Normal values for cardiovascular magnetic resonance in adults and children

Table 19 Right atrial diameter in the adult for the SSFP technique according to reference [22]

Parameter	mean	SD	Lower/ upper limits*
Longitudinal diameter (cm) 4ch	5.5	0.58	4.3-6.7
Longitudinal diameter/BSA (cm/m²) 4ch	3.0	0.32	2.4-3.6
Transverse diameter (cm) 4ch	4.7	0.55	3.6-5.8
Transverse diameter/BSA (cm/m²) 4ch	2.6	0.3	2.0-3.2
Longitudinal diameter (cm) 2ch	5.4	0.5	4.4-6.4
Longitudinal diameter/BSA (cm/m²) 2ch	2.9	0.3	2.3-3.5
Transverse diameter (cm) 2ch	4.3	0.7	2.9-5.7
Transverse diameter/BSA (cm/m²) 2ch	2.4	0.4	1.6-3.2

BSA = body surface area; SD = standard deviation; * = calculated as mean ± 2*SD; 4ch = 4-chamber view; 2ch = 2-chamber view; since no influence of gender was demonstrated, gender specific values are not presented.
