A renal scan, also known as a kidney scan, is a vital diagnostic tool used to assess the function and structure of your kidneys. This procedure utilizes a radioactive tracer and a special camera to create detailed images of your kidneys, helping your doctor identify any potential issues. If you’re scheduled for a Renal Car Scan Of Kidney, understanding what to expect can ease any anxiety and prepare you for the process.
What Happens During a Renal Scan?
The renal scan procedure is generally straightforward and painless. Initially, a small amount of radioactive tracer is injected into your bloodstream, usually through an intravenous (IV) line in your arm. This tracer is designed to collect in your kidneys, allowing them to be clearly visible during the scan. You may need to wait for a period of time to allow the tracer to properly accumulate in your kidneys before the imaging begins.
When it’s time for the scan itself, you will be positioned on a scanning table. This might involve lying down or sitting, depending on the specific equipment and the images required. A special camera will then be used to detect the radioactive tracer in your kidneys and create images. The camera may move around you to capture images from various angles, or you might be asked to change positions to facilitate comprehensive imaging.
During the scan, a technician will monitor the image quality to ensure they are clear and diagnostic. It’s not uncommon for the technician to request repeat images from certain positions to obtain better views or additional perspectives. If this happens, it doesn’t necessarily indicate a problem with your kidneys; it’s simply a standard procedure to ensure the highest quality images are obtained for accurate diagnosis.
The duration of a renal scan can vary depending on the specifics of the test being performed. Generally, you can expect the scan to take anywhere from approximately 30 minutes to as long as 2 hours.
Once the scanning is complete, the IV line will be removed, and you will typically be free to go home shortly after. The medical team may advise you to drink plenty of fluids for the next 24 hours. This is important as it helps to flush the radioactive tracer out of your system through frequent urination.
It’s important to monitor the IV insertion site after the procedure. If you experience any redness, pain, or swelling at the site, it’s essential to inform your doctor. These symptoms could indicate a possible infection or a reaction to the tracer.
Understanding the Risks Associated with a Kidney Scan
Renal scans are considered to be safe procedures with minimal risks. The amount of radioactive material used in the tracer is very small, which significantly reduces the risk of any adverse effects from radiation exposure.
While rare, allergic reactions to the tracer are possible in a few individuals. It’s important to inform your medical team of any known allergies before the procedure.
For some individuals, the most significant discomfort during the scan is the need to remain still for an extended period. If you anticipate difficulty staying still due to pain or other conditions, discuss this with your doctor beforehand.
It is crucial to inform your doctor if any of the following conditions apply to you prior to undergoing a renal scan:
- Pregnancy or potential pregnancy: Renal scans may not be safe for pregnant women as radiation exposure could pose risks to the developing fetus.
- Breastfeeding: The radioactive tracer could potentially contaminate breast milk. Special precautions may be necessary if you are breastfeeding.
- Allergies or sensitivities: Inform your doctor if you have any allergies to medications or if you are sensitive to latex.
- Claustrophobia: If you suffer from claustrophobia, let your doctor know, as the scanning camera may move close to your body during the procedure.
Decoding Your Renal Scan Results
After your renal scan is completed, the images will be carefully reviewed by a radiologist or another physician who is specially trained in interpreting medical images. The radiologist will then prepare a detailed report based on their findings. This report will be sent to the doctor who ordered the renal scan for you. Your doctor will then discuss the results with you, explaining what the scan revealed and outlining any necessary next steps or treatment plans.
