It uses semiconductor materials such as cadmium telluride, cadmium zinc telluride, and silicon to directly count x-ray photons while resolving their energy levels. This energy-resolving capability ensures equal weighting of low- and high-energy photons, eliminates electronic noise, and enables material-specific imaging. The absence of physical septa in the detector-used in EIDs to prevent light photon cross-talk-results in smaller effective detector pixels in PCD-CT, enhancing detection efficiency and spatial resolution. These innovations collectively enhance diagnostic accuracy while enabling significant radiation dose reduction. This paper provides a comprehensive overview of PCD-CT technology, comparing it with EID-based systems. It highlights key advantages such as superior spatial and contrast resolution, spectral imaging, and noise reduction. Additionally, the review discusses PCD-CT's radiation dose reduction across cardiovascular, thoracic, abdominal, musculoskeletal, neuroimaging, and pediatric applications. Despite its promise, PCD-CT faces challenges, including non-ideal detector performance, increased electronic complexity, and calibration requirements to maintain accuracy.

Lining the inner surface of vessels, the endothelium acts as a barrier that normally prevents the passage of cells from the bloodstream into tissues and promotes the recruitment of immune cells during stressful, injured or infected conditions. Profound changes in endothelial function occur in response to irradiation, determining the tumour response to radiotherapy and participating in the initiation and development of adverse effects. In both normal tissues and tumours, radiation makes endothelial cells more adhesive to circulating cells, stimulates transendothelial migration and promotes immune infiltration, possibly chronic and harmful to normal tissues. Considering the active role of endothelium in immune cell recruitment, targeting endothelial cells becomes an attractive strategy to improve the therapeutic gain of radiotherapy. To this end, it is crucial to better understand how endothelial cells respond to irradiation in vivo and to determine their role in regulating immune cell recruitment. Advanced analytical technologies, such as single-cell RNA sequencing and spatial transcriptomics, now enable to uncover the molecular responses of cells in living organisms and comprehend their interactions within an organ.
