Qi Tang, Yan Jiang, Yali Xu, Hongmei Xia
PURPOSE: This study aimed to assess the early changes of left ventricular (LV) and right ventricular (RV) mechanics associated with anthracycline treatment for breast cancer and to determine whether two-dimensional speckle tracking echocardiography (2D-STE) analysis could predict chemotherapy-induced cardiotoxicity. BACKGROUND: Anthracycline generates progressive LV dysfunction associated with a poor prognosis. Early detection of minor change of myocardial mechanics is thus important...

Yang Lou, Kun Wang, Alexander A Oraevsky, Mark A Anastasio
Optoacoustic tomography (OAT), also known as photoacoustic tomography, is a rapidly emerging hybrid imaging technique that possesses great potential for a wide range of biomedical imaging applications. In OAT, a laser is employed to illuminate the tissue of interest and acoustic signals are produced via the photoacoustic effect. From these data, an estimate of the distribution of the absorbed optical energy density within the tissue is reconstructed, referred to as the object function. This quantity is defined, in part, by the distribution of light fluence within the tissue that is established by the laser source...

Naoki Sunaguchi, Yoshiki Yamakoshi, Takahito Nakajima
This study investigates shear wave phase map reconstruction using a limited number of color flow images (CFIs) acquired with a color Doppler ultrasound imaging instrument. We propose an efficient reconstruction method to considerably reduce the number of CFIs required for reconstruction and compare this method with Fourier analysis-based color Doppler shear wave imaging. The proposed method uses a two-step phase reconstruction process, including an initial phase map derived from four CFIs using an advanced iterative algorithm of optical interferometry...

PURPOSE: Roughly two-thirds of early breast cancer cases are associated with negative axillary nodes and do not benefit from axillary surgery at all. Accordingly, there is an ongoing search for non-surgical staging procedures to avoid lymph-node dissection or sentinel node biopsy (SNB). Non-invasive imaging techniques with very high sensitivity (Se) and negative predictive value (NPV) could eventually replace SNB. We aimed to establish the role of axillary US and MRI, alone or in combination, associated with ultrasound-guided fine-needle aspiration biopsy (US-FNAB) in the prediction of axillary node involvement...

OBJECTIVES: We propose an automatic breast mass detection algorithm in three-dimensional (3D) ultrasound (US) images using the Hough transform technique. METHODS: One hundred twenty-five cropped images containing 68 benign and 60 malignant masses are acquired with clinical diagnosis by an experienced radiologist. The 3D US images are masked, subsampled, contrast-adjusted, and median-filtered as preprocessing steps before the Hough transform is used. Thereafter, we perform 3D Hough transform to detect spherical hyperplanes in 3D US breast image volumes, generate Hough spheres, and sort them in the order of votes...

Desmoid tumor of breast is a rare benign, locally aggressive tumor with a high recurrence rate. It has been associated with scar from previous breast surgery or trauma. Especially in breast cancer patients with previous operation history, it may simulate recurrent breast cancer clinically and radiologically. We presented multimodality imaging findings (ultrasound, computed tomography, magnetic resonance imaging and positron emission tomography/computed tomography) of chest wall desmoid tumor mimicking recurrent breast cancer in a 38-year-old patient with a history of left modified mastectomy...

Ultrasound-guided Pecs block can provide perioperative analgesia for breast surgery. A single-injection technique (COMBIPECS) combines both Pecs 1 and Pecs 2 blocks in a single needle pass. This technique saves time and is equally effective as the modified Pecs block which uses 2 needle passes. We present a case series of 21 patients who received the COMBIPECS block as a part of multimodal analgesia for breast cancer surgery. The block was administered before the surgery after induction of general anesthesia...

Shear wave elastography (SWE) is a new non-invasive diagnostic imaging technique, that maps the elastic properties of tissues. Nowadays this modality develops increasingly in medicine across its disciplines and opens a new era of high-quality ultrasound examination because it increases the specificity and thus improves diagnostic assurance. This method is similar to manual palpation, shows elastic properties of biological tissues and provides a kind of reconstruction of the internal structure of soft tissues based on measurement of the response of tissue compression...

Noninvasive multimodal imaging of tumor blood vessels allows the qualitative and quantitative assessment of morphological, functional, and molecular features of tumor angiogenesis longitudinally in a living organism. In this chapter we focus on the application of magnetic resonance imaging (MRI), computed tomography (CT), ultrasound (US), and positron emission tomography (PET) in tumor blood vessel visualization on the example of breast cancer bone metastasis in a nude rat model. Thereby, materials and methods are described that are needed to obtain complementary data on tumor vascularization from these imaging techniques...
