本文报道了原发性直立性低血压（ＳｈｙＤｒａｇｅｒ’ｓｓｙｎｄｒｏｍｅ，ＳＤＳ）病人脑干、小脑各径线的ＭＲ测量值。结果表明除中脑横径与对照组无差异外（Ｐ＞０．０５）．桥脑、延髓、小脑各径线比对照组缩短（Ｐ＜０．０５）；脑桥横径与中脑、延髓横径之比值与对照组无差异（Ｐ＞０．０５）；而脑干各径线与第四脑室前后径之比值比对照组小（Ｐ＜０，００ｌ）。
This article reports MR measurements of brainstem and cerebellar diameter lines in patients with primary orthostatic hypotension (SDS). The results showed that except for the midbrain transverse diameter and the control group no difference (P> 0.05). The diameters of pons, medulla oblongata and cerebellum were shorter than that of the control group (P <0.05). There was no significant difference in the ratio of the transverse diameter of the pontine to the midbrain and medulla oblongata (P> 0.05) The ratio of diameter to anteroposterior diameter of the fourth ventricle was smaller than that of the control group (P <0,001).
