Methods Sonographical appearance and pathological characteristics of 222 patients from 2008 to 2009 with apophysis lesions of the gallbladder which were confirmed by pathologic diagnosis and operation were reviewed retrospectively. Results One hundred and seventy-five (78.8%) of the patients had gallbladder cholesterol lipoidosis and 138 (62.2%) of them had gallbladder cholesterol polyps;3 patients (1.4%) had gallbladder inflammatory polyp;14 patients (6.3%) had gallbladder adenomatoid polyps and 7 of them were accompanied with dyplasis and atypical hyperplasia; 1 (0.5%) patients (0.5%) had cholecystic adenomyosis. Tenty-nine patients (13.1%) had cholecystitis only. Conclusion Ultrasonography is quilt sensitive to this disease and can disply the size, number, echo, shape of the lesions and can show that if complicate with cholecystolithiasis.Ultrasonography is also accomplished in follow-up and can be one of the most dependable examination methods.
目的 探討彩色多普勒超聲診斷膀胱破裂的診斷價值,以提高膀胱破裂的超聲診斷水平。 方法 回顧性分析2002年1月－2011年9月術前行彩色超聲檢查診斷膀胱破裂并經手術證實的5例患者資料，下腹加壓檢查和經導尿管注水試驗檢查作為超聲判斷有無膀胱破裂的重要檢查方法。 結果 5例均為腹膜外型膀胱破裂,彩色多普勒血流顯像明確診斷4例，漏診1例，超聲檢查是診斷膀胱破裂的有效方法。 結論 彩色多普勒超聲可以作為膀胱破裂的首選檢查技術。Objective To investigate the value of color doppler flow image (CDFI) in diagnosing bladder rupture, in order to promote the ultrasound diagnosis for the disease. Methods We retrospectively analyzed the medical data of 5 patients with bladder rupture diagnosed by CDFI before operation and confirmed by surgery. Pressing the lower abdomen and injecting water through catheter were the main examination methods for CDFI in diagnosing bladder rupture. Results All the 5 cases were bladder rupture of extraperitoneal type. Four were diagnosed with CDFI, and 1 was misdiagnosed. The ultrasonic examination was an effective technology in diagnosing bladder rupture. Conclusion CDFI may be regarded as the first diagnostic technology for bladder rupture.
ObjectiveTo explore the diagnostic value of sonography in thyroid imaging reporting and data system (TI-RADS) for thyroid nodules. MethodsA total of 292 patients (423 nodules) underwent thyroid examination with high frequency ultrasound. The results were retrospectively compared with histopathological diagnosis and TI-RADS lexicon. ResultsThe category 1-5 of 423 thyroid nodules were evaluated by using TI-RADS, and it’s frequency of being malignancy rate was 0(0/129), 6.3%(11/176), 33.3%(10/30), 86.8%(46/53), and 100% (35/35), respectively. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for benign thyroid nodule of ultrasound in TI-RADS was 96.3%（309/321）, 83.3%（85/102）, 93.1%（394/423）, 94.8%（309/326）, and 87.6%（85/97）, respectively. Positive likelihood ratio, negative likelihood ratio, and Youden’ index was 5.77, 0.04, and 79.6%, respectively. The benign and malignancy nodule of TI-RADS category were statistically difference in shape, margin, echogenicity, echotexture, composition, and calcification inside the nodule (Plt;0.001). ConclusionsTI-RADS lexicon has an important guiding value for clinical diagnosis and treatment in ultrasound examination of thyroid nodule.
ObjectiveTo evaluate the value of preoperative risk assessment of papillary thyroid carcinoma with ultrasound for clinic diagnosis and treatment.MethodsThe data of 400 patients with papillary thyroid carcinoma received operative treatment in 2017 were retrospectively analyzed. Recorded and analyzed the ultrasonic risk assessment and postoperative grading of clinic risk assessment, to evaluate coherence and correlation between them.ResultsThere were 400 lesions with an average size of (12.8±8.5) mm. Among 400 lesions, diameter of 214 lesions less than 10 mm, diameter of 178 lesions were between 10 mm and 40 mm, and diameter of 8 lesions were larger than 40 mm. A total of 242 cases had lymph node metastasis and 309 cases had capsule invasion. Clinical and ultrasoud risk assessment was performed on 400 lesions. There were 224 lesions with low risk of clinical risk stratification vs. 111 lesions with low ultrasonic risk, 148 lesions with intermediate risk of clinical risk stratification vs. 270 lesions with intermediate ultrasonic risk, and 28 lesions with high risk of clinical risk stratification vs. 19 lesions with high ultrasonic risk. The consistency of postoperative recurrence risk stratification and preoperative ultrasound recurrence risk stratification was moderate (κ=0.414, P<0.01). In addition, the consistency between ultrasound examination and clinical lymph node metastasis was poor (κ=0.291, P<0.05), and the consistency of invasion of the capsule was moderate (κ=0.402, P<0.05).ConclusionPre- operative evaluation of recurrence risk grading before thyroid ultrasound, focusing on individualized preoperative assessment, the assessment is more detailed and detailed, and is helpful for follow-up treatment and early screening for recurrence risk.
【摘要】 目的 探討胃腸道間質瘤(GIST)彩色多普勒超聲表現及其在診斷中的應用價值。 方法 回顧性分析2008年1月-2010年7月75例經病理證實的GIST的彩色多普勒超聲聲像圖表現，將其與手術病理結果進行對比分析。 結果 GIST患者中男性高危險度腫瘤的比例較女性高（χ2=7.210，Plt;0.01）。腫瘤的大小、內部回聲與其病理危險度高低有關:危險度低者、腫瘤最大徑lt;5 cm，內部回聲較均勻；危險度高者，腫瘤最大徑≥5 cm，內部回聲不均勻。腫瘤的彩色血流分布與其危險度高低無明顯相關。常規的超聲檢查對腫瘤檢出率較高，在胃及直腸的GIST診斷準確率高于其他部位的GIST。 結論 彩色多普勒超聲檢查有助于GIST的定位及分化程度的判斷，可作為首選檢查方法。【Abstract】 Objective To investigate the value of ultrasonography in the diagnosis of gastrointestinal stromal tumors (GIST). Methods The color sonographic performances obtained in 75 patients with pathologically proved GIST from January 2008 to July 2010 were retrospectively analyzed. The sonographic findings were compared with pathological results. Results The proportion of high-risk cancer in male patients with GIST was higher than that in women (χ2=7.210, Plt;0.01). The tumor size and internal echo level were related to its pathologic risk: in low-risk GIST, maximum tumor diameter was lt;5 cm, and internal echo was more homogeneous; in high-risk GIST, maximum tumor diameter was ≥ 5 cm and internal echo was heterogeneous. There was no statistical difference between tumor blood flow distribution and GIST risk. Routine sonography examination had a higher rate of cancer detection and had a higher accuracy in the diagnosis of GIST in the stomach and rectum than those in the other parts. Conclusion Sonography helps to locate and diagnose malignant GIST, which is a common and preferred screening method.

Methods From January 2006 to December 2009, 7 532 healthy women underwent breast sonography. The results of sonography in the individuals with different ages were statistically analyzed. Results Breast lesions were found in 2 861 cases (37.98%) and the other 4 671 were healthy. Among all of the individuals, 1 904 cases (25.28%) had cystic lesions, 944 (12.53%) had solid lesions and 13 (0.17%) had mixed lesions. There were 692 cases of accessory mammary tissue. Unilateral cystic nodules and solid nodules were more common than bilateral ones, whereas mixed nodules were usually sunilaterally. Cystic nodules were more common than solid nodules. Most common onset of breast lesions is in the individuals with the age of 20-30 and 31-40 years. Conclusion High-frequency sonography, as an examination for normal clinical breast screening provides more accurate diagnosis and early detection of breast lesions, which can provide scientific evidence for early detection, diagnosis and treatment for breast cancer.
