Lesion Segmentation in Automated 3D Breast Ultrasound: Volumetric Analysis.

Lesion Segmentation in Automated 3D Breast Ultrasound: Volumetric Analysis. Ultrason Imaging. 2017 Nov 01;:161734617737733 Authors: Agarwal R, Diaz O, Lladó X, Gubern-Mérida A, Vilanova JC, Martí R Abstract Mammography is the gold standard screening technique in breast cancer, but it has some limitations for women with dense breasts. In such cases, sonography is usually recommended as an additional imaging technique. A traditional sonogram produces a two-dimensional (2D) visualization of the breast and is highly operator dependent. Automated breast ultrasound (ABUS) has also been proposed to produce a full 3D scan of the breast automatically with reduced operator dependency, facilitating double reading and comparison with past exams. When using ABUS, lesion segmentation and tracking changes over time are challenging tasks, as the three-dimensional (3D) nature of the images makes the analysis difficult and tedious for radiologists. The goal of this work is to develop a semi-automatic framework for breast lesion segmentation in ABUS volumes which is based on the Watershed algorithm. The effect of different de-noising methods on segmentation is studied showing a significant impact ([Formula: see text]) on the performance using a dataset of 28 temporal pairs resulting in a total of 56 ABUS volumes. The volumetric analysis is also used to evaluate the performance of the developed framework. A mean Dice Similarity Coefficient of [Formula: s...

It was first developed to overcome the limitation of operator dependency and lack of standardization and reproducibility of handheld ultrasound. ABUS provides a three-dimensional representation of breast tissue and allows images reformatting in three planes, and the generated coronal plane has been suggested to...

ConclusionsThe study of radiomics in BC patients is a new and emerging translational research topic. Radiomics in BC is frequently done to potentially improve diagnosis and characterization, mostly using MRI. Substantial quality limitations were found; high-quality prospective and reproducible studies are needed to further potential application.

Conclusion ACC can be extensively infiltrative and present much larger than its radiological size, as reported in our case. Use of better imaging modalities judiciously, in these cases, are needed to more accurately predict the true pathological size of ACC to prevent inadequate surgery.

Hologic (NSDQ:HOLX) said recently that it won FDA 510(k) clearance for its Quantra 2.2 breast density assessment software and that it inked a development and distribution deal with Clarius Mobile Health for its wireless, handheld ultrasound scanner. The Marlborough, Mass.-based company said the Quantra 2.2 software uses a proprietary algorithm to analyze mammography images for the distribution and texture of breast tissue to produce patient-specific breast density assessments. “As the global leader in breast cancer screening technology, we relentlessly pursue the development of clinically superior products that ...

The objective of the initiative is to improve the diagnosis accuracy in detecting breast cancer, specifically when reading ultrasound breast scans and mammograms. The project will take place in rural towns, areas where the cancer is common, and regions where medical practitioners are short staffed.According to Xinhuanet,breast cancer is the most malignant tumor found in Chinese females, and there were 272,000 new cases of breast cancer in China in 2015.Through feeding the machine hundreds of scans, the institute hopes it will eventually be able to interpret breast reports. The machine can read a report at lightening speeds...
