CONCLUSION: 15O-H2O PET/CT is safe and effective for the early detection and quantitative analysis of subclinical post-radiotherapy changes in heart perfusion in breast cancer patients. The LV segments supplied by the LAD are the main site of MBF changes. A minimum radiation dose deposited in the LAD may be a predictor of radiation-induced heart toxicity. Advances in knowledge: This is the first time that 15O-H2O PET/CT has been used to assess MBF after radiotherapy and the first granular description of the distribution of blood flow changes after breast cancer radiotherapy.

This article reviews the impact of MR imaging in different settings on medical oncology decision-making in patients with breast cancer.
Breast MR imaging has been shown to identify unsuspected sites of cancer in the ipsilateral breast in 16% of women with newly diagnosed breast cancer. Breast MR imaging identifies occult cancer in the contralateral breast in 3% to 5% of women. Early evidence suggests that the added value of MR imaging for staging may be attenuated in women who also undergo tomosynthesis, particularly those with nondense breasts. Breast MR imaging is complementary to ultrasound imaging in evaluating regional nodal basins. Ongoing prospective randomized clinical trials should clarify the impact of preoperative breast MR imaging on clinical outcomes.

ConclusionsMagnetic seeds are a feasible and safe method of breast lesion localization. They can be accurately placed, demonstrate no migration in this feasibility study and are detectable in all sizes and depths of breast tissue. Now that safety and feasibility have been demonstrated, further clinical studies are required to evaluate the seed ’s effectiveness in wide local excision surgery.
CONCLUSIONS: IC has been stated as a good technique for intraoperative cancer involvement SN with high sensitivity and NPV compared to the OSNA assay. It allows keeping the whole node tissue and thus the possibility of improved histopathological evaluation, which can be useful for adjuvant, and offers the advantage of being less time consuming. Cost analysis shows a higher cost for OSNA, which may exceed the benefit of sorting out false negatives from IC. PMID: 29455041 [PubMed - as supplied by publisher]
Abstract Ultrasound assisted the copper-catalyzed cross-coupling reaction to synthesis 1-(10-bromoanthracene-9-yl)-1H-imidazole-4,5-dicarboxylic acid (A-Im). The obtained product was employed to modify graphene oxide (GO) surface to produce GO-A-Im. The resulted hybrid was characterized with Scanning Electron Microscope (SEM/EDS); X-ray Diffraction spectroscopy (XRD); X-ray photoelectron spectroscopy (XPS); Fluorescence spectroscopy; Fourier transformed infrared spectroscopy (FT-IR), Brunauer-Emmett-Teller (BET), and UV-Vis absorption spectroscopy. The synthesized (A-Im) moiety that was used for functionalization ...
ConclusionMBI seems to be a useful imaging modality with a high predictive value in revealing ipsilateral and bilateral disease not visualized by mammography and ultrasound. It may play an important role in delineating the extent of the index lesion during preoperative planning. Incorporation of MBI in the clinical work-up as an adjunct modality to mammography and ultrasound may lead to better selection of patients who could benefit from BCS.
AbstractObjectivesTo determine the effect of computer-aided-detection (CAD) software for automated breast ultrasound (ABUS) on reading time (RT) and performance in screening for breast cancer.Material and methodsUnilateral ABUS examinations of 120 women with dense breasts were randomly selected from a multi-institutional archive of cases including 30 malignant (20/30 mammography-occult), 30 benign, and 60 normal cases with histopathological verification or ≥ 2 years of negative follow-up. Eight radiologists read once with (CAD-ABUS) and once without CAD (ABUS) with> 8 weeks between reading sessions. Readers provided ...
This study investigated the feasibility of using strain elastography (SE) and real time shear wave elastography (RT-SWE) to evaluate early tumor response to cytotoxic chemotherapy in a murine xenograft breast cancer tumor model. METHODS: MCF-7 breast cancer-bearing nude mice were treated with either cisplatin 2 mg/kg plus paclitaxel 10 mg/kg (treatment group) or sterile saline (control group) once daily for 5 days. The tumor elasticity was measured by SE or RT-SWE before and after therapy. Tumor cell density was assessed by hematoxylin and eosin staining, and the ratio of collagen fibers in the tumor was evaluated by ...
