Imaging spectral information of materials and analysis of its properties have become an intriguing tool for consumer electronics used for food inspection, beauty care, etc. Those sensory physical quantities are difficult to quantify. Hyperspectral imaging cameras, which capture the figure and spectral information simultaneously, can be a good candidate for nondestructive remote sensing.

Olfactory dysfunction, affecting 75-90 % of Parkinson's disease (PD) patients, holds significant predictive value for PD development. Advanced imaging techniques, such as diffusion MRI (dMRI) and functional MRI (fMRI), offer insights into structural and functional changes within olfactory pathways. This review summarizes a decade of research on MRI-based connectivity of the olfactory system in PD, focusing on structural and functional alterations in olfactory brain areas and their links to early olfactory processing changes.

Stress radionuclide myocardial perfusion imaging (MPI) has been well-established as a useful modality for assessing the status of the coronary circulation in post-coronary artery bypass graft (CABG) patients. CABG by itself escalates progression of atherosclerosis or thrombosis in bypassed native coronary arteries. In most cases MPI will be employed in post-CABG patients who are experiencing symptoms.

Background: The use of the residual cancer burden (RCB) for assessing breast cancer after neoadjuvant therapy (NAT) is increasingly common, but the prognostic difference between RCB 0 and RCB I is unclear.
Methods: We systematically reviewed literature from PubMed, Embase, Web of Science, and oncology conferences until September 24, 2023. We used fixed- and random-effects models to calculate hazard ratio (HR) with 95% confidence interval (CI) for event-free survival (EFS), overall survival (OS), and distant disease-free survival (DDFS).

In a recent study, Haas, Bravo, and colleagues integrated optogenetic stimulation with simultaneous functional in vivo positron emission tomography (PET)/magnetic resonance imaging (MRI) measurements in rats. By activating the nigrostriatal pathway in the substantia nigra pars compacta (SNc), they observed concurrent metabolic and hemodynamic fluctuations associated with the dopaminergic pathway in living animals at the whole-brain level.
