Thesis Abstract

Abstract
Brain tumors are a significant health concern worldwide, with various diagnostic imaging modalities utilized for their detection and characterization. This thesis presents a comparative analysis of Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) in the diagnosis of brain tumors. The study aims to assess the strengths and limitations of each imaging modality, evaluate their diagnostic accuracy, and explore the potential impact on patient management. The introduction provides a background of the study, highlighting the increasing prevalence of brain tumors and the importance of accurate and timely diagnosis. The problem statement emphasizes the need to compare CT and MRI to determine their respective roles in brain tumor diagnosis. The objectives of the study include evaluating the sensitivity, specificity, and overall diagnostic performance of CT and MRI in detecting brain tumors. The literature review encompasses ten key areas, including the principles of CT and MRI imaging, common types of brain tumors, imaging features of brain tumors on CT and MRI, and comparative studies assessing the diagnostic accuracy of these modalities. Additionally, the review explores advancements in imaging technology, such as functional MRI and diffusion-weighted imaging, and their role in enhancing diagnostic capabilities. The research methodology section outlines the study design, patient selection criteria, imaging protocols, and data analysis methods. It includes details on the retrospective analysis of imaging findings from patients with histologically confirmed brain tumors who underwent both CT and MRI examinations. The methodology also addresses potential biases and limitations inherent in retrospective studies. The discussion of findings delves into the comparative analysis of CT and MRI in diagnosing brain tumors, focusing on sensitivity, specificity, positive predictive value, negative predictive value, and overall diagnostic accuracy. The results highlight the strengths and weaknesses of each modality in detecting different types of brain tumors, including primary and metastatic lesions. The conclusion and summary chapter synthesize the key findings of the study, emphasizing the complementary roles of CT and MRI in brain tumor diagnosis. The study underscores the significance of multimodal imaging approaches and the importance of considering clinical factors when selecting the appropriate imaging modality for individual patients. In conclusion, this thesis provides valuable insights into the comparative analysis of CT and MRI in the diagnosis of brain tumors. The findings contribute to the existing literature on neuroimaging and offer practical implications for radiologists, clinicians, and researchers involved in the management of patients with brain tumors. Further research is warranted to explore emerging imaging technologies and optimize diagnostic algorithms for brain tumor evaluation.

Thesis Overview

The project titled "Comparative Analysis of Computed Tomography and Magnetic Resonance Imaging in the Diagnosis of Brain Tumors" aims to investigate and compare the effectiveness of two common imaging modalities, Computed Tomography (CT) and Magnetic Resonance Imaging (MRI), in the diagnosis of brain tumors. Brain tumors are abnormal growths of tissue in the brain that can be either benign or malignant, and accurate and timely diagnosis is crucial for treatment planning and patient outcomes. The research will begin with a comprehensive introduction that sets the stage for the study by outlining the importance of accurate imaging techniques in diagnosing brain tumors. The background of the study will provide a detailed overview of brain tumors, their prevalence, types, and the role of imaging modalities in their diagnosis. The problem statement will highlight the current challenges and limitations in using CT and MRI for brain tumor diagnosis, paving the way for the research objectives. The objectives of the study will focus on comparing the accuracy, sensitivity, specificity, and overall diagnostic performance of CT and MRI in detecting different types of brain tumors. The limitations of the study will acknowledge any constraints or challenges that may impact the research findings, such as sample size, data availability, or technological factors. The scope of the study will define the boundaries within which the research will be conducted, including the specific types of brain tumors and imaging parameters that will be considered. The significance of the study lies in its potential to improve diagnostic practices and patient outcomes in the field of neuroimaging. By comparing the strengths and weaknesses of CT and MRI in diagnosing brain tumors, the study aims to provide valuable insights that can guide clinicians in selecting the most appropriate imaging modality for each patient. The structure of the thesis will outline the organization of the research, including the chapters and sub-sections that will be covered. Chapter two will consist of a comprehensive literature review that synthesizes existing research on the use of CT and MRI in diagnosing brain tumors. This section will explore the advantages and limitations of each imaging modality, as well as any emerging trends or technologies that may impact their diagnostic accuracy. Chapter three will detail the research methodology, including the study design, data collection procedures, imaging protocols, and statistical analysis methods. This section will provide a transparent overview of how the data will be collected, analyzed, and interpreted to address the research objectives effectively. Chapter four will present the findings of the comparative analysis between CT and MRI in diagnosing brain tumors. This section will discuss the results in detail, highlighting any differences in diagnostic accuracy, sensitivity, specificity, and overall performance between the two imaging modalities. Finally, chapter five will offer a conclusion and summary of the research, including a discussion of the key findings, implications for clinical practice, recommendations for future research, and overall conclusions regarding the comparative analysis of CT and MRI in the diagnosis of brain tumors. The research overview aims to provide a clear and concise overview of the project, setting the stage for a detailed and thorough investigation into this critical area of medical imaging.
