Conditions
Brief summary
The high resolution chest scan is the gold standard for the screening of interstitial lung disease, but this remains an onerous examination, and irradiating. Ultrasound could be used to detect these disorders with a very good sensitivity and specificity. This exam offers the advantage of being non radiating, inexpensive, and accessible to the rheumatologist who already uses it in their daily practice. The investigators want to assess the lung ultrasound performance compared with the gold standard. Patients will be included during a regular follow-up consultation with their referent rheumatologist. If there is an indication of first line biotherapy or targeted therapy the doctor will propose to the patient to participate in the study, give him the information leaflet, collect orally non-opposition, and will complete a survey for evaluation of the general health and potential risk factors for interstitial lung.
Interventions
OTHERLung sonography
Realization of a lung sonography with scoring of the number of B-lines exploring 14 intercostal spaces. Duration of the exam : twenty minutes. Recording for a second analysis by another lung specialist.
