May 04, 2022
It is a percutaneous puncture of the chest under CT guidance. CT interventional radiology is a percutaneous non-transvascular interventional technology, which includes CT-guided percutaneous biopsy and interventional therapy. CT can be used for the guidance of interventional techniques in various systems of the whole body, and CT can be used for all parts that cannot be guided by fluoroscopy and ultrasound. CT scan has high resolution and good contrast, and can clearly display the size, shape, location of the lesion and the spatial relationship between the lesion and surrounding structures. Enhanced CT scan can understand the blood supply of the lesion and the relationship between the lesion and the adjacent blood vessels. CT-guided biopsy can accurately determine the needle entry point, angle and depth, avoid damage to blood vessels, nerves and important structures adjacent to the lesion, and improve the accuracy and safety factor of the biopsy technique. CT-guided biopsy is one of the important means of diagnosis and differential diagnosis. The basis of imaging manifestations is pathological changes. Different pathological changes sometimes have similar imaging manifestations. This is a difficult problem in diagnosis and differential diagnosis. Therefore, biopsy before treatment is very necessary. Biopsy technique is safe, with low complication rate and high accuracy rate, and it is an examination method worthy of promotion.
