Evaluation of the Diagnostic Performance of Lung Ultrasound Compared to Chest X-rays for Diagnosis of Pneumonia in Children
… resistance. Addition of chest X-ray (CXR) to diagnostic algorithms improves specificity, but CXR use is limited by radiation exposure and relatively high costs, limiting access in low-resource settings. Current guidelines therefore reserve CXR for moderate to severe disease and hospitalised …

Retrospective review: diagnostic performance of PI-RADS V2.1 4 and 5 lesions in predicting clinically significant prostate cancer at Groote Schuur Hospital, South Africa
… against internationally recognized standards of performance. The PI-RADS lexicon should be a reliable predictor of significant prostate cancer to promote confidence in its continued use and to justify the expenditure on mpMRI prostate examinations in the diagnostic pathway of prostate cancer at …

Opportunities and challenges in oncology targeted drug development : an assessment of the use of prevalence and companion diagnostic performance thresholds to guide clinical trial strategies
… for both the drug and the required companion diagnostic. Tumor biology is also increasingly complex since recent studies suggest that there are limited numbers of individual driver mutations, complicated interactions throughout signaling pathways as well as extensive tumor heterogeneity, all …

Perceptually Relevant Measurements in Tomosynthesis Imaging
… these metrics relate to abnormality detection performance and diagnostic errors. The first part of this thesis evaluates the relevance of noise power spectrum (NPS) based metrics in characterizing the DBT images and their relation to human observer diagnosis performance. The NPS based power-law …

Machine Learning Algorithms for Improved Glaucoma Diagnosis
… visual function. Highly specific and sensitive diagnostic tests able to detect the clinically significant glaucomatous changes in the structure of the nerve fiber layer and visual field are therefore required for the early detection and management of this disease. This thesis treats the …

Functional Magnetic Resonance Imaging of Breast Cancer
… chemotherapy (NACT). This thesis compares the diagnostic performance of diffusion-weighted imaging (DWI) models in the breast using a systematic review and meta-analysis. Advanced diffusion models have been proposed that may improve the performance of standard DWI using the apparent diffusion …

Panoramic Radiographic Diagnosis of Molar-Incisor Hypomineralization in Permanent Dentition
Purpose: To evaluate the diagnostic potential of panoramic radiographs for identifying Molar–Incisor Hypomineralization (MIH) in the permanent dentition of children and to compare the diagnostic performance of pediatric dental specialists with that of other dental professionals. Methods: This …

The Impact of Instrumentation Location and Reliability on the Performance of Operators Using an Ecological Interface for Process Control
… evaluation suggested that steady-state control performance of operators was not negatively impacted by sensor failures when using an EID interface or the conventional mimic display. Furthermore, displaying higher-order information appeared to support general diagnostic performance when dedicated …

Predictive model to estimate ionized calcium from routine serum biochemical profiles in dogs
… serum biochemical values and (2) compare the diagnostic performance of predicted ionized calcium (piCa) to those of total calcium (tCa) and two corrected tCa formulae; and (3) study the relationship between biochemical values and variation of measured ionized calcium (miCa). This was a …

Self-Supervised ECG Learning for Multimodal Clinical Tasks
… time series, images, and text to support robust diagnostic reasoning across diverse input combinations. We first introduce ECG-JEPA, a self-supervised encoder pretrained on multiple ECG datasets to learn generalizable time series representations. This unimodal pretraining improves ECG …

The Advantage of Digital Tomosynthesis for Pulmonary Nodule Detection concerning Influence of Nodule Location and Size: Phantom Study
… (JAFROC) was used to analyze overall diagnostic performance for each modality. The lesion localization fraction (LLF) and non-lesion localization fraction (NLF) were determined and compared among three modalities classified by size and location of nodule. Result: JAFROC analyses …

Performance of host blood transcriptomic signatures for TB diagnosis and monitoring TB treatment
Non-sputum-based diagnostic tests are necessary to enable tuberculosis (TB) diagnosis and monitoring of TB treatment. This work aimed to identify which published blood transcriptomic TB signatures have the best diagnostic performance to distinguish between TB cases and other respiratory diseases …
