Presentation

The aim of my thesis is to evaluate the new CT technology (PCD-CT) in comparison to well-established, EID-CT and ICA.

Conventional energy integrated detector computed tomography (EID-CT) demonstrates high sensibility in detecting coronary artery stenosis and excellent negative predictive value. However, this method tends to overestimate CAD, leading to moderate specificity and positive predictive value. A recent advancement in CT technology is the photon counting detector computed tomography (PCD-CT). This innovation offers several technical benefits. Of particular relevance to this project are the potential implications for coronary artery diagnostics, including how the heightened spatial resolution and reduced blooming artifacts could enhance diagnosis.
When introducing a new clinical examination technique, it is imperative to determine if established scoring methods, such as the AS, remain reliable for early CAD detection and risk stratification.

Additionally, a comprehensive exploration of PCD-CT applications in coronary artery diagnostics is crucial for a thorough understanding. The primary interest and potential advantage of this project is that if the PCD-CT technique demonstrates a high positive predictive value, it could refine the diagnostic process and improve the selection of patients referred to invasive coronary angiography (ICA), ultimately reducing complications associated with invasive examinations and lowering costs.
