Interobserver and intraobserver variability were calculatedand expressed as percent average value.
Bidimensional ultrasonography steatosis grading is subjective and subject to interobserver and intraobserver variability.
For this reason, we decided to compare interobserver and intraobserver agreement between thoracicand general radiologists.
Flow and velocity in the pulmonary arteries, as well as left and right cardiac output, can be measured with low interobserver and intraobserver variability.
A previous study by our group showed high interobserver and intraobserver agreement for the E' and A' measurements.
In order totest the applicability of the MRADL, as well as its reproducibility, a study is being conducted to assess its internal validity by determining interobserver and intraobserver variability.
Overall, echocardiography and CMR interobserver and intraobserver agreements were excellent Table 5.
In the diagnosis of NAFLD, the calculation of the SHRG presented a high accuracy in the group of studied adolescents,suggesting that such a method can reduce the high interobserver and intraobserver variability.
For calculation of interobserver and intraobserver reproducibility, a set of 24 patients were used twelve benign and twelve malignant.
An adequate validation process must test psychometric properties and analyze internal consistency, interobserver and intraobserver reproducibility and validity.
Subsequently, the interobserver and intraobserver agreement were evaluated for the quantification of the bronchiectasisand its associated findings on the HRCT scans.
The evaluation of HRCT scans for ILDs relies on the subjective interpretation of images and the recognition of abnormal patterns,which are associated with interobserver and intraobserver variations.
In order to assess interobserver and intraobserver reproducibility, we used the intraclass correlation coefficient ICC, values greater than 0.75 being considered excellent.
The results of the present study demonstrate that,in the HRCT evaluation of patients with bronchiectasis, interobserver and intraobserver agreement was generally moderate for each tomography finding in isolation.
The kappa index(k)(9,15) was utilized to measure interobserver and intraobserver agreement, according to Chart 2, comparing, respectively, data from each pair of observers, and data from each observer for the same parameters obtained at different moments.
The impact of clinical information, the observer expertise and the confidence level for the diagnostic hypotheses on the interobserver and intraobserver agreement in the diagnosis of ILDs based on HRCT scans are important issues that have not been fully evaluated.
The results indicated excellent interobserver and intraobserver reproducibility, with a high degree of response agreement between different administrations, suggesting that the items are clear and reduce possible biases on the part of the observers, as demonstrated by Leon et al.
The interobserver and intraobserver performed more than 5 months after the original analysis agreements were assessed using intraclass correlation coefficients, ICC; using a two-way random effect model, absolute agreement, and average measurement with 95% confidence intervals, and Bland-Altman plots for continuous variables, and Cohen's kappa coefficient for categorical variables.
Kappa statistics were used to calculate the interobserver and intraobserver reproducibility, all with a confidence interval of 95%, as well as simple agreement to measure the cases with a small number of disagreements.
In conclusion, interobserver and intraobserver agreement on the diagnosis of ILDs based on HRCT scans in our population ranged from fair to almost perfectand was highly influenced by the expertise of the radiologists, the clinical information provided and the level of confidence for the diagnostic hypothesis.
In conclusion, we observed only moderate interobserver and intraobserver agreement in the evaluation of the tomography findings of bronchiectasis, when evaluated in isolation. However, in the final analysis of the findings, there were no significant changes in the classification of the severity of bronchiectasis for each patient.
The aim of this study was to determine the interobserver and intraobserver agreement on the diagnosis of ILDs based on HRCT scans, as well as to evaluate the influence of the observer expertise, the confidence level and the clinical history of patients on the observer agreement, comparing two experienced thoracic radiologists with two young general radiologists who have received basic training in HRCT.
A total of 600 analyses were performed to assess the intraobserver, interobserver and intersoftware agreements.
Analysis of the reproducibility and intraobserver and interobserver reliabilities was tested through three simultaneous tests: the PABAK, the ICC and the Bland-Altman tests, as shown in Table 2.
