磁共振成像技术和设备在垂体腺瘤诊疗中的研究进展

The Application Progress of Magnetic Resonance Imaging Techniques and Equipment in the Diagnosis and Treatment of Pituitary Adenoma

垂体腺瘤在颅内良性肿瘤中的发生率最高,其主要临床症状为视觉障碍和内分泌异常。磁共振成像是显示垂体腺瘤及其周围结构的首选方式;但在某些情况下,其不能反映视觉通路的微观结构损伤,也不能区分活动性肿瘤和术后组织重塑。近年来,一些磁共振成像技术和设备在垂体腺瘤的应用中展现了较多研究进展,例如弥散张量成像、超高场强磁共振、术中磁共振和分子影像等,它们在评估垂体腺瘤的诊断、治疗和预后方面具有重要作用。本文针对这些磁共振成像技术和设备在垂体腺瘤的检出、诊断及疗效评估中的应用进行简要综述。

Pituitary adenoma is the most common benign tumor in the cranial cavity,and its main symptoms are visual impairment and endocrine hormone disorder.MRI is the preferred method to show the pituitary adenoma and its surrounding structures,but in some cases,it cannot reflect the microstructural damage of the visual pathway,nor can it distinguish between active tumor and posttreatment remodeling.In recent years,some magnetic resonance imaging techniques and equipments have shown a lot of research progress in the application of pituitary adenoma,such as diffusion tensor imaging,ultra-high field magnetic resonance imaging,intraoperative magnetic resonance imaging,and molecular imaging,etc.,which have important roles in evaluating the diagnosis,treatment and prognosis of pituitary adenoma.This article briefly reviews the application of these magnetic resonance imaging techniques and devices in the detection,diagnosis and efficacy evaluation of pituitary adenoma.
