Multislice CT-guided evaluation of collagen-chitosan composite in promoting antebrachiocarpal arthrodesis in a rabbit model.

Background: Arthrodesis is a critical procedure for restoring stability and relieving pain in severely damaged joints. Successful bone fusion remains a significant challenge, often necessitating the use of biomaterials to enhance healing. Collagen and chitosan, two natural polymers with established biocompatibility and osteoconductive properties, have shown promise in regenerative medicine applications.

Inter-observer and intra-observer agreement of bone reporting and data system (Bone-RADS) in the interpretation of bone tumors on computed tomography.

Objective: To assess inter-observer & intra-observer agreement of the American College of Radiology (ACR) bone reporting and data system (Bone-RADS) in the interpretation of bone tumors on computed tomography (CT).

Methods: This retrospective study included 273 bone tumors 184 (67.4 %) benign and 89 (32.

Comparison of chest CT severity scoring systems for COVID-19.

Purpose: To compare the diagnostic performance and inter-observer agreement of five different CT chest severity scoring systems for COVID-19 to find the most precise one with the least interpretation time.

Methods And Materials: This retrospective study included 85 patients (54 male and 31 female) with PCR-confirmed COVID-19. They underwent CT to assess the severity of pulmonary involvement.
