A deep learning algorithm for categorizing high-resolution CT images reported high accuracy  and a research project led by Nagoya University Graduate School of Medicine and Riken used a combination of Deep learning and Machine learning algorithm to accurately diagnose the disease. Differential diagnosis
Recognizing IPF in clinical practice can be challenging as symptoms often appear similar to those of more common diseases, such as asthma, chronic obstructive pulmonary disease (COPD) and congestive heart failure (www.diagnoseipf.com). The key issue facing clinicians is whether the presenting history, symptoms (or signs), radiology, and pulmonary function testing are collectively in keeping with the diagnosis of IPF or whether the findings are due to another process. It has long been recognized that patients with ILD related to asbestos exposure, drugs (such as chemotherapeutic agents or nitrofurantoin), rheumatoid arthritis and scleroderma/systemic sclerosis may be difficult to distinguish from IPF. Other differential diagnostic considerations include interstitial lung disease related to mixed connective tissue disease, advanced sarcoidosis, chronic hypersensitivity pneumonitis, pulmonary Langerhans cell histiocytosis and radiation-induced lung injury. Classification
Idiopathic pulmonary fibrosis (IPF) belongs to a large group of more than 200 lung diseases known as interstitial lung diseases (ILDs), which are characterized by the involvement of the lung interstitium, the tissue between the air sacs of the lung. IPF is one specific presentation of idiopathic interstitial pneumonia (IIP), which is in turn a type of ILD, also known as diffuse parenchymal lung disease (DPLD).The 2002 American Thoracic Society/European Respiratory Society (ATS/ERS) classification of IIPs was updated in 2013.
A recent study from the USA estimated the incidence of IPF to be between 6.8 and 16.3 per 100,000 persons. In the 27 European Union countries, a range of sources estimate an incidence of 4.6–7.4 people per 100,000 of the population, suggesting that approximately 30,000–35,000 new patients will be diagnosed with IPF each year.A recent single-centre, retrospective, observational cohort study including incident patients diagnosed with ILD at Aarhus University Hospital (Denmark) between 2003 and 2009 revealed  an incidence of  4.1 per 100,000 inhabitants/year for ILD. IPF was the most common diagnosis (28%) followed by connective tissue disease-related ILD (14%), hypersensitivity pneumonitis (7%) and non-specific interstitial pneumonia (NSIP) (7%). IPF incidence was 1.3 per 100,000 inhabitants/year.Due to a heterogeneous distribution of the disease across European countries, epidemiological data needs to be updated through a Europe-wide registry for ILD and IPF. Other animals
IPF has been recognized in several breeds of both dogs and cats, and has been best characterized in West Highland White Terriers. Veterinary patients with the condition share many of the same clinical signs as their human counterparts, including progressive exercise intolerance, increased respiratory rate, and eventual respiratory distress. Prognosis is generally poor. Research
A number of agents are currently being investigated in Phase II clinical trials for IPF, including the monoclonal antibodies simtuzumab, tralokinumab, lebrikizumab and FG-3019, a lysophosphatidic acid receptor antagonist (BMS-986020). A Phase II study of STX-100 is also ongoing.
