摘要:
目的:探讨低张饮水磁共振胰胆管造影(MRCP)结合不压脂T2WI及LAVA动态增强对十二指肠乳头腺癌的诊断价值.方法:收集资料齐全的28例十二指肠乳头腺癌患者,所有患者在常规MRCP、压脂T2WI基础上行低张饮水MRCP、不压脂轴位T2WI及LAVA动态增强扫描,比较低张饮水前后MRCP、不压脂和压脂T2WI对十二指肠乳头腺癌的显示效果,以及常规MRCP结合压脂T2WI及LAVA动态增强与低张饮水MRCP结合不压脂T2WI及LAVA动态增强对十二指肠乳头腺癌的诊断准确率.结果:28例患者中,75.0%(21/28)低张饮水后较低张饮水前肠管进一步充盈扩张,89.2%(25/28)低张饮水后胃肠蠕动较低张饮水前减弱,28.6%(8/28)低张饮水后较低张饮水前对病变梗阻部分的显示更准确,64.3%(18/28)不压脂T2WI序列对病变显示优于压脂T2WI序列,常规MRCP结合压脂T2WI及LAVA动态增强与低张饮水后MRCP结合不压脂T2WI及LAVA动态增强对十二指肠乳头腺癌的诊断准确率分别为82.1%(23/28)和92.8%(26/28).结论:低张饮水MRCP结合不压脂T2WI及LAVA动态增强对十二指肠乳头腺癌具有较高的诊断价值.

摘要:
目的 探讨低张法在胃癌CT检查前处置流程中的价值.方法 分别连续入组低张和未行低张CT扫描胃癌患者各52例.根据CT图像盲法评判胃壁各部扩张伸展的情况,轴位图像测量正常胃壁厚度,联合轴位、冠状位、矢状位观察蠕动波情况.结合各参数对图像质量主观分级.卡方检验、t检验及秩和检验比较两组CT征象及图像质量差异.结果 非低张组正常胃壁厚度大于5mm的比例高于低张组(P<0.001).非低张组蠕动波出现比例高于低张组(P=0.001).低张组图像质量分级优于非低张组(P<0.001).结论 低张是胃癌CT检查前处置的重要环节,可延缓胃排空、降低胃壁张力、减少蠕动波,使胃壁充分扩张,利于癌肿检出和范围的判断.%Objective To investigate the values of hypotonic procedures in the CT imaging of gastric cancer.Methods Fiftytwo consecutive gastric cancer patients who underwent hypotonic CT examinations and 52 consecutive patients with non-hypotonic procedure were enrolled in study.The extension degrees of various parts of gastric wall on CT were evaluated with blind method.The thickness of normal gastric wall was measured on axial plane.The appearance of peristaltic wave was observed with combination of axial,coronal and sagittal planes.The subjective image scoring was evaluated through the combination of several imaging quality parameters.Chi-square test,t-test and Kolmogorov-Smirnov test were used to determine the difference between two groups.Results The ratio of thickness larger than 5 mm in normal gastric wall in non-hypotonic group was higher than that of hypotonic group(P < 0.0 0 1).The peristaltic wave displayed more frequently and severe in non-hypotonic group than in hypotonic group (P =0.001).The hypotonic group outperformed non-hypotonic group in subjective image scoring (P < 0.001).Conclusion Hypotonia is a key procedure of gastric cancer CT examination,with which to slow stomach empty,to minimize the tension of gastric wall,to reduce peristaltic wave,to get sufficient distention of gastric wall,and to facilitate the detection of lesions and border judgment.

摘要:
Objective:To study the diagnostic value of hypotonic double contrast digital radiography ex-amination to early esophageal cancer. Method: The digital radiography examination image and pathological data of 72 cases with early esophageal cancer diagnosed in our hospital were reviewed .Then compare it with the traditional single contrast esophageal radiography examination .Result:Esophageal wall relaxation degree slightly worse , 34 cases;the local mucosal disruption and destruction , 64 cases;small filling defect , 22 ca-ses;small niche, 21 cases.The traditional single contrast esophageal radiography examination in 18.6 cases, accounting for 18.1%;the hypotonic double contrast esophageal digital radiography examination in 68 cases, accounting for 94.4%.Conclusion:Hypotonic double contrast digital radiography examination has important value in the diagnosis of early esophageal cancer , reflected in the discovery , locating , qualitative aspects .It is obviously superior to the traditional single contrast radiography examination .%目的:探讨数字化的低张双对比造影对早期食道癌的诊断价值。方法:回顾性分析我院确诊72例早期食道癌的数字化低张双对比造影的影像资料,并与传统单对比食道造影进行比较。结果:数字化低张双对比造影对72例早期食道癌的X线表现分析:食道管壁舒张度稍差,34例;局部粘膜中断破坏,64例;小充盈缺损,22例;小龛影,21例。结论:数字化的低张双对比造影对早期食道癌的发现、定位、定性具有重要诊断价值,明显优于传统单对比造影。

摘要:
目的 研究数字化处理结肠低张气钡双重造影检查,对患者早期结肠病变和癌肿的发现价值.方法 我院从2011年1月到2013年10月选择性对193例病员,男132例,女61例,年龄11岁-82岁(平均53.2岁),有不同程度的腹部疼痛、腹胀、腹泻或间歇性腹泻、便秘、便血、黑便的患者进行数字化成像结肠气钡双对比造影检查,最后检出阳性病例均以手术或病理证实.结果 本组经双重低张造影发现有病变者57例,占造影总数30%,经乙状结肠镜和治疗证明慢性炎症35例,占造影总数18%,手术及病理证实的结肠癌,男性16例,占造影总数的8%,女性7例,占造影总数的4%,其中盲肠及升结肠粘液腺癌17例,占造影总数的9%,低分化癌2例,占造影总数的1%,多发性息肉恶变2例,占造影总数的1%,肺结核合并肠结核4人,年轻人多见,占造影总数的2%.结论 数字化成像结肠双对比造影检查效果好,在早期病变的检出率最为明显.

摘要:
Objective To discuss the diagnostic value of the low Pneumobarin double contrast examination of radiography for cardia cancer. Methods Rretrospective analyzed clinical data of 45cases of gastric cardia patients who were diagnosed by low pneumobarin double contrast examination of radiography,and compared with gastroscopy and pathology diagnosis. Results The main manifestation of low pneumobarin double contrast examination of radiography of 45cases were abnormal thickening disorder and hypertrophy of the mucosa,barium contrast passed slowly through the cardiac,and cardiac spasm musosa convergence and interruption,local nodular or granular shadows of different sizes were found.Conclusion low pneumobarin double contrast examination of radiography is economic,convenient and non-invasion. And it combined with gastroscope inspection and pathological examination can improve the accuracy of diagnostic.% 目的探讨低张气钡双重造影检查对贲门癌的诊断价值。方法对45例贲门癌患者行低张气钡双重造影检查,并结合胃镜检查及病理学检查作出诊断。结果45例患者在低张气钡双重造影检查中,主要 X 线表现有黏膜异常增粗、紊乱、肥大,钡剂通过贲门缓慢、贲门痉挛,黏膜纠集、中断,局部呈结节样或大小不一的颗粒状影阴等。结论低张气钡双重造影检查经济、方便、无创,是贲门癌最直接、有效的检查方法,如果结合胃镜及病理学检查,可提高诊断准确率。
