SPECT胃黏膜显像在胃中间横带研究中的价值

The value of gastric mucosa SPECT in the study of midgastric transverse band

摘要

摘要:
目的探讨SPECT胃黏膜显像在胃中间横带（MTB）研究中的价值。
方法对45名健康成年人分别进行SPECT胃黏膜和胃排空显像，并进行图像面积、放射性计数/像素比值的统计学分析。
结果近端与MTB、远端与MTB及全胃与近端、远端的放射性计数/像素比值差异均具有统计学意义，说明在胃黏膜显像图像上也存在类似于胃排空核素显像图像上所显示的MTB，而且胃黏膜显像图所显示的MTB与胃排空显像图的MTB一致，均表示相同的临床意义。
结论胃黏膜显像是一项定性检查，它通过核素的分布变化间接反映胃黏膜细胞的变化，MTB是胃的粘液细胞相对匮乏的一个区域，由此也可解释MTB在胃动力学上容受功能相对较弱的原因。

Abstract:
Objective To investigate the value of SPECT gastric mucosa imaging in the study of midgastric transverse band(MTB).
Methods SPECT gastric mucosa and gastric emptying imaging were performed in 45 healthy adults, and the image area and count/pixel ratio were statistically analyzed.
Results Significant differences were found between proximal and MTB, distal and MTB, whole stomach and proximal, whole stomach and distal count/pixel ratio. MTB was also observed in gastric mucosa imaging, and the MTB in gastric mucosa imaging indicated the same clinical significance as that of the MTB in gastric emptying.
Conclusions Gastric mucosa imaging can be used for qualitative determination, and alterations in the distribution of radionuclide indirectly reflect the changes in the gastric mucosal cells. MTB is a region that lacks gastric mucous cells; thus, this region is relatively weak in gastric receptivity dynamics.
