How Does Chest Puncture Needle Do?

It's a ct guided percutaneous puncture of the chest. ct interventional radiology is a percutaneous non-vascular interventional technique, which includes CT-guided percutaneous biopsy and interventional therapy. ct can be used to guide the interventional techniques of the whole body, and can be used to guide the parts that fluoroscopy and ultrasound cannot guide. ct scan has high resolution and good contrast, and can clearly display the size, shape and location of the lesion and the spatial relationship between the lesion and the surrounding structure. Enhanced ct scan can understand the blood supply of the lesion and the relationship between the lesion and adjacent vessels. Ct-guided biopsy can accurately determine the needle insertion point, Angle and depth, avoid damage to blood vessels, nerves and important structures adjacent to lesions, and improve the accuracy and safety of biopsy techniques. ct - guided biopsy is one of the important means of diagnosis and differential diagnosis. Imaging findings are based on pathological changes. Different pathological changes sometimes have similar imaging findings, which is a difficult problem in diagnosis and differential diagnosis. Therefore, biopsy before treatment is very necessary. Biopsy technology is safe, low complications, high accuracy, is worth promoting a means of examination.
