We present a case of the T2-FLAIR mismatch sign in glioblastoma, isocitrate dehydrogenase (IDH)-wild type. The T2-FLAIR mismatch sign is known as a highly specific imaging finding of astrocytoma, IDH-mutant. Meanwhile, IDH-wildtype diffuse astrocytic gliomas with telomerase reverse transcriptase (...
The sensitivity and specificity of the mismatch sign for IDH-mut astrocytoma detection were 20% and 98.6%, respectively. There were no differences between patients with an IDH-mut astrocytoma with or without T2FLAIR mismatch sign when grouped according to this with related t...
However, many IDH-mutant astrocytoma has the potential to progress to grade 4 glioblastomas, leading to a less favorable prognosis. In a recent investigation, Shumpei Onishi et al. examined the T2-FLAIR mismatch sign as a possible imaging biomarker for assessing CDKN2A status in non-enhancing ...
The T2-Fluid-Attenuated Inversion Recovery (T2-FLAIR) mismatch sign is a radiogenomic marker that is easily discernible on preoperative conventional MR imaging. Application of strict criteria (adult population, cerebral hemisphere location, and classic imaging morphology) permits the non...
Introduction: Amide Proton Transfer Imaging(APT)is an MRI imaging method that images the increased concentration of amide groups in tumors and is expected to be clinically applied to the diagnostic imaging of gliomas.On the other hand,T2/FLAIR mismatch sign(T2/FLms)has been proposed as an MRI ...
Dynamic susceptibility contrast-MRI parameters, ADC values, and the T2-FLAIR mismatch sign are useful to differentiate between H3-mutant and H3-wild-type high-grade midline gliomaGlioblastomaPerfusion-weighted magnetic resonance imagingDiffusion magnetic resonance imaging...
Influence of T2 FLAIR Abnormalities in Survival Outcomes After Gross Total Resection of IDH Wildtype Glioblastomasdoi:10.1093/neuros/nyaa447_899INTRODUCTION. Survival benefits of supratotal resection for lower grade gliomas have been previously reported. However, little is known of the influence of ...

EP-1072: Comparison of T2 and FLAIR imaging for target delineation in glioblastomaPurpose: The objective of this study is to evaluate toxicity and cosmetic outcome in breast cancer patients treated with adjuvant hypo fractionated radiotherapy to the whole breast, and to identify the risk factors for...
