An AP (anteroposterior) foot X‑ray is a frontal radiograph taken with the foot flat on the detector and the X‑ray beam directed from front to back. It visualizes bones, joints, alignment, fractures, dislocations and degenerative changes. AP images are often combined with lateral and oblique views to fully assess injuries, foreign bodies, infection or arthritis, and to guide treatment planning.

AP view in X‑ray means anteroposterior projection: the X‑ray beam travels from the front (anterior) to the back (posterior) of the patient onto the detector. It's commonly used for supine or portable exams when the patient can't stand. AP views can magnify anterior structures (e.g., heart) compared with PA views, so interpretation considers position and detector distance.

The best approach is a standard three-view foot X-ray: weight-bearing dorsoplantar (AP), lateral, and a 30° oblique. Weight-bearing images are preferred when assessing alignment, joint spaces, and subtle instabilities or arthritis. Non–weight-bearing views may be used for acute trauma if the patient cannot stand. Additional targeted projections or CT may follow for complex fractures.

Costs vary by country and facility. Typical charges for a foot X‑ray (AP and oblique) range: India ₹200–₹1,000; United Kingdom private clinics £30–£120 (NHS usually free for eligible patients); United States $50–$300 (hospital rates can be higher). Final price depends on location, facility type, and whether radiologist reporting or urgent service is included—confirm with your provider.

AP stands for anteroposterior. In an AP X‑ray the X‑ray beam travels from the front (anterior) to the back (posterior) of the body. It’s commonly used for portable or supine chest radiographs when a patient can’t stand. AP views can magnify anterior structures (for example, the heart) and differ in appearance and projection from PA views.

For an AP (AP axial) foot radiograph, angle the central ray about 10 degrees toward the heel (posteriorly/caudad along the foot’s long axis). This small angulation opens tarsometatarsal and metatarsophalangeal joint spaces and reduces foreshortening of the metatarsals. A true non‑axial AP uses a perpendicular central ray.
