Diffusion-weighted MRI for differentiating Wilms tumor from neuroblastoma

Diffusion-weighted MRI for differentiating Wilms tumor from neuroblastoma.

PURPOSE Wilms tumor (WT) and neuroblastoma (NB) are the most common pediatric abdominal malignant neoplasms of the kidney and adrenal gland. Differentiating them from each other is essential since their treatments are different. Here, we aimed to show the diffusion characteristics of WT and NB for differentiation. METHODS Diffusion-weighted imaging (DWI) of 17 histopathologically diagnosed le...

Diffusion-weighted MRI for differentiating Creutzfeldt-Jacob disease mimics.

Sporadic Creutzfeldt-Jacob disease (CJD) is a rare neurodegenerative, prion disease characterized by rapidly progressive dementia, visual disturbances, myoclonus and extrapyramidal and pyramidal involvement. An 80-year-old woman presented with progressive dementia and visual and auditory hallucinations over a two-month period. Neurological examination revealed cognitive impairment and right hem...

Autoantibody Signature Differentiates Wilms Tumor Patients from Neuroblastoma Patients

Several studies report autoantibody signatures in cancer. The majority of these studies analyzed adult tumors and compared the seroreactivity pattern of tumor patients with the pattern in healthy controls. Here, we compared the autoimmune response in patients with neuroblastoma and patients with Wilms tumor representing two different childhood tumors. We were able to differentiate untreated neu...

Differentiating Benign from Malignant Sinonasal Lesions: Feasibility of Diffusion Weighted MRI

Introduction  Appearance of nasal masses on routine CT and MRI are not pathognomonic. We utilized the apparent diffusion coefficient (ADC) value obtained from diffusion weighted image (DWI) to detect the differences in the microstructures of tumor and non-tumor tissues. Objective  The objective of our study was to evaluate the diagnostic role of DWI and ADC values in differentiating between mal...
