AP (anteroposterior) view: X‑ray beam passes from the front (anterior) to the back (posterior) of the body; detector sits posteriorly. Often used for chest or trauma when patients can’t stand; may alter apparent heart size. Lateral view: beam passes from one side to the other, producing a side image that shows depth and separates overlapping structures — useful for locating lesions, fractures, or effusions.

Position the patient seated with the affected arm on the table. Abduct the thumb and rest it laterally on the image receptor so the thumb’s palmar surface is perpendicular to the detector. Include distal phalanx, interphalangeal and metacarpophalangeal joints. Use a sponge or tape to immobilize, center the beam at the MCP joint, set appropriate exposure, and add a radiopaque marker and shielding.

The lateral hand X‑ray is a side projection obtained with the hand placed laterally on the detector (ulnar side down), fingers extended and superimposed so the bones form a true lateral profile. It displays phalanges, metacarpals and carpal alignment in the sagittal plane, allowing assessment of fractures, dislocations, angulation, dorsal/volar displacement, and detection of foreign bodies or joint-space abnormalities.

Place the patient so the anterior surface faces the X‑ray source and the image receptor is behind the posterior surface. Center the central ray perpendicular to the receptor at the area of interest, collimate to the field, set appropriate exposure, and use shielding. Ensure no rotation, include side marker and patient ID, and instruct the patient to hold breath (for chest) and remain still during exposure.

AP (anteroposterior) and lateral are two radiographic views — together they make a two‑view examination. The AP view images structures front‑to‑back (often used portably or supine), while the lateral gives a side‑to‑side perspective. Using both views improves localization, uncovers overlapping pathology missed on a single projection, and aids assessment of lung, mediastinal, and bony structures.

Lateral in an X‑ray means a side‑view image taken with the X‑ray beam passing from one side of the body to the other. It provides depth information, separates overlapping structures seen on front/rear views, and helps localize lesions, assess alignment, or visualize posterior anatomy. Lateral films are labeled right or left to indicate which side of the patient is against the detector.
