Final answer:
A radiologic procedure indeed requires a completed radiology order before it can be performed. This ensures the test is done correctly and allows for proper preparation, including the administration of radiopharmaceuticals if needed.
Step-by-step explanation:
Before a radiologic procedure is performed, a radiology order must be completed. The answer to this is true. A radiology order is a document that includes the physician's instructions regarding the imaging test required, including the type of procedure, the area of the body to be examined, and the reason for the imaging. This ensures that the correct test is performed and that any necessary preparations are made, such as the administration of radiopharmaceuticals. These substances are often used in diagnostic tests such as PET scans and have various properties, like half-lives and the time they take to pass through the body, which can affect how and when the imaging is done. For example, PET scans sometimes need to be performed soon after ingesting a radiopharmaceutical due to the short half-life of the substance and to capture the metabolically active tissues of the organ or organs being targeted.
