TO ANALYZE THE SENSITIVITY OF DIFFUSION WEIGHTED IMAGING (AT HIGHER B VALUE, IN DIFFERENT IMAGING PLANES AND COMPARISON WITH ADC, FLAIR, T2W IMAGING).

Abstract

Background- The danger of intracranial pathology is that expansion in an enclosed space leads to brain compression causing ischemia, swelling and loss of function that can be permanent and possibly fatal.

Methods- This was a simple observational prospective study carried out at the Department Of Radio-Diagnosis and Modern Imaging, S.P.M.C. & A.G. Of P.B.M. Hospitals, Bikaner. All the patients presented for MR brain study with some neurological complaints and showed positive findings on MRI were included in this study.

Results-Mean ADC value in different type of  intracranial lesions and found that abscess had mean ADC value of 0.35±0.11, acute arterial infarcts had 0.44±0.11, ADEM had 0.38±0.06, encephalitis had 0.38±0.04, glioma had 0.47±0.02, HIE had 0.36±0.03, ICH had 0.58±0.17, lymphoma had 0.52±0.15, meningioma had 0.61±0.16, metastasis had 0.51±0.03, subacute arterial infarct had 0.44±0.11, TBM had 0.48±0.05 and diffuse axonal injury, pontine myelinolysis and venous infarct had mean ADC value was 0.43, 0.52 and 0.42 respectively

Conclusion- The diffusion weighted MR images should be interpreted along with other sequences and also along with clinical details of the patient.
