OBJECTIVE Our objective was to use a combination of axial MR source images and three-dimensional (3D) models to describe the anatomy of the normal pelvic floor in young nulliparous women and to measure the volume of the levator ani. SUBJECTS AND METHODS Ten healthy nulliparous female volunteers (average age, 27 years) underwent T2-weighted MR imaging of(More)
RATIONALE AND OBJECTIVES To improve the conspicuity of bladder tumors in a virtual environment, we developed an algorithm for color mapping the thickness of the bladder wall. The purpose of this study was to demonstrate the feasibility of this algorithm as a component of virtual CT cystoscopy. METHODS Five subjects with a history of superficial(More)
We assessed ten prenatal magnetic resonance imaging(MRI) scans for fetal brain anomalies, and identified eight that were suitable for post-processing. Anatomical abnormalities were assessed on three-dimensional (3D) models and compared with two-dimensional (2D) imaging. We calculated the volumes of the intracranial ventricles and of a periventricular(More)
Background. Gadolinium-enhanced three-dimensional (3D) MR angiography is a useful imaging technique for patients with congenital heart disease. Objective. This study sought to determine the added value of creating 3D shaded surface displays compared to standard maximal intensity projection (MIP) and multiplanar reformatting (MPR) techniques when analyzing(More)
OBJECTIVE In this prospective study, we aimed to assess the prognostic and diagnostic role of color Doppler flow of myometrium in patients with invasive gestational trophoblastic disease (GTD). METHODS Thirty-seven patients, who were enrolled in the study with invasive mole, were assessed with the help of transvaginal color Doppler ultrasound before and(More)
RATIONALE AND OBJECTIVES The purpose of this study was to determine the volume of the normal female cervix and to determine the geometric formula that yields the best estimate. MATERIALS AND METHODS Magnetic resonance images of the pelvis in 30 young women were reviewed retrospectively. The volume of the cervix was estimated by using the formulas for an(More)
