by producing undistorted three-dimensional images of the area under examination, cone-beam computed tomography (cbct) systems have met many of the limitations of conventional radiography. these systems produce images with small field of view at low radiation doses with adequate spatial resolution that are suitable for many applications in endodontics from diagnosis to treatment and follow-up. t...

computed tomography (ct) is now the primary diagnostic method for head trauma because of its ability to demonstrate the nature, extent, sites, and multiplicity of brain injuries. although there have been numerous reports on the ct findings of most types of intracranial injury, the findings in brainstem injury have not been well described. this study aimed at comparing the autopsy findings of br...

background: ct scan and nuclear medicine exams deliver a great part of medical exposures. this study examined professional radiation hazards in ct scan and nuclear medicine workers.   methods : in a cross sectional study 30 occupationally exposed workers and 7 controls (all from personnel of a laboratory) were selected. physical dosimetry was performed for exposed workers. blood samples were ob...

The pineal gland is very important human endocrine gland and its location and size is very important for the neurologist and neurosurgeons and for the radiologist because in certain radiological investigations it is the guide of midline and its right or left shifting is highly suggestive of space occupying lesion in the brain. The aim of study was to find out the morphometric parameters of pine...

Recently, the usefulness of three-dimensional CT angiography (3D-CTA) using helical CT has been reported. Although 3D-CTA has been applied for neurosurgical diseases, especially for surgical planning, it has not done for emergency patients because of the long time required for image reconstruction and location of a helical CT scanner. We studied emergency patients with SAH, and compared the 3D-...

This case report presents one of the first reported uses of a 3D printed exhibit in an English homicide trial, in which two defendants were accused of beating their victim to death. The investigation of this crime included a micro-CT scan of the victim's skull, which assisted the pathologist to determine the circumstances of the assault, in particular regarding the number of assault weapons and...

Current motion capture techniques all have shortcomings when applied to the 3D quantitative evaluation of thumb base motion. Dynamic CT might overcome these shortcomings but, so far, robustness of this technique in more than one specimen has not yet been demonstrated. The aim of the current study is to further evaluate the use of dynamic CT for quantification of thumb motion in a larger cadaver...
