Journal ArticleDOI
Functional photoacoustic microscopy for high-resolution and noninvasive in vivo imaging
TL;DR: Functional photoacoustic microscopy (fPAM) is reported, which provides multiwavelength imaging of optical absorption and permits high spatial resolution beyond this depth limit with a ratio of maximum imaging depth to depth resolution greater than 100.
Journal ArticleDOI
Noninvasive laser-induced photoacoustic tomography for structural and functional in vivo imaging of the brain
TL;DR: In vivo noninvasive transdermal and transcranial imaging of the structure and function of rat brains by means of laser-induced photoacoustic tomography (PAT) is reported, which retains intrinsic optical contrast characteristics while taking advantage of the diffraction-limited high spatial resolution of ultrasound.
Journal ArticleDOI
Noninvasive imaging of hemoglobin concentration and oxygenation in the rat brain using high-resolution photoacoustic tomography
TL;DR: Simultaneous transcranial imaging of two functional parameters, the total concentration of hemoglobin and the hemoglobin oxygen saturation, in the rat brain in vivo is realized noninvasively using laser-based photoacoustic tomography (PAT).
Journal ArticleDOI
Photoacoustic tomography of a nanoshell contrast agent in the in vivo rat brain
Yiwen Wang,Xueyi Xie,Xueding Wang,Geng Ku,Kelly L. Gill,D. Patrick O'Neal,George Stoica,Lihong V. Wang +7 more
TL;DR: This study demonstrates the feasibility of using nanoshells in vivo as a new contrast-enhancing agent for photoacoustic tomography and presents a gradual enhancement of the optical absorption in the brain vessels by up to 63%.
Journal ArticleDOI
Simultaneous Molecular and Hypoxia Imaging of Brain Tumors In Vivo Using Spectroscopic Photoacoustic Tomography
Meng-Lin Li,Jung-Taek Oh,Xueyi Xie,Geng Ku,Wei Wang,Chun Li,Gina Lungu,George Stoica,Lihong V. Wang +8 more
TL;DR: Spectroscopic photoacoustic tomography (SPAT) as discussed by the authors offers both strong optical absorption contrast and high ultrasonic spatial resolution, which can potentially lead to better understanding of the interrelationships between hemodynamics and specific biomarkers associated with tumor progression.
