After induction, images of the rectus abdominis muscle were monitored with LOGIQ e®(GE healthcare, Tokyo, Japan).
b Axial FS T2-w TSE image shows an additional strain of the rectus femoris muscle without a tear, depicted as hyperintensity surrounding the central musculotendinous junction at the mid-portion of the muscle (arrow).
The coronal image demonstrates discontinuation of the reflected head of the rectus femoris at the proximal musculotendinous junction (arrow).
a, b Axial and (c) coronal STIR images demonstrate a complete tear of the reflected head of the rectus femoris with surrounding haematoma.
a Sagittal and (b) axial STIR images show diffuse intramuscular hyperintensity, consistent with contusion injury of the rectus femoris, vastus lateralis and vastus intermedius muscles.
At 5-month follow-up, (d) sagittal and (e) axial FS T2-w images show focal, full-thickness tendon disruption involving the deep tendon of the rectus femoris muscle (arrows).
Figure 1 shows typical examples of high and low EIs of the rectus femoris muscle.
defined additional ROIs on the TE = 8.6 ms multi-echo image of the first coronal slice posterior to the globe, for the four rectus muscles bilaterally using the ITK-SNAP software [ 10].
The fascia of the rectus muscles is thin posteriorly but becomes thick as the muscles approach the eye.
The superior oblique muscle arises near the rim of the optic foramen and somewhat nearer the nose than the origin of the rectus medialis.
