Neuroimaging Features of the Chronic Cerebral Ischemia of Hypertonic and Atherosclerotic Genesis - 09/06/15
Résumé |
Background |
The great number of subjective and descriptive characteristics of the chronic cerebral ischemia (CCI) arise a question of development of magnetic-resonance tomographic (MRT) criteria for CCI in relation to its genesis (hypertonic and atherosclerotic).
Purpose |
Concretization of MRT features of CCI in relation to its genesis.
Material and Methods |
MRI investigation was performed in 77 patients with CCI of average age 58,2±0,6 years. Patients were divided into 2 groups. Group 1 included 31 patients with CCI of hypertonic genesis, group 2 consisted of 46 patients with CCI of atherosclerotic genesis. M
Results |
Ischemic focuses were found subcortically in 22 (71,0%), periventricullary – in 9(29,0%) patients of group 1, in group 2 – in 18(39,1%) and 28(60,9%) P<0,01, respectively. In group 1 the single focuses were in 2(6,5%) patients, few – in 10(32,3%) and multiple – in 19(61,3%) patients. In patients of group 2: single – in 14(30,4%), few – in 21 (45,7%) and multiple – in 11(23,9%). The small sites were diagnosed in 13(41,9%) patients of group 1 and in 34(73,9%) in group 2 (P<0,01). The large sites were found in 18(58,1%) and 12 (26,1%) P<0,01, respectively. The total area of of leusoareosis in regimen T2 was 8,6±1,2cm2 in group 1, and 3,5±0,5 cm2 in group 2.
Conclusion |
MRT picture of CCI of hypertonic genesis was characterized by multiple, large focuses, predominantly cubcortically distributed, by diffusive-confluent leucoareosis. MRT findings of atherosclerotic genesis were differed by small periventricular areas and local leucoareosis.
