MAGNETIC RESONANCE IMAGING IN THE DIAGNOSIS AND CLINICAL EVALUATION OF BRAIN TUMORS: A STUDY BASED IN UZBEKISTAN

Аннотация

Abstract: Brain tumors present complex diagnostic and therapeutic challenges, necessitating an integrated approach that combines clinical expertise with advanced neuroimaging techniques. Magnetic Resonance Imaging (MRI) has emerged as a cornerstone modality for the evaluation of intracranial neoplasms, offering non-invasive, high-resolution visualization of brain structures. This study, conducted at the Republican Specialized Neurosurgery Scientific and Practical Medical Center in Tashkent, Uzbekistan, aimed to evaluate the diagnostic accuracy of MRI, with a focus on advanced imaging modalities such as Dynamic Contrast-Enhanced MRI (DCE-MRI) and Diffusion-Weighted Imaging (DWI), in differentiating benign from malignant brain lesions. Over a one-year period (2023–2024), MRI scans of 129 patients were reviewed. Results demonstrated high sensitivity (92%) and specificity (86%) for malignant tumor detection. Enhanced diagnostic precision was achieved through DCE-MRI and DWI, which improved tissue characterization by assessing perfusion dynamics and cellular density. These findings support the vital role of MRI in early detection, treatment planning, and prognosis evaluation in neuro-oncology.
