Purpose:
We prospectively evaluated the validity of total and viable residual splenic volume after partial splenic embolization (PSE) with three-dimensional (3D) ultrasound (US) measurement.
Methods:
Twenty patients with splenomegaly were included. All splenic volumes were measured with transabdominal US using virtual organ computer-aided analysis (VOCAL). The viable residual splenic volume after PSE was estimated by using contrast-enhanced (CE) US with VOCAL. The agreement of the measurements from VOCAL and computed tomography (CT) was confirmed using interclass correlation coefficients (ICCs) and Bland-Altman plots.
Results:
Mean volume was 503 ± 250 ml for total spleen and 209 ± 108 ml for viable residual volume. Regarding total volume, there was a high correlation and agreement (ICCs = 0.90) between 3D US and CT volumetry. Regarding viable residual volume, although there was a moderate correlation between 3D CEUS and CT volumetry, mean ICCs of 0.617 indicated poor agreement. With Bland-Altman plots, a narrow 95 % limit of agreement was observed among patients with a total volume under 1000 ml.
Conclusion:
The total splenic volume could be accurately estimated with 3D US. However, estimation of viable residual splenic volume should be limited in cases with total splenic volume under 1000 ml.
