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.

The purpose of this study was to investigate the diagnostic value of color Doppler ultrasound combined with superb microvascular imaging (SMI) in the detection of small renal tumors less than 3 cm treated with Jinkui Shenqi pills. 50 cases were randomly selected from the patients with angioleiomyoma (a kind of small renal tumor) less than 3 cm confirmed by pathological examination and treated in our hospital from January 2018 to January 2020. All patients were treated with Jinkui Shenqi pills. All patients were first detected by color Doppler ultrasound and then by SMI. The results of color Doppler ultrasound were used as the control group, while those of color Doppler ultrasound combined with SMI were used as the experimental group. After that, the specificity, sensitivity, positive and negative detection results, and detection accuracy were compared between the two groups. The specificity and sensitivity in the experimental group were significantly higher than those in the control group, with statistical significance ( P < 0.05 ). The cases of positive and negative detection results in the experimental group were significantly higher than those in the control group, with statistical significance ( P < 0.05 ). The detection accuracy in the experimental group was significantly higher than that in the control group, with statistical significance ( P < 0.05 ). The specificity, sensitivity, positive and negative detection results, and detection accuracy of color Doppler ultrasound combined with SMI in the detection of small renal tumors less than 3 cm treated with Jinkui Shenqi pills were all significantly higher than those of color Doppler ultrasound; therefore, the application of color Doppler ultrasound combined with SMI for the diagnosis of small renal tumors is of high value.
