Comparison Of Susceptibility Weighted Imaging In Closed Head Injury To Conventional MRI

Abstract

Introduction: Head injuries are fast becoming a major cause of morbidity and mortality worldwide. 
Susceptibility Weighted Imaging (SWI) is a new T2 weighted Gradient Echo technique is more 
sensitive than CT scan and conventional T1W and T2W weighted images of MRI. Aims and 
objectives: To compare the role of conventional MR imaging with SWI in detection and 
characterisation of diffuse axonal injuries (DAI) in closed head trauma. Material and methods: 20 
patients of acute closed head injury with suspected DAI referred to the Department of 
Radiodiagnosis were taken up for MR imaging. Conventional MRI techniques was compared with 
SWI using students paired T test. Results: Majority of the patients were young males in the age 
group of 21 to 40 years. SWI was the most sensitive MR sequence for detection of shear lesions 
followed by DWI, FLAIR, T2W and T1W.
