Application value of 3T 1H-magnetic resonance spectroscopy in diagnosing breast tumors.

ConclusionThe combined use of (1)H-MRS and DCE-MRI found to have improved diagnostic performance in the assessment of equivocal breast lesions. (1)H-MRS can be used as a useful adjunct during lesion characterization in clinical routine in cases classified as BI-RADS 3 and 4. PMID: 23436823 [PubMed - as supplied by publisher]

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.

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,...

ConclusionTOL methodology allowed effective training of both groups of readers. The iterative nature of individual training ensured production of user-friendly materials including frequently-asked-questions sheets. It allowed for each person to feel that their views were fully listened to and incorporated into the training package, allowing for training materials with high face validity.

Conclusion: The texture analysis for breast DCE-MRI proposed in this study demonstrated potential utility in HER2 2+ status discrimination. Background Human epidermal growth factor receptor 2 (HER2) is an orphan tyrosine kinase receptor. It is reported that HER2 is overexpressed in 15–20% of breast cancers. Overexpression of HER2 in breast cancer correlates with shortened disease-free survival. Compared with HER2-negative patients, patients with HER2-positive breast cancers have a poor prognosis, a high probability of lymph node metastasis and a high risk of recurrence (1–3). However, previous studies h...

Authors: D'Angelo A, Rinaldi P, Belli P, D'Amico R, Carlino G, Grippo C, Giuliani M, Orlandi A, Infante A, Manfredi R Abstract OBJECTIVE: We investigated the accuracy of Automated Breast Volume Scanner (ABVS) compared to handheld ultrasound (HHUS) for monitoring tumor response to neoadjuvant treatment (NAT) in breast cancer (BC). PATIENTS AND METHODS: All the patients submitted to biopsy in our Institution, from January 2017 to May 2017, proven invasive BC and eligible for NAT, were enrolled in this prospective study. The participants underwent ABVS, HHUS, dynamic contrast-enhanced Magnetic Resonance Imaging (D...

Publication date: November 2018Source: Academic Radiology, Volume 25, Issue 11Author(s): Rossella Rella, Paolo Belli, Michela Giuliani, Enida Bufi, Giorgio Carlino, Pierluigi Rinaldi, Riccardo ManfrediAutomated breast ultrasonography (ABUS) is a new imaging technology for automatic breast scanning through ultrasound. It was first developed to overcome the limitation of operator dependency and lack of standardization and reproducibility of handheld ultrasound. ABUS provides a three-dimensional representation of breast tissue and allows images reformatting in three planes, and the generated coronal plane has been suggested t...

Authors: Coutinho I, Marques M, Almeida R, Custódio S, Simões Silva T, Águas F Abstract Orbital metastasis is a rare event, and metastatic disease affecting the extraocular muscles is an even less frequent complication of solid tumors. Herein, we report an unusual case of ptosis as the initial presentation of an invasive breast cancer. A 68-year-old woman presented with III and VI partial nerve paresis, secondary to a compressive retrobulbar mass. Magnetic resonance imaging revealed an infiltrative lesion involving the extraocular muscles. Tissue biopsy yielded a result compatible with metastas...
