BACKGROUND: Augmented reality (AR) enables the superimposition of virtual reality reconstructions onto clinical images of a real patient, in real time. This allows visualization of internal structures through overlying tissues, thereby providing a virtual transparency vision of surgical anatomy. AR has been applied to neurosurgery, which utilizes a relatively fixed space, frames, and bony references; the application of AR facilitates the relationship between virtual and real data. Augmented Breast imaging (ABI) is described...

Biomechanical breast models have been employed for applications in image registration and diagnostic analysis, breast augmentation simulation, and for surgical and biopsy guidance. Accurate applications of stress-strain relationships of tissue within the breast can improve the accuracy of biomechanical models that attempt to simulate breast deformations. Reported stiffness values for adipose, glandular, and cancerous tissue types vary greatly. Variations in reported stiffness properties have been attributed to differences in testing methodologies and assumptions, measurement errors, and natural interpatient differences in tissue elasticity...

Background: Fine needle aspiration cytology (FNAC) is a simple, rapid, inexpensive, and reliable method of diagnosis of breast mass. Cytoprognostic grading in breast cancers is important to identify high-grade tumors. Computer-assisted image morphometric analysis has been developed to quantitate as well as standardize various grading systems. Aims: To apply nuclear morphometry on cytological aspirates of breast cancer and evaluate its correlation with cytomorphological grading with derivation of suitable cutoff values between various grades...

INTRODUCTION: The reinsertion of an infected implant when peri-prosthetic infection occurs early after breast augmentation or breast reconstruction remains controversial. In this experimental study, the authors tried to remove bacteria, and their biofilm, from the colonized surface of breast prostheses, without damaging their integrity. MATERIALS AND METHODS: A total of 112 shell samples of silicone breast prostheses, smooth (SPSS) and textured (TPSS), were colonized by S...

In this study, an unusual case of a patient who was previously operated on a ruptured breast implant following silicone granuloma associated with pectoral muscle involvement is reported. A 72-year-old woman had undergone breast augmentation surgery when she was 52-year-old and silicone implant rupture 10 years later. After 10 years of ruptured silicone implant, her mammography showed diffuse, multiple high-density nodules in the left breast. The pectoral muscle was significantly hypertrophic. The magnetic resonance imaging showed that the pectoral muscle was quite hypertrophic and had heterogeneous enhancement...

BACKGROUND: Dynamic breast deformity (DBD) is characterized by visible distortion and deformity of the breast due to contraction of the pectoralis major muscle after submuscular breast augmentation; fortunately, in most cases, this is not a clinically significant complaint from patients. The purpose of this study is to present a simple method for objectively measuring DBD in patients submitted to dual plane breast augmentation (DPBA). METHODS: We studied 32 women, between 18 and 50 years old, who underwent primary DPBA with at least 1 year of follow-up...

Soft-tissue augmentation and implants are increasingly seen by the radiologist as more techniques emerge for a variety of indications and locations. Some surgical and implant procedures are performed for purely cosmetic reasons in otherwise healthy patients seeking to improve their body image, and some are performed for reconstruction after cancer or other chronic illnesses. Abdominoplasty, liposuction, and autologous fat grafting can be performed for abdominal and gluteal contouring. Injection of liquid injectable silicone has historically been fraught with legal issues, although it continues to be used for augmentation in a variety of anatomic locations...

Breast implant-associated anaplastic large-cell lymphoma (BIA-ALCL) is a rare peripheral T cell lymphoma. BIA-ALCL is a disease of the fibrous capsule surrounding the implant and occurs in patients after both breast reconstruction and augmentation. More than 300 cases have been reported so far, including two in a transgender patient. Here we describe BIA-ALCL presented with a mass in a transgender patient and the first case of BIA-ALCL in the Czech Republic. In 2007, a 33-year-old transgender male to female underwent bilateral breast augmentation as a part of his transformation to female...

Pathologists often deal with high complexity and sometimes disagreement over osteosarcoma tumor classification due to cellular heterogeneity in the dataset. Segmentation and classification of histology tissue in H&E stained tumor image datasets is a challenging task because of intra-class variations, inter-class similarity, crowded context, and noisy data. In recent years, deep learning approaches have led to encouraging results in breast cancer and prostate cancer analysis. In this article, we propose convolutional neural network (CNN) as a tool to improve efficiency and accuracy of osteosarcoma tumor classification into tumor classes (viable tumor, necrosis) versus nontumor...

INTRODUCTION: Several factors, such as aging, pregnancy, and weight loss, reduce the elasticity of the breast tissue, and ptosis occurs. Due to aging and gravity, it is not possible to completely prevent breast ptosis. The goal is to delay the recurrence of ptosis as much as possible. PATIENTS AND METHODS: This study included 20 female patients aged 25-55 years. The patients who underwent surgery had different levels of ptosis. Although the patients wanted their breasts to be lifted and an increase in projection, they did not want implants to be used...

Cell cycle progression and the acquisition of a migratory phenotype are hallmarks of human carcinoma cells that are perceived as independent processes but may be interconnected by molecular pathways that control microtubule nucleation at centrosomes. Here, cell cycle progression dramatically impacts the engraftment kinetics of 4T1-luciferase2 breast cancer cells in immunocompetent BALB/c or immunocompromised NOD-SCID gamma (NSG) mice. Multi-parameter imaging of wound closure assays was used to track cell cycle progression, cell migration, and associated phenotypes in epithelial cells or carcinoma cells expressing a fluorescence ubiquitin cell cycle indicator...

Anaplastic large cell lymphoma is a rare disease associated with breast implants. We present the case of a woman who had had breast augmentation and multiple revisions over a period of 13 years and presented with recurrent fluid collections. The cause was determined to be anaplastic large cell lymphoma, which required removal of the implants, capsulectomy, and evaluation by a medical oncologist. The patient was not found to have metastatic disease on imaging studies. Breast implant-associated anaplastic large cell lymphoma is a poorly understood disease entity, and optimal treatment is unclear...

It is imperative to continue screening for breast cancer and/or detect tumor recurrence in patients after they have undergone breast augmentation or reconstruction. As there is an increasing role for both screening and diagnostic imaging of the post-operative breast, it is important for the radiologist to be familiar with the commonly performed surgical techniques in breast augmentation and reconstruction. Imaging of the augmented and reconstructed breast, as well as complications, will be reviewed with a focus on Magnetic Resonance Imaging (MRI)...

INTRODUCTION: Since the beginning of the 21st century, three-dimensional imaging systems have been used more often in plastic surgery, especially during preoperative planning for breast surgery and to simulate the postoperative appearance of the implant in the patient's body. The main objective of this study is to assess the patients' attitudes regarding 3D simulation for breast augmentation. METHOD: A study was conducted, which included women who were operated on for primary breast augmentation...

PURPOSE: The limited number of 3D patient-based breast phantoms available could be augmented by synthetic breast phantoms in order to facilitate virtual clinical trials using model observers for breast imaging optimization and evaluation. METHODS: These synthetic breast phantoms were developed using Principal Component Analysis (PCA) to reduce the number of dimensions needed to describe a training set of images. PCA decomposed a training set of M breast CT volumes (with millions of voxels each) into an M-1-dimensional space of eigenvectors, which we call eigenbreasts...

The high incidence of breast cancer is a known fact. The 5-year survival rate for women with correctly treated breast cancer is 90% around the world, and 50% in Romania, respectively. Correct diagnostic evaluation of the breasts allows for a competent therapeutic management. The primary diagnosis of breast cancer includes clinical examination of the breasts, breast ultrasound and mammography. Magnetic resonance imaging (MRI) examination is not a first line type of investigation, but targeted to selected patient groups...

Fibromatosis of the breast is a rare benign disease compromising <0.2% of all primary breast tumors. Although the chest wall is a common location, occurrences of implant-associated fibromatosis of the breast are extremely rare; only 33 cases have been reported. We present a case of a 42-year-old female who underwent breast augmentation with silicone breast implants, and 2 years later developed an aggressive implant-associated fibromatosis of the breast and chest wall. On imaging studies, the tumor mimicked breast carcinoma, and despite chemotherapy, the fibromatosis rapidly enlarged and was locally invasive requiring wide surgical excision...
