Results
The study sample was comprised of 10 (40%) females and 15 (60%) males.
Patient’s age at the moment of diagnostic procedure ranged from 30 to 73 years with mean of 57.32 years (SD 9.27).
The longest period between baseline and follow-up examination was 31 weeks while the shortest was 24 weeks,
averagely 25.6 weeks.
The results demonstrated almost perfect agreement in baseline assessment and reassessment of the all three readers (p<0.001) (Table 1).
Similarly,
the applied statistics could not identify disturbances in both series of follow-up measurements considering all observers (p<0.001) (Table 2).
The calculated ICC values demonstrated almost perfect agreement in baseline readings (Table 3) between both the first and second radiologist (p<0.001) as well as the first radiologist and the first-year resident (p<0.001) or the second radiologist and the first-year resident (p<0.001).
Similarly,
the almost perfect agreement was estimated in follow-up readings (Table 4) between the experienced radiologists (p<0.001) as well as in separate analyses between both radiologist and the first-year resident (p<0.001).
