1.Mutual Benefit of Imagiological Methods in the Acute Truma of Thoracic and Lumbar Spine
Journal of Practical Radiology 1991;0(03):-
Objective To discuss the matual benefit of imagiological methods of thoracic and lumbar spine.Methods There were 129 cases with acute truma of thoracic and lambar spine,CT and trditional X-ray wee done in all cases,of them MRI were performed in 27 cases.Results In 129 cases fracturesof the vertebral body were in 144 with totally 156 regicns,of that,84 were injury of spinal canal and 72 were spinal canal stenosis.27 cases performed by MRI,all stewed spinal cord injury.Conclusion In acute truma of the thoracic or lumbar vertebral column, traditional X-ray is a basic method,CT is of mutaral benefi,while MRI is the best to diagnose spinal cord injury.

Objective To discuss the applied value of diffusion weighted imaging(DWI) in evaluating emboliza-tion effect of transcatheterhepatic arterial chemoembolization(TACE) for Hepatic Metastases. Methods DWI was performed in 17 Hepatic Metastases patients at the next day after TACE. Embolization effect was analyzed andcompared with DSA results. Results 17 lesions were revealed in DSA anA with complete iodinated oil accumulation,9with incomplete accumulation. 47 lesions were revealed in DWI and 33 with complete iodi, a oilaccumulation,9 with in-complete accumulation,5 without iodinated oil accumulation.The area of iodinated oll accumulation and necrosis appeared aslow signal on DWI,and residual tumor tissues appeared as high signal. Conclusion DWI may detect Hepatic Metastases lesions sensitivelyand can be used to evaluate the embolization effect of TACE.

Objective To discuss the applied value of MSCT in the interventional treatment of hepatic metastases (HMs). Methods 23 cases HMs were treated by interventional treatment before it MSCT plain scan was performed first,and then dual-phase dynamic contrast-enhanced scanning and reconstruct angiography. Results 78 lesions were found by plain scan,and 102 lesions in the arterial phase and 105 lesions in the portal venous phase were found by contrast-enhanced scan,dynamic contrast-enhanced CT scanning was superior to detecting lesion of diameter <1cm (P<0.05). CT scanning showed that plain scan showed low-density foci; and according to the number of enhanced lesions,enhancede scanning showed enhancement for the edge of the ring,diffuse enhancement,heterogeneous enhancement,and no enhancement respecfly. Vascular remodeling showed that all eases could show the hepatic artery three grade below through MSCTA,eompletely conformed to the DSA,the indication rate was 100%;14 cases could show the hepatic artery four grade above,with 60.9% indication rate. Portal vein showed that all cases could show the branches of intrahepatic portal vein four grade below through MSCTA; DSA hepatic arteriography could show the portal vein indirectly,but most of the intrahepatic branches three grade below couldn't show clearly. Conclusion MSCT dynamic contrast-enhanced scan could improve the detection rate of HMs,and dynamic contrast-enhanced scanning was superior to the detection rate then plain scan,high-qulity imagy of hepatic artery and portal vein could be reconsructed by fast dynamic contrast-enhanced scanning,and compared with DSA,it had the advantage of operat more easily and non-invasive,so as be a guide in the interventional treatment of HMs.

Objective To investigate effect of Murphy's law on the nursing safety management of the hemodialysis patients. Methods 4598 hemodialysis cases in a blood purification center of a first class grade A hospital from April to July in 2011 was assigned as pre-implementation group.Then Murphy's law was used in the nursing practice.In the following,another 5683 hemodialysis cases from November in 2011 to January in 2012 were assigned as post-implementation group.The incidence of nursing risks and hemodialysis equipment failures were compared between the two groups.Result The incidences of nursing risks and hemodialysis equipment failures in the post-implementation group were significantly lower than those of the pre-implementation group(P<0.05).Conclusions Murphy’s law is effective for the declines of nursing manipulative defects and hemodialysis equipment failures.Besides,the law can be good for the strengthened awareness of safety and enhanced consciousness of all staff participating in the safety management so as to ensure the safety and quality of hemodialysis.
