AP (anteroposterior) view: frontal X‑ray beam passes from front to back; often used when patients cannot stand (supine or portable chest), shows overall anatomy and mediastinal contours but can magnify structures. Lateral view: side‑to‑side projection at right angles to AP, separates overlapping structures, shows depth, anterior–posterior alignment, spinal curvatures, and air‑fluid levels. Together they localize fractures, masses and alignment.

Clavicle AP refers to an anteroposterior X‑ray projection of the collarbone. It images the clavicle front-to-back to detect fractures, malalignment, nonunion or displacement. Typically done upright or supine with the beam centered over the clavicle; angled cephalad views can be added to profile medial or lateral ends. It’s a standard initial study for suspected clavicular injury.

A clavicle X‑ray cost varies by country and setting. In publicly funded systems (e.g., NHS) it’s usually free at point of care; in India private clinics it’s commonly around ₹200–₹1,000. In the US out‑of‑pocket prices typically run about $100–$500, higher in emergency departments or when radiologist/consultation fees apply. Price depends on facility, number of views and reporting.

Remove clothing and jewelry over the shoulder and apply lead shielding. Position the patient upright (or supine if trauma) with arms at the sides and the affected shoulder against the image receptor. Center the central ray at the mid‑shaft of the clavicle. Obtain an AP view plus an angled view with a 15–30° cephalic tilt to project the clavicle above the ribs. Instruct the patient to suspend respiration during exposure.

AP view on an X‑ray means an anteroposterior projection: the X‑ray beam travels from the front (anterior) to the back (posterior) with the image receptor behind the patient. It’s commonly used when patients can’t stand. AP films can magnify the heart and alter mediastinal contours compared with standard PA views, so interpretation requires caution, noting positioning and inspiratory effort.

Lateral in an X‑ray refers to a side view obtained with the X‑ray beam passing from one side of the body to the other. It is perpendicular to frontal (AP/PA) views and reveals depth, separates overlapping structures, and improves visualization of anatomy. Lateral films are commonly used for chest, spine, skull, and joint imaging to localize lesions and assess alignment.
