Original descriptions of the ossification stages defined by Vieth et al. [18]. Bold text highlights relevant differences between the stages

Stage	Type of sequence	Original descriptions
Stage 2	T1	A continuous band of intermediate signal intensity is visible, walled by serrated lines of low to no signal intensity towards the epiphysis and the diaphysis
	T2	The epiphysis is demarked by a serrated line of low to no signal intensity. The metaphysis shows two serrated lines of high signal intensity. Both lines can be continuous or discontinuous
Stage 3	T1	A discontinuous band of intermediate signal intensity is visible. The band is walled by serrated lines of low to no signal intensity towards the epiphysis and the diaphysis that sporadically convene and interrupt the band, forming a single serrated line with no signal intensity
	T2	The metaphysis shows two serrated lines of high signal intensity that sporadically convene, forming a single thin and serrated line of high signal intensity
Stage 4	T1	A discontinuous thin and serrated line of intermediate signal intensity between the epiphysis and the diaphysis is visible. In the continuity of the line, thicker sections with no signal intensity can be seen
	T2	A thin single, discontinuous or dotted line of hyperintense signal is visible in the same position as the described thin line of the corresponding T1-w sequence. In the continuity of the line, thicker hyperintense sections can be seen
Stage 5	T1	A continuous thin line of intermediate signal intensity between the epiphysis and the diaphysis is visible
	T2	A single thin, discontinuous or dotted line of hyperintense signal in the same position as the described thin line of the corresponding T1-w sequence
Stage 6	T1	A continuous thin line of intermediate signal intensity between the epiphysis and the diaphysis is visible
	T2	No hyperintense signal in the same position as the described thin line of the corresponding T1-w sequence
