Comparison of Comfort between Cone Beam Breast Computed Tomography and Digital Mammography

Publication date: Available online 16 September 2019Source: European Journal of RadiologyAuthor(s): Haijie Li, Lu Yin, Ni He, Peng Han, Yueqiang Zhu, Yue Ma, Aidi Liu, Hong Lu, Zhipeng Gao, Peifang Liu, Yaopan Wu, Zhaoxiang YeAbstractPurposeTo compare the comfort levels of cone beam breast computed tomography (CBBCT) and digital mammography.Materials and MethodsOn 409 patients, CBBCT was performed within 1 week after conventional mammography. Patients evaluated their comfort by using an 11-point numerical rating scale (NRS-11) after completing the two examinations. The lower the score was, the more comfortable the examination modality was. The data was divided into different groups according to CBBCT scan mode (non-contrast mode, contrast-enhanced mode), age (≤44, 45∼59 and ≥60), body mass index (BMI) (

AbstractBackgroundThe density of tumor-infiltrating lymphocytes (TIL) is a predictive factor for response to neoadjuvant systemic therapy (NAST) in breast cancer. High TIL density correlates with higher complete pathologic remission (pCR) in triple negative and HER2 positive breast cancer. Additionally, not only TIL density but also subsets of immune cells in tumor stroma seem to play an important role in cancer and immune cell interaction and response to chemotherapy. Our aim is to determine TIL density and expression of CD 20, CD3, CD8, PD-L1, FOXP3 and PGM1 on core biopsy specimen and find a correlation with pCR.Trial d...

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 ...

A 68-year-old women presented with a right breast mass in the last 6 months, which was gradually increasing in size. Physical examination revealed a 10  cm mass in the upper outer quadrant of the right breast. This mass was firm, oval, non-tender, and free from the skin and underlying tissue. The medio-lateral mammogram revealed a homogenous dense, well-circumscribed lesion in the right breast (Fig. 1). In the axial thorax CT-scan image, we found a hypodense, well-defined mass with capsular wall of 7 cm containing endogenous daughter cysts (Fig.

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,...

Breast computed tomography (BCT) is an emerging application of X-ray tomography in radiological practice. A few clinical prototypes are under evaluation in hospitals and new systems are under development aiming at improving spatial and contrast resolution and reducing delivered dose. At the same time, synchrotron-radiation phase-contrast mammography has been demonstrated to offer substantial advantages when compared with conventional mammography. At Elettra, the Italian synchrotron radiation facility, a clinical program of phase-contrast BCT based on the free-space propagation approach is under development. In this paper, ...

Objectives The purpose of this work is to present the data obtained from the first clinical in vivo application of a new dedicated spiral breast computed tomography (B-CT) equipped with a photon-counting detector. Materials and Methods The institutional review board approved this retrospective study. Twelve women referred for breast cancer screening were included and underwent bilateral spiral B-CT acquired in prone position. Additional sonography was performed in case of dense breast tissue or any B-CT findings. In 3 women, previous mammography was available for comparison. Soft tissue (ST) and high-resolution (HR) i...

Abstract We computed normalized glandular dose (DgN) coefficients for mean glandular dose estimates in contemporary 2D mammography units, taking into account a realistic homogeneous model for the breast. We developed a Monte Carlo code based on the simulation toolkit GEANT4 ver. 10.00. The breast was modelled as a cylinder with a semi-cylindrical section with a radius of 10 cm, enveloped in a 1.45-mm thick skin layer, as found out in recent reports from the University of California Davis team in the analysis of breast computed tomography clinical scans. The compressed breast thickness was between 3 cm and 8 cm. Th...

Dilbert by Scott Adams, courtesy www.dilbert.comMy very first blog post as Doctor Dalai went online on 1/29/2005, beginning with a rant about ScImage lifted from one of my early AuntMinnie.com entries. In the subsequent fourteen years, my writing has become slightly more sophisticated (emphasizeslightly), but my basic premise has not wavered: PACS interfaces by and large are not as user-friendly as they could be, in other words, theySUCK. Forgive the epithet, but that is a very accurate statement, and most would agree.Most, but not the vendors. In browsing through my years of navel-gazing, I came across several entries whe...

For many years, health plans have been searching for ways to incentivize their members to search for lower priced services such as imaging and surgical procedures like total hip replacement. I believe that the best incentive for this searching and cost-saving behavior is some sort of benefit like cash. A recent article covered this topic (see:How employers save money by paying employees to shop for healthcare) and below is an excerpt from it: According to a new RAND Corp. study published in Health Affairs, paying employees between $25 and $500 for using a transparency tool, and encouraging them to select a lower-...
