The intravertebral vacuum cleft: a sign of ischemic vertebral collapse.
A gas-density cleft within a transverse separation of the vertebral body, appearing in extension and disappearing in flexion, was observed in 10 cases of vertebral collapse at the thoraco-lumbarExpand

Review article Magnetic resonance imaging of normal bone marrow
The appearance in magnetic resonance imaging (MRI) of the bones depends, to a large ex- tent, on the unmineralized content of the bone cav- ities. Because yellow marrow contains a large num- ber ofExpand
