3D visualization of breast tumors are shown to be effective by previous studies. In this paper, we introduce a new augmented reality application that can help doctors and surgeons to have a more accurate visualization of breast tumors; this system uses a marker-based image-processing technique to render a 3D model of the tumors on the body. The model can be created using a combination of breast 3D mammography by experts. We have tested the system using an Android smartphone and a head-mounted device. This proof of concept can be useful for oncologists to have a more effective screening, and surgeons to plan the surgery...

(3-Aminomethylphenyl)boronic acid (AMPB)-installed hyaluronic acid-ceramide (HACE)-based nanoparticles (NPs), including manassantin B (MB), were fabricated for tumor-targeted delivery. The amine group of AMPB was conjugated to the carboxylic acid group of hyaluronic acid (HA) via amide bond formation, and synthesis was confirmed by spectroscopic methods. HACE-AMPB/MB NPs with a 239-nm mean diameter, narrow size distribution, negative zeta potential, and > 90% drug encapsulation efficiency were fabricated...

BACKGROUND: The inability to visualize the patient and surgical site directly, limits the use of current near infrared fluorescence-guided surgery systems for real-time sentinel lymph node biopsy and tumor margin assessment. METHODS: We evaluated an optical see-through goggle augmented imaging and navigation system (GAINS) for near-infrared, fluorescence-guided surgery. Tumor-bearing mice injected with a near infrared cancer-targeting agent underwent fluorescence-guided, tumor resection...

While mass spectrometry (MS) imaging is widely used to investigate the molecular composition of ex vivo slices of cancerous tumors, little is known about how variations in the cellular properties of cancer tissue can influence cancer biomarker ion images. To better understand the basis for variations in the abundances of cancer biomarker ions seen in MS images of relatively homogeneous ex vivo tumor samples, sections of snap frozen human breast cancer murine xenografts were subjected to desorption electrospray ionization mass spectrometry (DESI-MS) imaging...

PURPOSE: Review of dose metrics as part of the routine evaluation of CT protocols has become commonplace and is required by the Joint Commission and the American College of Radiology for accreditation. Most CT quality assurance programs include a review of CTDIvol and/or SSDE, both of which are affected by changes in mAs and kV. mAs, and sometimes kV, are largely determined by the Tube Current Modulation (TCM) functions of the scanner. TCM, in turn, relies on localizer scans to provide an accurate estimate of patient size...

BACKGROUND: Bra sizing is a common method to preoperatively select implants for breast augmentation; however, no series has analyzed the accuracy of this modality postoperatively. Alternatively, previous investigations have validated the accuracy and utility of three-dimensional (3D) imaging for preoperative simulation in breast augmentation. OBJECTIVES: This investigation utilizes 3D analysis to determine if preoperative bra sizing provides equivocal information compared to surgical 3D simulation for patient education and planning prior to a breast augmentation...

PURPOSE: Develop a computer-aided detection (CAD) system for masses in digital breast tomosynthesis (DBT) volume using a deep convolutional neural network (DCNN) with transfer learning from mammograms. METHODS: A data set containing 2282 digitized film and digital mammograms and 324 DBT volumes were collected with IRB approval. The mass of interest on the images was marked by an experienced breast radiologist as reference standard. The data set was partitioned into a training set (2282 mammograms with 2461 masses and 230 DBT views with 228 masses) and an independent test set (94 DBT views with 89 masses)...

Siliconoma from ruptured breast implants has been reported in multiple body sites, including but not limited to the breast parenchyma, axillary lymph nodes, upper arm, and even lower leg. In this regard, we report a rare case of distant silicone migration to the lower extremities after traumatic breast implant rupture. A 55-year-old Asian woman who received bilateral augmentation mammoplasty 20 years ago presented with ruptured breast implants from a car accident 2 years earlier. Magnetic resonance imaging confirmed intracapsular and extracapsular rupture of the right breast implant, showing "linguine sign...

BACKGROUND: Breast augmentation with fat transfer does not bear the risks associated with silicone implantation. The method can potentially be especially useful in Asian women, who often reject augmentation mammoplasty with implants. This prospective clinical trial evaluated the effects of external breast expansion on breast density and vessel count using magnetic resonance imaging. METHODS: Thirty-four enrolled patients were instructed to apply one of two devices, the conventional BRAVA device (used in the AESTES trial) or a novel external expansion device (EVERA) designed for Asian women, continuously for 8 h per day for 12 weeks...

Several techniques for measuring breast volume (BV) are based on examining the breast on magnetic resonance imaging. However, when techniques designed to measure total BV are used to quantify BV changes, for example, after fat grafting, a systematic error is introduced because BV changes lead to contour alterations of the breast. The volume of the altered breast includes not only the injected volume but also tissue previously surrounding the breast. Therefore, the quantitative difference in BV before and after augmentation will differ from the injected volume...

BACKGROUND: Revision surgeries after breast augmentation are associated with an increased risk of complications (eg, nipple areolar complex [NAC]) necrosis. Consequently, maintaining perfusion to the NAC is a critical aspect of secondary breast surgery. OBJECTIVES: The purpose of this study was to examine in vivo changes in perfusion to the NAC after implant breast augmentation using magnetic resonance imaging (MRI) technology. METHODS: High-resolution 3 Tesla MRI images of 10 women (20 breasts) with previous breast augmentation were compared to a control population of 15 women (30 breasts)...

BACKGROUND: There is a perception that cosmetic breast surgery has more favorable aesthetic outcomes than reconstructive breast surgery. We tested this hypothesis by comparing aesthetic outcomes after breast augmentation and reconstruction. METHODS: Postoperative images of 10 patients (cosmetic, n = 4; reconstructive, n = 6; mean follow-up, 27 months) were presented anonymously to participants who were blinded to clinical details. Participants were asked if they believed cosmetic or reconstructive surgery had been performed...

INTRODUCTION: The use of breast implants is on the rise due to increases in breast reconstructive and aesthetic surgery. Implant rupture is a possible complication. Among assessment modalities for implant rupture detection, MRI is considered the gold standard. METHODS: We conducted a prospective analysis of 57 women after breast augmentation or postmastectomy reconstruction (109 implants), admitted to our department between 2010 and 2015 due to suspected implant rupture...

BACKGROUND: Breast tomosynthesis (pseudo-3D mammography) improves breast cancer detection when added to 2D mammography. In this study, we examined whether integrating 3D mammography with either standard 2D mammography acquisitions or with synthetic 2D images (reconstructed from 3D mammography) would detect more cases of breast cancer than 2D mammography alone, to potentially reduce the radiation burden from the combination of 2D plus 3D acquisitions. METHODS: The Screening with Tomosynthesis Or standard Mammography-2 (STORM-2) study was a prospective population-based screening study comparing integrated 3D mammography (dual-acquisition 2D-3D mammography or 2D synthetic-3D mammography) with 2D mammography alone...

During adolescence, psychological and physical changes occur and breast takes a major place in the young woman body image. Except rare malign tumors, breast pathologies at this age are mainly benign or malformative. Malformative issues are revealed during breast growth, as isolated asymmetry or associated to other regional anomalies, with abnormal shape or volume of the breast, or even supernumerary breast. Therapeutic solutions will not differ from the ones used for adults. Breast lipofilling, recently admitted by plastic surgery community is an interesting tool that can be used on young women...

BACKGROUND: Ptotic breast deformity results from involution of breast parenchyma and leads to a loss of volume, along with a converse laxity of the skin envelope. As the breast tissue descends inferiorly with gravity, there is an apparent volume loss in the upper pole and the central breast, and the lower pole becomes fuller and often wider. This study presents modifications for a well-known mastopexy technique which provides not only autoaugmentation for the breast but also suspension for the breast parenchyma and reduces bottoming-out deformity, and also obtains a regular areola shape in all types of breasts...
