Laser Ultrasound Super‐Resolution Imaging for Multi‐Parametric Non‐Invasive Volumetric Characterization of Brain Cancer

open access: yesAdvanced Science, Volume 12, Issue 47, December 18, 2025.
Laser ultrasound super‐resolution imaging (LUSSI) leverages laser‐generated ultrasound for functional 3D transcranial imaging of brain tumor vasculature. Combined with optoacoustic tomography, it is demonstrated in a glioblastoma model, revealing structural abnormalities, compressed vessels, hemorrhages, and hypoxic regions.

Noninvasive Detection and Thermal Ablation Therapy of Endometriosis Using Silica‐Coated Gold Nanorods

open access: yesAdvanced NanoBiomed Research, Volume 5, Issue 12, December 2025.
AuNR@Si(F)‐PEG nanoparticles are developed as theranostic agents for the noninvasive detection and photothermal therapy of endometriosis. The particles are preferentially taken up by the endometriosis lesions under photoacoustic image‐guidance, and used as thermal ablation therapeutics to shrink the lesions.

Quantitative high-resolution photoacoustic spectroscopy by combining photoacoustic imaging with diffuse optical tomography [PDF]

open access: yes, 2011
The specificity of both molecular and functional photoacoustic (PA) images depends on the accuracy of the photoacoustic absorption spectroscopy. Because the PA signal is a product of both the optical absorption coefficient and the local light fluence ...

Imaging increased metabolism in the spinal cord in mice after middle cerebral artery occlusion

open access: yesPhotoacoustics, 2023
Emerging evidence indicates crosstalk between the brain and hematopoietic system following cerebral ischemia. Here, we investigated metabolism and oxygenation in the spleen and spinal cord in a transient middle cerebral artery occlusion (tMCAO) model ...

Gamma probe and ultrasound guided fine needle aspiration cytology of the sentinel node (GULF) trial [PDF]

open access: yes, 2017
Background: Sentinel node (SN) biopsy (SNB) detects clinically occult metastases of breast cancer and melanoma in 20-30%. Wound infections, seroma and lymph edema occur in up to 10%.

S1 guideline for imaging diagnostics for skin diseases

open access: yesJDDG: Journal der Deutschen Dermatologischen Gesellschaft, Volume 23, Issue 12, Page 1616-1630, December 2025.
Summary Non‐invasive imaging techniques allow a quick and easy in vivo examination of the skin with different penetration depths and resolution depending on the applied technology. Established methods such as dermoscopy and high‐resolution sonography of the skin have been an integral part of everyday life for decades.

Multiscale photoacoustic tomography using reversibly switchable bacterial phytochrome as a near-infrared photochromic probe [PDF]

open access: yes, 2016
Photoacoustic tomography (PAT) of genetically encoded probes allows for imaging of targeted biological processes deep in tissues with high spatial resolution; however, high background signals from blood can limit the achievable detection sensitivity ...

Water, Collagen, and Lipid Content in the Human Skin and Muscles Assessed with Near‐Infrared Diffuse Reflectance Spectroscopy and Multi‐Spectral Optoacoustic Tomography

open access: yesAdvanced Science, Volume 12, Issue 41, November 6, 2025.
Authors present a novel approach combining multispectral optoacoustic tomography and diffuse reflectance spectroscopy for noninvasive assessment of body composition, including water, lipid, and collagen in skin and muscles. Its high molecular and spatial specificity offers improved diagnostic potential for conditions like obesity and sarcopenia ...
