随着高场强磁共振的出现,磁共振检查在临床上应用更为广泛,磁共振增强扫描对诊断的价值也进一步为大家所公认。传统认为磁共振增强所用的造影剂使用起来相当安全,一般无过敏反应(?)现笔者在临床工作中遇到(?)例在使用钆喷酸葡胺(Gd-DTPA)造影剂后,出现过敏反应。现报道如下,旨在引起我们在MR检查工作中,对造影过敏反应的重视。 例1,男州,42岁。因主诉头痛、头晕、呕吐等症状,在外院行CT平扫疑颅内占位性病变,因有碘造影过敏史未能作增强扫描明确诊断,建议到我院作磁共振扫描检查,以确诊并作术前定位。 MR扫描前准备:打开静脉通道(留针固定)作自动注射 With the emergence of high field MRI, magnetic resonance imaging is more widely used in clinical practice, and the value of MRI in diagnosing is further recognized by all. Traditionally, the contrast agents used in MR imaging have been shown to be quite safe to use and generally have no allergic reaction (?). We now encounter (?) Cases in clinical practice after Gd-DTPA contrast agents Allergic reaction. Now reported as follows, designed to cause us in the MR inspection work, the importance of contrast allergic reactions. Example 1, Male, 42 years old. Due to complaints of headache, dizziness, vomiting and other symptoms in the outer hospital line CT scan suspicion of intracranial space-borne lesions, because of iodine contrast allergy history failed to make an enhanced scan a clear diagnosis, it is recommended to our hospital for magnetic resonance scan examination to confirm And preoperative positioning.
