Intracerebral Haemorrhage (ICH) is an important public health problem leading to high rates of death and disability in adults. Early and reliable identification of the stage of ICH is vital when choosing the proper treatment and estimating patient’s diagnosis and outcome. Diffusion Weighted - Magnetic Resonance Imaging (DW-MRI) presents a variation in the image signal intensity characteristics relative to the different stages of ICH and thus an increased understanding of the progression of the signal intensity variations on Diffusion Weighted (DW) images, subsequent to the onset of ICH, is valuable. In the present paper an effort was made to quantify the variations in the signal intensity characteristics on DW images, at evolving stages of ICH, for 32 subjects, by means of Signal Intensity Gradient (SIG) imaging metric. The relative increase in the SIG values (RSIG) for the subjects with ICH was in the range of (3.83 – 35.67) times compared to their corresponding SIG values on the contralateral normal side. The observed RSIG values were elevated in Stage 1 (Hyperacute: 14 days) of ICH. Also a negative correlation (r = − 0.97) was observed between the RSIG values and the evolving stages of ICH. Therefore, the progression of the RSIG values could be supportive in understanding the developmental stages of ICH, and further be helpful in predicting the ICH stage and providing treatment at the appropriate time. |
