    Role of MRCP in Biliary Obstruction: Comparison with ERCP/Surgery in Addis Ababa, Ethiopia (2025)
    (Addis Ababa University, 2025) Habtamu Tilahun; Tesfaye Kebede; Assefa Getachew
    Background;-A fast growing noninvasive technique for Imaging assessing the hillary tree and pancreatic ducts is magnetic resonance cholangiopancreatography (MRCP). The effectiveness of MRCP to provide maximum intensity projection(MIP) images that closely resemble those produced by endoscopic retrograde cholagiopancetigraphy (ERCP) without the need for intravenous or oral contrast agents is one of its main advantages . It uses heavily T2 weighted imaging technique or sequences which result in the generation of bright signals from slow moving or static fluids like the bile fluid or secretion from the pancreas making these structures bright and the rest of the background will appear darker.(2) Objectives;-To evaluate the diagnostic performance of MRCP in patients suspected biliary obstruction by assessing imaging features , determining etiologic causes,and comparing its diagnostic accuracy with ERCP and surgical findings Methods;-A total of 112 patients from black lion hospital, lancet general hospital and MC comprehensive specialized hospital were included for this retrospective cross-sectional diagnostic accuracy study . There MRCP images were retrieved from PACs system and then interpreted by the body imaging subspecialist and fellow. Their surgical findings or ERCP findings were retrieved from the operational notes and their medical history were recovered from their hospital medical recording systems . Data was entered to epi info and then analysed with SPSS. Results;-MRCP demonstrated high diagnostic performance, with an overall accuracy of approximately 91.1%, sensitivity of 94.7%, and specificity of 72.2%. The most common cause of biliary obstruction was CBD stones contributing for 43.5 % of cases followed by benign strictures and of no etiology cases .MRCP showed excellent diagnostic performance for CBD stones, with sensitivity exceeding 90% and specificity around 94%. A notable finding in this study was that 16.1% of patients demonstrated biliary dilatation without an identifiable obstructing etiology. Conclusion and recommendation;-MRCP is a highly sensitive and accurate non-invasive imaging modality for evaluating biliary obstruction. It performs exceptionally well in detecting biliary dilatation and CBD stones and is highly reliable in excluding malignancy. However, limitations remain in detecting small stones and subtle lesions and in accurately characterizing strictures

    The Implementation of School Improvement Program in Government Secondary, Schools of Kirkossub-City, Addis Ababa
    (Addis Ababa University, 2025-11) Habtamu Tilahun; Zenebe Baraki
    The main purpose of this study was to assess the implementation of school improvement programsin government secondary schools. in order to fulfill the objectives, four fundamental research questions concerning the practices and effects of SIP in secondary schools were established. The research methodology utilized in this study was a mixed method design (QUAN+qual).Both primary and secondary sources of data were used. The primary sources of data were teachers, PTSA members, principals, and supervisors, the secondary sources of data were SIP related documents. Out of the total 261 distributed questionnaires of teachers, SIP and PTSA members 247 (94.6%) were properly filled out and returned. Interviews were conducted with 8 cluster supervisors and 16 principals. In addition, SIP related document was assessed. The information analyzed and interpreted by descriptive statistics (frequency, percentage, mean). The result of the study revealed that: (a) different activities in the four stage of SIP were implemented amoderate level; (b)perception of teachers and principal‟s towards the SIP was positive (c) stakeholders contribute to the implementation of SIP activities at moderate level and also the major factor that hinder to implement SIP i.e. due to complexity of the SIP there are some limitations to the school community havng the same understanding lack of awareness about SIP among the school community.Major condusion therefore, to alleviate this challenges, it is recommended that prepared frequently practical training for implementers and professional support, experience sharing program, conference about SIP from Addis Ababa Education office up to sub-city education office to overcome this problem.
