Prenatal diagnosis of hypospadias with 2-dimensional and 3-dimensional ultrasonography

Prenatal Diagnosis of Isolated Hypospadias by Using “Tulip Sign” with Two and Three-Dimensional Ultrasonography

Hypospadias is an anomaly of the male urogenital tract which occurs as a result of deficient closure of the urethral groove. Hypospadias is the most commonly seen urogenital anomaly in male neonates, but it is rarely diagnosed during prenatal period. Herein, a severe hypospadias case which was diagnosed by using 2D (two-dimensional) and 3D (three-dimensional) ultrasonography at 28 weeks of preg...

Inter-observer agreement between 2-dimensional CT versus 3-dimensional I-Space model in the Diagnosis of Occult Scaphoid Fractures

  Background: The I-Space is a radiological imaging system in which Computed Tomography (CT)-scans can be evaluated as a three dimensional hologram. The aim of this study is to analyze the value of virtual reality (I-Space) in diagnosing acute occult scaphoid fractures.   Methods: A convenient cohort of 24 patients with a CT-scan from prior studies, without a scaphoid fracture on radiograph, ye...

Prenatal Diagnosis of a Fetus with Ring Chromosomal 15 by Two- and Three-Dimensional Ultrasonography

We report on a prenatal diagnosis of ring chromosome 15 in a fetus with left congenital diaphragmatic hernia (CDH) and severe intrauterine growth restriction (IUGR). A 31-year-old woman, gravida 2 para 1, was referred because of increased nuchal translucency at gestational age of 13 weeks. Comprehensive fetal ultrasound examination was performed at 19 weeks revealing an early onset IUGR, left C...

Prenatal diagnosis of pentalogy of cantrell with craniorachischisis by three-dimensional ultrasonography in the first trimester.

Computer-aided diagnosis for 3-dimensional breast ultrasonography.

HYPOTHESIS Using 3-dimensional (3-D) over 2-dimensional (2-D) ultrasonographic (US) images of the breast represents a potentially significant advantage for computer-aided diagnosis (CAD). BACKGROUND Although conventional 2-D US images of the breast are increasingly used in surgical clinical practice, 3-D US imaging of the breast, a newly introduced technique, can offer more information than 2...
