The patient's history of allergies is a crucial factor in determining the use of contrast media in radiographic procedures because allergic reactions can range from mild to severe. Patients with a known history of allergies, especially to iodinated contrast agents or other components of contrast media, require careful assessment to minimize the risk of adverse reactions. This necessitates pre-procedure evaluations, including obtaining a thorough medical history, to ensure patient safety.

While the length of the procedure, cost of the procedure, and type of imaging equipment may impact planning and operational considerations, they do not directly address the safety and well-being of the patient in the same critical manner as allergy history does. Therefore, ensuring that a patient does not have a problematic allergy is paramount to selecting the appropriate contrast media for radiographic procedures.
