Weekends and Most Holidays will remain a. Note: Ezra does not use contrast dye. Side effects can include a rash, itching, swelling, or difficulty breathing.
After you get home, keep an eye on your symptoms. Those signs could indicate an infection or delayed reaction.
If you received oral contrast, you may develop diarrhea that should pass once the contrast material has moved through your system. A scan without contrast requires no special care. You can resume your normal activities, including diet. Your doctor will tell you if they want you to change your regular practices after the procedure. Both you and your doctor will receive a copy within a week and be able to access your report online.
CT scanning is a form of medical imaging that is quick and painless. Few people experience claustrophobic reactions to the scanning procedure because of its open design, especially when compared to an MRI scan.
The amount of radiation is more than a standard X-ray, and the amount of radiation depends on the type of scan you will get. If you are at high risk for lung cancer, you can choose to have an elective low-dose CT scan with Ezra. LDCT has been shown to decrease lung cancer-based mortality in recent studies. In just a few easy steps, you can book your LDCT today. Key takeaways: Computed tomography CT scans are non-intrusive and painless. Low-dose CT scans are the ideal preventative measure for patients at risk of lung cancer.
How long does a CT scan take? Do I need a referral for a CT scan? How do I schedule an appointment for a CT? How much does a CT scan cost, and will my insurance cover it?
What should I tell my practitioner before scheduling a CT scan? Do I need an injection of a contrast agent for my CT exam? Should someone accompany me to my screening and drive me home?
Can someone be with me during the exam? Because of radiation exposure, no one else is allowed in the scanning room. How should I prepare for a CT scan? What will happen during my CT scan? Will the CT imaging examination hurt? Doctors often use CT scans to help them guide a needle to remove a small piece of tissue.
This is called a CT-guided biopsy. CT scans can also be used to guide needles into tumors for some types of cancer treatments, such as radiofrequency ablation RFA , which uses heat to destroy a tumor. By comparing CT scans done over time, doctors can see how a tumor is responding to treatment or find out if the cancer has come back after treatment.
In a way, CT scans are like standard x-ray tests. But an x-ray test aims a broad beam of radiation from only one angle. A CT scan uses a pencil-thin beam to create a series of pictures taken from different angles. The information from each angle is fed into a computer, which then creates a black and white picture that shows a slice of a certain area of the body — much like looking at a single slice from a loaf of bread.
Special contrast materials can be used to get a clearer picture. These can be swallowed as a liquid, put into a vein, or put into the intestines through the rectum as an enema. By layering CT image slices on top of each other, the machine can create a 3-dimensional 3-D view. The 3-D image can be rotated on a computer screen to look at different angles. Doctors are now taking CT technology one step further in a technique called virtual endoscopy.
They can look at the inside surfaces of organs such as the lungs virtual bronchoscopy or colon virtual colonoscopy or CT colonography without actually having to put scopes into the body. The 3-D CT images are arranged to create a black and white view on the computer screen. This looks a lot like it would if they were doing an actual endoscopy.
Ask your doctor if you will get contrast dye as part of the CT scan. This is important because reactions to these things may put you at risk for reacting to the contrast dye used in CT scans. People who have had a severe reaction in the past may need to take drugs usually a steroid, like prednisone to help prevent another reaction.
