Abstract
Background and Purpose—
The Tada (ABC/2) formula has been used widely for volume assessment of intracerebral hematoma. However, the formula is crude for irregularly shaped hematoma. We aimed to compare the accuracy of the ABC/2 formula with open source software Slicer.
Methods—
Computed tomographic images of 294 patients with spontaneous intracerebral hematoma were collected. Hematoma volumes were assessed with the ABC/2 formula and calculated with software 3D Slicer. Results of these 2 methods were compared with regard to hematoma size and shape.
Results—
The estimated hematoma volume was 58.41±37.83 cm
3
using the ABC/2 formula, compared with 50.38±31.93 cm
3
with 3D Slicer (mean percentage deviation, 16.38±9.15%). When allocate patients into groups according to hematoma size, the mean estimation error were 3.24 cm
3
(17.72%), 5.85 cm
3
(13.72%), and 15.14 cm
3
(17.48%) for groups 1, 2, and 3, respectively. When divided by shape, estimation error was 3.33 cm
3
(9.76%), 7.19 cm
3
(18.37%), and 29.39 cm
3
(39.12%) for regular, irregular, and multilobular hematomas.
Conclusions—
There is significant estimation error using the ABC/2 formula to calculate hematoma volume. Compared with hematoma size, estimation error is more significantly associated with hematoma shape.
