“…There are some commonly available medical imaging modalities, such as X-ray mammography, ultrasound (US) imaging, and magnetic resonance imaging (MRI), which are used separately or in combination for the screening of the breast cancer. For an asymptomatic patient, the commonly used diagnosis protocol using imaging is to refer the patient for a biopsy procedure to confirm the breast cancer diagnosis if the patient comes up with a suspected X-ray mammogram and US image [10]. X-ray mammography, in addition to possessing ionization hazards, has limited sensitivity specifically for women under 50 [11][12][13].…”

“…US imaging is another imaging modality used for imaging breast cancer. When X-ray mammography produces conflicting inference with that of the US image, MRI is done before referring the patient for a biopsy procedure [10]. Due to low soft tissue contrast and strong operator dependency, US imaging is not a very efficient tool for breast cancer detection.…”

“…Due to low soft tissue contrast and strong operator dependency, US imaging is not a very efficient tool for breast cancer detection. Both the US image and X-ray mammogram provide morphological information related to the breast [10]. As in the early stages, breast cancer does not produce significant morphological changes, and X-ray mammogram and US imaging may not be suitable for early detection of breast cancer.…”

Photoacoustic Imaging for Management of Breast Cancer: A Literature Review and Future Perspectives

In this review article, a detailed chronological account of the research related to photoacoustic imaging for the management of breast cancer is presented. Performing a detailed analysis of the breast cancer detection related photoacoustic imaging studies undertaken by different research groups, this review attempts to present the clinical evidence in support of using photoacoustic imaging for breast cancer detection. Based on the experimental evidence obtained from the clinical studies conducted so far, the performance of photoacoustic imaging is compared with that of conventional breast imaging modalities. While we find that there is enough experimental evidence to support the use of photoacoustic imaging for breast cancer detection, additional clinical studies are required to be performed to evaluate the diagnostic potential of photoacoustic imaging for identifying different types of breast cancer. To establish the utility of photoacoustic imaging for breast cancer screening, clinical studies with high-risk asymptomatic patients need to be done.

We are developing methods of noninvasively delivering magnetic neuroparticles™ via intranasal administration followed by image-guided magnetic propulsion to selected locations in the brain. Once placed, the particles can activate neurons via vibrational motion or magnetoelectric stimulation. Similar particles might be used to read out neuronal electrical pulses via spintronic or liquid-crystal magnetic interactions, for fast bidirectional brain-machine interface. We have shown that particles containing liquid crystals can be read out with magnetic resonance imaging (MRI) using embedded magnetic nanoparticles and that the signal is visible even for voltages comparable to physiological characteristics. Such particles can be moved within the brain (e.g., across midline) without causing changes to neurological firing.

“…The bio-distribution and follow-up of exogenous absorbers can reveal additional anatomical and functional information such as blood perfusion (11,12), drainage in lymph vessels (13), and accumulation of contrast agents (10,14,15). Much recent research has been directed towards preclinical studies in small animals (16,17), but photoacoustic imaging has also promising clinical applications, such as diagnostic of breast cancer (18) and dermatology (19,20). Photoacoustic (PA) tomography is highly scalable (3).…”

Single-side access, isotropic resolution, and multispectral three-dimensional photoacoustic imaging with rotate-translate scanning of ultrasonic detector array

(200 words).Photoacoustic imaging can achieve high-resolution three-dimensional visualization of optical absorbers at penetration depths ~ 1 cm in biological tissues by detecting optically-induced high ultrasound frequencies. Tomographic acquisition with ultrasound linear arrays offers an easy implementation of single-side access, parallelized and high-frequency detection, but usually comes with an image quality impaired by the directionality of the detectors. Indeed, a simple translation of the array perpendicularly to its median imaging plane is often used, but results both in a poor resolution in the translation direction and in strong limited view artifacts. To improve the spatial resolution and the visibility of complex structures while keeping a planar detection geometry, we introduce, in this paper, a novel rotate-translate scanning scheme, and investigate the performance of a scanner implemented at 15 MHz center frequency. The developed system achieved a quasi-isotropic uniform 3D resolution of ~170 µm over a cubic volume of side length 8.5 mm, i.e. an improvement in the resolution in the translation direction by almost one order of magnitude. Dual wavelength imaging was also demonstrated with ultrafast wavelength shifting. The validity of our approach was shown in vitro. We discuss the ability to enable in vivo imaging for preclinical and clinical studies.
