For skull radiographic examinations, which projection is generally preferred?

For skull radiographic examinations, the posteroanterior (PA) projection is generally preferred because it effectively demonstrates the frontal sinuses and the orbits while minimizing the dose of radiation to sensitive tissues, such as the lens of the eyes. In a PA projection, the beam enters from the back of the skull and exits at the front, allowing for better visualization of anatomical structures in their natural positions.

Additionally, the PA projection helps to reduce magnification of the structures that are close to the image receptor, providing a more accurate representation of size and spacing, which is crucial for diagnostic interpretation. This projection also minimizes distortion and allows for clearer imaging of the facial bones and nasal septum, enhancing the overall quality of the radiographic examination.

In contrast, other projections might not provide the same level of detail or may expose more sensitive areas to radiation, thereby making the PA projection the optimal choice for evaluating skull anatomy.
