The utility of three-dimensional surface imaging (3DSI) for measuring breast volume in the upright position has not been established.
First, the accuracy of 3DSI measurements was evaluated using plastic models with known breast volumes. Then, the breast volumes of 30 patients were measured using 3DSI in the upright position, computed tomography (CT) in the supine position, magnetic resonance imaging (MRI) in the prone position, and mammography (MMG) of the compressed breast. To determine the impact of 3DSI measurements, the correlation coefficients between 3DSI and CT, between MMG and CT, and between MRI and CT were calculated.
The accuracy of 3DSI measurements was confirmed using plastic models. The correlation coefficients between 3DSI and CT, between MRI and CT, and between MMG and CT were 0.83, 0.997, and 0.84, respectively. Although the breast volume measured by 3DSI was closely associated with that measured by CT, this correlation was weaker than that between the MRI- and CT-measured volumes and comparable with that between the MMG- and CT-measured volumes.
3DSI can be used to measure breast volume in the upright position with clinically acceptable accuracy for the evaluation of cosmetic surgical outcomes.
三维表面成像（3DSI）在直立位测量乳房体积的实用性尚未得到证实。
首先，使用已知乳房体积的塑料模型评估3DSI测量的准确性。然后，对30例患者在直立位使用3DSI、仰卧位使用计算机断层扫描（CT）、俯卧位使用磁共振成像（MRI）以及对压缩乳房进行乳房X线摄影（MMG）来测量乳房体积。为确定3DSI测量的影响，计算了3DSI与CT之间、MMG与CT之间以及MRI与CT之间的相关系数。
使用塑料模型证实了3DSI测量的准确性。3DSI与CT之间、MRI与CT之间以及MMG与CT之间的相关系数分别为0.83、0.997和0.84。尽管3DSI测量的乳房体积与CT测量的乳房体积密切相关，但这种相关性弱于MRI与CT测量体积之间的相关性，且与MMG与CT测量体积之间的相关性相当。
3DSI可用于在直立位测量乳房体积，其准确性在临床上可接受，用于评估美容手术效果。
