请关注胆囊健康

随着健康体检的普及,超声检查已成为体检中不可或缺的项目,很多疾病在超声检查下常被“逮个正着”,其中胆嚢结石和胆嚢息肉就是其中最常被发现的两种疾病。胆囊结石胆囊结石是怎么形成的胆汁的主要成分有胆固醇、胆汁酸、卵磷脂、胆红素等,正常状态下,它们的比例适当,呈黏稠的液态,颜色是墨绿色,无固体成分出现。     

双氧水与声诺维三维输卵管超声造影对输卵管通畅度的诊断价值

目的比较双氧水与声诺维三维输卵管超声造影(3D-Hy Co Sy)对输卵管通畅度的诊断价值。方法回顾分析我院经阴道超声引导下行输卵管造影检查的24例不孕症患者(共47条输卵管)的影像资料,所有病例均行双氧水造影和3D-Hy Co Sy。3D-Hy Co Sy检查前行子宫输卵管碘油造影(HSG),以HSG检查结果作为评估输卵管通畅度的金标准,对比两种超声造影诊断输卵管通畅度的优缺点。结果 1与HSG诊断结果比较,3D-Hy Co Sy对输卵管通畅度的诊断符合率为80.9%,双氧水造影对输卵管通畅度的诊断符合率为59.6%,差异有统计学意义(P﹤0.05)。3D-Hy Co Sy的假阳性率为5.3%,低于双氧水造影(47.4%);3D-Hy Co Sy的假阴性率为14.3%,高于双氧水造影(3.6%)。23D-Hy Co Sy判断近端输卵管狭窄及梗阻部位结果与HSG高度一致(Kappa值分别为0.77、0.90),双氧水造影为基本一致(Kappa值分别为0.40、0.45)。3D-Hy Co Sy判断中远端输卵管狭窄及梗阻部位结果与HSG高度一致(Kappa值分别为0.70、0.80),双氧水造影与HSG一致性差(Kappa值分别为0.31、0.31)。结论双氧水造影与3D-Hy Co Sy检查安全无创、操作简便,但双氧水造影较3D-Hy Co Sy假阴性率低,3D-Hy Co Sy可更清晰地显示输卵管立体形态结构,准确评估输卵管的通畅度及确定梗阻部位;两者结合有望提高输卵管超声造影的诊断准确率。     

花洒也需要常洗澡

<正>我们每天都用淋浴花洒洗澡,但很少有人想过给它也"洗洗澡"。花洒使用一段时间后,不仅会发生堵塞、出水不畅现象,还藏匿了大量细菌。所以,定期清洁花洒很有必要。美国科罗拉多大学的研究人员曾对5个州的45个花洒进行了取样化验。结果发现,几乎每个花洒中都藏匿着数万个细菌,其中三成检测出可导致肺病的鸟分枝杆菌,它喜欢在     

心脏彩色多普勒超声心动图监测右胸小切口房缺封堵术与右心导管房缺封堵术对比研究

目的探讨评价右胸小切口房缺封堵术与右心导管房缺封堵术的优缺点。 方法43例房间隔缺损（ASD）患者中，21例行介入手术ASD封堵术，22例行右胸小切口ASD封堵术。介入手术ASD封堵术是在大型数字减影血管造影机（DSA）下进行，经胸超声心动图监测封堵器的位置，观察有无残余分流，是否影响二尖瓣及主动脉瓣的功能。右胸小切口ASD封堵术是在手术室进行，无体外循环，完全由超声心动图监测整个过程。 结果21例行介入手术ASD封堵术者成功19例，22例行右胸小切口ASD封堵术全部封堵成功，其中包括腔静脉型房缺3例。 结论房间隔缺损封堵术有2种方式，一是右胸小切口经超声心动图全过程指导放置封堵器，二是经右心导管在DSA下放置ASD封堵器。两者比较介入疗法放置封堵器对患者创伤小，但对30mm以上大房缺及腔静脉型房缺封堵器放置不易成功。而外科微创手术对这些难治型ASD封堵更有优势。

超声造影在肾透明细胞癌检出和诊断中的应用

Background Renal clear cell carcinoma （RCCC） is the most common malignant renal tumor. It is highly malignant, does not cause clinical symptoms in its early stages, and cannot be diagnosed using conventional ultrasound. This study was aimed to investigate the contrast-enhanced ultrasound （CEUS） mode and characteristics of the time-intensity curve for RCCC and its pathological basis.
Methods Forty-two patients with pathologically diagnosed RCCC underwent CEUS examination before surgery. The patients＇ kidneys were visualized after injection of contrast agents using the Technos MPX DU8. We analyzed the CEUS mode, time-intensity curve, and pathological findings.
Results The detection rate of RCCC with conventional ultrasound was about 71%, while the rate using CEUS was 100%. Larger tumors （33 cases） showed non-uniform enhancement with defective filling. CEUS modes were divided into 4 types： type Ⅰ, ＂quick in and out＂ （26.19%, 11/42）; type Ⅱ, ＂quick in and slow out＂ （40.48%, 17/42）; type Ⅲ, ＂Simultaneous in and out＂ （16.67%, 7/42）; and type Ⅳ ＂slow in and out＂ （16.67%, 7/42）. All types had a close correlation to the pathological basis. Time-intensity curve of CEUS consisted of 3 phases, the perfusion phase, regression phase, and lag phase. Cases of types Ⅰ and Ⅲ only had a perfusion and regression phase, those of type Ⅱ and Ⅳ had a perfusion phase, regression phase, and lag phase. Quantitative analysis of the time-intensity curve showed that the time-to-peak （FTP） of the lesions was shorter than that of normal renal parenchyma （P 〈0.0001）, the mean value of the up slope rate of the absolute value of lesions was higher than that of the ipsilateral normal renal parenchyma （P 〈0.0001）, and that the mean value of descent slope rate of the absolute value of lesions was lower than that of the ipsilateral normal renal parenchyma （P 〈0.0001）.
Conclusions CEUS is useful in detecting small vessels in tumors. Although there are several different CEUS modes, type Ⅰ ＂quick in and out＂ and type Ⅱ ＂quick in and slow out＂ accounted for the most cases that had a close correlation to pathologic angiogenesis. Time-intensity curves also showed some special characteristics. These data could provide valuable information for the clinical diagnosis of RCCC.
