Objective: The aim of the study was to identify the pathological characteristics of benign and malignant breast lesions among Saudi females using brightness mode (B-mode) and color Doppler ultrasound (US). Materials and Methods: This study was retrospectively carried out in a single center in the Radiology and Medical Imaging Department, King Fahad Medical City, Riyadh, Saudi Arabia. A convenient method of sampling was used to include all patients referred for different diagnosis during the period of January 2016 and December 2018. A sample size of 100 cases was selected with 50% of the cases being benign breast lesions, while the rest were malignant. The data collection instruments comprised data collection sheets, while a Philips US system with a 9 MHz linear probe was used to give the differential results. The results were considered significant when P < 0.05. The statistical diagnostic test was used to detect sensitivity, specificity, and accuracy of US in the differential diagnosis of breast lesions in Saudi females. Results: B-mode and color Doppler US findings of breast mass measurements, shape, echotexture, and the presence and absence of vascularity present a sensitivity, specificity, and accuracy of 97.09%, 80.65%, and 93.28% in the diagnosis of benign and malignant breast masses. Conclusion: In Saudi females with dense breasts, the risk of breast cancer development is increased. Moreover, B-mode in combination with color Doppler US was highly determined the results of differential diagnosis for any breast lesions.

Abstract Background Intra-articular bleeds in patients with inherited bleeding disorders lead to active synovitis which may progress to a chronic state over time. We explored the diagnostic value of color Doppler ultrasound in detecting synovitis in boys with bleeding disorders. Results Sixty boys with hemophilia and 3 boys with type 3 von Willebrand disease aged 5 to 18 years (median 12.3 years) were imaged by gray-scale and color Doppler ultrasound (US) in three centers (Beijing, China [n = 22], Guangzhou, China [n = 12] and Toronto, Canada [n = 29])) in this observational study. Images were independently reviewed by two radiologists blinded to clinical data using a subjective semi-quantitative scoring system and objective measurements of synovial thickness and vascularity. Inter-reader reliability for using subjective versus objective color Doppler US methods for assessing synovial vascularity was excellent for the subjective method and moderate/lower range of substantial for the objective method. Agreement between degree of vascularity on color Doppler and extent of synovial hypertrophy on gray-scale US was overall poor for Canada data and moderate for China data. Correlations between degree of vascularity on color Doppler and synovial hypertrophy on gray-scale US, and clinical constructs (total and itemized HJHS scores and total Pettersson X-ray scores) for assessment of blood-induced arthropathy were all poor. Conclusion Color Doppler US is a valuable scoring method for evaluating reactive synovitis in joints of subjects with inherited bleeding disorders and holds potential for assessing post-bleed reactive synovitis once further information on its association with timing of the joint bleed becomes available in the literature.

Objective: To study the value of color Doppler ultrasound and ultrasound contrast in differential diagnosis of ovarian tumors. Methods: Ninety-six patients with ovarian tumors who were treated in our hospital from May 2017 to July 2018 and confirmed by pathological examination were selected as the research subjects. All patients were examined by color Doppler ultrasound and ultrasound contrast. The sensitivity, specificity and accuracy of the two methods were compared, and the parameters of ultrasound contrast in the diagnosis of benign and malignant tumors were observed and compared. Results: The sensitivity, specificity and accuracy of ultrasound contrast in the diagnosis of ovarian tumors were higher than those of color Doppler ultrasound (P<0.05). There were significant differences in the time of initiation enhancement, time to peak and perfusion intensity in the diagnosis of benign and malignant lesions by ultrasound contrast (P<0.05). Conclusion: In the differential diagnosis of ovarian tumors, ultrasound contrast has more advantages than color Doppler ultrasound in displaying the blood perfusion information of tumors. It has high diagnostic accuracy and clinical application value. doi: https://doi.org/10.12669/pjms.36.2.847 How to cite this:Zhang H, Wang J, Guo R.

The incidence of breast cancer ranks first among female malignant tumor. With the increase of the sensitivity of color Doppler ultrasound blood flow, the blood flow distribution in and around the tumor can be clearly displayed, and the analysis of hemodynamic parameters is provided, which provides convenience for the study of tumor blood flow characteristics. Studies have shown that tumor cells can secrete a substance called angiogenesis factor, which makes the tumor site form a rich vascular network to promote tumor growth and metastasis. The tumor has many new blood vessels, abnormal structure, thin wall, lack of muscle layer, and is prone to form arteriovenous rash. These characteristics provide a pathological basis for color Doppler flow imaging (CDFI) for the diagnosis of breast cancer. This article discusses the role of two-dimensional sonographic features in the differential diagnosis of benign and malignant breast masses, CDFI was used to study the blood flow distribution and hemodynamic characteristics in benign and malignant breast masses; explore the value of blood flow characteristics and blood flow parameters in the differential diagnosis of breast masses. The experimental results show that the detection rate of blood flow signals and the classification of blood flow signals in the malignant group are higher than those in the benign group, mainly level II and III blood flow, and the irregular branched blood flow is more common, especially when the tumor appears penetrating blood flow supports the diagnosis of malignancy. PSV, RI and PI have a certain differential meaning in the diagnosis of benign and malignant breast masses. PSV, RI and PI of malignant masses are higher than benign masses. For tumors without obvious necrosis, the larger the tumor diameter, the richer the blood flow and the higher the blood flow grade is. The malignant tumors have more blood flow than the benign ones.

PURPOSE: To evaluate the diagnostic value of shear wave velocity (SWV) ratio for the differential diagnosis of benign and malignant breast lesions. MATERIAL AND METHODS: Our retrospective study included 151 breast lesions that were diagnosed by biopsy and surgical pathology. All of the breast lesions were detected by conventional ultrasound and Virtual Touch tissue quantification (VTQ) and mammography. The sonographic characteristics of the breast lesion, such as the internal echo, shape, margin, color flow, and calcification so on, were also observed. The SWV in lesions and surrounding parenchyma were measured and the SWV ratio between the lesion and surrounding parenchyma was calculated. Pathological results were used as a diagnosis standard to compare the value of SWV ratio, VTQ, and mammography in the diagnosis of benign and malignant breast lesions. RESULTS: The 151 breast lesions included 96 benign lesions and 55 malignant lesions. The cutoff value of VTQ in the diagnosis of benign and malignant breast lesions was 5.01 m/s, of SWV ratio was 2.43, and mammography was BI-RADS 4B. The sensitivity, specificity, accuracy and the area under the ROC curve (AUC) of the SWV ratio were 78.2%, 86.5%, 83.4%, and 0.83 respectively. While of SWV ratio with mammography was 86.4%, 89.4%, 88.3% and 0.87, respectively. The sensitivity, specificity, accuracy, and AUC of SWV ratio and SWV ratio with mammography were statistically higher than those of mammography, no statistically higher than VTQ and VTQ with mammography. CONCLUSION: The SWV ratio can improve the sensitivity without sacrificing diagnostic specificity in the process of breast cancer diagnostic, provide a better diagnostic performance, and avoid unnecessary biopsy or surgery.
