Imaging of Tendons and Bursae Radiology Key
WebMagic angle artifact is most common just before the entrance of the tendon into the intertubercular groove where the tendon and collagen fibers are closest to the magic angle of 55 degrees relative to the main magnetic field. Magic angle artifact typically involves a short segment of the LHBT with well-defined increased signal on short TE images. WebMagic angle artifact prominent as tendons pass beneath fibula • Tendinopathy: Increased signal intensity in thickened tendon, but < fluid signal on fluid-sensitive sequences • … WebMar 1, 2004 · When 3cos 2 θ − 1 = 0 (θ = 55°, 125°, etc. approximately, the magic angle), dipolar interactions are minimized with the result that the T2 relaxation times of these tissues are increased and signal intensity may become evident within them when they are imaged with conventional pulse sequences. erika booth political party
