Master student for AI-driven image analysis of RENAL score

Automating the R.E.N.A.L. score in patients with a renal cell carcinoma
This application has been filled. Please see our page for open vacancies.
Renal cell carcinoma (RCC) is the most common form of kidney cancer in adults. Treatment for RCC often involves surgery, either by removing the entire kidney (total nephrectomy) or preserving part of the kidney while removing the tumor (nephron sparing surgery). The choice of surgery is dependent on multiple factors like patient overall health and experience of the treating surgeon, but the main factor is the anatomical complexity of the tumor. To assist surgical decision-making, the RENAL score was introduced [1] as a radiological tool to quantify tumor complexity. The RENAL score consists of 5 different components, all focused on different aspects of the tumor (anatomy).
Although the RENAL scoring system has been suggested in literature to be useful in surgical planning, the clinical use is limited, mainly because of the time investment of radiologists to obtain all components of the RENAL score and the inter-observer variability between observers. Several efforts have been made to automate the RENAL score, but these methods rely on simplification of the anatomical situation or other heuristics [2], [3].
Recent advances in deep learning for medical image analysis now enable the automation of complex anatomical assessments directly from CT scans. At our research group, we develop a suite of AI models that automatically segment relevant structures (e.g., tumors, kidneys, collecting system) and compute features required for the RENAL scoring system. These models, covering all components of the RENAL score, will be available at the start of the project. They provide a strong foundation for further development, refinement, and validation of a more nuanced, continuous, and interpretable version of the RENAL score.
Objectives / Aims / Goals
: Develop and evaluate an enhanced version of the RENAL scoring system using AI-driven image analysis.
(depending on project scope, student interests, literature findings, and initial conclusions):
Automate and compare the RENAL scoring system to other scoring systems (e.g., C-score or PADUA)
Add explainability to the scoring system (for example by visualizing the different distance based measures).
