[Study of high-resolution thoracic computerized tomography and bronchoalveolar lavage in 36 patients presenting with systemic disease and a normal thoracic radiography].

Systemic diseases such as scleroderma (ScI), rheumatoid polyarthritis (PR), Gougerot-Sjögren Syndrome (GS) have a well known propensity for the lungs. Previous studies have shown evidence of disturbed alveolar cell repair as evidence of a sub-clinical alveolitis. The significance of such cases of latent alveolitis remains to be specified. To determine if latent alveolitis was associated with interstitial chest disease which was undetectable by chest X-ray, 36 consecutive patients had an BAL and a high resolution computered tomographic examination (HRTC) (Scl: n = 21; PR: n = 9; GS: n = 6). The patients had normal respiratory function and chest X-ray was normal. Our results showed 17 out of 36 (47%) with a latent alveolitis (the percentage of lymphocytes and of alveolar polymorpho-nuclear neutrophils was superior or equal to 18 and 4% respectively) (Scl: 12/21; PR: 1/9; GS: 4/6). In the cases of scleroderma a neutrophil alveolitis was predominant (9/12) and was associated in 2 cases with a honeycomb lung and evidence of fibrotic lesions using TDM-HR. Those examinations using HRTC which were normal were equally associated with a latent alveolitis (Scl: 6/12; PR: 1/6; GR: 4/5). These results suggest that the alveolitis can preceed the anatomical damages. These results need to be confirmed in a larger series and the value of early treatment should be evaluated.

[Thoracic radiography in detecting heart diseases].

Within the scope of a physical examination, more than 147,000 patients from the Eastern part of France, were examined and had a chest X-ray, between 1982 and 1987. Seven physicians read those radiographs and reported their findings. After discussion of an interindividual variation noted between the seven physicians, the authors present the major findings of this study: relation between a cardiovascular anomaly discovered on the radiographs and a high blood pressure; relation between a cardiovascular anomaly discovered on the radiographs and one or several electrocardiographic anomalies; relation between anomaly of the cardiovascular silhouette as seen on the radiographs and increased levels of triglycerides and cholesterol in young adults.

[Requirements and their realization in thoracic radiography].

Physicians, financial sponsors or administrators, and public opinion make different demands on a working place concerned with chest radiography. The article describes how these demands are translated into reality by present-day equipment setups and systems. In particular, attention is paid on the basis of a slit type radiographic method to present technical possibilities in respect of image quality, dosage and running costs. Modern X-ray systems can produce a high-quality and low-cost X-ray image with an extremely minimal dose that is nearly no longer measurable (3% of the previously employed dose). The image obtained in this manner is of a diagnostic value comparable to that of the conventional large-size X-ray images.

[Diagnostic accuracy of thoracic radiography in infectious pathology].

It is widely recognized that there may be various different reports on the same radiography, because of every single radiologist's subjective interpretation of semiological findings. The authors retrospectively reviewed the X-ray findings of 110 patients (294 chest radiographs) affected by infective pulmonary diseases. A new diagnosis was made, which was compared to the previous one. The quality of each radiograph was judged too, using a grade scale from 0 to 3. The authors confirmed the previous diagnoses in 65.30% of cases. Most of the discrepancies were in case of suspected hilar-mediastinal node involvement, and in case of evident previous pleuropathies. Statistical studies proved the quality of the radiograph not to largely affect the accuracy of the diagnosis in an extemporaneous and discontinuous judgement (P = 0.085).

[Standard thoracic radiography in recent pneumonectomized patients. Its contribution to the diagnosis of empyema and bronchopleural fistula].

Case reports of 110 patients undergoing pneumonectomy were reviewed to assess value of standard postoperative chest radiography for detection of early complications, consisting mainly of empyema and/or bronchopleural fistula. Most radiologic modifications observed do not represent abnormal findings, although two signs can contribute to the radiologic diagnosis of empyema: the central superimposed air/fluid levels and the secondary mediastinal displacement, but even these signs are inconstant and of late onset. Five signs may be of significance for the diagnosis of bronchopleural fistula: in addition to the two described above there are the rapid fall in principal air/water level, the increase in subcutaneous emphysema and the late onset contralateral alveolar syndrome. The diagnosis of a bronchopleural fistula prior to the development of clinical symptoms was possible in one of two cases.

[Digitalized thoracic radiography in cancerology. Present contribution apropos of 200 examinations].

The authors report a double study comparing the conventional chest radiograph and digitalised images. The first study was to visualise normal mediastinal structures (the contour of the posterior mediastinum, the azygo-oesophageal recess, the bronchial sub-segments, intermediate, carina, trachea) and showed a superiority of the digitalised image. The second study was on the recognition of radiological abnormalities in lung cancer which showed no precise superiority of the digitalised image in the mediastinum (bronchial tumour, adenopathies) and a current deficiency at the pleuro-parenchymal level (pulmonary nodules, atelectasis pleural effusion). This double study presents parallel results to those obtained by the anglosaxon authors on different prototypes in whom the technology and possibilities were different. The principles, the advantages and the limits of these prototypes were described and in conclusion a chosen technique for the medium term is proposed by the authors.
