“…Ourchestradio graph scoring method is similar to that used in otherstudies [2,4], andtheinterobserver vim ation between the two observers' scores agreed well for five of the six regions and moderately for one region ( Table 1). The kappa values for interobserver variation ob tamed in this study compare well with those from other studies looking at the radiologic featuresof pneumoniaandbronchiolitis[13â€" 15] and imply that the scoring regime used was reasonably objective. However, grouping patients on the basis of either total radio graphicscoreor regionalmean radiographic scorerevealedno statistically significant asso ciation with oxygenation index.…”

OBJECTIVE. The studysetout to evaluatethe relationshipbetweenthe efficiencyof pul monary oxygenation and the extent of the reimplantation response as revealed on chest radi ography after bilateral lung transplantation.MATERIALS AND METHODS. Postoperativechestradiographsof 31 patientswho had undergone bilateral lung transplantation were evaluated for the extent of the reimplanta tion response. For each patient, the contemporaneous oxygenation indexes (partial pressure of oxygenin arterialblood divided by fraction of inspiredoxygen)werecalculatedandcorre lated with a radiographic score produced from the evaluation of chest radiographs. RESULTS. The methodof evaluatingchestradiographs for theextentof thereimplantationresponse was shown to be reproducible. Although mean oxygenation indexes were found to de creasewith increasing radiographic scores, thistrendwasnot statisticallysignificant.CONCLUSION. Althoughtheextentof the reimplantationresponse on theearly postop erative chest radiography inversely correlated with the oxygenation efficiency of the trans planted lungs, this finding was not statistically significant.

“…As previously mentioned, bronchiolitis is a difficult diagnostic category, in that no feature is unique to this disorder. But the kappas shown in Table I for the reliability of individual features are by no means low for other radiological diagnoses (Coblentz et al, 1991). As will be shown in Experiment 2, some of the films in this 50-film set were diagnostically reasonably straightforward, and others were consistently borderline.…”

We assessed the prevalence of interstitial lung disease (ILD) in a cohort of smokers included in a lung cancer screening trial.Two observers independently reviewed, for the presence of findings consistent with ILD, the computed tomography (CT) examinations of 692 heavy smokers recruited by the Multicentric Italian Lung Detection (MILD) trial. Four CT patterns were considered: usual interstitial pneumonia (UIP), other chronic interstitial pneumonia (OCIP), respiratory bronchiolitis (RB) and indeterminate. Subsequently, the evolution of ILD in those subjects who had undergone a repeat CT examination after 3 yrs was assessed.The UIP pattern and the OCIP pattern were identified in two (0.3%) out of 692 and 26 (3.8%) out of 692 patients, respectively; 109 (15.7%) out of 692 patients showed CT abnormalities consistent with RB, while an indeterminate CT pattern was reported in 21 out of 692 (3%) patients. Age, male sex and current smoking status were factors associated with the presence of OCIP and UIP (combined) pattern, although the relationship did not attain statistical significance. A progression of the disease was observed in three (25%) out of 12 subjects with OCIP who underwent repeat CT after 3 yrs.Thin-section CT features of ILD, probably representing smoking-related ILD, are not uncommon in a lung cancer screening population and should not be overlooked.
