目的 探讨腮腺淋巴结炎继发化脓性腮腺炎的CT及声像图特点,以明确诊断,指导临床治疗。方法 对10例腮腺淋巴结炎继发化脓性腮腺炎患者进行临床资料分析,并进行CT和B超检查,分析其影像学特点。结果 腮腺淋巴结炎继发化脓性腮腺炎CT检查虽可见腺体内斑点状密度减低,密度不均,但腮腺轮廓完整:B超检查表现为腺体内点状低回声,或多个厚壁无回声区,随病变减轻,无回声区缩小并减少。结论 腮腺淋巴结炎继发化脓性腮腺炎可以通过CT及B超检查,并结合临床表现,与腮腺恶性肿瘤相鉴别,避免不必要的手术。  相似文献

The purpose of this study was to determine whether 12.5 MHz ultrasonography (US) could be used to assess the presence or absence of temporomandibular joint (TMJ) condylar osteoarthrosis. In 40 consecutive patients with TMJ disorders, 80 TMJs were investigated by US to analyse the condylar morphology. In order to compare the respective findings with those of a diagnostic method offering a high accuracy, coronal and sagittal magnetic resonance imaging was carried out immediately afterwards. With US showing a sensitivity of 87%, and a specificity of 20%, the data revealed US to be sensitive in detecting the presence, but insufficient in detecting the absence of osteoarthrosis. In addition, with a positive predictive value of 88%, and a negative predictive value of 18%, the results indicate that US may be valuable in diagnosing the presence, but insufficient in diagnosing the absence of osteoarthrosis. In view of the fact that the 12.5 MHz US technique proved to be a valuable diagnostic aid for the detection and prediction of abnormal condylar morphology, the results of this study should be of further interest and encourage research in its potential uses and diagnostic capabilities.  相似文献

The purpose of this study was to determine whether 12.5 MHz ultrasonography (US) could be used to assess the presence or absence of temporomandibular joint (TMJ) internal derangement (ID). In 48 consecutive patients with TMJ disorders 192 TMJ positions were investigated by US to analyse the functional disc-condyle relationship (DCR). In order to compare the respective findings with those of a diagnostic method offering a high accuracy, coronal and sagittal magnetic resonance imaging was carried out immediately afterwards. With US showing a sensitivity of 0.58 and 0.75, and a specificity of 0.92 and 0.84 for disc displacement with and without reduction, the data revealed US to be marginal in detecting the presence, but sensitive in detecting the absence of the respective types of a TMJ ID. In addition, with a positive predictive value of 0.83 and 0.71, and a negative predictive value of 0.81 and 0.87 for disc displacement with and without reduction, the results indicate that US may be insufficient in establishing a correct diagnosis for the presence or absence of the respective types of TMJ ID. Regarding the diagnosis of absence or presence of TMJ ID, the results demonstrate high-resolution (HR)-US to be sensitive in detecting the absence, and reliable in predicting the presence of TMJ ID. In view of the fact that the 12.5 MHz US technique proved to be a reliable diagnostic aid for the detection of normal, and the prediction of abnormal DCR, the results of this study should be of further interest and encourage research in its potential uses and diagnostic capabilities.  相似文献

超声引导下深度冷冻治疗原发性肝癌   总被引:19,自引:0,他引:19  
应用超声引导对32例原发性肝癌进行了插入式深低温冷冻治疗。全部病例术后恢复均顺利,无手术死亡及严重并发症。其中25例冷冻后肿瘤均有不同程度缩小,13例肿瘤缩小≥50%。认为深度低温冷冻治疗肝癌不仅能有效地杀灭冷冻区所有的肿瘤细胞,还能最大限度地保存正常肝组织;而且在术中B超的监测下能对冷冻的范围进行准确的控制,避免损伤肝内重要的管道系统。因此深度低温冷冻治疗对某些无法手术切除的肝癌是一种安全有效的治疗方法。  相似文献

We report a case of infarction of lesser omental fat in a 30-year-old woman who presented with epigastric pain. Sonography revealed a painful echogenic mass in the epigastrium that could not be separated from the adjacent hyperechoic pancreas and mimicked an exophytic pancreatic tumor. On CT, the mass was identified as an inflammatory lipomatous mass in the lesser sac, leading to the diagnosis of infarction of lesser omental fat. The patient was successfully treated conservatively.  相似文献

OBJECTIVE: The purpose of this study was to evaluate micro flow imaging (MFI) in depicting the vascular architecture of hepatocellular carcinoma (HCC) and the correlation between pathologic differentiation and the intratumoral vascular architecture pattern. METHODS: Micro flow imaging and contrast harmonic imaging (CHI) were performed in 37 patients with HCC. A sulfur hexafluoride-filled microbubble contrast agent was used. The enhancement level and intratumoral vessels were evaluated on CHI. The vascular architecture of each tumor was evaluated on MFI. Pathologic differentiation of the tumors was classified according to the Edmondson grading system. RESULTS: All 37 HCCs showed hyperenhancement in the arterial phase and hypoenhancement in the portal and late phases on CHI. Intratumoral vessels in the arterial phase were visualized in 20 (54.1%) HCCs. On MFI, the vascular architecture in all lesions was clearly delineated and categorized into 3 patterns: cotton, shrubbery, and deadwood, identified in 12 (32.4%), 22 (59.5%), and 3 (8.1%) of the tumors evaluated, respectively. A chi(2) test showed that pathologic differentiation significantly correlated to the vascular pattern (P = .006). Three (75%) of 4 Edmondson grade I HCCs showed the cotton pattern; 18 (75.0%) of 24 Edmondson grade II HCCs showed the shrubbery pattern; and the deadwood pattern was shown only in Edmondson grade III and IV HCCs. CONCLUSIONS: The MFI technique is more effective in depicting the intratumoral vascular architecture. The vascular architecture pattern correlates with pathologic differentiation of HCC.  相似文献

PURPOSE: This study was performed to develop a standardized methodology for the sonographic assessment of clubfoot at birth and at the end of both conservative treatment and surgical correction. METHODS: Forty-two congenital clubfeet and 42 normal feet were examined sonographically in the position of spontaneous alignment and during passive manual correction. Scans along 4 planes provided information relevant to the assessment: sagittal posterior, sagittal anterior, coronal lateral, and transverse. RESULTS: Sagittal posterior sonograms demonstrated the progressive gain of dorsiflexion ability during the different steps of treatment for clubfoot. Sagittal anterior sonograms could not demonstrate the normal alignment of the navicular in clubfeet because of the bone's medial displacement. On transverse sonograms, the talar head and the medially displaced navicular may lie on the same plane, depending on the severity of the deformity. Coronal lateral sonograms provided for estimation of the relationships between the calcaneus and cuboid, which were described by the calcaneal-cuboid angle. CONCLUSIONS: Sonography is a promising technique for assessment and monitoring of clubfoot during treatment. The method described here yields accurate and reproducible information about the anatomy of the nonossified clubfoot, helping the orthopedic team decide on appropriate treatment steps.  相似文献
