Table 2 General MRI findings of the selected group patients (n = 60)
Disorder | Number | Conventional MRI findings | DWI |
|---|---|---|---|
1. Hypoxic ischemia injury (HII) | 39 (65%) | According to the severity | Restricted diffusion in affected areas in acute phase |
2. Metachromatic leukodystrophy | 6 (10%) | High T2/FLAIR signal in the deep white matter sparing the U-fibers with tigroid pattern | Restricted diffusion in affected white matter |
3. BTBGD | 4 (6.7%) | High T2/FLAIR signal in both basal ganglia, thalami, and the white matter becomes resolved after treatment | Restricted diffusion in acute phase |
4. Leigh disease | 4 (6.7%) | High T2/FLAIR signal in the basal ganglia, thalami, brainstem, and the white matter | Restricted diffusion in acute phase |
5. Periventricular leukomalacia (PVL) | 3 (5%) | High T2 periventricular foci, minimal blooming at T2* for hemorrhage | Early restricted diffusion with normalization within 5–7 days |
6. MELAS | 2 (3.3%) | Multiple subcortical and cortical infarct-like lesions, with variable degrees of generalized cerebellar and cerebral atrophy with frequent involvement of the parietal, occipital, and the basal ganglia. | Restricted diffusion in acute phase |
7. Non-ketotic hyperglycinemia | 2 (3.3%) | Diffuse high T2 and FLAIR signal of the white matter and the cerebral cortex | Restricted diffusion in acute phase |
