Proton magnetic resonance spectroscopy of the thalamus and hypothalamus in patients with first-episode depression / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the presence of abnormal metabolism in the thalamus and hypothalamus in patients with first-episode depression.</p><p><b>METHODS</b>Thirty drug-naive patients with first-episode depression and 30 age-matched controls were scanned with proton magnetic resonance spectroscopy ((1)H-MRS) for Naa, Cho, Cr and mI.</p><p><b>RESULTS</b>Compared with the control group, the patients showed significantly reduced mI and mI/Cr of the hypothalamus, reduced mI/Cr of the left thalamus, and lowered Cho, ml, and ml/Cr of the right thalamus (P<0.05).</p><p><b>CONCLUSION</b>Patients with first-episode depression may have myo-inositol and phosphoric acid metabolism disorder in the thalamus and hypothalamus with malfunction of cellular osmotic pressure adjustment mechanism. Abnormal mI/Cr in the thalamus and hypothalamus may represent an important biochemical change in advanced patients with depression.</p>

CT and MRI Study of Brain Lesions in Carbon Monoxide Intoxication / 实用放射学杂志

Objective To evaluate CT and MRI features of brain lesions in CO poisoning and to compare the ability of detecting rate of lesions by CT and MRI.Methods CT and MRI appearances in 52 cases with CO poisoning were analysed and compared.Results Necroses and degenerations of globus pallidus in 9 cases,cerebral white matter demyelination in 3 cases and brain atrophy in 3 cases were showed by CT.The detecting rate was 28.8% by CT while,necroses and degeneration of glodus pallidus were observed in 24 cases and white matter change in 7 cases were observed by MRI,the detecting rate was 59.6% which was higher than that of CT (?
