Establishment and Initial Testing of a Medium-Sized, Surgically Feasible Animal Model for Brucellar Spondylodiscitis: A Preliminary Study

Table 1

Modified classification of Brucellar spondylodiscitis for MRI [17].

Classification	MRI characteristics
Discitis	Regional inflammation involving intervertebral disc
	Disc space narrowing
	Low signal on T1-weighted image mixing high signal on T2-weighted image
Spondylitis	Regional inflammation involving adjacent vertebrae
	Vertebrae diffuse marrow edema
	Homogeneous or uneven low signal on T1-weighted image of vertebrae
Paraspinal/psoas abscess	Regional inflammation involving paraspinal or psoas
	Paravertebral abscess
	Psoas abscess
Appendicitis	Regional inflammation involving appendicitis
	Low signal on T1-weighted image
	High signal on T2-weighted image
Compound	Endemic inflammation involving two or more parts of vertebral and paravertebral structures
	T1-weighted image reveals incomplete heterogeneous hypointensity
	T2-weighted image reveals hyperintensity
