Exploratory study to assess feasibility of intracerebral hemorrhage detection by point of care cranial ultrasound
ConclusionsOur exploratory analysis yielded preliminary data on use of point of care cranial ultrasound for ICH diagnosis to inform imaging techniques, cranial topography on B mode and sample size estimation for future studies to evaluate sensitivity and specificity of cranial POCUS in adult patients. This pilot study is limited by small sample size and over representation of ICH in the study. Cranial POCUS is feasible using POCUS machines and may have potential as a screening tool if validated in adequately powered studies.

Stroke Mimics in the Acute Setting: Role of Multimodal CT Protocol ADULT BRAIN
CONCLUSIONS: Multimodal CT demonstrated low sensitivity but high specificity in the diagnosis of stroke mimics in the acute setting. The high specificity of multimodal CT allows ruling out stroke and thereby avoiding unnecessary revascularization treatment in patients with diagnosis of a stroke mimic.

Nationwide Patterns of Hemorrhagic Stroke among Patients Hospitalized with Brain Metastases: Influence of Primary Cancer Diagnosis and Anticoagulation
Brain metastases can contribute to a decreased quality of life for patients with cancer, often leading to malaise, neurologic dysfunction, or death. Intracerebral hemorrhage (ICH) is especially feared complication in patients with brain metastases given the potential for significant morbidity and mortality.

Diagnostic value of  alternative techniques to gadolinium-based contrast agents in MR neuroimaging—a comprehensive overview
AbstractGadolinium-based contrast agents (GBCAs) increase lesion detection and improve disease characterization for many cerebral pathologies investigated with MRI. These agents, introduced in the late 1980s, are in wide use today. However, some non-ionic linear GBCAs have been associated with the development of nephrogenic systemic fibrosis in patients with kidney failure. Gadolinium deposition has also been found in deep brain structures, although it is of unclear clinical relevance. Hence, new guidelines from the International Society for Magnetic Resonance in Medicine advocate cautious use of GBCA in clinical and resea...
