The results obtained from contrast-enhanced MRI in 21 patients with masses in the pineal region are reported. The use of gadolinium-DTPA results in intensive contrast uptake by the tumour; this produces better definition of the tumour and more exact delineation from neighbouring structures. This is of importance in judging resectability and in choosing the operative approach. During chemotherapy or radiotherapy, it provides reliable demonstration of the success of treatment and accurately demonstrates the size of the tumour and the presence of necrosis. On the other hand, histologic classification of pineal tumours is possible only occasionally.
报告了21例松果体区肿块患者的对比增强磁共振成像（MRI）结果。钆喷酸葡胺的使用导致肿瘤强烈摄取对比剂；这能更好地界定肿瘤，并更精确地将其与相邻结构区分开来。这对于判断可切除性和选择手术入路很重要。在化疗或放疗期间，它能可靠地显示治疗效果，并准确显示肿瘤大小和坏死情况。另一方面，松果体肿瘤的组织学分类仅偶尔可行。
