Diagnostic accuracy of Magnetic Resonance Imaging (MRI) in Evaluation of Pituitary Adenoma
Abstract: Objectives: To assess the diagnostic accuracy of Magnetic Resonance Imaging in evaluation of pituitary adenoma. Methodology: This cross sectional observational study was done for a period of two years from July 2017 to June 2019 in the department of Radiology and Imaging, Dhaka Medical College Hospital (DMCH) with non-random purposive sampling of 36 patients suspected of having pituitary adenoma. Patients having no contraindication for MRI were imaged with 1.5 Tesla open MRI machine without and with contrast in the supine position with a slice thickness of 5-6 mm. Biopsy reports were compared with MR Diagnosis. The diagnostic value of MRI in the diagnosis of pituitary adenoma was determined by calculating sensitivity, specificity, accuracy, positive predictive value and negative predictive
