Photon-counting computed tomography (PCCT) represents a significant advancement in head and neck imaging, offering both technical and clinical benefits over conventional energy-integrating CT (EID-CT). This revolution is mainly based on the five technical aspects: improved spatial resolution, reduced image noise and metal artifacts, lower radiation exposure, decreased iodinated contrast dose, and spectral imaging...

No actionable change for audiologists at this time — PCCT is an emerging radiology technology whose clinical advantages are documented in a review, but adoption depends on radiologist and hospital decisions, not audiology practice.
PCCT's superior resolution and material-differentiation capabilities could improve detection of subtle temporal bone and head-and-neck pathology, potentially enhancing diagnostic referral pathways relevant to audiologists.
- 01PCCT detects individual X-ray photons, yielding higher spatial resolution than conventional energy-integrating CT.
- 02The technology offers improved soft-tissue contrast and reduced radiation dose for head and neck imaging.
- 03Review covers both the detector physics and clinical applications relevant to head and neck radiology.
- 04Potential audiology-adjacent benefits include better imaging of the temporal bone, ossicles, and related structures.
- 05Widespread clinical adoption remains limited by scanner cost and availability.
PCCT provides technical and clinical advantages over conventional energy-integrating CT for head and neck imaging.
