Background/Introduction Stents cause blooming artifacts and artificial-lumen-narrowing (ALN) in CT-angiography. ALN and contrast-to-noise-ratio (CNR) are influenced by tube-voltage and reconstruction parameters, which may interact. Objective/Purpose To determine the optimal combination of tube-voltage and reconstruction parameters and their relative impact on objective image …

BACKGROUND AND OBJECTIVES: Cardiac abnormalities are among the most common and complex risk factors of pediatric acute ischemic stroke (AIS). Although endovascular treatment (EVT) is increasingly used in children, uncertainty persists regarding its safety and effectiveness in patients with underlying cardiac disease, …

BACKGROUND AND OBJECTIVES: Recent randomized trials reported no overall functional benefit of endovascular treatment (EVT) for distal medium-vessel occlusion (DMVO) and did not identify consistent effect modifiers to guide patient selection. Consequently, the role of EVT-particularly for M2 occlusions-remains controversial. We investigated …

Objective: The insertion of venous catheters into supra-aortic vessels is a standard procedure in the treatment of a large number of diseases. Incorrect placement of venous catheters into and accidental perforation of arterial vessels is a rare but serious complication that can …

BACKGROUND AND OBJECTIVES: Recent trials have shown the efficacy of endovascular thrombectomy (EVT) in patients with acute ischemic stroke due to large vessel occlusion (AIS-LVO) and large infarcts on admission. However, many patients still experience poor outcomes despite treatment. The aim of …

INTRODUCTION: Perimesencephalic subarachnoid hemorrhage (pmSAH) is a rare, typically benign subtype of non-aneurysmal subarachnoid hemorrhage (SAH). While the majority of patients demonstrate a positive recovery trajectory, a subset of patients experiences complications, including vasospasm, hydrocephalus, or delayed cerebral ischemia (DCI). Reliable imaging …

Background/Objectives: Perimesencephalic subarachnoid hemorrhage (pmSAH) is generally considered to be a benign variant of spontaneous SAH. However, in rare cases, an underlying aneurysm may be present, altering both clinical management and prognosis. The aim of this study was to evaluate the prognostic …

ABSTRACT BACKGROUND: There is currently no consensus on the most appropriate emergent treatment for patients with acute ischemic stroke secondary to large vessel occlusion (AIS-LVO) and minor stroke. These patients were excluded from prior randomized controlled trials assessing the efficacy of mechanical …

Objective: The benign nature of perimesencephalic subarachnoid hemorrhage (pmSAH) can be challenged by the occurrence of complications. Given the limited prognostic value of established clinical parameters for the development of complications in patients with pmSAH, this study evaluates the potential of volumetric …

PURPOSE: Lower-grade gliomas typically exhibit 5-aminolevulinic acid (5-ALA)-induced fluorescence in only 20-30% of cases, a rate that can be increased by doubling the administered dose of 5-ALA. Fluorescence can depict anaplastic foci, which can be precisely sampled to avoid undergrading. We aimed …
