Magnetic resonance imaging and ultrasonographic evaluation of retinal detachment in orbital uveal melanomas.

We assess the role of ultrasonography (US) in the evaluation of retinal detachment in patients with uveal melanomas, in correlation with magnetic resonance imaging (MRI) findings. Twenty-six patients (13♂ and 13♀) with uveal melanomas underwent MRI and US examination. The signal intensity of the tumors and retinal detachments were depicted using MRI.

Orbital cavernous hemangiomas: ultrasound and magnetic resonance imaging evaluation.

Cavernous hemangioma is the most common intraorbital lesion in adults. The aim of our study was to evaluate the magnetic resonance imaging (MRI) and ultrasound (US) characteristics of cavernous hemangioma and their role in the differential diagnosis of orbital tumors. Eight patients with orbital cavernous hemangiomas, five women and three men with a mean age of 48 years were examined in a period of six years.

Craniosynostosis : correlation with cranial vault shape and osseous defects.

This study assessed the value of three-dimensional CT (3D CT) in the diagnosis of craniosynostosis, and correlated the cranial deformity with the presence of osseous defects in cranial vault's bones. One hundred and two children (55♀ and 47♂) with a clinical suspicion of craniosynostosis, underwent spiral computed tomography with 3D reconstruction using the shaded surface display (SSD) and volume rendering (VR) algorithms. We evaluated the presence of osseous defects in cranial bones in correlation with the type of craniosynostosis and the shape of the cranial vault.
