Qualitative Slow Blood Flow in Lower Extremity Deep Veins on Doppler Ultrasound: Quantitative Assessment and a Preliminary Evaluation of Correlation with Subsequent DVT Development in a Tertiary Care Oncology Center

Objectives To determine whether qualitative sonographic appearance of slow deep venous flow in the lower extremities correlates with quantitative slow flow and an increased risk of deep venous thrombosis (DVT) in oncology patients.
