From: Differentiating combined pulmonary fibrosis and emphysema from pure emphysema: utility of late gadolinium-enhanced MRI

Fig. 3

Fifty-seven-year-old man with progressive breathlessness, FEV1 2.4 L/s, LAV 7.6%. a Axial high-resolution computed tomography showed moderate centrilobular emphysema in the upper lobes (arrows). b It was unclear at multidisciplinary conference whether the abnormal regions in the lower lobes (arrows) represented emphysema or fibrosis. c Late gadolinium-enhanced magnetic resonance imaging of the upper lobes showed no contrast enhancement, but in d, definite contrast enhancement in the abnormal regions in the lower lobes (arrows) was consistent with fibrosis. FEV1, Forced expiratory volume in one second; LAV%, Low attenuation value percent
