Abstract:
Objective To explore the image quality of 3.0 T Magnetic Resonance foot and ankle array coil on Achilles tendon ab-normalities for the clinical application.Methods 26 patients (with Achilles tendon symptoms)and 5 volunteers underwent MR exam-ination.The scanning sequences were used:T1 WI、PDWI、T2 WI-FS and STIR.Image diagnoses and clinical data of all patients were obtained and analyzed.Subjective scores on image quality were used.Degrees of comfort in coil were evaluated.Results 10 patients had Achilles tendon inj ury,6 patients with Achilles tendonitis,3 patients with part Achilles tendon rupture,1 patient with tendon xanthoma,and 6 patients were normal.Image scores in patients with T1 WI、PDWI and T2 WI-FS sequences were higher,the anatom-ic structures,lesions of whole Achilles tendon were clear.On the contrary,the lower scores were in STIR sequences.In the heel, images were distorted,the level of organization was disappeared and signal intensity was increased.The volunteers felt a slight dis-comfort at the coil entrance and support point of the heel.Conclusion Patients using 3.0T foot and ankle array coil for the Achilles tendon scanning could get high image quality and degrees of comfort.
