Abstract

INTRODUCTION

Magnetic resonance imaging (MRI) is the preferred neuroradiologic tool for evaluating the sellar region. Pituitary adenomas account for about 15% of primary intracranial tumors. The optimal time for postoperative MRI of central nervous system neoplasms is 48 hours after surgery. Nevertheless, controversy exists regarding the timing of postoperative MRI in the sellar region. This study analyzed the sellar MRI findings of patients with pituitary adenoma at different times before and after surgery. Finally, we suggest the optimal time for postoperative sellar MRI imaging in patients with pituitary adenoma.

METHODS

A total of 28 patients with pituitary adenoma were evaluated. All patients did four sellar MRIs. The first MRI was done before surgery, and three were done 48 hours, two weeks, and three months after the surgery. Finally, the MRI findings at different times were compared to each other.

RESULTS

The pituitary gland and adenoma signals were constant at all time points. The signal of the packing material showed no differences in T1-weighted and T1-weighted with contrast sequences but showed changes in T2-weighted sequences.

CONCLUSION

Contrary to other intracranial neoplasms, there were no apparent changes in MRI signal intensity during the 3 months after surgery in patients with pituitary adenoma. There was also no superiority of one time point for performing follow-up imaging.

摘要

引言

磁共振成像（MRI）是评估鞍区的首选神经放射学工具。垂体腺瘤约占原发性颅内肿瘤的15%。中枢神经系统肿瘤术后MRI的最佳时间是术后48小时。然而，关于鞍区术后MRI的时机仍存在争议。本研究分析了垂体腺瘤患者手术前后不同时间的鞍区MRI表现。最后，我们提出了垂体腺瘤患者术后鞍区MRI成像的最佳时间。

方法

共评估了28例垂体腺瘤患者。所有患者均进行了四次鞍区MRI检查。第一次MRI在手术前进行，另外三次在术后48小时、两周和三个月进行。最后，将不同时间的MRI表现相互比较。

结果

垂体和腺瘤信号在所有时间点均保持恒定。填充材料的信号在T1加权和T1加权增强序列中无差异，但在T2加权序列中显示出变化。

结论

与其他颅内肿瘤相反，垂体腺瘤患者术后3个月内MRI信号强度无明显变化。进行随访成像时，也没有一个时间点具有优势。
