Objective: to compare the estimated thyroid volume, as determined by two-dimensional (2D) and three-dimensional (3D) ultrasonography, with real volume. Design: Descriptive Study Animals: A total of 7 mixed breed dogs Procedures: On 2D ultrasound, the thyroid volume is estimated by the ellipsoid equation and on 3D ultrasound; it is estimated by outlining the boundaries of the thyroid lobe in ...

  Abstract   Background: Hydronephrosis is the most common congenital condition that is detected   by prenatal ultrasonography. Moreover, the widespread use of prenatal ultrasonography   results in an increased recognition of fetal hydronephrosis. Prenatal hydronephrosis   is diagnosed at an incidence of 1:100 to 1:500 by ultrasonographic studies. The presence of hydronephrosis is not synonymou...

This study was conducted to determine the use of three-dimensional ultrasonography (3DU) in ocular imaging of the dog and measuring of its optical axis. 12 healthy mixed-breed dogs including 6 males and 6 females were studied. 3DU of the eyes were done using a 5–12 MHz linear trapezoid transducer. 3DU of the eyes were evaluated and the normal optical long axis through a line between the cornea ...

OBJECTIVE Patient characteristics, CA125 level and two-dimensional (2D) ultrasonography can be used to predict the probability of malignancy of an ovarian mass. Three-dimensional (3D) ultrasonography might also contribute to the prediction of malignancy. We evaluated whether addition of 3D features to a diagnostic model could improve the discriminative capacity of the model. METHODS This mult...

OBJECTIVES The aim of this was to evaluate the accuracy of two-dimensional (2D) ultrasonography in the diagnosis of nuchal cord to enable us determine if it can be recommended for its antenatal diagnosis. MATERIALS AND METHODS Between 01 January and 30 April 2012, 93 singletons pregnancies in cephalic presentation with 2D ultrasound scan done at term but within 24 h before onset of labor for ...

OBJECTIVE To present the variable appearance of micrognathia in fetuses by three-dimensional ultrasonography and to describe practical methods for analysis of these volume data. METHODS Three-dimensional multiplanar imaging and surface-rendering techniques were used to show various syndromes and diagnostic approaches for the evaluation of fetal micrognathia. RESULTS Nine cases of fetal micr...
