Routine ultrasonography in patients with breast tumors is useful for determining if tumors are benign or malignant.
We attempted to improve three-dimensional (3-D) ultrasonography of breast tumors. Ultrasonograms using conventional mechanical arc scanning equipment (7.5 MHz, Aloka SSD 270) were obtained at 1 and 2 mm intervals transversely and recorded on videotape.
The ultrasonographic images on the videotape were input into a minicomputer, and the breast tumor shape was graphically displayed in three dimensions. The 3-D images of breast cancer had jagged margins that could be evaluated more clearly than the original ultrasonogram.
This finding suggests that the 3-D ultrasonogram has the potential to differentiate malignancy from benign tumors better than ordinary ultrasonography.
