A study on role of diffusion weighted magnetic resonance imaging features of intracranial pathologies – a series of 115 cases.

Dr. S Venkateswara Rao, Dr. Syed Nazneen

Abstract :

depends on the random movement of water molecules within and between the intracellular and extracellular spaces. Regions with restricted mobility of water molecules yield a greater DW–MRI signal and appear ight. In apparent diffusion coefficient (ADC) maps, regions that contain high water mobility appear ight.

Objective:

The objectives of the study were to describe the imaging characteristics of intra cranial lesions on DWI and to compare these features with ADC and T2W images.

Materials and methods:

A descriptive MR Study was undertaken in 115 patients detected to have intracranial lesions on DW MRI of the ain in ASRAMS. In all these patients the DWI findings were noted and correlated with ADC and T2 FLAIR images. All the MRI scans in this study were performed using 1.5 T MRI scanner (SIEMENS MAGNETOM AVANTO).

Duration of study: The study was carried over a period of 1 year from August 2016 to July 2017.
