RBC Liver Scan for Hemangioma
Why would my physician order this procedure
To help differentiate between hemangiomas (benign tumor made up of new-formed blood vessels) or other masses within the liver.
There is no special preparation.
To perform this exam, we must give you a small amount of radioactive materials.
Tell your doctor if you might be pregnant, if you are pregnant, or if you are a nursing mother.
What to expect
A technologist will explain the entire process to you prior to starting the exam. He/she will also ask you some health history questions, which will help our radiologist interpret your exam.
A technologist will place an intravenous (IV) line in your arm. He/she will draw some blood (about 5 cc) through the IV line. You will be free to go anywhere for about 30 minutes while your blood is being labeled with a radiopharmaceutical reagent.
When you return, you will be asked to lie on our scanning bed with both of your arms placed over your head. A technologist will use the inserted IV line to reinject you with your labeled blood.
To acquire the study, the imaging cameras will be positioned close to your chest/abdomen area while they rotate 360 degrees around you. You will be asked to remain as still as possible during the scan, as any motion effects the quality of the study.
Upon completion of the immediate scan you will be given a time to return for the delayed images. The delayed images will be acquired exactly the same as the immediate set.
If you have any technical questions specific to this procedure, please don’t hesitate to ask the technologist at scan time. All clinical questions should be directed to your physician.
A report will be sent to your ordering physician.
How long will it take
Total time for this exam runs about 4 hours.
Possible complications or side effects
No complications are expected from this procedure.
Radiation risk statement
Studies of the health effects of radiation have shown that high doses of radiation can cause cancer. However, this hospital procedure requires that we inject you with a very low level of radioactive material.
The risk from lower doses of radiation, such as you will receive during this exam, is uncertain. Most scientists believe that the risk is very small. Certainly, the benefits received from the exam far outweigh the small risk associated with this procedure.
