When it comes to the microbiome, people usually think of the gut, but there is also the breast microbiome, and its role in the health and risk of breast cancer is not fully understood. A microbiome is a collection of microorganisms that live in a specific environment in the body. Diet can affect the breast microbiome, which shows that like the gut microbiome, breast microbiomes can respond to diet. New research now shows that diet, including fish oil supplements, can alter not only the breast microbiome but also its cancerous tumors.

Objective We compared the diagnostic values of mammography and magnetic resonance imaging (MRI) for evaluating breast masses. Methods We retrospectively analyzed mammography, MRI, and histopathological data for 377 patients with breast masses on mammography, including 73 benign and 304 malignant masses. Results The sensitivities and negative predictive values (NPVs) were significantly higher for MRI compared with mammography for detecting breast cancer (98.4% vs. 89.8% and 87.8% vs. 46.6%, respectively). The specificity and positive predictive values (PPV) were similar for both techniques. Compared with mammography alone, mammography plus MRI improved the specificity (67.1% vs. 37.0%) and PPV (91.8% vs. 85.6%), but there was no significant difference in sensitivity or NPV. Compared with MRI alone, the combination significantly improved the specificity (67.1% vs. 49.3%), but the sensitivity (88.5% vs. 98.4%) and NPV (58.3% vs. 87.8%) were reduced, and the PPV was similar in both groups. There was no significant difference between mammography and MRI in terms of sensitivity or specificity among 81 patients with breast masses with calcification. Conclusion Breast MRI improved the sensitivity and NPV for breast cancer detection. Combining MRI and mammography improved the specificity and PPV, but MRI offered no advantage in patients with breast masses with calcification.

: This review article aims to address the main features of breast cancer. Thus, the general aspects of this disease have been shown since the first evidence of breast cancer in the world until the numbers today. In this way, there are some ways to prevent breast cancer, such as the woman's lifestyle (healthy eating habits and physical activities) that helps to reduce the incidence of this anomaly. The first noticeable symptom of this anomaly is typically a lump that feels different from the rest of the breast tissue. More than 80% of breast cancer are discovered when the woman feels a lump being present and about 90% of the cases, the cancer is noticed by the woman herself. Currently, the most used method for the detection of cancer and other injuries is the Magnetic Resonance Imaging (MRI) technique. This technique has been shown to be very effective, however, for a better visualization of the images, contrast agents (CAs) are used, which are paramagnetic compounds capable of increasing the relaxation of the hydrogen atoms of the water molecules present in the body tissues. The most used CAs are Gd3+ complexes, although they are very efficient, they are toxic to the organism. Thus, new contrast agents have been studied to replace Gd3+ complexes, we can mention iron oxides as a promising substitute.

Magnetic resonance imaging (MRI), a useful technique of studying soft tissues of the body, can be very effective in assessing the integrity of tendons. Usually a patient with a complete tear of the posterior tibial tendon has characteristic physical findings. In the patient presented, MRI demonstrated a complete disruption of the posterior tibial tendon, despite the absence of the commonly associated clinical findings. In view of the difficulties encountered with attempted tenography of the completely torn posterior tibial tendon, MRI provides a sensitive alternative diagnostic technique.

Magnetic Resonance Imaging Mri

A wide variety of benign and malignant breast processes may generate hyperintense signal at T2-weighted magnetic resonance imaging (MRI). MRI has been traditionally used in the pre-treatment planning of breast cancer, in assessing treatment response and detecting recurrence. In this comprehensive review, we describe and illustrate the MRI features of a few common and uncommon T2 hyperintense breast lesions, with an emphasis on MRI features that help to characterize lesions based on morphological features, specific appearances on T1-and T2-weighted imaging, and enhancement characteristics on the dynamic post-contrast phase that are either diagnostic or aid in narrowing the differential diagnosis.
