Coarse Calcification

Objective: To investigate the diagnostic value of color Doppler ultrasonography in detecting calcifications in thyroid nodules for benign and malignant thyroid nodules. Methods: This study selects 108 patients with thyroid nodules who underwent color Doppler ultrasonography at designated hospitals from June 2013 to June 2018 as study subjects, retrospectively analyzes their general patient data, preoperative color Doppler ultrasound data and postoperative pathological diagnosis results, and discusses the diagnostic value of calcification rate, calcification type and calcification characteristics for benign and malignant thyroid nodules. Results: The results show that preoperative color Doppler ultrasonography found 112 thyroid nodules in 108 patients, including 72 benign nodules and 40 malignant nodules; pathological analysis confirmed 124 thyroid nodules, including 78 benign nodules and 46 malignant nodules; the diagnostic coincidence rate of color Doppler ultrasound is 90.32% (112/124), the misdiagnosis rate is 9.68% (12/124), the specificity is 86.94%, and the sensitivity is 81.27%; in these 112 thyroid nodules, 89 nodules were calcified accounting for 79.46%; in 72 benign nodules, 13 nodules were calcified accounting for 18.06%; in 40 malignant nodules, 17 were calcified accounting for 42.50%; the calcification of malignant nodules was significantly higher than that of benign nodules; in 72 benign nodules, 6 cases is coarse calcification accounting for 8.33%, 3 cases is cyclic calcification accounting for 4.16%, and cyclic and coarse calcification are only 23.46% sensitive to thyroid cancer; in 40 malignant nodules, 3 cases is coarse calcification accounting for 7.5%, and 2 cases is cyclic calcification accounting for 5.00%. Conclusions: According to the analysis, the calcification in thyroid nodules has relatively high sensitivity and specificity for the diagnosis of benign and malignant nodules and it can be used as a specific index for screening thyroid cancer.

Infertile Patients

Objective: To investigate the diagnostic value of color Doppler ultrasonography applied to infertile patients with chronic salpingitis and mycoplasma infection. Methods: 116 infertile patients with chronic salpingitis and mycoplasma infection were selected in this investigation. After these patients were admitted to hospital, they all underwent color Doppler ultrasound guided hysterosalpingogram and X-ray hysterosalpingography, in order to make definitive diagnoses, and the X-ray hysterosalpingography was considered as the gold standard. The diagnostic value and rates of adverse reaction between color Doppler ultrasound guided hysterosalpingogram and X-ray hysterosalpingography were evaluated. Results: A total of 116 patients with chronic salpingitis and mycoplasma infection received color Doppler ultrasound guided hysterosalpingogram and X-ray hysterosalpingography. Diagnostic coincidence rates were equal, and no statistical difference could be observed (P > 0.05), with respect to the tubal patency in double sides, tubal obstruction in double sides, tubal patency in single side, and tubal obstruction in single side. When concerning adverse reactions, the incidence rates of allergy and colporrhagia between two groups were statistically significantly different (P = 0.025 and P = 0.040, respectively). In addition, the total incidence rate of adverse reactions was also statistically significant different (P = 0.003). Conclusion: The color Doppler ultrasound aided hysterosalpingogram could make a diagnosis intuitively and clearly for patients with chronic salpingitis and mycoplasma infection, and can be used as the preferred method for diagnosing tubal infertility.

Primary Hepatic Carcinoma

Background: The efficacy of color Doppler ultrasound, multislice spiral CT combined with serum alpha-fetoprotein (AFP) and alpha-fetoprotein heterogeneity (AFP-L3) in the diagnosis of primary hepatic carcinoma was evaluated. Methods: Seventy-nine patients with primary hepatic carcinoma (PHC group) and 50 patients with benign liver lesions (benign control group) admitted in Yantaishan Hospital (Yantai, China) from January 2016 to December 2018 were selected. The liver was scanned by color Doppler ultrasound and multiple multislice spiral CT. The serum AFP and AFP-L3 levels were detected by electrochemiluminescence. The value of color Doppler ultrasound, multislice spiral CT combined with serum AFP and AFP-L3 in diagnosis of primary liver cancer was retrospectively analyzed. Results: The color Doppler flow imaging (CDFI) showed a high-speed and high-resistance spectrum. The serum AFP and AFP-L3 levels of patients with primary hepatic carcinoma were significantly higher than those of the benign control group were (U=138.000 and 155.500, P=0.000 and 0.000), P<0.01. The sensitivity, accuracy and negative predictive value of color Doppler ultrasound, multislice spiral CT combined with serum AFP and AFP-L3 examinations for diagnosis of primary hepatic carcinoma were 96.20, 90.70 and 93.18%, which was significantly improved compared with each single examination (X2=27.888, 17.511 and 16.202, P=0.000, 0.002 and 0.003), P<0.01. Conclusion: Color Doppler ultrasound, multislice spiral CT combined with AFP and AFP-L3 examination could significantly improve the diagnosis efficiency of primary hepatic carcinoma, which was beneficial to early clinical diagnosis and early treatment.
