AP view is taken form the front and PA is taken from the back.
Anterior posterior view
the ventral cavity is anterior to the dorsal cavity which is in the posterior.
It's the same bone viewed from the back. Anterior is the front view of the right femur and posterior is the back view of the right femur.
Anterior view refers to the front view of the body or an anatomical structure, showing the surface that is facing forward. It is the opposite of posterior view, which shows the back or rear side of the body or structure.
In radiology, "PA view" stands for "Posteroanterior view." It refers to a specific imaging technique where X-rays are taken with the X-ray beam directed from the back (posterior) to the front (anterior) of the body. This view is commonly used in chest radiography to assess lung conditions, heart size, and other thoracic structures. It helps provide a clear visualization of the anatomy by minimizing distortion.
The radiographic projection taken back to front is called a "posteroanterior" (PA) projection. In this technique, X-rays pass from the posterior (back) side of the body to the anterior (front) side. This projection is commonly used in chest radiography to visualize the heart and lungs while minimizing distortion and providing a clear view of these structures.
A PA lateral view, or posteroanterior lateral view, is a type of radiographic imaging used primarily in chest X-rays. In this view, the X-ray beam passes from the back (posterior) to the front (anterior) of the body while the patient is positioned sideways. This orientation helps in visualizing the structures of the chest, including the lungs, heart, and surrounding tissues, providing crucial information for diagnosing various medical conditions. It is often used in conjunction with other views for a comprehensive assessment.
A posteroanterior (PA) chest X-ray is taken with the patient standing or sitting upright, facing the X-ray film. The X-ray beam is directed from the back (posterior) of the patient to the front (anterior), ensuring that the heart and other structures are captured in a clear frontal view. The patient is typically instructed to take a deep breath and hold it to enhance the visibility of the lungs and heart on the image. Proper positioning helps reduce distortion and provides an accurate representation of the thoracic cavity.
To see the apecies of the lung. In a regular PA view of the chest the clavicles and ribs are in the way, sometimes shadowing stuff. So an apical view or lordotic view is taken so they are not superimposed.
