Summary

This pilot study evaluates the clinical utility of photon counting detector computed tomography (PCD-CT) in PET-CT imaging for head and neck cancer. Twenty adult patients undergoing standard-of-care PET-CT will also receive PCD-CT imaging. The study compares image quality and diagnostic confidence between conventional energy-integrating detector CT (EID-CT) and PCD-CT for attenuation correction and anatomical imaging.

Conditions

  • Head and Neck Cancer (H&N)

Interventions

OTHER

PCD-CT

A direct qualitative comparison of the subjective PET image quality will be performed. Two blinded board-certified radiologists/nuclear medicine physicians will independently review PET images constructed using non-contrast PCD-CT data as well as PET images constructed using standard of care non-contrast EID-CT data in random order. Both raters will assess PET images subjectively regarding overall image quality using a five-point Likert scale. The rating will be defined as: (1) non-diagnostic - insufficient diagnostic confidence, (2) poor - low diagnostic confidence, (3) moderate - average diagnostic confidence; (4) good - high diagnostic confidence, and (5) excellent - full diagnostic confidence.

OTHER

PET CT

To compare the subjective image quality of PET images constructed using non-contrast PCD-CT image data to PET images constructed using conventional standard-of-care non-contrast EID-CT image data by performing a qualitative analysis of diagnostic confidence as determined by board-certified radiologists/nuclear medicine physicians during image review.
