“…CT has been a frequently applied modality for assessment of pectus excavatum ( Figure 1 ). The calculation of pectus indices (e.g., the Haller index and correction index) and identifying cardiac compression and displacement, chest asymmetry and sternal torsion are the main applications of CT. Current developments in preoperative evaluation through CT imaging focus on automatic quantification of pectus indices, minimizing radiation dose and surgical planning ( 11 - 29 ).…”

“…Surgeons may devise surgical strategies based upon CT-derived three-dimensional (3D) reconstruction of the thoracic wall ( 20 ). Other emerging techniques to aid in the decision process are 3D printing (additive manufacturing) of thoracic models and bar templates, or virtual simulations of the Nuss procedure ( 21 - 29 ). Preoperative planning using CT scans allows to create personalized pectus bars preoperatively for more effective corrections of the deformity and to eliminate intraoperative revisions of the bar shape.…”

Pectus excavatum, the most common pectus deformity, varies in severity and has been associated with cardiopulmonary impairment and psychological distress. Since its initial documentation, a multitude of imaging techniques for preoperative evaluation (i.e., diagnosis, severity classification, functional assessment, and surgical planning) have been reported. Conventional imaging techniques encompass computed tomography (CT), chest radiography, magnetic resonance imaging (MRI), echocardiography and medical photography, while three dimensional (3D) optical surface imaging is a promising emerging technique in the preoperative assessment of pectus excavatum. This narrative review explores the current insights and advancements of these imaging modalities. CT imaging allows for the calculation of pectus indices and evaluation of cardiac compression and displacement. Recent developments focus on automated calculations, minimizing radiation exposure and improving surgical planning. Chest radiography offers a radiation-reducing alternative for pectus index measurement, but is unsuitable for disproportionally asymmetric chest deformations. MRI is a radiation-free imaging method, and allows for the calculation of pectus indices as well as the assessment of cardiac function. Real-time MRI provides dynamic insights, while exercise MRI shows promise for comprehensive evaluation of cardiac function but requires additional developments. Using echocardiography, structural cardiac changes can be identified, but its use in evaluating cardiac function in pectus excavatum patients is limited. Medical photography combined with caliper measurements complements other imaging methods for qualitative and quantitative documentation of pectus excavatum. Emerging as an innovative technique, 3D optical surface imaging offers a rapid, radiation-free assessment of the deformity which correlates with conventional pectus indices. Potential applications include quantifying other morphological features and predicting cardiac compression. However, standardization and validation are needed for its widespread use. This review provides an overview of preoperative imaging of pectus excavatum, highlighting the current developments in conventional methods and the potential of the emerging 3D optical surface imaging technique. These advancements hold promise for the future of the assessment and surgical planning of pectus excavatum.

Automatic Performance Assessment in Three-dimensional Interactive Haptic Medical Simulators: A Systematic Review

2022

View full text Add to dashboard Cite

This study presents a literature systematic review of automatic performance assessment in three-dimensional interactive medical and dental simulators with haptic feedback, resulting in 63 included articles. The main contributions regard analysis and discussion of investigated procedures, extracted metrics, experiment types, and assessment techniques. Studies have mostly focused on assessing performance by analyzing metrics using statistical techniques, while machine learning algorithms appear to be underexplored. Metrics related to time were observed in 84% of the studies, and aspects related to force, error and precision were investigated to a lesser degree. Difficulties reported in the articles are discussed, and research opportunities are presented.
