Biological characteristics of the cerebral venous system and its hemodynamic response to intracranial hypertension.

Background: The role of the cerebral venous system (CVS) in intracranial pressure (ICP) regulation remains largely unclear. In the present study, the interaction between ICP and the cerebral venous system and its possible mechanism were investigated with respect to the biological characteristics of the cerebral venous system and its hemodynamic response under increased ICP.

Methods: We created intracranial hypertension animal model, measured and calculated the venous flow velocity and diameter of the outflow terminal of the CVS with color ultrasonic system and recorded the vascular morphology by 3-dimensional anatomical microscopy.

Diagnostic value of dual-source CT in Kawasaki disease.

Background: Doppler color echocardiography is a common method for detecting coronary artery lesions in patients with Kawasaki disease (KD). However, the diagnostic accuracy for the whole coronary artery lesions is limited. The purpose of this study was to compare the diagnostic value of dual-source computed tomography (DSCT) and Doppler color echocardiography for the assessment of coronary artery lesions caused by KD.

Clinical application of 64-slice spiral CT in the diagnosis of the Tetralogy of Fallot.

Objective: To explore the clinical application of 64-slice spiral CT in the diagnosis of the Tetralogy of Fallot.

Methods: Eighteen patients with diagnosed Tetralogy of Fallot underwent cardiac CT angiography with 64-slice CT (CTA). Two- and three-dimensional images were used for diagnosing in all cases by means of MPR (coronal, sagital and oblique), cMPR, MIP and VRT.

[CT multiplan reconstruction images of disorder of stapes].

Objective: To evaluate the clinical application of multi-planar reformation (MPR) for the stapes with multi-slice spinal thin-section CT in the patients with disorder of stapes before prosthetic ossicular reconstruction and their impact on surgical decision.

Methods: Axial CT scanning of temporal bone was undergone in 50 volunteers. Multiplan reformatted images included coronal, sagittal and oblique MPR, were made.
