In glioma surgery, Protoporphyrin IX (PpIX) fluorescence may identify residual tumor that could be resected while minimizing damage to normal brain. We demonstrate that improved sensitivity for wide-field spectroscopic fluorescence imaging is achieved with minimal disruption to the neurosurgical workflow using an electron-multiplying charge-coupled device (EMCCD) relative to a state-of-the-art CMOS system. In phantom experiments the EMCCD system can detect at least two orders-of-magnitude lower PpIX.

- - Microfracture (MFX) is a technique used to repair cartilage by allowing cells from the bone to migrate into cartilage lesions, and this study explored how different awl shapes affect hole characteristics and marrow access in knee lesions.
- - The investigation involved 24 knee condyles from patients, where MFX was applied at two different depths (2 mm and 4 mm), and the resulting holes were analyzed with advanced imaging to assess their shape and size.
- - Findings indicated that the condition of the underlying bone (sclerosis level) impacts marrow access significantly, with severe sclerosis leading to reduced access and potentially causing bone issues instead of effective repair.
