Can X-rays effectively diagnose pulmonary fibrosis?
Thank you for asking
I read your question and i understand your concern. For pulmonary fibrosis, high resolution computed tomography scans are ideal, chest x rays can help but findings are less specific. Pulmonary hypertension associated with it is best assessed with transthoracic echocardiography. One can go for bronchoscopies and Video assisted thoracoscopic surgeries to study it further.
Airway remodeling is diagnosed with both invasive and noninvasive ones. Invasive is bronchoscopy and biopsy and noninvasive is markers associated with it like cytokines in blood etc. It usually is associated with asthma patients.
And for pulmonary hypertension , again chest x rays, echocardiographic and doppler studies and transthoracic studies are helpful.
To summaries, x rays have major role compared to nuclear imaging in diagnosing these three studies.
Follow-up questions on airway remodeling:
I. What are the cytokine thresholds above which airway remodeling would be considered probable in asthma patients?
II. How long would uncontrolled, severe persistent asthma have to occur before airway remodeling was a consequence?
III. Is airway remodeling reversible with physical therapy or other modalities - that is, once airway remodeling has occurred in a negative sense in the wrong direction, can airway remodeling occur again but in a positive sense in the right direction?
Thank you for getting back
Remodeling for asthma means when airways get hypertrophied and smooth muscle cells migrate to epithelium in airways and they do it by releasing chemokines and cytokines. So there is no threshold of cytokines to induce remodeling. To make it simpler for you, any uncontrolled asthma or noncompliant medicine use will lead to cytokines production enough to induce remodeling.
As far as how long is concerned , that part is highly variable to every subject and can vary from a few months to years subjected to every patient and can not be quantified.
Remodeling is a fibrosis, it is preventable but once remodeled, not reversible.

I hope it helps.
I. How are emphysema, COPD, and pulmonary pneumonitis effectively diagnosed via imaging or other means?
II. What are typical medical-grade O2 inhalation protocols for people with breathing difficulties due to pulmonary pathology?
Beyond scope of discussion
Thank you for getitng back to me
I am afraid the answers to above mentioned questions are beyond the scope of discussion of this forum. Imaging modalities and pulmonary functions tests are mainstay of diagnosis and oxygen is given either in short term or Long term we call that long term oxygen therapy.
I believe that is enough to explain as beyond it, explanation surpasses the scope of discussion of this forum.
