(15) The total number of lesions varied, though not greatly, over the whole follow-up, but there was an influence of the clinical course of MS on the pattern of lesions in MR imaging, mostly in respect to the number of confluences and the size of the lesions.
(16) 3) The pressures of the inferior vena cava at the confluence of right and left common iliac veins with 20 and 40mmHg showed no significant difference immediately after the pressurization, but thereafter showed a increasing tendency in the group with 40mmHg (p less than 0.05).
