自1895年伦琴发现X射线以来,医学影像学发生了惊人的变化,使与之相关的新兴分支学科不断涌现。以介入放射学、核医学、超声医学、CT及MRI为主要手段的肿瘤影像学,不仅突破了传统诊断学范畴,还涉及了治疗学的诸多方面。为预防和早期发现肿瘤提供了较好的形态学以及功能改变的信息,明显地提高了肿瘤的治愈率。大肠癌为一种常见的恶性肿瘤,治疗的关键在于肿瘤的早期发现、早期治疗。下面介绍一些临床上常用的诊断方法。 1 钡灌肠与气钡双重对比造影检查 X线检查是大肠癌最基本的检查方法,普及较广。因空腔脏器的对比度较差,常常要辅以钡剂或气钡双重对比造影。大肠癌在钡灌肠或气钡双重造影下有如
Since Roentgen’s discovery of X-rays in 1895, there have been dramatic changes in medical imaging, and new emergencies related to it have emerged. Tumor imaging based on interventional radiology, nuclear medicine, ultrasound medicine, CT, and MRI not only broke through traditional diagnostics, but also involved many aspects of therapeutics. It provides better morphological and functional information for the prevention and early detection of tumors, significantly improving the cure rate of the tumor. Colorectal cancer is a common malignancy. The key to treatment is early detection and early treatment of cancer. Here are some clinically common diagnostic methods. 1 double barium enema and contrast contrast examination X-ray examination is the most basic method of colorectal cancer inspection, widely used. Due to the poor contrast of hollow organs, it is often supplemented with double contrast agents such as tinctures or pneumatics. Colorectal cancer is like a double contrast with barium enema or gastroparesis
