Objective To evaluate the application of multi-slice CT angiography(MSCTA) in cerebral vascular diseases.Methods 16-slice spiral CT angiography of 32 patients which clinically suspected cerebrovascular diseases were analyzed retrospectively.Source images were processed by GE Lightspeed CT Scanner;all axial images were transferred to an external workstation.The reconstructed images were processed VR,MPR,MIP in working-station.Results 10 of the 32 patients were normal, 17 were aneurysms,could be clearly displayed with the source, size,and neck width.3 were AVM,the location and scope could be observed.2 were vaso-occlusive.Conclusion Multislice spiral CT angiography is a safe ,quick and noninvasive method in diagnosing the cerebrovascular disease,it may be proposed as a first choice technique for screening and preoperative assessment for cerebrovascular disease.CTA is a valuable diagnostic method for various intracranial cerebral disease.

We have developed a new rotating bed for the old and the paralised people. This rotating bed is composed of two bed heads at front and at end, bed boards, guardrails, an electric motor, a reducer, an induction locator and a set of electronic controls. With the preestablished program, the angle between the left/right bed board and the middle board is changed by rotating the left/right board around the rotation axis, and the gravity direction between the human body and the ground is changed by the rotation of the middle board as a whole, so that the middle bed board and the left and right ones will act respectively as supporters of weight of the person who is lying on his back or on his side. In this way, a person can turn over automatically, comfortably and naturally when he/she is asleep. This rotating bed meets the physiological needs of a sleeping person, and people with turning over problems can turn over in a comfortable and natural way by means of biotechnology. It can also improve the quality of sleep and help avoid decubitus. In addition, it can be used to promote the rehabilitation of those who are paralysed by reason of its passive exercising function.
