ABSTRACT

Objective: This is a cross-sectional and prospective study, which was conducted to compare accuracy between single pulse sequence MRI examination (limited MRI brain scanning) with the complete MRI brain scanning (consist of multiple pulse sequences). Material and Method: This is a prospective study of 100 patients and male to female ratio is 1.4:1 (fifty-nine males and forty-one females). Their ages ranged from 1 to 85yrs and maximum cases were in the age group 35 to 54yrs. Headache was the most common presenting complaint followed by hemiparesis and seizures. Result: There was 100% positive predictive value of “limited study” for hydro cephalus, brain edema, cerebral and cerebellar mass lesion, Age related atrophy and extracerebral mass.Positive predictive value of “limited study” is 92% for infarction, 75% for hemorrhage, 70% for ischemic lesion, 67% for pituitary mass. Limited study shows no positive predictive value for empty sella and cystic lesion. For white matter lesion, “limited study” shows 20% positive predictive value. Conclusion: Complete MRI study is comprehensive, reliable and accurate method of diagnosing different brain pathologies and anything less cannot takes its place. But considering the lesser time needed, lesser cost and convenience to patient as proved in this study the limited MRI brain study, which constitute only important sequences is clinically useful especially for brain screening. Key Words: MRI, LIMITED STUDY, BRAIN
