Functional human brain imaging is mainly based on blood-oxygen-level-dependent (BOLD) functional magnetic resonance imaging (fMRI), which is a mature technology with recognized constraints in certain clinical and research applications. Photoacoustic computed tomography (PACT) is a promising complementary modality to fMRI as it does not involve magnetic fields and allows quantification of deoxyhemoglobin and oxyhemoglobin concentrations, convertible to oxygen saturation and blood volume. PACT has been explored in animal models but not in the human brain due to the limited field of view (FOV), imaging speed, sensitivity, and penetration depth. Here, we demonstrate PACT of the human brain using a massively parallel three-dimensional system with a 10-cm–diameter FOV and spatiotemporal resolution of 350 μm and 2 s. Functional PACT imaging was performed in post-hemicraniectomy patients and validated against 7 Tesla BOLD fMRI. Achieved functional results exhibit strong spatial correspondence in the same FOV and a high temporal correlation between hemoglobin and BOLD functional signals, however, with earlier detection of signal changes. Our findings demonstrate the potential of PACT for broader-scope human brain imaging.
