Bow-tie sign: absent
Multiple sagittal T1 weighted
images reveal loss of the normal bow-tie appearance of the meniscus (black arrow). The "absent bow tie
sign" is another good sign of a bucket
handle tear of the meniscus. The absence of the normal bow-tie is secondary to the displaced fragment which makes up the
"handle" of the bucket. Requirement
for the absent bow tie sign mandates that the normal requirement of at least two adjacent sagittal images with a normal
meniscal body segment appearance is
not present.
