Added value of contrast-enhanced spectral mammography in symptomatic patients with dense breasts

The Egyptian Journal of Radiology and Nuclear Medicine, 2021
Background Breast cancer is the most common malignancy in females around the world representing 25.1% of all cancers. The high prevalence and need for early treatment of breast malignancy highlight the importance of early and accurate diagnosis. In order

Multi-detector CT chest: can it omit the further need for contrast enhnaced spectral mammography in breast cancer patients candidate for CT staging?

The Egyptian Journal of Radiology and Nuclear Medicine, 2022
Background During multi-detector computed tomography (MDCT) of the chest, incidental breast lesions (IBLs) are occasionally encountered. Mammography remains the gold standard for the early detection of breast cancer.

Design of an In Vivo‐Like Phantom for Quantitative Body CEST MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To design and validate a reproducible in vivo‐like fat‐containing CEST phantom that enables robust quantitative CEST MRI for body applications by providing physiologically realistic relaxation properties, relevant endogenous CEST contrasts (amide, guanidino, rNOE, and semi‐solid MT), and a controlled fat component.

Proteomic Analysis of Mixed Cell Membrane Extracts From Triple‐Negative Breast Cancer Cell Lines Revealed Broad Metabolic Reprogramming Associated With Tumor Progression

PROTEOMICS, EarlyView.
ABSTRACT Triple‐negative breast cancer (TNBC) represents the most aggressive subtype with limited therapeutic options and the poorest clinical outcomes. Using high‐resolution nUPLC‐QTOF‐MS/MS, we performed comprehensive proteomic profiling of TNBC cell lines representing disease progression stages: HCC‐1937 (stage IIB), HCC‐1599 (stage IIIA), and MDA ...

Spindle Cell Lesions of the Breast: A 12‐Year Experience

ANZ Journal of Surgery, EarlyView.
This 12‐year, single‐centre study examined 30 core‐biopsy‐diagnosed breast spindle cell lesions (BrSCL), classified as atypical (ASCL, n = 10) or bland (BSCL, n = 20). Following excision, 80% of ASCLs proved malignant, comprising sarcoma, malignant phyllodes tumour and metaplastic carcinoma.
