Idiopathic Pulmonary Fibrosis (IPF) as the name suggests is a progressive disorder with no known aetiology. It is characterised by the thickening of the alveoli due to scarring resulting in cough. It is known to primarily occur in older adults over 60 years of age. The findings of IPF have a known association of Usual Interstitial Pneumonia (UIP) (Raghu et al., 2011; Kawano-Dourado & Kairalla, 2013; Wells, 2013). It has been deemed that the prognosis is generally poor when UIP has been confirmed (King et al., 2001b). The median survival rate of IPF is 50%, typically around two years after diagnosis (Raghu et al., 2011; King et al., 2001b).

(prevalence of nearly 90%) (Patti et al., 2005; Raghu et al., 2006a; Sweet et al., 2007; Tobin<br />

et al., 1998). Though a causal association is uncertain, additionally it has been postulated that<br />

gastroesophageal reflux may be a risk factor for microaspiration, and this may be significant<br />

in the aeitiology and pathogenesis of IPF (Lee et al., 2010). Patients with IPF have decreased<br />

survival with notable coronary artery disease in contrast with those with mild or no disease,<br />

an interesting observation given the prevalence of the disease and confirmation that few<br />

patients with IPF die due to cardiac reasons (Nathan et al., 2010). Bronchogenic carcinoma<br />

moreover happens with enhanced recurrence in IPF (9.8 to 38%) and has a considerable<br />

influence on prognosis (Bouros et al., 2002).<br />

Radiographic Predictors:<br />

The radiographic norm in the assessment of IPF is the HRCT of the chest, providing<br />

vital diagnostic and prognostic details. Numerous parenchymal deformities can be evaluated<br />

and determined, comprising consolidation, reticulation, extent of ground-glass opacities and<br />

honeycombing. Honeycombing and reticulation are usually merged to generate an overall<br />

degree of fibrosis score. The overall pattern can be additionally classified by its uniformity<br />

with the common interstitial pneumonia (UIP) pattern.<br />

The overall degree of fibrosis out of these discrete CT observations has been<br />

constantly exhibited to associate with disease seriousness variables on pulmonary function<br />

tests and prognosis (Mogulkoc et al., 2001; Battista et al., 2003; Lynch et al., 2005; Shin et<br />

al., 2008; Best et al., 2008; Sumikawa et al., 2008). Quantification of fibrosis fascinatingly<br />

may be programmed by a computer system and speculate survival (Iwasawa et al., 2009).<br />

The UIP pattern on HRCT (basically basilar and subpleural honeycombing) has also<br />

been exhibited to simulate a worse prognosis in patients with IPF in contrast with those<br />

having atypical HRCT observations, indicating that the HRCT pattern computes prognostic<br />

details to histopathologic diagnosis (Flaherty et al., 2003b). Other studies although exhibited<br />

that in patients with histologic UIP, the prognosis of patients with an atypical pattern and the<br />

UIP pattern on HRCT are alike (Lynch et al., 2005; Sumikawa et al., 2008).<br />
