Beskrivelse
Inclusion Criteria:
- Age ≥18 years at enrollment.
- Participant is willing and able to provide written informed consent.
- Able (in the Investigator's opinion) and willing to comply with all study requirements.
- Participant has or is suspected to have one of the following pulmonary conditions:
- Healthy volunteers: aged 18-30 years; no known cardiopulmonary disease; has not smoked tobacco products in the previous 5 years; smoking history, if any, is less than or equal to 5 pack-years; no history of using other inhaled products more than 1 time per week for > 1 year OR
- ILD-PH: ≥18 years; ILD diagnosis; precapillary PH by RHC (mPAP >20 mmHg, PVR >2 WU, PCWP ≤15 mmHg) within the specified window OR
- SSc: systemic sclerosis diagnosis with or without PH
Exclusion Criteria:
- Any condition which, in the opinion of the Investigator, would make it unsafe or unsuitable for the participants to undergo MRI (for example: presence of an implanted or external MRI unsafe device that cannot be removed, body weight exceeding table limitations, inability to lie flat, or severe claustrophobia).
- Inability to hold breath for 10-15 seconds for required imaging or for completion of DLCO measurements.
- Active pulmonary infection or lung cancer.
- Recent respiratory infection or pulmonary disease exacerbation within 4 weeks of screening.
- Participants who are known to be pregnant or lactating.
- Concurrent enrollment and participation in a study which, in the opinion of the Investigator, would interfere with the study compliance, or outcome assessments or would prohibit the collection of the required data points.
