It is observed that as long as either type of pattern in the object is persistent between the times the unknown impression and the known impression are captured, an attempt to determine origin can be made by a trained and experienced examiner who understands patterns and their images.
Control subjects (n = 22) demonstrated diagnostic motion symmetry as determined by a trained, experienced examiner.
Gerwin et al. [26] found that these criteria, when applied by an experienced examiner, have good inter-examiner reliability (kappa) ranging from 0.84 to 0.88.
That is why to avoid the possible interobserver bias only one experienced examiner performed all examinations.
Cross-sectional images were collected by a single experienced examiner, who continued each examination until highly reproducible scans were obtained.
The lesions that were difficult for the students to score (ICDAS) could have surprised even an experienced examiner by their depth.
In the present study, we have found a lack of clinical utility of HE4 serum concentrations assessment in patients with ovarian tumors which are suspicious and difficult to classify correctly in subjective ultrasonography examination performed by an experienced examiner.
The clearly improved diagnostic ability compared to the previous study (Troelsen et al. 2007) indicates that a learning curve may be associated with the use of ultrasound in acetabular labral tear diagnostics, in this case even for the experienced examiner who did all ultrasound examinations in both studies.
All clinical exams were performed by an experienced examiner, a PhD student (GMLF) who had previous experience in cross-sectional data.
The examiners had no previous experience of this specific test, but they were well trained by an experienced examiner, from pilot testing preceding the present study.
SD-OCT examinations were performed in all eyes by a single experienced examiner (EV) using Spectralis (Heidelberg Engineering, Heidelberg, Germany) SD-OCT, which provides up to 40000 A-scans per second with 7 μm depth resolution in tissues and 14 μm transversal resolution of images of ocular microstructures.
