Computational Analysis of Functional Imaging in the Primary Auditory Cortex
Functional imaging can reveal detailed organizational structure in cerebral cortical areas, but neuronal response features and local neural interconnectivity can influence the resulting images, possibly limiting the inferences that can be drawn about neural function. Historically, discerning the …

Functional Imaging the Neonatal Brain with Wearable Diffuse Optical Tomography
… Non-invasive and wearable optical brain imaging technologies may allow for the cot-side study of newborn infants in clinical settings. This has particularly important implications for preterm infants in intensive care, for whom traditional neuroimaging techniques are not readily feasible. …

Dynamic Contrast-Enhanced MR Microscopy: Functional Imaging in Preclinical Models of Cancer
… (DCE) MRI has been widely used as a quantitative imaging method for monitoring tumor response to therapy. The pharmacokinetic parameters derived from this technique have been used in more than 100 phase I trials and investigator led studies. The simultaneous challenges of increasing the temporal …

Functional Imaging to enable more accurate localisation and characterisation of prostate tumours
… Therefore, the development of non-invasive imaging methods to stratify prostate cancer is important for patient management. Recently, multiparametric MRI has revolutionised the work-up of prostate cancer, becoming a routine part of clinical practice and migrating earlier in the diagnostic …

Digitally quantified neuropathological correlates of structural and functional imaging biomarkers in progressive supranuclear palsy
Neuroimaging measures are increasingly useful as *in vivo* biomarkers for differential diagnosis in neurodegenerative tauopathies. However, the relationship between imaging changes and neuropathology requires more thorough validation and beyond Alzheimer’s disease. In tauopathies, tau is the key …
