Deep Learning for Accurate Segmentation of Venous Thrombus from Black-Blood Magnetic Resonance Images: A Multicenter Study

Figure 1

Representative images are obtained by BTI from four DVT patients. Images are shown with the same window and level, and the value on the arrow represents the signal intensity. (a) Different signal intensities of the thrombus (red arrows) can be observed in a patient; (b) the thrombus (red arrows) can distribute in a large area from the common iliac vein to the popliteal vein; (c) the thrombus (red arrow) may have very similar signal intensity with the adjacent muscle (green arrow); (d) iliac tissues (blue arrow) may have the similar signal intensity and shape with the thrombus (red arrow).
