Brilliance 16 slice spiral ct instrument

The subjects were informed to inhale and hold their breath; the pre-scan method was used to obtain the best level to show the lesions in the patient; the multi-slice spiral CT machine (Philips Brilliance 16-slice spiral CT instrument, SFDA certified no. 2009 No. 3300931, Amsterdam, The Netherlands) was set to 120 kV, 130 mA; the layer thickness and the layer distance were both 10 mm; and the thread pitch was 1. An appropriate window width and position were chosen for observation to make the diseased tissue clearer and more intuitive. Three experienced doctors were asked to read the image, and the final results were defined by all doctors.

The location of the lesions in patients' lungs was clarified according to the chest CT, and the patients were asked to take appropriate positions. The lesions were scanned with 3 mm in each layer by using a CT scanner (Philips brilliance16-slice Spiral CT instrument; CFDA (I) 20093300931), and metal bar localizers were placed in the corresponding body surface sites. After that, the scanning continued, to determine the appropriate puncture sites, and the puncture angle, depth, etc., were calculated by measuring before the puncture sites were disinfected and given local anesthesia. Then, a biopsy gun (Guangzhou Qihe Medical Instrument Co., Ltd.; Guangdong Food and Drug Certified No. 20181153) was used after the puncture needles were confirmed inside the mass by scanning, and the biopsy tissues were fixed with 10% formaldehyde solution before detection.
