==Diagnosis== [[File:CT of Schmorl's nodes.jpg|thumb|[[CT scan]] in the [[sagittal plane]] of two Schmorl's nodes. The small Schmorl's node at the inferior endplate of the L3 vertebral body (arrow) has typical features, being broad-based at the endplate, with well-defined contours and thin marginal sclerosis. A large and less typical Schmorl's node (arrowhead) is observed at the superior endplate of L4.<ref name="Nogueira-BarbosaCrema2015">{{cite journal |last1=Nogueira-Barbosa |first1=Marcello Henrique |last2=Crema |first2=Michel Daoud |last3=Herrero |first3=Carlos Fernando Pereira da Silva |last4=Pasqualini |first4=Wagner |last5=Defino |first5=Helton Luiz Aparecido |title=The Several Faces of Schmorl's Node: Pictorial Essay |journal=Coluna/Columna |date=December 2015 |volume=14 |issue=4 |pages=320–323 |doi=10.1590/S1808-185120151404151248 |doi-access=free }}</ref>]] Schmorl's nodes can be detected with X-rays, although they can be imaged better by [[Computed tomography|CT]] or [[MRI]]. They are considered to be vertical [[spinal disc herniation|disc herniations]] through the cartilaginous vertebral body endplates. Schmorl's nodes can sometimes be seen radiographically, however they are more often seen on MRI, even when not visible on plain X-rays. They may or may not be symptomatic, and their etiological significance for back pain is controversial. In a study in Spine by Hamanishi, et al., Schmorl's nodes were observed on MRI in 19% of 400 patients with back pain, and in only 9% of an asymptomatic control group. The authors concluded that Schmorl's nodes are areas of "vertical disc herniation" through areas of weakness in the endplate.<ref>{{cite journal |doi=10.1097/00007632-199402001-00012 |pmid=8178234 |title=Schmorlʼs Nodes on Magnetic Resonance Imaging |journal=Spine |volume=19 |issue=4 |pages=450–3 |year=1994 |last1=Hamanishi |first1=Chiaki |last2=Kawabata |first2=Tutomu |last3=Yosii |first3=Takeo |last4=Tanaka |first4=Seisuke |doi-access=free }}</ref>
