Abstract:
Purpose To explore the consistency and clinical value of ultrasound and MRI in the diagnosis of giant cell tumor of tendon sheath(GCTTS)in extremities.Materials and Methods A retrospective analysis was performed on 35 patients who came to the First Affiliatted Hospital of Gannan Medical University from January 2020 to December 2022 due to hand-foot masses,and underwent ultrasound and MRI examination,which were confirmed by surgery or puncture cytology.Taking pathological results as the"gold standard",the sensitivity,specificity and positive likelihood ratio were compared,and the consistency and clinical value of the diagnostic classification of the two examination methods were further analyzed.Results Among the 35 cases of hand-foot masses,17 cases were diagnosed of GCTTS by ultrasound,16 cases were diagnosed of GCTTS by MRI,and 15 cases were diagnosed of GCTTS by pathologically.Ultrasound and MRI were consistent in the diagnostic classification of hand-foot masses in 30 cases and were inconsistent in diagnostic classification in 5 cases,and the diagnostic classification of the two mehtods was strongly consistent(Kappa=0.714).The sensitivity,specificity and coincidence rates of GCTTS in extremities diagnosed by ultrasound were 73.3%,70.0%and 71.4%,respectively.Those of GCTTS in extremities diagnosed by MRI were 80.0%,80.0%and 80.0%,respectively.Those of GCTTS in extremities diagnosed by ultrasound combined with MRI were 86.7%,70.0%and 77.1%,respectively.There were no significant differences in the diagnostic accuracy among ultrasound,MRI,ultrasound and MRI combined diagnosis and pathological examination(P>0.05).There were no significant differences in sensitivity,specificity,and positive likelihood ratio among ultrasound,MRI and the combined diagnosis of hand-and foot masses(P>0.05).Conclusion Ultrasound and MRI have good consistency in the classification and diagnosis of GCTTS in extremities.There was no significant difference between ultrasound and MRI in the overall diagnostic performance of GCTTS in extremities.
