TY - JOUR T1 - Human and rabbit lung injuries caused by extreme cold presented by MDCT with perfusion and MRI with diffusion and DWI JF - European Respiratory Journal JO - Eur Respir J VL - 42 IS - Suppl 57 SP - 3025 AU - Aleksandar Ivkovic AU - Tamara Milosavljevic AU - Zoran Radovanovic Y1 - 2013/09/01 UR - http://erj.ersjournals.com/content/42/Suppl_57/3025.abstract N2 - Purpose: purpose is to show effects of extreme cold on lung tissue and to determine role of radiology in diagnostic and proper medical care.Material: We examined 37 patients exposed to extreme cold. There were 24 female and 13 male patients. They were from 18 to 35 years old. All patients were examined on MDCT with perfusion and on 1.5T MRI with DWI. We perform MDCT pulmonary angiography on 16 patients. Also we had a group of 24 rabbits accidentally exposed to extreme cold.Results: MDCT examination was performed in first 24 hour after arriving to hospital care. Additional MDCT angiography was performed in first 72 hours after arriving. MRI was performed 7 days after arriving. We separate results in 3 different subgroups according to patient’s conditions. First subgroup was patients with bronchiolitis of lower parts of lung with no other signs. Second subgroup was patients with bronchiolitis of all parts of lung. Third subgroup was patients with hard symptoms, all in intensive care unit. Radiology findings were from edema and reactive pneumonia to hematopneumotorax. On MDCT angiography we find thromboembolism of lower lung vessels. MDCT perfusion and MRI DWI were performed to determine borders and levels of injuries. Hyperpnoea of temperate air shares similar effects to the inhalation of cold air. Hyperpnoea of cold air may cause the ASL to evaporate more rapidly than it can be replaced. We compare results with rabbit exposed to extreme cold.Conclusion: Extreme cold can make serious injuries to lung tissue. MDCT examination has a great role in diagnostic and follows up. MDCT perfusion and MRI DWI give us information about exact border of injuries and prognosis. ER -
