MRI evaluation of meniscal anatomy: which parameters reach the best inter-observer concordance?

Purpose: The aim of the study is to evaluate which MRI parameters achieve the best degree of inter-individual concordance in the description of meniscal fibrocartilage, regarding its morphology, signal and position.

Materials And Methods: Eighty-nine knee MRIs were included in the study, retrospectively re-evaluated by three radiologists who completed a binary report (normal/abnormal) describing the meniscus signal, position relative to the tibial plateau margin and morphology. The inter-individual concordance value was calculated using Cohen's test.

Inter-observer concordance in normal and pathological findings of the hip joint in plain radiographs.

Background And Aim: The purpose of the study was to compare the data obtained by two independent observers and statistically analyze the results using Cohen's K to highlight the concordance or discordance in the diagnosis of normality, pathology and, in particular, the type of femoro-acetabular impingement (FAI) on plain films.

Methods: the study was conducted retrospectively. The only inclusion criterium was the minimum age of 20 years.
