P14.04.A CHARACTERISTIC FEATURES OF PATIENTS WITH AUTOIMMUNE DIFFERENTIAL DIAGNOSES FOR PRIMARY CENTRAL NERVOUS SYSTEM LYMPHOMA (PCNSL)

Ingo Beyer, Anna Fischl, Isabel Wiesinger, Do Hoon Lee et autres

Abstract BACKGROUND The diagnosis of this rare subtype of B-cell non-Hodgkin’s lymphoma limited to the CNS includes magnetic resonance imaging (MRI), tissue biopsy, cerebrospinal fluid (CSF) analysis and systemic staging. In imaging, PCNSL may resemble a number of differential diagnoses including autoimmune …

MRI-defined patterns of infiltration and outcome in patients with glioblastoma

Katrin Scheu, Edith Vandieken, Katharina Hense, Katharina Rosengarth et autres

Abstract Background Glioblastoma is a rare primary tumor of the brain. Infiltration of glioblastoma into the brain parenchyma may influence prognosis. We therefore aimed to investigate possible influences of distinct patterns of MRI-defined infiltration on the prognosis. Methods We performed a retrospective …

Initial experiences with dynamic, quality indicator-based multimodal tissue analysis (M-Ref) with parallel assessment of viscosity and shear wave elastography in liver parenchyma alterations

Ernst Michael Jung, Isabel Wiesinger, Ulrich Kaiser, Friedrich Jung

BACKGROUND AND OBJECTIVE: Modern ultrasound technology enables detailed tissue morphology analysis. A novel approach involves measuring viscoelasticity or viscosity. This pilot study investigates the potential of a novel high-end ultrasound system with dynamic quality indicators and the M-Ref tool. METHODS: Using a …

Toward Foundation Models in Radiology? Quantitative Assessment of GPT-4V’s Multimodal and Multianatomic Region Capabilities

Quirin Strotzer, Felix Nieberle, Laura S. Kupke, Gerardo Napodano et autres

Background Large language models have already demonstrated potential in medical text processing. GPT-4V, a large vision-language model from OpenAI, has shown potential for medical imaging, yet a quantitative analysis is lacking. Purpose To quantitatively assess the performance of GPT-4V in interpreting radiologic …

P20.11.A DIAGNOSTIC DELAY OF PRIMARY CENTRAL NERVOUS SYSTEM LYMPHOMA (PCNSL) MAY BE CAUSED BY INFLAMMATORY DIFFERENTIAL DIAGNOSES

Ingo Beyer, Martin Proescholdt, Isabel Wiesinger, Elisabeth Bumes et autres

Abstract BACKGROUND PCNSL is a rare extranodal subtype of B-cell non-Hodgkin lymphoma initially located in the central nervous system. It can only be finally diagnosed with tissue sampling. Therefore, tumor biopsy and staging examinations beforehand can delay diagnosis. Consequently, PCNSL at histological …

Mild intracerebral bleeding does not adversely affect survival and neurological outcome of surgical therapy for left-sided infective endocarditis

Christian Schach, E Fuessl, Isabel Wiesinger, C. M. Wendl et autres

Abstract Background Intracerebral bleeding (IB) is a serious condition that requires increased attention and has implications for treatment options. For patients with infective endocarditis (IE), current guidelines recommend postponing surgery if IB is present. IB can be classified into four relevant groups …

Detection of virus-specific T cells via ELISpot corroborates early diagnosis in human Borna disease virus 1 (BoDV-1) encephalitis

Markus Bauswein, Bárbara Schmidt, André Gessner, Dennis Tappe et autres

BACKGROUND: Within endemic regions in southern and eastern Germany, Borna disease virus 1 (BoDV-1) causes rare zoonotic spill-over infections in humans, leading to encephalitis with a high case-fatality risk. So far, intra-vitam diagnosis has mainly been based on RT-qPCR from cerebrospinal fluid …

Multiparametric Sonographic Imaging of Thyroid Lesions: Chances of B-Mode, Elastography and CEUS in Relation to Preoperative Histopathology

Moritz Brandenstein, Isabel Wiesinger, Julian Künzel, Matthias Hornung et autres

BACKGROUND: The aim was to improve preoperative diagnostics of solid non-cystic thyroid lesions by using new high-performance multiparametric ultrasound examination techniques. METHODS: Multiparametric ultrasound consists of B-mode, shear-wave elastography and contrast enhanced ultrasound (CEUS) including Time-Intensity-Curve (TIC) analysis. A bolus of 1-2.4 …

Ultraschall bei COVID-19-Patienten

Ernst Michael Jung, Christian Stroszczynski, Isabel Wiesinger

Zusammenfassung Mit anhaltender Coronapandemie kommt dem Ultraschall als Real-Time-Bildgebung immer größere Bedeutung zu. Er ermöglicht u. a. eine frühe Diagnostik peripherer Lungenveränderungen. Eine nachfolgende mögliche Fibrosierung lässt sich mithilfe der Elastografie nachweisen, Mikroembolien und Infarkte lassen sich mithilfe der CEUS einschätzen. Bereits …
