Percutaneous lung biopsy. a Axial routine diagnostic image in a patient with solid lung lesion at the upper right lobe. b Effective atomic number-based reconstruction at the same level: the lesion is characterised by inhomogeneous intralesional atomic number with a central area showing a reduced atomic number (yellow–red) and a medial eccentric area showing a higher atomic number (light blue, asterisk). c Intraprocedural cone beam computed tomography (CBCT) shows that the needle has been located in the area with the highest atomic number. d Axial routine diagnostic image in a patient with solid lung lesion at the lower left lobe. e Effective atomic number-based reconstruction at the same level: the lesion is characterised by inhomogeneous intralesional atomic number with a central area showing a reduced atomic number (yellow–red) and an external circular area showing a higher atomic number (light blue, asterisk). f Intraprocedural CBCT shows that the needle has been located in the area with the highest atomic number
