Calcifications and tungsten deposits after breast-conserving surgery and intraoperative radiotherapy for breast cancer.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE To describe the presence of atypical calcifications on post-operative mammography after breast-conserving surgery (BCS) and intraoperative radiotherapy (IORT). METHODS We retrospectively include all patients followed after BCS and IORT for breast cancer (n=271). All follow-up mammograms at

Tungsten targets the tumor microenvironment to enhance breast cancer metastasis.

Numai utilizatorii înregistrați pot traduce articole

The number of individuals exposed to high levels of tungsten is increasing, yet there is limited knowledge of the potential human health risks. Recently, a cohort of breast cancer patients was left with tungsten in their breasts following testing of a tungsten-based shield during intraoperative

Dosimetric Feasibility of Using Tungsten-Based Functional Paper for Flexible Chest Wall Protectors in Intraoperative Electron Radiotherapy for Breast Cancer.

Numai utilizatorii înregistrați pot traduce articole

Intraoperative electron radiotherapy (IOERT), which is an accelerated partial breast irradiation method, has been used for early-stage breast cancer treatment. In IOERT, a protective disk is inserted behind the target volume to minimize the dose received by normal tissues. However, to use such a

Highly efficient ablation of metastatic breast cancer using ammonium-tungsten-bronze nanocube as a novel 1064 nm-laser-driven photothermal agent.

Numai utilizatorii înregistrați pot traduce articole

Photothermal ablation (PTA) therapy has been viewed as an invasive option for cancer therapy with minimal deconstruction of healthy tissues. In this study, a potent candidate of (NH4)xWO3 nanocube was developed for PTA treatment of metastatic breast cancer in the second near-infrared (NIR) window.

A stimulated liquid-gas phase transition nanoprobe dedicated to enhance the microwave thermoacoustic imaging contrast of breast tumors

Numai utilizatorii înregistrați pot traduce articole

Microwave-induced thermoacoustic imaging (MTAI), combining the advantages of the high contrast of microwave imaging and the high resolution of ultrasonic imaging, is a potential candidate for breast tumor detection. MTAI probes have been used to extend thermoacoustic imaging to molecular imaging.

Tumor ablation using novel photothermal NaxWO3 nanoparticles against breast cancer osteolytic bone metastasis.

SU-E-T-399: Dosimetric and Geometric Evaluation of a Novel Stereotactic Radiotherapy Device for Breast Cancer: The GammaPod.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE A dedicated stereotactic irradiation device, the GammaPodTM, was developed to treat early stage breast cancer. This study presents the first description of the dosimetric and geometric characteristics from the prototype unit. METHODS The GammaPod stereotactic radiotherapy device is an

Dosimetric and geometric evaluation of a novel stereotactic radiotherapy device for breast cancer: the GammaPod™.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE A dedicated stereotactic gamma irradiation device, the GammaPod™ from Xcision Medical Systems, was developed specifically to treat small breast cancers. This study presents the first evaluation of dosimetric and geometric characteristics from the initial prototype installed at University

The novel technique of delivering targeted intraoperative radiotherapy (Targit) for early breast cancer.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE We believe that conservative treatment of early breast cancer may not require radiotherapy that encompasses the whole breast in all patients. We have developed a novel therapeutic approach that allows targeted intraoperative radiotherapy (Targit) to be safely and accurately delivered in a

Targeted photothermal therapy of mice and rabbits realized by macrophage-loaded tungsten carbide.

Numai utilizatorii înregistrați pot traduce articole

Although great advances have been made in photothermal therapy, the efforts hitherto have mainly achieved antitumor effects in mice with a subcutaneous tumor model, which is less clinically relevant. Therefore, it is very urgent to make further progress in investigating the possibility of larger

Availability of rhenium-188 from the alumina-based tungsten-188/rhenium-188 generator for preparation of rhenium-188-labeled radiopharmaceuticals for cancer treatment.

Numai utilizatorii înregistrați pot traduce articole

Rhenium-188 (beta- = 2.2 MeV; gamma = 155 keV; T1/2 16.9 hours) is an attractive therapeutic radioisotope which is produced from decay of the reactor-produced tungsten-188 parent (T1/2 69 days) and thus conveniently obtained on demand by elution from the alumina-based tungsten-188 /rhenium-188

Mean glandular dose estimation using MCNPX for a digital breast tomosynthesis system with tungsten/aluminum and tungsten/aluminum+silver x-ray anode-filter combinations.

Numai utilizatorii înregistrați pot traduce articole

Breast cancer screening with x-ray mammography, using one or two projection images of the breast, is an indispensible tool in the early detection of breast cancer in women. Digital breast tomosynthesis (DBT) is a 3D imaging technique that promises higher sensitivity and specificity in breast cancer

Screen-film mammographic technique for breast cancer screening.

Numai utilizatorii înregistrați pot traduce articole

The values of dose and signal-to-noise ratio (SNR) for many techniques and breast thicknesses were computed and compared with a reference technique and breast thickness to provide a valid basis upon which to select a screening technique for screen-film mammography. The reference consisted of a

Dosimetric comparison between intra-cavitary breast brachytherapy techniques for accelerated partial breast irradiation and a novel stereotactic radiotherapy device for breast cancer: GammaPod™.

Numai utilizatorii înregistrați pot traduce articole

The GammaPod™ device, manufactured by Xcision Medical Systems, is a novel stereotactic breast irradiation device. It consists of a hemispherical source carrier containing 36 Cobalt-60 sources, a tungsten collimator with two built-in collimation sizes, a dynamically controlled patient support table

In vivo near-infrared photothermal therapy and computed tomography imaging of cancer cells using novel tungsten-based theranostic probe.

Numai utilizatorii înregistrați pot traduce articole

Photothermal therapy, as a physical therapeutic technique to kill cancer, has generated a great deal of interest. Photothermal agents hence play a critical role in this modern therapy. We report the use of transition metal oxides as photothermal agents based on PEGylated WO3-x nanoparticles. The
