This paper presents a clinical case of a 39-year-old pregnant woman with respiratory signs of the novel coronavirus Covid-19 infection. Chest MRI showed bilateral lesions in basal segments. The PCR test was positive. A lung condition was assessed without loss of significant diagnostic information. Besides that, the absence of exposure to ionizing radiation allowed to avoid a high loading dose on the patient and the fetus. This case reveals potential opportunities of MRI in the diagnosis of pulmonary pathology without exposure to ionizing radiation, especially in patient risk groups (children, pregnant women, etc.).
