Comparison of the Diagnostic Accuracy: US-guided Percutaneous Lung Biopsies vs CT-guided in Peripheral Lung Lesions

The ultrasound investigation will be conducted using the ultrasound machine supplied to the Center involved in the trial and usually used in eTTNA procedures. Before the procedure, the vital signs of the patient will be noted and each operator will choose the most appropriate position for the sampling, based on the location of the lesion. The thoracic area to biopsy will then be defined and then there will be the setting of the sterile field. At this point, local anesthesia with a maximum of 20ml of 2% lidocaine will be administrated, marking down this time as the time of the beginning of the procedure. 18 Gauge needles will be used to collect the sample. For each patient, there will be collected a minimum number of one and a maximum number of three bioptic sampling .
