The exposure to radiation is variable and its risks are also variable. Women who are pregnant should inform their doctor if they are or may be pregnant. You will not feel the radiation.
You will not feel the radiation. Just minimal clicking or buzzing noises are heard while it is being performed.
If there is no emergency, it mostly takes a day or so to interpret, report, and deliver the report.
Plaque is partially made of calcium and fat. Initially, it’s waxy, and it builds up slowly, but overtime it hardens and is called calcified plaque.
Like a clog in the pipe, hard plaque blocks your arteries by slowing down your blood flow. This means that many parts of your body don’t get their fill of oxygen. If plaque is accumulated in your arteries, you can experience chest pain and discomfort, known as angina. Secondly, if plaque breaks open it can lead to a blood clot. This can lead to a heart attack.
Your calcium scoring shows how much-calcified plaque exists in your heart’s arteries. Henceforth, your doctor can decide if your medication or lifestyle need changes.
Get this calcium test done if you feel you are likely to get heart disease. Your doctor can figure this out with the help of details such as your age, blood pressure, cholesterol level, whether you smoke, and your gender.
For calcium scan, you need to visit a clinic that consists of a CT scanner. First and foremost, the doctor will ask you to avoid caffeine and smoking for up to 4 hours before the test. For the scan, you have to put on a hospital gown, remove your clothes and jewelry from the upper body part.
A few sticky patches will be put on your chest by the person running the scanner. These patches will be connected to an EKG machine that helps the person know when to take the images of your heart. If you are claustrophobic, you will be given the med to slow your heart so better pictures can be taken.
During the calcium heart scan, you have to lie on your back on a table, which slowly moves into the CT scanner. This scanner is a hollow tube that slides into a tunnel and, your head stays out of the tube at all times. When you are done, you are free to go about your day.
