Reliability of contact-thermogram reading services.

Contact thermography has been advocated by some as a rapid, noninvasive diagnostic modality in evaluating patients at risk for breast cancer. In order to study the value of different criteria for interpreting thermograms, two sets of contact thermograms from 34 patients with benign breast disease were submitted to two different reading services. The results suggest that interrater agreement is enhanced when thermograms are classified as "normal" and "abnormal" rather than as class I-V.
