ABSTRACT
A study aimed at developing the pulse consequence, the double inversion recovery (DIR), using low field magnetic tomography, and assessing its effectiveness in the detection of intracerebral hematoma. The research has been conducted at "Ellipse" MR tomograph. The new pulse sequence has been created by the modification of the regular FLAIR, its technical parameters were as follows: the first TI - 90 ms, the second TI - 1300 ms, TR - 4665 ms, echo - 3. Twenty-seven patients have been enrolled in the study. The tissue contrast coefficients on FLAIR and DIR images have been compared. It has been shown that the contrast coefficient of normal brain structures and brain lesions on the DIR images in regard to the white matter are significantly higher than on the FLAIR images. Results of the study revealed that the dynamics of MR symptoms of intracerebral hematoma is faster on the DIR images compared to the FLAIR ones. This finding can be used for detection of intracerebral hematoma in difficult clinical cases.
