The current clinical application of positron emission tomography (PET)in cardiology,neurology and oncology is reviewed. PET in the cardiology has gained clinical acceptance with regard to 2indications:1. the detection of perfusion abnormalities by qualitative and semiquantitative analyses ofperfusion images at rest and stress; 2. to distinguish viable myocardium from non viable left ventricularsegments after myocardial infarction. PET studies have shown that cardiac morbidity and mortality isincreased in patients...

The current clinical application of positron emission tomography (PET)in cardiology,neurology and oncology is reviewed. PET in the cardiology has gained clinical acceptance with regard to 2indications:1. the detection of perfusion abnormalities by qualitative and semiquantitative analyses ofperfusion images at rest and stress; 2. to distinguish viable myocardium from non viable left ventricularsegments after myocardial infarction. PET studies have shown that cardiac morbidity and mortality isincreased in patients with flow-metabolic mismatches. Surlval in these patients can be significantly improvedby myocardial revascularization. PET brain imaging is better able to track the actual sequence ofpathophysiological changes and is important to the issue of patient management in acute ischemic stroke.PET is useful for the detection and evaluation of a variety of dementia. PET can identify metabolicabnormalities associated with epileptic fool and is useful in directing surgical intervention for the control ofrefractory .complex partial epilepsy. PET studies of D2 dopamine receptors demonstrates decreased uptake within the hasal ganglia of Parkinson's patients. An increased number of D2 receptors in the caudate andputamen can be found in patients with untreated schizophrenia. The amouat of available dopamine receptorsdemonstrated on PET imaging will be used to identify the respond to neurolcptic therapy. The value ofPET in clinical oncology has been demonstrated with stUdies in a variety of cancers. PET can be applied asan impobot tool for grading tumors,detecting recurrent tumors and metastasis, monitoring therapeuticeffects. FDG imaging may also provide prognostic information. The unique imaging capabilities of PETenable physicians to observe and to measure a disease process from a different perspective.

正电子发射断层图(PET)不仅能反映人体解剖结构改变,更重要的是可以提供体内功能代谢信息,从分子水平揭示疾病发病机理和治疗效应,是临床诊断心脑疾病和肿瘤的重要手段。现将其在临床应用进展介绍如下:IPET心肌显像原理和临床应用和其它脏器不同,心肌细胞为满足其?..

Objective: To observe the changes of serum soluble P selectin (sP selectin) in acute ischemic stroke and transient ischemic attack(TIA) patients and the effect of bartroxobin on it. Methods: sP selectin was measured in 16 consecutive patients (within 6 hours, 1,3,7 days after stroke) with acute ischemic stroke, in 8 patients with TIA(within 1 day after attack),in 14 patients with acute ischemic stroke after treatment with bartroxobin by enzyme linked immunosorbent assay (ELISA)....

Objective: To observe the changes of serum soluble P selectin (sP selectin) in acute ischemic stroke and transient ischemic attack(TIA) patients and the effect of bartroxobin on it. Methods: sP selectin was measured in 16 consecutive patients (within 6 hours, 1,3,7 days after stroke) with acute ischemic stroke, in 8 patients with TIA(within 1 day after attack),in 14 patients with acute ischemic stroke after treatment with bartroxobin by enzyme linked immunosorbent assay (ELISA). Results: Serum sP selectin in patients with acute ischemic stroke was increased within 6 hours, on the first day, the third day and the seventh day,especially within 6 hours and the first day. There was no significant difference between TIA patients and controls, between stroke patient treated with bartroxobin and without bartroxobin. There was no significant correlation between sP selectin levels and the extent of neurological deficits. Conclusion:Serum level of sP selectin is elevated in acute ischemic stroke and these changes are correlated with the time after stroke.

目的 :观察可溶性 P-选择素 (s P-选择素 )在急性缺血性脑卒中和短暂性脑缺血发作 (TIA)患者中的变化及巴曲酶对其的影响。方法 :用酶联免疫吸附法对 16例卒中患者在发病后 6 h,1,3和 7d连续测定 ,8例 TIA患者发病 1d内测定 ,14例卒中患者予巴曲酶治疗后血清中 s P-选择素水平测定。 结果 :急性缺血性脑卒中患者血清中 s P-选择素升高 ,在发病后 6 h和1d时最明显 ;TIA患者无变化 ;巴曲酶治疗对其无影响 ;s P-选择素水平与神经功能缺损程度无关。结论 :缺血性脑卒中急性期 s P-选择素升高 ,且与发病后的时间有关。

Objective:To investigate the incidence of cerebral arterial microemboli signal(MES)in patients with acute ischemic stroke.Methods:one hundred and fifteen patients with acute ischemic stroke of middle cerebral artery(MCA)were investigated by bilateral MCA transcranial Doppler(TCD)monitoring for 30 60(41 98±9 03)min, using 2 MHz bigated probes within 5h 7d(3 39±1 52d)after onset of symptoms Results:MES were detected in 4 34% of patients MES were more prevalent in territorial infarcts(11 11%)than...

Objective:To investigate the incidence of cerebral arterial microemboli signal(MES)in patients with acute ischemic stroke.Methods:one hundred and fifteen patients with acute ischemic stroke of middle cerebral artery(MCA)were investigated by bilateral MCA transcranial Doppler(TCD)monitoring for 30 60(41 98±9 03)min, using 2 MHz bigated probes within 5h 7d(3 39±1 52d)after onset of symptoms Results:MES were detected in 4 34% of patients MES were more prevalent in territorial infarcts(11 11%)than small infarcts(6%)and TIA(3%) No MES were found in lacunar infarcts MES were more prevalent in patients with potential emboli source(9%) and more frequent in patients with intracranial arterial stenosis(12 5%)and cardiogenic embolism (10 34%) Conclusion:It is believed that the incidence of MES in Chinese with acute ischemic stroke was significantly lower than that in west countries MES were more prevalent in territorial infarcts than in small infarcts,TIA and lacunar infarcts The main causes of MES in Chinese with acute ischemic stroke were intracranial arterial stenosis and cardiogenic embolism,not carotid stenosis.

目的 :观察中国人急性缺血性卒中患者脑动脉微栓子信号 (MES)的发生率及其临床意义。方法 :采用双门深经颅多普勒 (TCD)监测 115例大脑中动脉 (MCA)区急性缺血性卒中患者双侧 MCA血流中的 MES。结果 :MES阳性发现率为 4.34 % ,在大血管脑梗塞组 (11.11% )高于小血管脑梗塞组 (6 % )和 TIA组 (3% ) ,在腔隙性脑梗塞组未发现 MES。 MES阳性发现率在有潜在的栓子来源的患者 (9% )高于无栓子来源的患者 (0 % ) ,在颅内动脉狭窄组 (12 .5 % )和心源性栓子来源组 (10 .34 % )高于颈部颈动脉狭窄组 (0 /8)。 6 2例未能确定微栓子来源的患者无一发现 MES。结论 :中国人急性缺血性卒中患者的脑动脉 MES阳性发现率明显低于欧美文献报告 ,MES阳性率在大血管脑梗塞组高于小血管脑梗塞、TIA和腔隙性脑梗塞组 ,MES主要来源于颅内动脉狭窄和心源性栓子 ,而不是欧美人常见的颈部颈动脉狭窄
