  • Title: Sensitivity of scintigraphy for detection of pulmonary capillary albumin leak in canine oleic acid ARDS.
    Author: Sugerman HJ, Strash AM, Hirsch JI, Glauser FL, Shirazi KK, Sharp DE, Greenfield LJ.
    Journal: J Trauma; 1981 Jul; 21(7):520-7. PubMed ID: 7253049.
    Abstract:
    Computerized gamma scintigraphy was shown in this study to be a sensitive technique for the detection and kinetic analysis of a pulmonary capillary protein leak. A rising lung:heart radioactivity of 'slope of injury' was found at each dose of intravenous oleic acid in dogs from 0.01 to 0.20 ml/kg (p less than 0.01). This 'slope of injury' was proportional to the dose of oleic acid (r = +0.97; p less than 0.004) and was more sensitive than changes in arterial oxygen tension, standard chest radiography, bloodless wet:dry lung weight, or alveolar epithelial membrane permeability. Only standard light microscopy and right lymphatic duct flow were able to document the leakage of protein detected by gamma scintigraphy at 0.01 ml/kg oleic acid.
