What should be assessed in a patient’s history before performing radiological procedures?

Assessing a patient's previous drug use and potential allergies is crucial before performing radiological procedures. This assessment is essential because certain contrast media and radiopharmaceuticals used in imaging can provoke allergic reactions in sensitive individuals. For instance, contrast agents containing iodine may trigger an allergic response in patients with a history of allergies, particularly to shellfish or prior contrast agents. Understanding a patient's drug history helps in anticipating any adverse reactions and ensuring patient safety during imaging procedures.

In addition, knowing about the patient's previous medications can provide insights into possible interactions with contrast agents or medications that may affect their renal function, which is particularly important when using iodinated contrast. This history aids in making informed clinical decisions, reducing the risk of complications associated with radiological imaging.

Other assessments, such as family medical history, economic status, and previous procedures, are important but may not be as directly relevant to immediate patient safety related to the administration of radiological substances as understanding previous drug use and allergies.
