Point-of-care musculoskeletal ultrasound and magnetic resonance imaging of suprapatellar recesses in the knees. Longitudinal MSKUS image (a) of the unaffected knee was compared to the affected knee (b), which showed semicompressible hypoechoic contents (white arrow) in the suprapatellar recess. T2-weighted (c) and T1-weighted (d) MRI showed hyperintense (white arrows), corresponding to blood clots. MSKUS, musculoskeletal ultrasound; MRI, magnetic resonance imaging.
