Was soll ich tun, wenn die CT-Lungenmasse Wasser ansammelt, aber zu klein für eine Punktion ist?

CT interventional diagnosis and treatment technology is under the guidance and monitoring of computer-aided X-ray tomography images, with the help of various minimally invasive diagnosis and treatment instruments, percutaneous puncture of lesions, inspection, live gun, and treatment. The technique, operation and accuracy of free-hand puncture under CT guidance are greatly affected by experience factors. Laser-guided and puncture-guide-assisted CT guidance is easy to operate, has accurate hits, has fewer scanning layers, and has fewer complications. The CT-guided stent can keep the puncture needle "aiming" at the lesion, and the puncture hits the target. This method is easy to operate, has few scanning layers, has a high hit rate, and has few complications. The National People's Congress reduces the difficulty of CT intervention and is easy to popularize and apply. The cannula technology establishes a passage for the biopsy needle, realizes multi-point puncture and multiple sampling, and obtains a satisfactory and sufficient amount of specimens. The injection of hemostatic drugs, anticancer drugs, and medical glue through the trocar can stop bleeding and prevent needle tract planting. , effectively reducing the risk of puncture. The micron injection needle punctures the tumor through the trocar, with less damage, less drug reflux, and improved treatment efficiency. To reduce adverse reactions, CT-guided interventional diagnosis and treatment involves multiple systems, and the accuracy rate of CT-guided puncture is 86 percent -96 percent , and puncture biopsy will not cause tumor dissemination and implantation. It has become one of the important methods for clinical primary diagnosis. , Percutaneous intratumoral injection directly acts on the tumor tissue to achieve the purpose of treatment. Percutaneous ethanol injection and percutaneous acetic acid injection have become one of the recognized methods for the local treatment of liver cancer. Percutaneous hydrochloric acid injection utilizes the main component of gastric juice, hydrochloric acid, to kill cancer cells and coagulate cancer tissue. The activity of inactivating cancer tissue is inexhaustible. 15 times that of ethanol, which can replace absolute ethanol for chemical ablation. CT interventional radiofrequency ablation and microwave ablation for the treatment of liver cancer and lung cancer have become one of the curative methods for tumors. Percutaneous puncture treatment of liver and kidney cysts can replace traditional surgical treatment. With the development of CT and MRI interventional puncture technology, the professional technology of image tomography minimally invasive diagnosis and treatment will bring progress to medicine.
