The Low Field MRI Findings of Iliotibial Band Friction Syndrome

Objective:To explore the low field MRI features of the iliotibial band friction syndrome(ITBFS).Methods:The clinical and 0.35 T MRI imaging data of 12 patients with ITBFS lesions confirmed clinically were analyzed retrospectively.Results:All patients had lateral knee pain,particularly evident when running and other sports.On the acute and sub acute stage(4 cases),MRI showing the iliotibial band swelling with the increased signal,the swelling effusion located in the medial and(or) lateral of the iliotibial band;On the chronic phase(8 cases),MRI showing the thickening iliotibial band,the swelling effusion located in the medial and(or) lateral of the iliotibial band may be seen.The coronal MR imagings show the best.Conclusion:Knowing the features of clinical and low field MRI manifestations may be helpful to early diagnosis of the ITBFS.
