Tips for anemia on unenhanced computed tomography of the thorax in the elderly: Subjective and objective assessment


Author(s): Mehmet Akçiçek, Mehtap Ilgar and Serkan Ünlü

Abstract: Objective: To obtain information on whether blood attenuation values are correlated with hemoglobin levels, besides visualization of the interventricular septum and aortic wall signs, in this way providing to estimate the severity of anemia in the elderly.
Subjects and Methods: 169 patients over 65 years old who applied for various reasons in the first three months of 2019 were selected for this study if they had undergone unenhanced thorax CT and their hemoglobin levels had been assessed within 24 hours. Radiologists identified the presence or absence of the interventricular septum and aortic ring signs. Blood density was measured as ROIs. One each ROIs were placed on the left ventricular cavity, the aortic arc, also on the pulmonary arteries, the ascending and descending aortas.
Results: All statistical analysis was performed with the SPSS 22. The specificity was calculated as 100% for IVS, the sensitivity was 57.1%. These values were 51.7% and 91.8%, respectively, for the AR. The correlation between hemoglobin values and blood densities was evaluated by pearson correlation analysis and there was a strong correlation. The cut off HU value for aorta was 36.4, with 69.4 sensitivity and 88.3 specificity. The cut off HU value for the pulmonary artery was 35.2, with 61.2 sensitivity and 87.5 specificity. The cut off HU value for the left ventricle was 37.6, with 77.5 sensitivity and 75.8 specificity.
Conclusion: Interpretation of an anemic situation on the unenhanced thorax CT of the elderly by making subjective and objective assessments will guide the clinician.
