INTRODUCTION: Breast cancer is the most common cancer in women worldwide. It is responsible for about 23% of cancer in females in both developed and developing countries. This study aimed to compare the diagnostic performance of contrast-enhanced mammography (CEM) and contrast-enhanced magnetic resonance imaging (CEMRI) in preoperative evaluations of breast lesions. METHODS: We searched for published literature in the English language in MEDLINE via PubMed and EMBASETM via Ovid, The Cochrane Library, and Trip database. For literature published in other languages, we searched national databases (Magiran and SID), KoreaMed, and LILACS. Metadisc1.4 software was used for statistical analysis RESULTS: A total of 1225 patients were included. The pooled sensitivity of CEM and CEMRI was 0.946 (95% CI, 0.931–0.958) and 0.935 (95% CI, 0.920–0.949), respectively. The pooled specificity of CEM and CEMRI was 0.783 (95% CI, 0.758–0.807) and 0.715 (95% CI, 0.688–0.741), respectively. The sensitivity of CEM was the most in the United States (97%) and the specificity of CEM was the most in Brazil (88%). MRI sensitivity was the most in USA and Egypt (99%) and China had the most MRI specificity (81%) in diagnosis of breast lesions. CONCLUSION: Contrast-enhanced mammography, a combination of high energy image and low energy image, can well display breast lesions and has the diagnostic efficacy equivalent to MRI. Importantly, CEM imaging shows higher specificity, positive predictive value, and diagnostic conformance rate than MRI. Despite some drawbacks such as higher irradiation and iodine usage, CEM has such advantages as convenient and fast examination, strong applicability, and low costs; thus, it can be popularized as a useful tool in breast disease.

Background: Extraction by conventional methods such as Soxhlet requires a long time and the possibility of damage to heat-sensitive compounds. Objectives: In this study, modern ultrasound methods used to perform and investigate the antibacterial properties of plant extracts were compared. Methods: The extracts of Mentha piperita, Rosmarinus officinalis, and Withania somnifera were prepared by an ultrasound device. Ten Escherichia coli strains were isolated from poultry stool samples. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) plant extracts against E. coli were determined using the microdilution method. Results: The results showed that the lowest inhibitory concentrations of rosemary, peppermint, and wind cheese extracts prepared by ultrasound were equal to 3.1 mg/mL, while the highest inhibitory concentrations of these extracts were equal to 25, 25, and 50 mg/mL, respectively. The lowest lethal concentrations of rosemary, peppermint, and wind cheese extracts were 6.25 mg/mL, while the highest inhibitory concentrations of these extracts were 25, 25, and 50 mg/mL, respectively. The lowest bactericidal concentrations of rosemary, peppermint, and wind cheese extracts prepared by ultrasonic waves were equal to 6.25 mg/mL, while the highest lethal concentrations of these extracts were equal to 50, 25, and 100 mg/mL, respectively. Conclusions: According to the findings of the study, it can be concluded that the use of ultrasonic waves is a fast, effective, and economical method for extracting plant components. In addition, the methanolic extract of peppermint has the most inhibitory and lethal properties.
