研究目的:

本研究旨在开发一个新的深度学习框架,整合多种先进的医学影像计算方法用于假体周围感染(PJI)诊断,并生成PJI和无菌性衰竭(AF)的疾病概率图,然后可用于推导PJI和AF的潜在敏感性的放射学区域。  

Objectives of Study:

This study aims to develop a new deep learning framework that integrates multiple advanced medical image computational methods for periprosthesis infection (PJI) diagnosis and generates disease probability maps of PJI and aseptic failure (AF), which can then be used to derive radiological regions of potential sensitivity to PJI and AF.

纳入标准:

Inclusion criteria

排除标准:

1.急性假体周围感染(PJI,发生在距关节置换术后<3个月)或有急性血源性PJI;
2.在实验室或放射学评估前2周内接受了抗生素治疗;
3.其关节进行了任何再手术(如拆除假体并放置垫片);
4.临床诊断最终不明确。

Exclusion criteria:

1. Acute periprosthesis infection (PJI, <3 months after talar joint replacement) or acute hematogenous PJI;
2. Received antibiotic therapy within 2 weeks prior to laboratory or radiological evaluation;
3. Any resurgery of the joint (e.g. removal of prostheses and placement of spacers);
4. The clinical diagnosis is ultimately unclear.
