| Abstract: | ObjectiveTo study the characteristics of m
aximum intensity projection (MIP), one of multiplanar volumetric reconstruction (MPVR) techniques, with spiral CT and to assess the advantages of the reconstructed vascular images.
Materials and MethodsMIP was adopted in 10 norma
l individuals, including head blood vessels (〖WTBXn〖WTBZ=5) and portal vein with its branches (=5).
ResultsThe fourth branches of encephalic artery
and the fifth affiliated branches of portal vein were clearly displayed.ConclusionMIP, when used skillfully, can offer d
istinct images of blood vessels with the diameter over 2～3mm. Besides, the images can be viewed from any arbitrary direction, thus, more useful information can be obtained. |
