Skull AP
4
Feb

Overview

The AP skull radiograph evaluates cranial vault symmetry and gross osseous lesions. The patient is positioned upright or supine with the detector centered to the skull. This view is used for initial assessment in trauma and suspected skull pathology.

Technique

Center the detector to include the entire skull and ensure the orbitomeatal line is perpendicular to the detector for standard AP projection. Use appropriate exposure and immobilize the head to reduce motion. Collimate to the skull to minimize dose.

Clinical Indications

AP skull is indicated for trauma suspected fracture and evaluation of lytic or sclerotic lesions. CT is preferred for detailed assessment of skull fractures and intracranial injury. Radiographs may be used when CT is unavailable.

Image Assessment

Inspect cranial vault for fractures lytic lesions and calcifications. Evaluate sutures and skull base when visible. Recommend CT for detailed evaluation of suspected intracranial or complex skull pathology.

Wrist Carpal Tunnel View

Feb

Overview

The carpal tunnel tangential view images the pisiform and volar aspect of the carpal bones to evaluate for pisotriquetral pathology and space occupying lesions. The beam is angled tangentially to the carpal tunnel. This projection is used selectively for specific clinical questions.

Technique

Position the wrist in hyperextension with the beam angled tangentially to the carpal tunnel. Center to the pisiform and use a small focal spot for detail. Immobilize the wrist to reduce motion and ensure reproducibility.

Clinical Indications

Carpal tunnel view is indicated for suspected pisiform fractures ganglia or space occupying lesions causing median nerve compression. It complements standard wrist series and ultrasound or MRI for soft tissue evaluation. Use selectively due to patient discomfort in hyperextension.

Image Assessment

Assess pisiform integrity volar carpal contour and presence of calcified or radiopaque lesions. Correlate with clinical signs of median nerve compression. Recommend further imaging such as MRI for soft tissue characterization.
