Three-dimensional CT maximum intensity projections of the calvaria: a new approach for diagnosis of craniosynostosis and fractures.
نویسنده
چکیده
Three-dimensional CT maximum intensity projection (MIP) can depict suture patency, extent of synostosis (ie, complete versus incomplete bone bridging), fracture extent and conspicuity, and 3D calvarial deformity as a single set of projections in children with suspected craniosynostosis or skull fracture. Three-dimensional CT MIP may provide, in only eight views, all the required information to make the diagnosis of craniosynostosis and calvarial fracture extent currently requiring the combined information of 3D CT shaded surface displays and 2D axial CT images (a total of 58 views), and in some cases complementary skull radiographs. Three-dimensional MIP can be added to calvarial helical (spiral) CT imaging with only 5 minutes of additional postprocessing time.

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...

Adnexal masses are spectrum of diseases from benign non neoplastic and neoplastic masses to malignant neoplasms. Endovaginal ultrasonography (US) is the fisrt and invaluable modality for assessment of adnexal masses because it is available and has a high negative predictive value. Important morphologic features are solid (vascularized) tissue, vascular and thick septations, and papillary projec...

In children with suspected cranial pathologies, three-dimensional (3D) computed tomography (CT) imaging is superior to other modalities. It can help differentiate actual pathology from normal or variant appearances.
