What is the typical mA used for spot films?

In fluoroscopy, spot films are used to capture images at specific moments during a procedure, and the process requires a sufficient amount of radiation to produce high-quality images. The typical mA (milliamperage) settings for this purpose usually range around 100 mA.

Using 100 mA for spot films ensures that the images have enough exposure to produce clear, detailed views of the anatomy or pathology being examined. This level of mA strikes a balance between producing good image quality and maintaining patient safety, minimizing unnecessary radiation exposure while still providing diagnostic-quality images. In practice, the selected mA for spot films depends on the procedure being performed, but 100 mA is commonly utilized for its effectiveness in achieving optimal results. Higher mA settings can yield better image quality but may also increase radiation dose, thus, 100 mA is often seen as the standard for achieving a good compromise.
