MRIs of dense breasts find more cancer but also false alarms

Giving women with very dense breasts an MRI scan in addition to a mammogram led to fewer missed cancers but also to a lot of false alarms, a large new study suggests.

CONCLUSION: Imaging tools used to evaluate breast cancer can help determine whether distant metastasis has occurred and in rare cases can help discover other primary cancers. The patient in this case study was 1 of the few patients with an incidental finding of a second nonmetastatic primary malignancy in the lung detected using PET-CT. The risks associated with advanced imaging include exposing patients to additional tests and potentially invasive procedures based on the results. However, in some instances, imaging results can alter the treatment plan and increase survival rates. Further empirical research and case studie...

AbstractBackgroundThe density of tumor-infiltrating lymphocytes (TIL) is a predictive factor for response to neoadjuvant systemic therapy (NAST) in breast cancer. High TIL density correlates with higher complete pathologic remission (pCR) in triple negative and HER2 positive breast cancer. Additionally, not only TIL density but also subsets of immune cells in tumor stroma seem to play an important role in cancer and immune cell interaction and response to chemotherapy. Our aim is to determine TIL density and expression of CD 20, CD3, CD8, PD-L1, FOXP3 and PGM1 on core biopsy specimen and find a correlation with pCR.Trial d...

ConclusionConventional BC-imaging modalities have both advantages and limitations. When utilized in combination, they are often complementary. For example, a limitation of mammography is low sensitivity in dense breasts. The addition of DBT lessens this limitation by providing three-dimensional (3D) images of the breast that minimizes the effect of overlying breast tissue. Additionally, US added to mammography in dense breasts increases screening sensitivity and has the advantages of accessibility and lack of ionizing radiation. MRI is currently the most sensitive method used for detecting BC. When MRI is not suitable for ...

ConclusionsA novel system using supine MRI images co-registered with intraoperative optical scanning and tracking enabled tumors to be resected with a trend toward a lower positive margin rate compared with wire-localized partial mastectomy. Margin positivity was more likely when imaging underestimated pathologic tumor size.

This article presents a novel and completely automated algorithm for the detection of microcalcification clusters in a mammogram. A multiscale 2D non-linear energy operator is proposed for enhancing the contrast between the microcalcifications and the background. Several texture, shape, intensity, and histogram of oriented gradients (HOG) –based features are used to distinguish microcalcifications from other brighter mammogram regions. A new majority class data reduction technique based on data distribution is proposed to counter data imbalance problem. The algorithm is able to achieve 100% sensitivity with 2.59, 1.7...

AbstractPurposeTo develop a multiparametric [18F]FDG positron emission tomography/magnetic resonance imaging (PET/MRI) model for breast cancer diagnosis incorporating imaging biomarkers of breast tumors and contralateral healthy breast tissue.MethodsIn this prospective study and retrospective data analysis, 141 patients (mean 57  years) with an imaging abnormality detected on mammography and/or ultrasound (BI-RADS 4/5) underwent combined multiparametric [18F]FDG PET/MRI with PET/computed tomography and multiparametric MRI of the breast at 3  T. Images were evaluated and the following were recorded: for the tumor,...
