Abstract
The liver tumors represent a major pathology in the medical practice, considering their high incidence, the
diagnostic difficulties and the high rate of morbidity and mortality.
Ultrasonography remains the main imaging method for diagnosing liver tumor masses. This position is sustained by the large addressability of the investigation, its noninvasive and, consecutively, repetitive character and the lower price.
Three-dimensional ultrasound (3D US) is an increasingly important area of ultrasound development. 3D US exploits the real-time capability of ultrasound to build a volume that can then be explored using increasingly affordable high performance workstations.
The continued clinical acceptance of 3D US depends on three broad areas: these are volumetric data acquisition, volume
data analysis and volume display.
3D ultrasonography, using the “multiplanary” and “quad
mode”, allows the precise location on the three axes of the liver
tumors and the accurate estimation of distances from the main vascular structures of the liver to the tumors (important for the surgeons).
The rotation of the acquired volume and of the area of interest shows more efficiently the spatial relationships between the tumor masses and the surrounding structures.
