彩色多普勒超声在阴囊肿块的应用价值

阴囊肿块是男性常见病，其部位虽然表浅，但单凭临床触诊和透光试验有时难以判断肿块发生的部位和性质，超声检查不仅可以准确判断肿块发生的部位，还可以根据肿块内的回声及血液动力学改变、肿块与周围组织的关系推断肿块的性质。本文报告159例阴囊肿块超声检查结果，旨在探讨其应用价值。

１９９２年１０月～１９９９年２月,我们对阴囊肿块应用二维超声及ＣＤＦＩ进行检查。阴囊肿块病种较多,囊性病变由于其透声性好、结构清楚,较易明确诊断。而实质样肿块,因其声像图结构复杂,且有相似之处,较易混淆。本文就５０例超声诊断结果总结如下。１资料与方法５０例...     

The diagnosis and management of scrotal masses

When evaluating a patient with a scrotal mass, a careful history and inguinoscrotal examination are necessary. Malignant scrotal wall, paratesticular, or spermatic cord tumors are rare. Scrotal ultrasound can confirm the precise location of a mass or rule out the presence of an inguinal hernia. Testicular masses deserve a formal workup, with serum tumor markers, a scrotal ultrasound as needed, and prompt consultation with a urologist for further staging and intervention. Scrotal masses in children are much rarer than in adults and should be evaluated by a urologist.     

Slip imaging: reducing ambiguity in breast lesion assessment

Ultrasound elasticity imaging (elastography) is gaining popularity as an adjunct to B-mode ultrasound for breast cancer diagnosis. Cancerous masses are usually stiffer than normal tissue, hence, using elasticity imaging should lead to better differentiation between benign and malignant masses than using B-mode alone. Clinicians assess the mobility of masses on palpation; cancers usually being less mobile. We introduce a method to estimate mobility, called slip imaging and combine it with conventional B-mode and elasticity data. In the reported evaluation on 70 women recalled to a breast assessment clinic, images were scored by three breast radiologists independently. Diagnostic accuracy increased from 75.7% with B-mode alone, to 78.1% when including elasticity imaging, to 80.0% when further including slip imaging. Specificity increased (74.6%:75.4%:82.5% respectively), with an apparent trade-off in sensitivity (77.1%:81.3%:77.1%). We conclude that Slip imaging is potentially a useful adjunct to B-mode and elasticity imaging and should undergo further research and development.     

三种手术方式与术后残留卵巢综合征分析

目的探讨采用不同手术方式行子宫全切或次全切而保留一侧或双侧卵巢，术后残留卵巢综合征（ROS）的发生率、发病原因及诊断治疗方法。方法病例选自2002年2月-2006年2月，在我院因良性疾病行子宫全切或次全切，开腹手术531例，腹腔镜手术445例，经阴手术116例，其中发生ROS各为23、9、0例，均有明显症状，经超声证实，一旦确诊选用避孕药等治疗，门诊随访。结果开腹、腹腔镜、阴式手术ROS的发生率分别为4．3％、2．0％、0。腹腔镜手本与开腹手术比较差异有统计学意义（P〈0．05），阴式手术缺乏可比性。32例ROS中，18例药物治疗，6例B超穿刺，8例再次手术治疗。结论全子宫或次全子宫切除术保留一侧或双侧卵巢时可发生ROS，而腹腔镜手术可减少ROS发生率，阴式手术可能减少ROS的发生，一旦确诊先用抑制卵巢的药物治疗，无效时可选用B超穿刺和手术治疗，再次手术以腹腔镜首选。     

彩色多普勒超声对阴囊闭合性损伤的诊断价值

目的探讨彩色多普勒超声对阴囊闭合性损伤的诊断价值。方法回顾性分析32例阴囊外伤患者的彩色多普勒超声图像资料,检测阴囊壁层次结构和睾丸的形态大小,内部有无肿块;对病变区,测量其大小,观察其形态、边界及内部同声,并用彩色多普勒观察肿块内部及周边血流情况。结果32例患者根据睾丸、阴囊的声像图表现可分为：睾丸挫伤5例,睾丸血肿10例,睾丸破裂16例,单纯阴囊壁血肿1例（另有10例阴囊壁血肿合并睾丸损伤）。结论高频彩色多普勒超声能准确诊断阴囊、睾丸的损伤,可作为阴囊闭合性损伤的首选检查方法。

Ultrasound assessment of testicular and paratesticular masses

This article discusses the role of ultrasound in the workup of patients with suspected or palpable scrotal masses. By characterizing masses as intra- or extratesticular, the differential diagnosis can be narrowed considerably. Neoplasm is the primary concern with intratesticular masses, although non-neoplastic conditions, such as hematoma and focal orchitis, may have a similar appearance. Correlation with the patient's history is essential. The sonographic presentation of extratesticular pathology, including varicocele and masses of epididymal origin, is also described. © 1996 John Wiley & Sons, Inc.     

The use of contrasted transvaginal sonography in the diagnosis of gynecologic diseases: a preliminary study.

OBJECTIVE: The purpose of this study was to evaluate the efficacy of a new contrast-dedicated ultrasound technology, contrast-tuned imaging (CnTI), implemented on an endovaginal probe and using the second-generation contrast agent SonoVue (Bracco International BV, Amsterdam, the Netherlands), compared with the standard ultrasound examination in different gynecologic diseases. METHODS: Eighty-nine patients were enrolled in the study in 4 different clinical centers. The study included 40 patients with uncertain pelvic adnexal masses, 10 patients with pelvic masses indicative of recurrences of gynecologic tumors, 26 patients with uterine pathologic features, and 13 patients with cervical lesions. RESULTS: Application of CnTI technology after the SonoVue injection gave a picture of the intralesional microvascularization dramatically different from that obtained during color Doppler examination. Of the 40 pelvic masses, 15 (37.5%) were considered benign and 25 (62.5%) were considered malignant at B-mode and color Doppler examinations. Contrast-enhanced sonography showed no intralesional contrast perfusion in 11 (73%) of 15 cases, and all these were benign at final diagnosis. Of the 4 (27%) cases that had perfusion, 2 were malignant. Conversely, of the 25 cases with positive findings at color Doppler examination and therefore expected to show the appearance of contrast tissue-filling morphologic characteristics, 13 (52%) were malignant at final diagnosis. For evaluation of uterine pathologic features, the CnTI-SonoVue technology did not appear to be superior to the B-mode and color Doppler examinations; however, for the evaluation of cervical cancer, CnTI-SonoVue technology revealed a better definition of the margins of the neoplastic lesions in 4 (40%) of 10 cases. CONCLUSIONS: In the evaluation of uncertain pelvic masses, the CnTI technology led to an improvement in the ability of the practitioner to differentiate benign from malignant adnexal lesions.     

B超早期诊断转移性肝癌与螺旋CT的对比研究

目的通过与螺旋CT对比,探讨B超在转移性肝癌早期诊断中的应用价值。方法对58例随访期恶性肿瘤患者,每1个月复查上腹部CT、肝脏B超以及其他必要检查,比较肝脏B超和上腹部CT检测转移性肝癌病灶的符合率以及对门静脉癌栓检出率的差异,观察转移性肝癌在B超下的影像学特点。结果58例患者中,有32例出现肝转移,其中29例由肝脏B超和上腹部CT同时发现转移病灶,符合率为90.6%;B超的门静脉癌栓检出率明显高于CT(P=0.026)。结论肝脏B超在一定程度上可以替代螺旋CT作为恶性肿瘤随访过程中检测肝转移的影像学手段。
