What is the concept of "dose creep" in digital radiography?

Dose creep refers to the phenomenon observed in digital radiography where there is a tendency for technologists to increase exposure factors, such as radiation dose, without a corresponding improvement in image quality. This often occurs because digital imaging systems can handle a wider range of exposure levels compared to traditional film-based systems. As a result, radiographers might feel more comfortable operating at higher exposures, thinking that it will produce better-quality images. However, this can lead to patients receiving unnecessary additional radiation, raising safety concerns and reducing adherence to the ALARA (As Low As Reasonably Achievable) principle in radiological practice.

Understanding dose creep is crucial in maintaining a balance between achieving diagnostic quality images and minimizing patient exposure to radiation. It emphasizes the importance of consistent application of exposure protocols and the need for ongoing education and awareness around optimal imaging practices.
