An AP (anteroposterior) view of the finger is an X‑ray projection with the palmar surface placed on the detector and the X‑ray beam directed from anterior to posterior. It visualizes phalanges, interphalangeal joints and joint spaces, and detects fractures, dislocations, osteoarthritis and alignment. Proper technique uses the finger fully extended, centered at the PIP joint with beam perpendicular and including distal phalanx to metacarpal head.

A standard finger X‑ray typically includes three views: posteroanterior (PA), oblique and lateral. PA shows joint spaces and alignment; oblique highlights fractures and cortical detail; lateral assesses displacement and rotational deformity. For the thumb, an AP or dedicated lateral plus oblique is often used. Additional specialized views are taken if specific injury or a foreign body is suspected.

A routine finger X-ray typically includes three views: anteroposterior (AP), lateral, and oblique. These three projections help detect fractures, joint dislocations, and alignment problems. In some cases two views (AP and lateral) may be used initially, while additional specialized views are obtained if more detail is required. Your clinician decides which views are needed based on symptoms and exam.

AP (anteroposterior) and PA (posteroanterior) are chest X-ray projections. In AP the X-ray beam passes from the front to the back; it is often used for supine or portable films and can magnify the heart. In PA the beam passes from back to front with the patient facing the detector; this upright view reduces cardiac magnification and better shows lungs and mediastinum.

AP (anteroposterior) view is identified by a label or note, patient orientation (beam enters the front and detector is posterior), and characteristic features: clavicles look more horizontal, scapulae project over lung fields, and the heart silhouette may appear magnified. Bedside or supine films are commonly AP. Confirm by checking positioning markers and the radiology/clinical notes.

The hand AP (anteroposterior) position is obtained with the patient seated, elbow flexed 90°, and the forearm and hand resting flat on the image receptor with the palm facing down. Fingers are extended and slightly separated, wrist neutral, and the hand centered. The central x‑ray beam is perpendicular to the third metacarpophalangeal joint to include the distal forearm and avoid rotation.
