It is obtained by integrating many two-dimensional (2D) acquisitions into a volume to form a multiplanar reconstruction.Four-dimensional imaging: volumetric images obtained over a period of time.Coronal plane: the plane perpendicular to the sagittal and transverse planes that demarcates anterior and posterior portions of three-dimensional (3D) structures.Three-dimensional inversion display: a “cast” is formed of the cystic areas within a volume while the solid areas are made “lucent.” This forms a positive display of anechoic structures, which can be combined with color Doppler data to also visualize fluid or blood flow within.
