52 patients with cerebral tumours were examined by both CT and MR. Contrast media containing iodine were used in CT, whereas in MR a paramagnetic contrast medium (gadolinium-DTPA) was applied by IV injection. A comparison of CT and MR findings showed that with both methods it was often not possible to achieve sufficient visualization and delineation of tumour tissue without employing a contrast medium. After application of the contrast medium, the shape and size contrast enhancement in the tumour tissue in both CT and MR was practically identical. This enables direct visualization of the tumour, superior delineation from the adjacent tissue, and differentiation between oedema and tumour, resulting in effective treatment planning which would otherwise not be possible.
52例脑肿瘤患者接受了CT和MR检查。CT检查使用含碘造影剂，而MR检查则通过静脉注射应用顺磁性造影剂（钆-DTPA）。CT和MR检查结果的比较表明，在不使用造影剂的情况下，两种方法通常都无法充分显示和勾勒肿瘤组织。应用造影剂后，CT和MR检查中肿瘤组织的形状、大小及强化情况实际上是相同的。这使得能够直接观察肿瘤，更好地将其与相邻组织区分开来，并区分水肿和肿瘤，从而制定有效的治疗方案，否则这是不可能实现的。
