ENFERMEDAD PULMONAR INTERSTICIAL DIFUSA (EPID)
Revista Cuarzo, 2016 Si bien es cierto que la radiografía simple del tórax permite sospechar la presencia de enfermedad pulmonar instersticial, la tomografía axial computarizada (TACAR) es más sensible y específica en la valoración de pacientes con esta enfermedad. En este artículo se trata sobre los patrones básicos que permiten identificar los diversos grupos de EPID ...
