Evaluation of ischemic lesions after carotid artery stenting with diffusion-weighted imaging.

Background: Almost 90% of cerebral thromboembolism cases are caused by atherosclerosis. Craniocervical atherosclerosis is often observed at the carotid bifurcation and is responsible for 20%-30% of all stroke cases. The course of atherosclerotic carotid artery stenosis varies depending on the grade of stenosis and characteristics of the plaque.

Frequency and imaging findings of variations in human aortic arch anatomy based on multidetector computed tomography data.

The purpose of this study was to describe the frequency of the variations in the branching pattern of the aortic arch (AA) according to multidetector computed tomography (MDCT) imaging findings. MDCT images of 1136 consecutive patients who had undergone imaging of the chest were retrospectively examined. Eleven different branching patterns were observed.

Quantitative MRI analysis of idiopathic carpal tunnel syndrome.

Aim: The aim of this study was to try to find parametric ratios for the diagnosis and pathophysiology of carpal tunnel syndrome using MR.

Material And Methods: Dominant side wrist MRI examinations of 27 female carpal tunnel patients and 21 normal females were compared. The carpal tunnel contents area / carpal tunnel cross section area ratio was defined, analysed and discussed with the literature.

Spontaneous third ventriculostomy in chronic obstructive hydrocephalus.

Introduction: Spontaneous ventriculostomy is a rare condition, and only few cases are reported. Cine magnetic resonance imaging can demonstrate the flow from the ventriculostomy.

Case Report: A 25-year-old woman with a known tectal glioma and hydrocephalus was proved to have spontaneous third ventriculostomy.

Computed tomography virtual laryngoscopy: comparison between radiological and otolaryngological evaluations for laryngeal carcinoma.

Objectives: We evaluated the utility of computed tomography virtual laryngoscopy (CTVL) in identifying endolaryngeal lesions in laryngeal tumors.

Patients And Methods: Virtual laryngoscopic images were obtained from axial CT scans of 21 patients with known laryngeal carcinoma. Findings from rigid telescopic videolaryngoscopy (RTV) and CTVL images were evaluated and compared with reference to operative records.
