Similar changes in blood chemistry were observed following the injection of iohexol and diatrizoate but these changes did not require corrective measures. Significantly more patients complained of a sensation of severe heat after receiving diatrizoate (38%) than after the injection of iohexol (10%) (p = 0.001). Four patients in the diatrizoate group experienced one or more adverse reactions, including mild urticaria. Only mild nausea was reported by a single patient in the iohexol group.

Central arteries and veins can be distinguished on the unenhanced scan by following their course from the hilum on sequential scans, by identifying their relationship to bronchi, or by their vertical or horizontal orientation in the upper and lower lobes. However, arteries cannot be distinguished from veins in the lung periphery. The center of the lung (medulla) harbors \"trunk\" arteries, veins, bronchi and an alveolar meshwork while the periphery (cortex) is characterized by small vessels (1-3 mm) perpendicularly oriented to the pleural surface. Attenuation densities from the right lung at the aortic arch, carina and above the right hemidiaphragm were obtained followed by systematic analysis of various parameters including the mean anterior and posterior cortical and medullary attenuation density, anterior and posterior mean lung density, total mean lung density for each slice and the entire right lung, and the anteroposterior gradients. Different attenuation densities and gradients will be obtained using other models of scanners. The evidence suggests that the medulla is a \"reservoir\" zone, capable of accommodating increased blood flow under appropriate conditions. Clinical application of these parameters to the diagnosis of diffuse lung disease is illustrated.</p>","PeriodicalId":76034,"journal":{"name":"Journal of the Canadian Association of Radiologists","volume":"36 2","pages":"88-102"},"PeriodicalIF":0.0,"publicationDate":"1985-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"15009156","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intermediate: air is visible down to the segmental bronchi. Distal: air is visible down to the subsegmental bronchi or beyond. Proximal or intermediate air bronchograms signify accumulation of secretions in central bronchi and indicate the need for fibreoptic bronchoscopy to aspirate secretions: a distal air bronchogram signifies peripheral bronchial obstruction thus precluding effective fibreoptic bronchoscopy; chest physiotherapy is then a more appropriate treatment.
