Measurement of bony Orbital Volume with Computed Tomography (CT) in Healthy Eyes of Saudi Children
ثبت نشده
چکیده
The bony orbit surrounding the eye is pyramidal with a rectangular base. The orbital volume (OV) of an adult is approximately 30 mm3 [1]. However, measurement of OV can be inconsistent due to the complicated anatomical structure of the bony orbit including the irregular inner border, holes and fissures. Computed tomography (CT) provides excellent image quality of bony landmarks making it a popular imaging technique for viewing orbital pathology. Additionally, CT is accurate and reproducible, due to the 3-dimensional image capabilities [2].

Estimation of radiation dose to the lens of eyes of patients undergoing cranial computed tomography in a teaching Hospital in Osun state, Nigeria
Background: One of the means of assessing dose to patients from Computed tomography (CT) procedure is through the determination of the skin entrance dose (ESD) with the appreciation of the concern that ocular exposure effects from CT scan includes possible induction of cancer and cataract. Due to the relatively more recent introduction of CT scans, little work has been done in this area in the ...
متن کامل3-D computed tomography reconstruction: another tool to teach anatomy in the veterinary colleges
This letter underpins the use of three-dimensional computed tomography (3D-CT) reconstruction as an aid to teach veterinary anatomy. Cases were presented to students in order to observe normal and clinically abnormal patients. The images provided excellent details of relevant structures and could serve as a tool for teaching anatomy. Many sources describe different options to enhance anatomical...
متن کاملBony orbital development after early enucleation in humans.
AIM To analyse the extent of bony orbital volume reduction after enucleation in humans. METHODS Volumetric studies on bony orbital volumes based on three dimensional reconstructions acquired from high resolution computed tomograph (CT) scans were performed in 29 patients with acquired anophthalmia and four patients before enucleation (controls). Eight patients (follow up 25-52 years) were enu...

INTRODUCTION This article reports experience relating to the measurement of orbital volume by means of cone beam computed tomography (CBCT) and Cranioviewer program software in patients who have undergone enucleation and orbital implantation. PATIENTS AND METHODS CBCT scans were made in 30 cases, 10 of which were later excluded because of various technical problems. The study group therefore ...

Introduction: Orbital metastasis of prostate cancer (PC) is very rare and even more unique in castration-resistant PC (CRPC). In this scenario, choline positron emission tomography/computed tomography (choline PET/CT) is the gold-standard restaging method of choice available in our setting, and new anti-androgens treatments show improvement in overall survival. Case presentation: We report the...
