"CNN-based Classification of I-123 ioflupane dopamine transporter SPECT brain images to support the diagnosis of Parkinson’s disease with Decision Confidence Estimation"- Aleksej Kucerenko
Autor: Aleksej Kucerenko, betreut von Prof. Dr. Christian Ledig and Dr. Ralph Buchert
Parkinson's disease (PD) is a prevalent neurodegenerative condition posing significant challenges to individuals and societies alike.
It is anticipated to become a growing burden on healthcare systems as populations age.
The differentiation between PD and secondary parkinsonian syndromes (PS) is crucial for effective treatment, yet it remains challenging,
particularly in cases of clinically uncertain parkinsonian syndromes (CUPS).
Dopamine transporter single-photon emission computed tomography (DAT-SPECT) is a widely used diagnostic tool for PD,
offering high accuracy but also presenting interpretational challenges, especially in borderline cases.
This study aims to develop reliable automated classification methods for DAT-SPECT images, particularly targeting inconclusive cases,
which may be misclassified by conventional approaches.
Convolutional neural networks (CNNs) are investigated as promising tools for this task.
The study proposes a novel performance metric, the area under balanced accuracy (AUC-bACC) over the percentage of inconclusive cases,
to compare the performance of CNN-based methods with benchmark approaches (SBR and Random Forest).
A key focus is the training label selection strategy, comparing majority vote training (MVT) with random label training (RLT),
which aims to expose the model to the uncertainty inherent in borderline cases.
The study evaluates the methods on internal and external testing datasets to assess generalizability and robustness.
The research was conducted in collaboration with the University Medical Center Hamburg-Eppendorf (UKE).
The dataset utilized for model training originated from clinical routine at the Department of Nuclear Medicine, UKE.
The attached figure showcases augmented versions for two sample cases from the dataset:
a healthy control case ('normal') and a Parkinson's disease case ('reduced') with reduced availability of DAT in the striatum.
The study addresses the need for reliable and automated classification of DAT-SPECT images,
providing insights into improving diagnostic accuracy,
reducing the burden of misclassifications and minimizing the manual inspection effort.

Benchmarking selected State-of-the-Art Baseline Neural Networks for 2D Biomedical Image Classification, Inspired by the MedMNIST v2 Framework"- Julius Brockmann
Autor: Julius Brockmann, betreut von Sebastian Dörrich
This thesis examines the benchmarking of state-of-the-art baseline neural networks in the field of 2D biomedical image classification. Focusing on the effectiveness of deep learning models on high-quality medical databases, the study employs pre-trained baseline networks to establish benchmarks. The research investigates four convolutional neural
networks and one transformer-based architecture, exploring how changes in image resolution affect performance. The findings highlight the advanced capabilities of newer convolutional networks and demonstrate the effectiveness of transformer architectures for handling large datasets. Common misclassifications and their causes are also briefly analyzed, offering insights into potential areas for improvement in future studies.
