Pseudoprogression is a diagnostic challenge in early posttreatment glioblastoma. We therefore developed and validated radiomics model using multiparametric MRI to differentiate pseudoprogression from tumor progression patients with glioblastoma.The was the enlarging contrast-enhancing portions of 61 glioblastomas within 3 months after standard treatment 6472 radiomic features being obtained contrast-enhanced T1-weighted imaging, fluid-attenuated inversion recovery apparent diffusion...
Multiple cranial neuropathies are complex neurological disorders that present significant treatment challenges due to their intricate and multifaceted underlying causes. Persistent trigeminal artery variant (PTAV) is an unusual anastomosis connects the internal carotid cerebellar artery, bypassing basilar artery. The incidence of PTAVs approximately 0.18% neurovascular compression rarely reported. Patients with schwannomatosis typically have multiple schwannomas without vestibular nerve...
Adult-onset Still's disease (AOSD) is a rare, systemic inflammatory disease. Neurological involvement in AOSD has rarely been reported. In this case report, we describe 44-year-old male patient with who presented seizures and scattered microhemorrhages on brain magnetic resonance imaging (MRI). We recommend MRI evaluation, including susceptibility-weighted (SWI), for patients exhibit neurological symptoms. A to the clinic strikingly high fever, sore throat myalgia that persisted 3 weeks. The...
In brain magnetic resonance imaging (MRI), white matter hyperintensity (WMH) is a commonly encountered finding and known to reflect cerebral small vessel disease. The aim of our study was investigate the association coronary artery calcium (CAC) with WMH elucidate relationship between atherosclerotic risk factors in large-scale healthy population. This retrospective included 1337 individuals who underwent MRI CAC scoring computed tomography at healthcare centers affiliated tertiary hospital....
Abstract This study aimed to evaluate the utility of an artificial intelligence (AI) algorithm in differentiating between cerebral cavernous malformation (CCM) and acute intraparenchymal hemorrhage (AIH) on brain computed tomography (CT). A retrospective, multireader, randomized was conducted validate performance AI AIH from CCM CT. CT images CM (< 3 cm) were identified database. Six blinded reviewers, including two neuroradiologists, radiology residents, emergency department physicians,...
Heat stroke is caused by losing control of one's body temperature. It can be life threatening without proper treatment. In this case report, we describe a heat patient treated with an external-cooling device, which commonly used for therapeutic hypothermia after cardiac arrest. A 67-year-old woman was found unconscious spontaneous breathing in sauna. Her temperature 40.5°C when she arrived at the emergency department, and diagnosed stroke. At seven hours applying Arctic Sun Temperature...
The angiographic spot sign (AS) on CT angiography (CTA) is known to be useful for predicting expansion in intracranial hemorrhage, but its use limited due relatively low sensitivity. Recently, dual-energy computed tomography (DECT) has been shown superior distinguishing between hemorrhage and iodine. This study aimed evaluate the diagnostic performance of hematoma (HE) using DECT AS traumatic hemorrhage.We recruited participants with confirmed via CTA suspected cerebrovascular injuries. We...
AIM This study aimed to investigate the survival and prognostic factors for anaplastic glioma, whether updated 2016 WHO classification had superior ability predict survival. MATERIALS AND METHODS Between January 2001 December 2013, 113 consecutive patients were diagnosed with glioma based on 2007 classification. We re-classified their diagnoses in accordance The Kaplan-Meier method, multivariate Cox proportional regression analysis, a time-dependent receiver operating characteristic curve...
<h3>BACKGROUND AND PURPOSE:</h3> Differences in molecular properties between one-molar and half-molar gadolinium-based contrast agents are thought to affect parameters obtained from dynamic contrast-enhanced imaging. The aim of our study was investigate differences nonionic gadobutrol ionic gadoterate meglumine patients with posttreatment glioma. <h3>MATERIALS METHODS:</h3> This prospective enrolled 32 who underwent 2 20-minute examinations, one meglumine. model-free parameter area under the...
Background Advanced imaging methods can enhance the identification of aneurysms infundibula, which reduce unnecessary follow-ups or further work-up, fear, and anxiety in patients. Purpose This study aimed to evaluate added diagnostic value three-dimensional proton density-weighted vessel wall magnetic resonance (3D-PD MRI) identifying from index lesions refer vascular bulging without vessels arising apex, observed using volume-rendered TOF-MRA circle-of-Willis compared with time-of-flight...
Abstract This study aimed to evaluate the utility of an artificial intelligence (AI) algorithm in differentiating between cerebral cavernous malformation (CCM) and acute intraparenchymal hemorrhage (AIH) on brain computed tomography (CT). A retrospective, multireader, randomized was conducted validate performance AI (SK Inc. C&C Medical Insight+ Brain Hemorrhage) AIH from CCM CT. CT images CM (< 3cm) were identified database. Six blinded reviewers, including two neuroradiologists,...
Objectives This study aimed to determine whether the olfactory bulb height (OBH) measured using magnetic resonance imaging (MRI) has clinical utility as an biomarker in evaluation of patients with idiopathic Parkinson’s disease (iPD) through its correlation movement impairment. Methods retrospective included cognitively intact suspected parkinsonism. All participants underwent T2-weighted measure OBH. Logistic regression was used OBH independent risk factor for distinguishing iPD from...
