Percutaneous ultrasound-guided fine needle aspiration cytology of pulmonary lesions: a single centre experience

Purpose: Imaging-guided percutaneous fine needle aspiration biopsy (FNAB) is routinely used for the diagnosis of pulmonary lesions. Computed tomography (CT) is the most common imaging modality used for guidance followed by ultrasound (US). To date there are few data about the use of this technique for the characterization of pulmonary lesions and above all about percutaneous US-guided fine needle aspiration cytology (FNAC). This is considered a reliable method for the diagnosis of malignant lesions despite it has some limitations, such as inadequate sampling and a limited value in the differentiation between ben…
