There are many diagnostic methods: plain X-ray, tomogram, computed tomogram (CT scan), myelography, CT-myelography (CTM), and magnetic resonance imaging (MRI). Each imaging method suggests various information about ossification of the posterior longitudinal ligament (OPLL) and ossification of the yellow ligament (OYL).
