Cerebral Small Vessel Disease Burden in Patients with Transient Global Amnesia and its Relationship with Recurrence.

Objective: Cerebral Small Vessel Disease (CSVD) has not been systematically studied in patients with Transient Global Amnesia (TGA). We aimed to investigate the CSVD burden in patients with TGA and its relationship with TGA recurrence.

Methods: We retrospectively examined 69 patients diagnosed with TGA in a single center between January 2015 and November 2023.

Prevalence and Prognostic Factors of Cortical Laminar Necrosis in Acute Ischemic Stroke.

Background: Cortical laminar necrosis (CLN) is a specific type of cortical infarction, and little is known about its frequency and outcomes. We aimed to investigate the prevalence and outcomes of CLN caused by brain infarction and its prognostic factors.

Methods: This retrospective cohort study included patients with acute ischemic stroke (AIS) between 2019 and 2022 and for whom magnetic resonance images obtained at our center showed acute-stage CLN.

Multimodal magnetic resonance imaging analysis in the characteristics of Wilson's disease: A case report and literature review.

Wilson's disease (WD) is an inherited disorder of copper metabolism. Multimodal magnetic resonance imaging (MRI) has been reported to provide evidence of the extent and severity of brain lesions. However, there are few studies related to the diagnosis of WD with multimodal MRI.

Thin-Slice Magnetic Resonance Imaging-Based Radiomics Signature Predicts Chromosomal 1p/19q Co-deletion Status in Grade II and III Gliomas.

Chromosomal 1p/19q co-deletion is recognized as a diagnostic, prognostic, and predictive biomarker in lower grade glioma (LGG). This study aims to construct a radiomics signature to non-invasively predict the 1p/19q co-deletion status in LGG. Ninety-six patients with pathology-confirmed LGG were retrospectively included and randomly assigned into training ( = 78) and validation ( = 18) dataset.

White Matter Abnormalities of Auditory Neural Pathway in Sudden Sensorineural Hearing Loss Using Diffusion Spectrum Imaging: Different Findings From Tinnitus.

Sudden sensorineural hearing loss (SSNHL) is a complex and challenging emergency which requires evidence regarding its pathophysiological changes to guide the treatment. The aim of this study was to evaluate the white matter integrity of the auditory neural pathway in patients with unilateral SSNHL in acute stage by using diffusion spectrum imaging tractography. In the present study, 60 individuals with acute SSNHL (29 males, 50.

Conventional magnetic resonance imaging-based radiomic signature predicts telomerase reverse transcriptase promoter mutation status in grade II and III gliomas.

Purpose: Telomerase reverse transcriptase (TERT) promoter mutation status is an important biomarker for the precision diagnosis and prognosis prediction of lower grade glioma (LGG). This study aimed to construct a radiomic signature to noninvasively predict the TERT promoter status in LGGs.

Methods: Eighty-three local patients with pathology-confirmed LGG were retrospectively included as a training cohort, and 33 patients from The Cancer Imaging Archive (TCIA) were used as for independent validation.

Fusion Radiomics Features from Conventional MRI Predict MGMT Promoter Methylation Status in Lower Grade Gliomas.

Purpose: The methylation status of the O6-methylguanine-DNA methyltransferase (MGMT) promoter has been proven to be a prognostic and predictive biomarker for lower grade glioma (LGG). This study aims to build a radiomics model to preoperatively predict the MGMT promoter methylation status in LGG.

Method: 122 pathology-confirmed LGG patients were retrospectively reviewed, with 87 local patients as the training dataset, and 35 from The Cancer Imaging Archive as independent validation.

Pathophysiological Evaluation in a Case of Wernicke's Encephalopathy by Multimodal MRI.

To report a patient with Wernicke's encephalopathy (WE) using multimodal magnetic resonance imaging (MRI) including conventional MRI, diffusion-weighted MRI (DWI), arterial spin labeling (ASL), and proton MR spectroscopy (MRS). A 50-year-old woman of WE with a history of cholecystectomy and acute pancreatitis was given MRI scans including DWI, MRS, and ASL pre- and post-thiamine treatment. Two weeks after admission, the patient's condition rapidly improved.

ASL perfusion features and type of circle of Willis as imaging markers for cerebral hyperperfusion after carotid revascularization: a preliminary study.

Objectives: Cerebral hyperperfusion (CH) could be a disastrous outcome causing complication after carotid revascularization if not managed properly and timely. The aim of this study was to investigate the association between preoperative arterial spin labelling (ASL) perfusion features and circle of Willis (CoW) pattern with CH.

Methods: Forty-eight consecutive carotid stenosis patients who underwent carotid endarterectomy (CEA) or carotid artery stenting (CAS) were enrolled.

Crossed cerebellar diaschisis in post-treatment glioma patients: A comparative study of arterial spin labelling and dynamic susceptibility contrast.

Objectives: To assess crossed cerebellar diaschisis (CCD) in post-treatment glioma patients, and to compare the performance of arterial spin labelling (ASL) and dynamic susceptibility contrast (DSC) in detecting CCD.

Methods And Materials: This retrospective study included 130 patients who had both DSC and ASL. Among them, 16 had underwent fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography (F-FDG PET/CT).

Evaluation of recurrent high-grade gliomas treated with bevacizumab: A preliminary report of 3D pseudocontinuous artery spin labeling.

Purpose: To investigate the role of cerebral blood flow (CBF) derived from a 3D fast spin echo (FSE) pseudocontinuous artery spin labeling (pcASL) sequence in evaluating the survival rate of recurrent high-grade gliomas (rHGGs) that were treated with bevacizumab (BEV).

Materials And Methods: Sixteen patients with rHGGs who underwent 3T 3D FSE pcASL imaging 1-2 days before (baseline or pre-BEV) and within 1 month after BEV treatment initiation (post-BEV) were included in the study. Average (aCBF) and maximum (mCBF) cerebral blood flow of the enhancing tumor, their respective normalized values to contralateral normal-appearing white matter (rCBF_wm and mCBF_wm) and cerebellum (rCBF_cb and mCBF_cb), and the related changes between baseline and post-BEV were evaluated.
