Table 2: Tomtec and Ventripoint-derived algorithms for left ventricular
and left atrial volumes: relationship with body surface area
Absolute and percentage differences are calculated as VMS -Tomtec.
Indexing: TT LVEDV: BSA^1.05172. VMS LVEDV: BSA^1.1937558. TT
LVESV: BSA^1.1630229, VMS LVESV: BSA^1.15831. ULOA Upper limit of
agreement. LLOA Lower limit of agreement: Represents Average ± 1.96 x
SD. VMS: Ventripoint software VMS 3.0, TT: Tomtec Image Arena, LV: left
ventricle, LA: left atrium, EDV: end diastolic volume, ESV: end systolic
volume, EF: ejection fraction, BSA: body surface area. 95% CI
Ninety-five percent confidence intervals (1.96 SD +/- mean), Ln: natural
logarithm.
