This study aimed to distinguish two specific types of SG-LAIs at the gluteal muscle. Forty-seven patients [risperidone (RLAI): 28 patients, aripiprazole (ALAI): 19 patients] were examined using grayscale histogram analysis of echo-intensities. Pre- and immediately after (post)-injected SG-LAI region of interest (ROI) was placed on the same sites of gluteal muscle, and the grayscale histograms were recorded. Pre- and post-injected echogenicity values were analyzed using paired t -test, and Pearson’s moment correlation coefficient. Mixed effects model regression analysis was performed on variations in average echogenicity from age and medication type. Statistical significance was at 5%. There was no significant correlation between age and average echogenicity of ROI pre-intramuscular (IM) injection ( r = 0.26, p = 0.078). In both RLAI and ALAI, the mean echogenicity post-IM injection was significantly higher than pre-IM injection ( p < 0.001). With increasing age, the values of echogenicity of post-injection was decreased significantly ( p = 0.002). The increasing values of the echo-intensities post-injections of RLAI showed significantly higher than ALAI ( p = 0.002). It was considered that administered type of LAI could be identified because each LAI exhibits specific echographically findings, it also will be able to applied clinically.","PeriodicalId":40206,"journal":{"name":"Neurosonology and Cerebral Hemodynamics","volume":"38 1 1","pages":"7-12"},"PeriodicalIF":0.1,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77363172","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}

Subclinical small emboli, many of which might occur behind the overt embolization, will be detected as a microembolic signal (MES) with transcranial Doppler (TCD). Case report: A 54-year-old male with fever and impaired consciousness was admitted with suspected encephalopathy. His medical history included bioprosthetic aortic valve replacement performed 3 years before admission. Although IE was considered as differential diagnosis, transthoracic echocardiography and contrast-enhanced CT scan did not reveal the presence of lesions. According to the modified Duke criteria, his case was classified as “rejected IE.” However, TCD revealed four MESs in the left middle cerebral artery, and IE was reconsidered. Transesophageal echocardiography revealed a 14-mm mobile vegetation on the prosthetic valve. Although early surgery was planned, CT revealed small subarachnoid hemorrhages in the left cerebral hemisphere. The risk of systemic embolization was considered high; therefore, valve replacement was performed at day 6 after admission. After 1 month, the patient was discharged without sequelae. Conclusions: MESs may be useful as a marker for subclinical embolization in patients with IE. Further studies should assess the potential of TCD for the diagnosis and risk stratification of IE.","PeriodicalId":40206,"journal":{"name":"Neurosonology and Cerebral Hemodynamics","volume":"813 1","pages":"130-133"},"PeriodicalIF":0.1,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81622046","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}

In recent case reports, contrast-enhanced transoral carotid ultrasonography (CETOCU), which is essentially TOCU performed with perfluorobutane microbubbles as the ultrasonography contrast agent, produces clear intraluminal image of extracranial ICA, which is not possible with conven-tional carotid artery ultrasonography (CUS). Superb microvascular imaging (SMI) is a new Doppler imaging technique that employs a unique algorithm to minimize motion artifacts by eliminating clutter signals based on analysis of tissue movement. SMI significantly reduces motion artifacts and allows visualization of low-velocity blood flow in vessels. CUS with SMI and contrast enhanced carotid ultrasound are similar in images, and evalu-ate plaque neovascularization. We performed TOCU with SMI to two healthy persons, in order to examine simi-larity between CETOCU and TOCU with SMI. Although there were some inadequacies for small lesions, we found that TOCU with SMI can obtain images similar to CETOCU. TOCU with SMI is expected to be applied to clinical use.","PeriodicalId":40206,"journal":{"name":"Neurosonology and Cerebral Hemodynamics","volume":"13 1","pages":"13-17"},"PeriodicalIF":0.1,"publicationDate":"2018-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74594690","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}
