Diagnosis of head masses involves clinical examination, neurological signs, and radiological imaging. MRI is the preferred imaging tool for detailed assessment of tumor, its extent and treatment plan. Objective: To find the level of concordance and discordance between radiology resident’s and consultant’s interpretation of MRI (Magnetic Resonance Imaging) done for brain masses. Methods: A cross sectional study was conducted at the radiology department of Rehman Medical Institute, Peshawar. Simple random sampling was done and sample size was calculated using kappa coefficients (Donner and Rotondi) n=100. 100 patients who visited department of Radiology over a period of two years were assessed by prospective analysis of their radiology reports. Senior resident’s and consultant’s reports were compared. All pre-op patients were included irrespective of age or gender. Data were collected and recorded on a specially designed proforma and entered into Microsoft excel and analyzed using SPSS (Version 22.0. IBM Corp., Armonk, NY). Results: MRI brain reports of 58 male and 42 female patients were evaluated. The most common tumors were gliomas, making up 52% of the total tumors. Metastasis being second most common tumor making 16%, meningiomas in 15%, pituitary tumors in 10% and vestibular schwannomas in 7% of the patients. Concordance, discordance, and Cohen’s Kappa values in different masses were gliomas. (Concordance=88.46%, Discordance=11.54%, k=0.336), Meningiomas (Concordance=86.66%, Discordance=13.34%, k=0.423), Metastasis (Concordance=81.25%, Discordance=18.75%, k=0.294), Pituitary Tumors (Concordance=80%) Discordance=20%, k=0.375) and Vestibular Schwannomas (Concordance=85.71%, Discordance= 14.29% k=0.588). Conclusions: There was no statistically significant difference between senior resident’s and consultant radiologist’s report of MRI brain masses.
