This disorder includes both HV and IVC obstructions and hepatopathy. This study aimed to conduct a systematic review of the survival rate and clinical success of different types of endovascular treatments for Budd-Chiari syndrome (BCS). All participant studies were retrieved from four databases and selected according to the eligibility criteria for systematic review of patients with BCS. The survival rate, clinical success of endovascular treatments in BCS, and survival rates at 1 and 5 years of publication year were calculated accordingly. A total of 3398 patients underwent an endovascular operation; among them, 93.6% showed clinical improvement after initial endovascular treatment. The median clinical success rates for recanalization, transjugular intrahepatic portosystemic shunt (TIPS), and combined procedures were 51%, 17.50%, and 52.50%, respectively. The median survival rates at 1 and 5 years were 51% and 51% for recanalization, 17.50% and 16% for TIPS, and 52.50% and 49.50% for combined treatment, respectively. Based on the year of publication, the median survival rates at 1 and 5 years were 23.50% and 22.50% before 2000, 41% and 41% in 2000‒2005, 35% and 35% in 2006‒2010, 51% and 48.50% in 2010‒2015, and 56% and 55.50% after 2015, respectively. Our findings indicate that the median survival rate at 1 and 5 years of recanalization treatment is higher than that of TIPS treatment, and recanalization provides better clinical improvement. The publication year findings strongly suggest progressive improvements in interventional endovascular therapy for BCS. Thus, interventional therapy restoring the physiologic hepatic venous outflow of the liver can be considered as the treatment of choice for patients with BCS which is a physiological modification procedure.</p>","PeriodicalId":15512,"journal":{"name":"Journal of Clinical Imaging Science","volume":"13 ","pages":"5"},"PeriodicalIF":0.9,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/dc/0d/JCIS-13-5.PMC9899460.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9243997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assesses the efficacy of this approach in Yttrium-90 labeled microspheres radioembolization. To compare transradial to transfemoral access in hepatocellular carcinoma patients who underwent Yttrium-90 radioembolization. MATERIALS AND METHODS A total of 244 hepatocellular carcinoma patients underwent 337 radioembolization procedures at our institute from May 2014 to May 2020. The transradial access-group included 188 patients (252 procedures) while the transfemoral access group had 63 patients (85 procedures). The recovery time, fluoroscopy time, contrast volume, peak radiation dose, and equipment cost for each procedure were all reviewed to evaluate for statistical differences between the two groups. RESULTS The transradial cohort recorded a significantly shorter (P < 0.01) mean recovery time (from the end of the procedure to discharge) and had a significantly shorter (P < 0.05) use of contrast volume versus the transfemoral group. In addition, the radiation dose and fluoroscopy time were lower in the transradial subset, although not statistically different. Furthermore, the overall cost for procedural equipment was significantly less (P < 0.01) in the transradial cohort than in the transfemoral. No major complications were reported in the transradial group, while one pseudoaneurysm was noted in the transfemoral group. CONCLUSION With respect to many pertinent parameters, transradial access was evaluated as being more advantageous than transfemoral access. The results of this study suggest that transradial access should be considered more often, whenever feasible, as an option in the Yttrium-90 treatment of hepatocellular carcinoma patients.","PeriodicalId":15512,"journal":{"name":"Journal of Clinical Imaging Science","volume":"168 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75978757","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}

Various subtypes of intracerebral hamartomas, associated with seizure disorders, have been described. In this report, we describe a subtype of intracerebral hamartoma associated with intractable epilepsy in a 10-year-old patient. Initial MR imaging demonstrated a mildly expansile, T2/FLAIR hyperintense, T1 isointense, nonenhancing lesion with blurring of the gray-white junction in the left amygdala. Surgical resection was performed, and pathology confirmed oligodendroglial hamartoma. Patient’s seizures recurred after a two-year interval with imaging demonstrating a similar lesion in the right amygdala which in retrospect was also seen on multiple imaging studies. This case report demonstrates the importance of recognizing oligodendroglial hamartomas as a cause of intractable seizures given the imaging findings, distinguishing it from ganglioglioma, dysembryoplastic neuroepithelial tumor, and oligodendroglioma, and the importance of closely looking/searching for contralateral lesions, which has important therapeutic and prognostic implications.","PeriodicalId":15512,"journal":{"name":"Journal of Clinical Imaging Science","volume":"106 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79123650","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}

Sexual dimorphism of left and right mandibular ramus parts (sigmoid notch bordered by coronoid and condylar process). The shape of coronoid process, condyle, and sigmoid notch were interpreted. Results The most prevalent shape of sigmoid notch was wide variant (41.2%), condyle was convex type (50%) and coronoid was round (53.4%). Condyle and coronoid showed asymmetry between right and left with p-value 0.001 and 0.019, respectively. This study has illustrated that triangular-shaped coronoid was more in females (p-value 0.012). Conclusion Sexual dimorphism is observed in the shape of the mandible due to masticatory activity at the point of insertion of temporalis muscle, biting force, hormones, and various genetic reasons. The results have exemplified that the morphometric variation of condyle, coronoid and sigmoid notch can be used as a tool for personal identification.","PeriodicalId":15512,"journal":{"name":"Journal of Clinical Imaging Science","volume":"47 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78848716","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}

Among them, four (16.7%) demonstrated nivolumab-induced thyroid dysfunction that shows either hypothyroidism or hyperthyroidism. Three and one cases were treated with nivolumab for lung cancer and renal cell carcinoma, respectively. Two patients with hypothyroidism (cases 1 and 2) showed reduced thyroid volume (volume change ratio: 0.80 and 0.84) on computed tomography (CT) images. Besides, remarkably diminished CT attenuation of the thyroid gland was observed in a patient with hypothyroidism (case 2). One of the two patients with hyperthyroidism showed increased thyroid volume (volume change ratio: 1.32) (case 3), whereas no difference in the thyroid gland volume was observed between the previous and follow-up CT in another patient with hyperthyroidism (case 4). Thyroid volume change ratio >0.1 was observed even in 6 of 20 (30%) patients without thyroid dysfunction. Considering the wide use of nivolumab in cancer treatment, radiologists should be aware that changes in the thyroid volume and attenuation on CT are associated with thyroid dysfunction caused by nivolumab, as well as thyroid volume may change even in patients with normal thyroid function during nivolumab therapy.","PeriodicalId":15512,"journal":{"name":"Journal of Clinical Imaging Science","volume":"14 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2022-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82900807","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}
