An Interpretable Approach to Automated Severity Scoring in Pelvic Trauma

چکیده
Pelvic ring disruptions result from blunt injury mechanisms and are often found in patients with multi-system trauma. To grade pelvic fracture severity trauma victims based on whole-body CT, the Tile AO/OTA classification is frequently used. Due to high volume of CTs generated busy centers, an automated approach would provide substantial value, e. g., prioritize reading queue attending radiologist. In such scenario, method should perform grading a transparent process interpretable features enable interaction human readers lower their workload by offering insights first read scan. This paper introduces yet decision support system assist radiologists detection classification. The operates similarly interpretation CT scans detects distinct fractures specificity using Faster-RCNN model that then interpreted structural causal clinical best practices infer initial grade. Bayesian finally, object detector queried for likely co-occurring may have been rejected initially due highly specific operating point detector, resulting updated list detected corresponding final Our it provides finding location type as well information important counterfactuals invalidate system’s recommendation achieves AUC 83.3%/85.1% translational/rotational instability. Despite being designed human-machine teaming, our does not compromise performance compared previous black-box approaches.

A Neural Approach to Automated Essay Scoring
Traditional automated essay scoring systems rely on carefully designed features to evaluate and score essays. The performance of such systems is tightly bound to the quality of the underlying features. However, it is laborious to manually design the most informative features for such a system. In this paper, we develop an approach based on recurrent neural networks to learn the relation between...
متن کاملScoring systems of severity in patients with multiple trauma.
Trauma is a major cause of morbidity and mortality; hence severity scales are important adjuncts to trauma care in order to characterize the nature and extent of injury. Trauma scoring models can assist with triage and help in evaluation and prediction of prognosis in order to organise and improve trauma systems. Given the wide variety of scoring instruments available to assess the injured pati...

Although the operational scoring of the TOEFL iBT speaking section features the overall judgment of an examinee's speaking ability, the evaluation of specific components of speech such as delivery (pace and clarity of speech) and language use (vocabulary and grammar use) may be a promising approach to providing diagnostic information to learners. This study used an evidence-centered design appr...
متن کاملPelvic Trauma
Patients with traumatic pelvic ring injury may represent an immense challenge for the emergency physician. First, patients with pelvic ring fractures are at risk for exsanguinating pelvic hemorrhage. Furthermore, the profound magnitude of force required to disrupt the pelvic ring frequently causes severe injuries to other organ systems. The resuscitation from hemorrhagic shock, rapid identifica...
