摘　　要：利用ＣＴ薄层扫描技术对２６例正常成年人的ＡＣ－ＰＣ平面进行了初步研究。结果表明，ＰＣ层面较易确定，使用１．５ｍｍ层厚连续扫描，在每人次扫描中均可看到ＰＣ层面，部分人的ＡＣ不能在ＣＴ片上直接显示，需要通过其与ＦＭ的关系间接确定。按与ＣＭＬ成１０°角的基线扫描，仅５人可得到ＡＣ－ＰＣ层面，其余２１人ＡＣ和ＰＣ不在同一层面，但根据ＡＣ和ＰＣ相差层面数，适当调整扫描基线角度后，可容易获得ＡＣ－ＰＣ层面。How to get the anterior-posterior commissure (AC-PC) slice in the CT scanning is one of the key procedures of functional stereotactic surgery. The scanning modality of AC-PC slice was investigated in 26 healthy adults.With 1.5mm axial cuts, the AC slice needed to be identified according to the relation with Foramen of Monro in some volunteers because the AC was not always visualized. In contrast,the PC slice was easier to be found in all. With the CT scanner setting to 10°above the canthomeatal line, the AC-PC slice was obtained in 5 of the 26 volunteers at the first scanning. The AC and PC weren’t on the same slice in the other 21 volunteers at the first time,but their AC-PC slices were visualized easily after appropriately adjusting the angle of scanner baseline.
