Chest computed tomography findings do not influence the decision of pneumologists regarding the diagnosis and management of pulmonary long coronavirus disease: a single center retrospective study Open
Chest CT did not influence the diagnostic decision of pneumologists for patients suspected to suffer from pulmonary long COVID. However, the confidence in the diagnosis was improved by chest CT. Still, based on our results chest CT does no…

Automatic segmentation of liver structures in multi-phase MRI using variants of nnU-Net and Swin UNETR Open
Accurate segmentation of the liver parenchyma, portal veins, hepatic veins, and lesions from MRI is important for hepatic disease monitoring and treatment. Multi-phase contrast enhanced imaging is superior in distinguishing hepatic structu…

Toward Foundation Models in Radiology? Quantitative Assessment of GPT-4V’s Multimodal and Multianatomic Region Capabilities Open
OpenAI’s GPT-4V reliably identified the imaging modality and anatomic region but could not safely detect, classify, or rule out abnormalities on single MRI, CT, and radiographic images.

Attenuation of the BOLD fMRI Signal and Changes in Functional Connectivity Affecting the Whole Brain in Presence of Brain Metastasis Open
To date, there are almost no investigations addressing functional connectivity (FC) in patients with brain metastases (BM). In this retrospective study, we investigate the influence of BM on hemodynamic brain signals derived from functiona…
