What is it at L3? Pars Stress Fracture?

Note STIR and T1 images

Atypical Hemangioma

Fat is bright on T1 images but water is black

On STIR images, fat is suppressed but water is still bright

In this case, the bright pedicle on T2 images is bright on T1 but not suppressed on STIR

This means it is fluid, an atypical hemangioma

Can be confused as a stress fracture
