摘要

背景:星形细胞瘤的准确检测是非常困难的。目的:探讨磁共振成像(MRI)在颅内星形细胞瘤诊断中的应用价值。方法:这项横断面研究于2013年1月至2013年12月在达卡萨利马拉爵士医学院(SSMC & MH)放射学和影像学与神经外科和病理学系合作进行,为期一年。本研究开始前,研究方案经SSMC伦理委员会(当地伦理委员会)批准。所有临床诊断为颅内星形细胞瘤并在门诊和门诊就诊的患者均被纳入研究人群。抽样方法为有目的、非随机抽样。所有病例均行MRI检查。术后切除组织在各自科室进行组织病理学检查。然后将收集到的报告与MRI结果进行比较。结果:本研究样本量为48例星形细胞瘤患者。MRI诊断星形细胞瘤的敏感性、特异性、阳性预测值、阴性预测值和准确性分别为92.0%、80.0%、96.0%、67.0%和90.3%。结论:MRI对星形细胞瘤有较高的诊断有效性。孟加拉国国家神经科学研究所杂志,2022年7月;8(2):202-205

Astrocytoma Detection with Magnetic Resonance Imaging among Patients attended at a Tertiary Care Hospital in Dhaka City
Background: Accurate detection of astrocytomas is very difficult. Objective: The purpose of the present study was to evaluate the usefulness of Magnetic Resonance Imaging (MRI) in detection of intracranial astrocytoma. Methodology: This cross sectional study was carried out in the Department of Radiology and Imaging with the collaboration of Department of Neurosurgery and Department of Pathology at Sir Salimullah Medical College (SSMC & MH), Dhaka from January 2013 to December 2013 for a period of one (1) year. Prior to the commencement of this study, the research protocol was approved by the ethical committee (Local Ethical committee) of SSMC. All the patients presented with clinically diagnosed cases of intracranial astrocytoma who were attended in the OPD and IPD were included as study population. The sampling technique was purposive, non-random sampling method. MRI was performed in all cases. The postoperative resected tissues were examined histopathological in the respective department. Then the collected reports were compared with findings of MRI. Results: The sample size of the present study was 48 astrocytoma patients. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of MRI for the diagnosis of astrocytoma are 92.0%, 80.0%, 96.0%, 67.0% and 90.3% respectively. Conclusion: In conclusion MRI has a high diagnostic validity for the detection of astrocytoma. Journal of National Institute of Neurosciences Bangladesh, July 2022;8(2):202-205
