The present study aims to evaluate the outcome of thrombolysis for acute DVT using the thrombus signal characteristics generated by a T1-weighted MR black-blood thrombus imaging (BTI) technique.The patients were divided into iso- or hyper-intense thrombus groups according to the BTI images and the additional CDT were performed .The thrombolysis ratio of patients with iso-intense signals was significantly higher than hyper-intense ones .However, the patients with iso-intense thrombus had a lower incidence rate of PTS at 6 and 12 months.So,the thrombus signal characteristics on BTI images maybe used to predict the outcome of DVT treated with the lytic therapy.
