Bone Lesion

The hypothesis of the study is that non-invasive Single photon emission computed tomography (SPECT-CT) bone scintigraphy makes it possible to better characterize solitary bone lesions, in particular the exclusion of their malignancy in order to avoid unnecessary biopsy and possible complications for the patient.

Brief Summary The purpose of this study is to determine if artificial intelligence (AI) can assist doctors in detecting broken bones, effusions, dislocations and bone lesions more quickly and accurately in an emergency room setting. The study will also evaluate whether AI can save time and reduce costs in healthcare. The main questions to be addressed are: * Does AI improve the accuracy of detecting broken bones/dislocations/effusions/bone lesions? * Can AI expedite the process of diagnosing broken bones/dislocations/effusions/bone lesions? * Does AI reduce healthcare costs by enhancing efficiency? To investigate these questions, two groups of patients will be compared. One group will follow the traditional diagnostic approach, while the other group will utilize AI to assist in diagnosing X-rays. Participants in the study will: Undergo standard X-ray imaging of injured arms or legs, as part of routine care. Have X-rays reviewed by doctors with or without AI support, depending on the assigned group. The study will include patients of all ages presenting to the emergency room with an isolated injury or joint complaints. No additional tests or treatments beyond standard care will be involved.

Using the novel FAPI probe 99mTc-HYNIC-FAPI-04 and quantitative SPECT/CT imaging technology, this study investigates the diagnostic efficacy of 99mTc-HYNIC-FAPI-04 quantitative SPECT/CT in patients with common solitary bone lesions in adults, and compares its diagnostic performance with conventional CT, MRI, and 99mTc-MDP bone scintigraphy. Follow-up pathological results of patients post-surgery were analysed to assess the accuracy of 99mTc-HYNIC-FAPI-04 diagnostic outcomes, and its diagnostic value and significance were evaluated.

The purpose of this study is to demonstrate the effect of bioceramic implants on the repair of human bone defects, and to explore the application of bioceramic materials in bone defects, bone implantation, and bone fusion. The surface microstructure of β-tricalcium phosphate bioceramic implants can be effectively controlled to guide the regeneration of bones, promote the restoration of bones, accelerate the speed of recovery, and improve bone quality, which is of great clinical and social significance.
