Comparison of diagnostic information in TUI volume datasets acquired with B-mode imaging only or B-mode plus color Doppler imaging (n=168)

Plane of section	Perfect agreement between B-mode and color Doppler imaging in classifying views as normal, abnormal, or not diagnostic	Color Doppler modified the initial diagnostic impression by B-mode imaging only	No contribution of color Doppler to B-mode imaging	Kappa	P value by McNemar test
Four-chamber view	85.7% (145/168)	12.5% (21/168)^*	1.8% (3/168)	0.537	0.135
Five-chamber view	83.9% (141/168)	14.2% (24/168)^†	1.8% (3/168)	0.431	0.004
Three-vessel view	75% (126/168)	10.1% (17/168)^‡	14.8% (25/168)	0.370	0.172

In 3 cases, non-diagnostic four-chamber views were adequately visualized with color Doppler; 4 false-positive and 14 false-negative diagnoses by B-mode imaging were corrected by color Doppler.

^†

In 17 cases, a five-chamber view considered to be of no diagnostic value was adequately imaged by color Doppler; 6 false-positive and 1 false-negative diagnoses by B-mode imaging were corrected by color Doppler.

^‡

In 13 cases, a three-vessel view considered to be of no diagnostic value was adequately imaged by color Doppler; 1 false-positive and 3 false-negative diagnoses by B-mode imaging were corrected by color Doppler.
