| Sumario: | RGB optical imaging is a marker-free, contactless, and non-invasive technique that is able to monitor hemodynamic brain response following neuronal activation using task-based and resting-state procedures. Magnetic resonance imaging (fMRI) and functional near infra-red spectroscopy (fNIRS) resting-state procedures cannot be used intraoperatively but RGB imaging provides an ideal solution to identify resting-state networks during a neurosurgical operation. We applied resting-state methodologies to intraoperative RGB imaging and evaluated their ability to identify resting-state networks. We adapted two resting-state methodologies from fMRI for the identification of resting-state networks using intraoperative RGB imaging. Measurements were performed in 3 patients who underwent resection of lesions adjacent to motor sites. The resting-state networks were compared to the identifications provided by RGB task-based imaging and electrical brain stimulation. Intraoperative RGB resting-state networks corresponded to RGB task-based imaging (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>D</mi><mi>I</mi><mi>C</mi><mi>E</mi><mo>:</mo><mn>0.55</mn><mspace width="3.33333pt"></mspace><mo>±</mo><mspace width="3.33333pt"></mspace><mn>0.29</mn></mrow></semantics></math></inline-formula>). Resting state procedures showed a strong correspondence between them (<inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mi>D</mi><mi>I</mi><mi>C</mi><mi>E</mi><mo>:</mo><mn>0.66</mn><mspace width="3.33333pt"></mspace><mo>±</mo><mspace width="3.33333pt"></mspace><mn>0.11</mn></mrow></semantics></math></inline-formula>) and with electrical brain stimulation. RGB imaging is a relevant technique for intraoperative resting-state networks identification. Intraoperative resting-state imaging has several advantages compared to functional task-based analyses: data acquisition is shorter, less complex, and less demanding for the patients, especially for those unable to perform the tasks. |
