Quantitative magnetic resonance imaging radiomics predicts photoreceptorness status in retinoblastoma

Christiaan M. de Bloeme, Robin Jansen, Ogul Uner, Khashayar Roohollahi et autres

BACKGROUND: Molecular characteristics of retinoblastoma cannot be assessed before treatment because tumor biopsy is contraindicated. Photoreceptorness reflects photoreceptor-related gene expression and tumor differentiation. Non-invasive imaging biomarkers that capture this biology are therefore needed. OBJECTIVE: To evaluate whether quantitative radiomics derived from pretreatment …

Follow-up of Cystic Pineal Glands in Retinoblastoma Patients Does Not Increase Detection of Pineal Trilateral Retinoblastoma

Christiaan M. de Bloeme, Robin W. Jansen, Joeka de Haan, Debbie Pieperjohanns et autres

PURPOSE: To evaluate the effectiveness of baseline screening and follow-up with magnetic resonance imaging (MRI) for detecting trilateral retinoblastoma (TRb) and assessing the risk of TRb development. DESIGN: Prospective multicenter cohort study. METHODS: A total of 607 retinoblastoma patients from 2012 through …

MR Imaging of Adverse Effects and Ocular Growth Decline after Selective Intra-Arterial Chemotherapy for Retinoblastoma

Christiaan M. de Bloeme, Sabien van Elst, Paolo Galluzzi, Robin W. Jansen et autres

This retrospective multicenter study examines therapy-induced orbital and ocular MRI findings in retinoblastoma patients following selective intra-arterial chemotherapy (SIAC) and quantifies the impact of SIAC on ocular and optic nerve growth. Patients were selected based on medical chart review, with inclusion criteria …

[Metachromatic leukodystrophy. Results of laboratory chemical, neurophysiologic, histologic and imaging procedures within the scope of a family study].

Julian Schröder, Joeka de Haan, M. Haupts

Examining the members of a family the validity of chemical analysis, neurophysiology and neuroimaging for the diagnosis of metachromatic leukodystrophy (MLD) is discussed. As the arylsulfatase A is not decreased in all cases, the neuroimaging (cranial computerized tomography--at a less extend magnetic …

MR imaging in multiple sclerosis: comparison with clinical, CSF, and visual evoked potential findings.

D Uhlenbrock, Dietmar Seidel, Walter Gehlen, H. Beyer et autres

MR examinations of 136 patients with multiple sclerosis (MS) were evaluated to correlate the results with clinical, CSF, and visual evoked potential (VEP) findings. In addition, 22 of the 136 patients were studied several times during a 5-month follow-up period. It was …

Magnetic resonance imaging of the normal female pelvis.

Gabriël Snoep, J M van Engelshoven, T. H. M. Falke, B. G. Ziedses des Plantes et autres

9 healthy volunteers were examined by magnetic resonance imaging in order to describe the anatomy of the normal female genital tract as seen by this technique. The visualization of the bony and pelvic skeleton and the muscles surrounding these structures is excellent. …
