| 1 | Fisher判别在孤立性肺结节CT鉴别诊断中的应用显示文摘目的:探讨Fisher判别模式对孤立性肺结节CT鉴别诊断的应用价值。方法:回顾性分析了149例孤立性肺结节患者的CT资料,按病理随访结果分为良性组和恶性组两大类,对结节主要CT形态学特征进行评价,按良、恶性分组,以两组间有统计学意义的形态学征象为判别指标并行Fisher判别,采用交叉核实法估计误判概率。结果:孤立性肺结节CT征象的Fisher判别公式为Z=-0.251×1+0.563×2-0.319X3+0.261×4+0.492×5-0.101×6+0.326×7+0.329×8,误判率为12.08%,敏感性为89.32%,特异性为84.78%,鉴别诊断的准确率达87.92%。结论:Fisher判别模式能够有效的对孤立性肺结节进行鉴别诊断,具有较高的临床实用价值。 | 徐钐 周四清 温生贵 | 2010 | 医学影像学杂志2010，20，12： | 5 |
| 2 | 胃间质瘤的螺旋CT诊断显示文摘目的 分析胃间质瘤(GST)的CT表现及其诊断价值.方法 回顾性分析10例经手术病理证实为GST患者的CT检查资料,行CT平扫者10例,CT平扫和增强扫描者5例.结果 肿块向腔外生长者较多(6/10),表现为类圆形或分叶状肿瘤;发生于胃窦部1例,胃体部6例,胃底部1例,贲门2例.10例GST中,良性3例,肿块直径多<5 cm,密度较均匀,边界清楚,均匀强化;恶性7例,肿块直径多>5 cm,密度多不均匀,边界可清楚或不清楚,强化不均匀;6例肿块内有坏死.10例均行手术后光镜观察及免疫组化检查,10例CD117均为阳性,7例CD34阳性.结论 CT检查对于GST的定位准确及定性诊断有重要价值. | 王金周 焦俊 闫瑞芳 熊建国 | 2010 | 中国实用医刊2010，37，6： | 1 |
| 3 | IMAGING TECHNIQUES FOR THE DIAGNOSIS OF RENAL TUMORS显示文摘In recent years.diagnostic imaging techniques,especially ultrasonography (US) and CTscanning,have been widely adopted in clinical practice,making early accurate diagnosisof renal tumors possible.A total of 452 cases of renal tumors have been admitted to theinstitute since 1951,of which 220 were seen from 1951 to 1979 and 232 in the past 9years (1980-1988).The frequency of renal parenchymal tumors was obviously higher in thelatter group,including asymptomatic renal carcinoma in 20.2% and hamartoma in 38.1%.All these were discovered on routine physical check-up by ultrasonography and/or CTscanning and would otherwise have gone undiagnosed on conventional urography.Ultra-sonography and CT can also reveal the nature and the extent of the tumor.The idea that“a renal tumor should be considered malignant unless pathologically proven otherwise”isno longer valid.However,general manifestations of renal carcinoma,such as elevatederythrocyte sedimentation rate (ESR),hypertension,malaise,anemia,fever and hypercalcemia,still deserve proper attention.We suggest that ultrasonography of both kidneys should bemandatory in routine physical check-up,as far as the urinary system is concerned,in orderto discover asymptomatic renal tumors. | 顾方六 | 1990 | Chinese Medical Sciences Journal1990，8，2： | 0 |
| 4 | CLINICAL OBSERVATION ON ELECTRO-ACUPUNCTURE TREATMENT OF 51 CASES OF PROTRUSION OF LUMBAR INTERVERTEBRAL DISC显示文摘Through electroacupuncture(EA) treatment of 51 cases of protrusion of lumbar interver-tebral disc, it was further demonstrated that the specific action and characteristics of Siyao and Wuyao acupoints were significant and elucidated by using some objective indexes and obvious therapeutic ef-fect, which lays a foundation for the development, research, popularization and application of shu-point and provides an effective and practicable way for treatment of lumbar intervertebral disc. | 韩友栋 江亦泉 王秀英 | 1997 | World Journal of Acupuncture-Moxibustion1997，7，4： | 0 |
| 5 | Arterial phase of biphase enhancement spiral CT in diagnosis of small hepatocellular carcinoma显示文摘Objectives: To evaluate the value of the arterial phase(AP) of biphase enhanced spiral CT(SCT) in the di-agnosis of small HCC and to investigate the criteria,initial time, ending time and duration of AP.Methods: From May 1995 to March 1999, patients withsmall HCC proved surgically and pathologically in-cluding 49 patients (n=53) in group A, 148 (n=186) ingroup B and 52 (n=52) in group C were collected.Biphase dynamic enhanced SCT scans were performedin all patients of the three groups and additional sin-gle-level dynamic scans only done in the group C. Thedetectability, diagnostic accuracy of lesions and en-hancement of the lesions in AP were analyzed statisti-cally. In addition, the initial time, ending time andduration of AP were measured.Results: The results of the group A showed the de-tectability of small HCC was 88.68% in AP and90.57% in both phases, higher than those by ultra-sound. Markedly enhanced lesions in AP accounted for76% and 78% in the groups B and C respectively. Theinitial time, ending time and duration of AP measuredon single-level dynamic scans were 16.9s, 39.6s and22.7s on average respectively.Conclusions: The biphase dynamic SCT especially itsarterial phase appears to be very valuable in diagnosingsmall HCCs. In light of short duration of AP, under-standing and strict control of AP is obviously impera-tive. | Kang-Rong Zhou Fu-Hua Yan Bei-Wu Tu From the Department of Radiology, Zhongshan Hospital, Fudan University, Shanghai, 200032, China | 2002 | Hepatobiliary & Pancreatic Diseases International2002，1，1： | 0 |
