How are lateral projections typically marked?

Lateral projections in radiology are typically marked according to the side of the patient closest to the film. This practice helps to provide clear identification of which side of the patient's anatomy is being represented in the image. Marking in this way ensures that healthcare professionals can correctly interpret the images, reducing the likelihood of confusion or misdiagnosis.

By placing the marker on the side nearest to the film, it is easier for anyone reviewing the images to understand the orientation of the x-ray and the specific anatomical structures being visualized. This approach is consistent across various imaging modalities and helps maintain clarity in patient records and communication among healthcare providers.
