Optoacoustic imaging of the breast: correlation with histopathology and histopathologic biomarkers [PDF]

European Radiology, 2019
This study was conducted in order to investigate the role of gray-scale ultrasound (US) and optoacoustic imaging combined with gray-scale ultrasound (OA/US) to better differentiate between breast cancer molecular subtypes.All 67 malignant masses included in the Maestro trial were retrospectively reviewed to compare US and OA/US feature scores and ...

Photothermal bubble: Dynamics, manipulation, and applications

Droplet, EarlyView.
As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.

Soft ultrasound priors in optoacoustic reconstruction: Improving clinical vascular imaging

Photoacoustics, 2020
Using the same ultrasound detector, hybrid optoacoustic-ultrasound (OPUS) imaging provides concurrent scans of tissue slices or volumes and visualizes complementary sound- and light-based contrast at similar resolutions.

Epileptogenic lesions in the Australian epilepsy project: A harmonized 3‐T magnetic resonance imaging protocol and its diagnostic yield

Epilepsia, EarlyView.
Abstract Objective Detection of epilepsy‐causing structural brain lesions on magnetic resonance imaging (MRI) is critical for diagnosis, prognosis, and treatment planning in people with epilepsy. We aimed to establish an epilepsy‐directed multisite harmonized 3‐T MRI acquisition protocol for the Australian Epilepsy Project (AEP) and describe the ...

Flexible wearable electronics for cardiovascular monitoring from surface signals to deep physiological insights

FlexMat, EarlyView.
This review organizes flexible wearable electronics for cardiovascular monitoring into four interconnected information layers: surface electrophysiology, hemodynamic sensing, vascular imaging, and biofluid biomarker analysis. This framework clarifies how electrical rhythm, vascular loading, structural and flow‐related features, and biochemical states ...

The Dual-Targeted Peptide Conjugated Probe for Depicting Residual Nasopharyngeal Carcinoma and Guiding Surgery

Biosensors, 2022
Detecting residual nasopharyngeal carcinoma (rNPC) can be difficult because of the coexistence of occult tumours and post-chemoradiation changes, which poses a challenge for both radiologists and surgeons using current imaging methods.

Invariant representations in deep learning for optoacoustic imaging

Review of Scientific Instruments, 2023
Image reconstruction in optoacoustic tomography (OAT) is a trending learning task highly dependent on measured physical magnitudes present at sensing time. A large number of different settings and also the presence of uncertainties or partial knowledge of parameters can lead to reconstruction algorithms that are specifically tailored and designed to a ...

Cognitive reappraisal modulates neural responses to aversive sensory stimulation in autistic youth

Journal of Child Psychology and Psychiatry, EarlyView.
Background Sensory over‐responsivity (SOR) is highly prevalent and impairing in autism spectrum disorder (ASD). SOR has been associated with sensory‐limbic hyperresponsivity and reduced prefrontal top‐down regulation during sensory stimulation. There are few evidence‐based treatments for SOR, but cognitive reappraisal, an emotion regulation strategy ...
