posteroanterior , PA (Abkürzung)

All children entered into the study had a posteroanterior chest radiograph after the above data were recorded.

The most common views are posteroanterior, anteroposterior, and lateral.

Influence of load orientation on the posteroanterior stiffness of the lumbar spine.

The second group consists of finely divided fragments, distributed in a posteroanterior direction in a region 45 mm.

The left atrial appendage can be seen on a standard posteroanterior x-ray, where the lower level of the left hilum becomes concave.

There needs to be at least 75ml of pleural fluid in order to blunt the costophrenic angle on the lateral chest radiograph, and 200ml on the posteroanterior chest radiograph.

Treatment is encouraged as early as possible with posteroanterior traction on the maxilla and, at about age 8, reinsertion of the nasolabial muscles onto the anterior border of the cartilaginous system.

The greatest advantage to DEXA is its versatility, as virtually any skeletal site can be measured, including the spine (in both posteroanterior and lateral projections), proximal femur, forearm, hand, and total body.

Chest xrays (CXR): baseline CXR was performed in the posteroanterior position and postoperative CXR in the anteroposterior position in the intensive care unit.

Lateral views of the chest are obtained in a similar fashion as the posteroanterior views, except in the lateral view, the patient stands with both arms raised and the left side of the chest pressed against a flat surface.

Males seem to have small scales in the anal region that are more strongly keeled than scales elsewhere on the body (the scales catch on finger tips when rubbed in a posteroanterior direction), but males lack small tubercles on the upper and lateral parts of the head as mentioned by Maslin (1950:433).
