There are three types imaging tests: X-rays, CT scans, and MRI. You may not be familiar with the differences between each type of imaging test. Continue reading to find out more about them and their potential risks. You may be wondering if you should get one for your condition. This article will help you select the right imaging test for your problem. The process of getting a medical picture is simple. Here are some facts about each one.
X-ray
Although X-rays are safe, they do use radiation. Although X-rays can be used safely for adults, they pose a risk to developing babies. It is important that pregnant women, or anyone who plans to become pregnant, inform their doctor before they undergo an Xray. An MRI might be an option. If you are pregnant, it is important to discuss the benefits and risks of X-rays.
Most health insurance policies cover medically necessary X-rays. This procedure may require an additional cost, depending on what type of plan you have. You may have to pay the entire cost of the Xray if your deductible isn't met. To find out exactly how much it will cost, you can call the hospital before you go. A hospital will also be happy to provide an exact quote. Since prices vary from hospital to hospital, this will help you understand what to expect.
CT scan
A CT scan refers to a type medical imaging test. It involves a series of x-rays taken from several angles, which a doctor will then analyze to determine the severity of a patient's condition. The CT scanner has a small motorized examination table that can slide into the center of patients' beds. Inside the machine is a small, pencil-thin tube that emits x-rays from precise angles. The information from each angle can then be fed into the computer to create a black/white image. During a CT scan, special contrast materials are often used to obtain a clearer picture. These substances may be ingested through veins or rectums.
The whole process can take from 20 minutes to one hour. For evaluation, the images are sent to radiologists. The radiologist will examine the images and give their conclusions. A scan without contrast may be preferred by people with allergies. People may receive steroids or medications in some cases to prevent allergic reactions from the contrast. Your doctor should know if you have any one of these conditions so that he can prescribe the best treatment.
MRI
An MRI imaging scan is a noninvasive medical procedure that uses magnet waves to create detailed images. This procedure takes anywhere from 15 to 90 minutes. Women who have hearing aids, metal implants or other metal devices may need to dress appropriately for the procedure. Before undergoing an MRI, pregnant women should discuss the procedure with their doctor. If there are any metal implants in their body, they should inform their healthcare provider so that they can be removed before the scan.
MRI imaging tests can be used to determine the extent of a cancerous tumor or other abnormality. They are excellent for monitoring the progress in cancer treatment as they don't require any surgical procedures. A PET-CT scan requires the use of radiation, and an MRI does not. But it can be dangerous for children. An MRI with contrast may be offered to children who are scheduled for a PET scan. This procedure has many advantages over a CT scan.
Ultrasound
If you're scheduled for an ultrasound, you will be asked to dress in a way that will allow the health professional performing the exam to see the area being imaged. A previous radiology examination may be helpful. Your health professional can discuss the test with you in detail and answer all your questions. Once the examination is over, your health professional will examine the images and talk with you about the results.
The ultrasound uses no radiation and is painless. The ultrasound is used to image internal organs. It can also be used to assist doctors during interventional procedures. You can use some specialized ultrasounds to examine the blood flow through the veins and arteries. You will receive a CD of the results of your ultrasound examination upon completion. This CD should be kept as part of your medical record. If your doctor finds any abnormalities and suggests further treatment, they will recommend a course.
