| description | Objective
To assess the influence of subjective enhancement of brightness and contrast of digital panoramic radiographs on the detection of soft tissue calcifications.
Materials and Methods
In this observational study, 500 digital panoramic radiographs were evaluated by two examiners in consensus, who scored the images for the presence of calcifications for each right and left side of the image. After 30 days, all images were revaluated under subjective manipulation of digital brightness and contrast. Calcifications were classified based on the diagnostic hypothesis: sialolith, tonsillolith, calcified atheroma, phlebolith, rhinolith, maxillary sinus antrolith, synovial chondromatosis, lymph node calcification, stylohyoid ligament, triticeous cartilage, or/and upper horn of thyroid cartilage calcification. For intra‐examiner agreement, 20% of the sample was reevaluated. The Kappa test and McNemar test were used (α = 0.05).
Results
In original images, calcifications were observed in 44.2% of the patients, and in enhanced images, this number was 70.8%. Many calcifications were detected only in enhanced images, mainly in the diagnostic hypotheses of calcified atheroma and stylohyoid ligament. Intra‐examiner agreement was excellent for the detection of soft tissue calcifications (0.82) and for the classification (0.81).
Conclusion
Subjective enhancement of brightness and contrast alters the detection of soft tissue calcifications in digital panoramic radiograph. |
