Especially, MUS is highly sensitive in detecting fasciculations in motor neuron diseases, and in revealing intensive care unit acquired weakness. Hereditary and inflammatory myopathies are associated with distinct patters of echo-intensity changes of affected muscles. Moreover, MUS can be used for guiding needle biopsy of muscle lesions, and for targeting intramuscular botulinum neurotoxin (BoNT) injection in neurological disorders with muscle hyperactivity. MUS-guidance of BoNT injection is especially recommendable in complex cervical dystonia, in task-related hand dystonia (writer’s cramp, musician dystonia), and in children and adolescents with cerebral palsy. Modern ultrasound technologies such as sono-elastography, tissue Doppler, and high-definition microvasculature imaging allow for novel diagnostic and therapeutic uses. Recently, an international expert group reported consensus guidelines for neuromuscular ultrasound training. The present review provides a concise overview of well-established diagnostic and therapeutic applications of MUS in clinical neurology, with specific focus at MUS for targeting intramuscular BoNT injections.","PeriodicalId":294068,"journal":{"name":"Journal of Neurosonology and Neuroimaging","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129153298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the causal relationship between SIH and CVT as a potential risk factor is not well understood. According to the Monro-Kellie principle, this is thought to be caused by compensatory expansion of the cerebral venous system, damage to the intravenous wall due to changes in cerebral buoyancy, or increased venous blood viscosity. Although anticoagulation therapy is typically the first choice of treatment for patients diagnosed with CVT, considering the potential risk of intracerebral hemorrhage in patients with CVT secondary to SIH is important. We report the case of a patient who developed CVT as a complication of SIH and discuss its mechanisms and treatment options. Early identification and appropriate treatment can lead to successful outcomes and the prevention of potential complications.","PeriodicalId":294068,"journal":{"name":"Journal of Neurosonology and Neuroimaging","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127120939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review summarizes the advantages and the specific roles of transcranial Doppler (TCD) ultrasonography for patients with acute and longterm effects of TBI. In critical care setting numerous publications showed that TCD is predictive of angiographic PTV and onset of ICH. The post TBI status of cerebrovascular reactivity and cerebral hemodynamics also has important implications with regard to the treatment of long-term effects of mild TBI (mTBI). Today it is abundant evidence that TCD is an important tool for monitoring the natural course of acute moderate and severe TBI, for evaluating the effect of medical treatment or intervention, for forecasting, and for identifying high-risk patients for onset of cerebral ischemia after TBI. TCD makes good clinical and economic sense as it is a reliable, quantitative, non-invasive and non-expensive “biomarker” to the acute clinical manifestations of TBI. TCD clinical utilization holds promise for better detection, characterization, and monitoring of objective cerebral hemodynamics changes in symptomatic patients with TBI not readily apparent by standard CT or conventional MRI techniques. TCD utilization will improve the sensitivity of neuroimaging to subtle brain perturbations and combining these objective measures with careful clinical characterization of patients may facilitate better understanding of the neural bases and treatment of the signs and symptoms of TBI. This review summarizes the advantages and the specific roles of TCD ultrasonography for patients with acute and long-term effects of TBI.","PeriodicalId":294068,"journal":{"name":"Journal of Neurosonology and Neuroimaging","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116754395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The initial postoperative results showed improved spasticity and motor function, but these gains plateaued and even receded, unlike other studies that noted progress at 10–18 months post-surgery. We hypothesized that the presence of C7 radiculopathy due to severe cervical foraminal stenosis may affect long-term outcomes after contralateral C7 transfer and serve as a contraindication for this surgery. These findings emphasize the importance of thoroughly assessing patients with cervical foraminal stenosis and the associated risk of radiculopathy before considering a contralateral C7 transfer. Further research is needed to assess the prevalence of cervical foraminal stenosis in patients undergoing contralateral C7 transfer and explore alternative surgical approaches or adjunctive treatments to optimize postoperative outcomes.","PeriodicalId":294068,"journal":{"name":"Journal of Neurosonology and Neuroimaging","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124895870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A paradigm shift from “time is brain” to a more precision medicine approach now called “imaging is brain”, has taken place during the last decade. This transformation has been fueled by the progress in neuroimaging. Advanced Neuroimaging incorporates perfusion imaging in order to depict real-time cerebral perfusion disturbances and provide maps of the penumbra and ischemic core that will inform individualized clinical decisions. Advance neuroimaging has now a fundamental role in triaging patients that will receive reperfusion treatments beyond the conventional time windows of 4.5 hours for intravenous thrombolysis and 6 hours for mechanical thrombectomy.

There were no specific findings in either brain imaging or cerebrospinal fluid. The severe headache persisted, accompanied by excessive sweating. As the cause was unclear, chest and abdomen computed tomography was taken, where an adrenal gland mass was confirmed. With a diagnosis of pheochromocytoma, the patient improved with treatment. This triad of symptoms (headache, sweating, and palpitations) should raise suspicion of pheochromocytoma; however, most patients do not present with all three symptoms. Because of this, if headaches persist without other neurological symptoms, further evaluation should be performed to determine other possible causes such as pheochromocytoma.","PeriodicalId":294068,"journal":{"name":"Journal of Neurosonology and Neuroimaging","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124577062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

No embolic source was detected from cardiac assessments.
