摘要/Abstract

摘要： 目的　观察前海绵间窦（AICS）的MRI影像学特征。方法　连续收集72例垂体增强MRI，包括32例正常体检者和40例垂体腺瘤者。通过多层面MRI观察AICS的影像特征，并给予分型。在正中矢状位平面上，以蝶骨平台延长线为A线，经AICS做一与A线平行的B线，在鞍底做一与A线平行的切线C线，测量A与B间距a，B与C间距b，分析AICS在蝶骨平台与鞍底之间的相对位置关系。结果　72例中，完整型AICS组、不完整型AICS组、无AICS组分别占65.28%（47例）、26.39%（19例）、8.33%（6例）。完整型AICS在T1WI TSE增强影像显示为垂体上前方、鞍结节顶点下方的连续高信号影。测得完整型AICS的a/（a+b）值正常体检组为（0.31±0.10），垂体腺瘤组为（0.20±0.16），二者间存在统计学差异（P<0.05）。结论　在T1WI TSE MRI上，正常体检者AICS具有较好的显示，而垂体腺瘤者AICS显示明显减少且更趋于不连续。

Abstract: Objective　To observe the imaging characteristics of the anterior intercavernous sinus（AICS）in MRI.　Methods　72 patients who took pituitary enhanced MRI examination were collected continuously, including 32 normal physical examinations and 40 pituitary adenomas. The imaging characteristics of AICS were observed by multi-slice MRI, and classified. In the sagittal plane of midbrain aqueduct, an extension line of the sphenoidal planum was line A, line B was a parallel line with line A passing through the highest signal of AICS, and line C was a parallel line with line A at the sellar floor. Value a was the distance between line A and line B, and Value b was the distance between line B and line C. Then the relative position of AICS between sphenoidal planum and sellar floor was analyzed. Results Among the 72 cases, the complete AICS group, the incomplete AICS group, and the non-AICS group were 47 cases (accounted for 65.28%), 19 cases (accounted for 26.39%), and 6 cases (accounted for 8.33%) cases, respectively. The complete AICS was located above the anterosuperior pituitary and below the apex of the tuberculum sellae on the T1WI TSE enhanced MRI. a/ (a+b) value of the complete AICS in the normal group was (0.31±0.10), and (0.20±0.16) in the pituitary adenoma group. There were statistical difference between the normal group and the pituitary adenoma group (P<0.05).　Conclusions　In T1WI TSE MRI, AICS imaging has higher imaging in normal medical examinations, but AICS imaging decreases and tends to be discontinuous in pituitary adenomas.
