A Cross Sectional Study to Evaluate the Sensitivity and Specificity of Magnetic Resonance Spectroscopy (MRS) in Diagnosing Intracranial Neoplastic Lesions

Diagnosing intracranial neoplastic lesions accurately are always challenging. Often neurosurgeons face difficulties getting appropriate tissue from appropriate site for biopsy. Histopathology is the most confirm tool for tissue diagnosis though contrast Magnetic Resonance Imaging (MRI) gives some clue about the nature of the lesion. This is a cross sectional descriptive study to evaluate the sensitivity and specificity of Magnetic Resonance Spectroscopy (MRS) in diagnosing intracranial neoplastic lesions. There were total 19 participants in this study. Study place was neurosurgery department of the Al Haramain hospital of Sylhet, Bangladesh. Average age of the participants was 62.3 years. Magnetic Resonance Spectroscopy (MRS) results were compared with the histopathology reports to find out the Sensitivity (85.71%), specificity (91.67%), positive likelihood ratio (10.29), negative likelihood ratio (0.16), positive predictive value (85.71%), negative predictive value (91.67%) and diagnostic accuracy (89.47%).
