Patients with acute deep vein thrombosis (DVT) can be characterized as iso- or hyper-intense thrombus signals using a T1-weighted black-blood magnetic resonance imaging (BTI) technique. Patients with hyper-intense thrombus signals demonstrated a significant higher incidence of post-thrombotic syndrome (PTS) than those with iso-intense thrombus signals, regardless of the patient’s age, gender, the severity of DVT, and the treatment strategy of catheter-directed thrombolysis or conventional anticoagulant therapy. The results suggest that the thrombus signal characteristics obtained on BTI imaging are valuable for assessing the prognosis of acute DVT and may aid in guiding the clinical treatment plan.
