Proximal hamstring tendinopathy and partial tearing. Axial T₂ weighted image of the proximal hamstrings. The right side shows the normal hypointense appearance of the tendons of semimembranosus (anterior, black arrow) and semitendinosus and biceps femoris (posterior) near their insertions into the ischial tuberosity. On the left, there is tendinosis of the semimembranosus tendon, which is thickened and of increased intensity, with partial tearing shown as fluid signal crossing part of the tendon (white arrow). There is also fluid adjacent to the tendon.
