You should know the purpose of your doctor's scan before you go ahead and have one. Your doctor can recommend the right diagnostic test for your condition based on symptoms, risk factors and health history.
Difference between MRI Scans and CT Scans
CT scans, also known as X ray imaging procedures, are used to produce detailed images of the human body. It is often faster and cheaper than an MRI. It's also less invasive, so it is suitable for those who are larger or have claustrophobia.
It can be sensitive when there are diseases or injuries in the area. It can be used to detect cancer tumors, organ damage and vascular abnormalities like stroke.
Ultrasounds, on the contrary, use high-frequency soundwaves to create an impression of your body. It is used for a variety of purposes, such as examining internal organs or muscles.
Contrary to MRIs, ultrasounds can be performed safely on pregnant women as long they do not have allergies or other conditions that might affect the results. An ultrasound can be enhanced by adding a contrast agent to enhance images generated by the machine.
A ct-scan is similar to an image taken with X rays. However, it offers a better resolution and allows the scan to be focused on the exact area. It is much faster than MRIs and can be utilized to quickly diagnose certain diseases.
It can be done with less ionizing radiation than an MRI and is easier on the kidneys. It can also be a good option for patients allergic to liquid contrast agents used in most CT scanners.
The ultrasound may be a better choice for some people, as it is cheaper and has less risk of harming the patient. It is less invasive and doesn't expose patients to ionizing radioactivity, so it's safer for children and pregnant women.
Your doctor is unlikely to order a CT scan when you are pregnant because the radiation exposure can harm the baby. Having an ultrasound instead of a CT can help prevent these risks for pregnant patients.
It is not recommended that pregnant women have an MRI done with a contrast agent, as it can harm their baby. Also, it is not recommended for those who are taking drugs or have a weak immune systems. They may be at greater risk of becoming ill.
Patients who have suffered a heartattack or another traumatic event, and are looking for a clear image of their internal anatomy in order to determine if surgery is needed, may benefit from a CT scan. It can be useful in determining whether a brain injury is severe, or for imaging the abdomen and diagnosing conditions such as appendicitis. Patients who have had a stroke can also benefit from this test as it helps to determine the cause of their stroke, allowing them to begin the right treatment.
