Stroke also known as a brain attack. It is a major cause of long-term disability that occurs, when blood supply to a part of the brain is blocked or a blood vessel in the brain bursts, resulting in damage or death to parts of the brain. Since stroke can lead to lasting brain damage, long-term disability, or death, the study focused on the time of the stroke. To investigate this, the research involved carrying out MRI examinations on 87 patients (48 males and 39 females) who were referred by specialist neurologists in Baghdad, Iraq. The exams were conducted using a Philips Achieva 1.5 tesla MRI machine, at the Academic Medical Center AMC and included four basic sequences (T1, T2, DWI, and FLAIR), with DWI being the most important. The correlation between symptom onset and time of stroke was analyzed using Spearman coefficient, revealing a significant relation with a high degree of 0.927 at a significance level of 1%. Chisquare tests were used to assess the relationships between symptom onset and time of stroke, age groups of patients with hypertension, and the time of stroke with the T1, T2, FLAIR, and DWI sequences.
