SUBJECTS ANDMETHODS. … WebIncreased signal intensity on magnetic resonance (MR) imaging of tendons arising from the magic angle phenomenon is well recognized. This study aimed to evaluate the effect of varying the echo time (TE) upon tendon signal intensity, and to determine if a modified TE value produces acceptable T1 and proton density (PD) weighted images.
WebMar 25, 2024 · The Harvard physicists also show that the principal magic angle can be very precisely calculated and that its value is the same as that reported in experiments. They believe that exotic magic-angle phenomena could occur in other van der Waals layered devices, and they are now actively investigating these systems. WebIn the present study, we examined whether this appearance could be accounted for by the "magic-angle" phenomenon resulting from the angular orientation of this meniscal segment relative to the static magnetic field. Fifty-eight consecutive knee MR examinations were studied. Sixteen were excluded because of frank evidence of preexisting ...
