The final sample consisted of 45 individuals,
of which 15 (33.3%) were radiology students and 30 (66.7%) Radiographers (Table 1).
In order to verify the reliability of the questionnaire Cronbach's alpha test was performed (α = 0.803).

To calculate the sensitivity values (S),
specificity (E) and Acuity (A) all the responses were analyzed.
Using Microsoft Excel software we calculated the sensitivity,
specificity and acuity for each individual.
An average value was obtained for each group,
as can be seen in Table 2.

Specificity and Accuracy for the various dependent variables.

Looking at Table 4,
there is no statistically significant relationship between the detection of pathologies with each of the study variables,
except for muscle rupture,
i.e.,
the detection of this condition is influenced by variables Professional Experience and Training.
On average students take 33.53 seconds to respond to each case and technicians took 37.17 seconds.
Fisher's test was applied and the results are shown in Table 4.
