Abstract:

In this paper,2,4,6-triiodophenol-ethylcellulose microsphere was developed by in2liquid drying method, in order to increase the granularity of the X2ray CT contrast agent and to prevent the blood vessel X-ray CT contrast agent from exuding through the vascular wall to the tissue. The influences of the composition ratio of 2,4,6-triiodophenol : ethylcellulose to the microspheres ’ appearance and diameter, and the entrapment of 2,4,6-triiodophenol were studied. It was found that when the composition ratio was 1∶2, the microspheres’ appearance was round, the average diameter was only 3168μm, and the entrapment of 2,4,6-triiodophenol was 4114 %.

Key words: in-liquid drying method,2,4,6-triiodophenol, ethylcellulose microsphere, blood vessel X-ray CT contrast agent
