Introduction: Introduction: Anaemia is a widespread problem and although Computed Tomography (CT) is not the primary modality to diagnose anaemia as it is possible to easily obtain the haemoglobin estimation levels, which is a direct measure for the degree of anaemia. However, it is possible to detect certain changes on CT that point towards anaemia. It is important to identify incidental findings as it can have a direct effect on the management and outcome.
Aim: The aim of the present was to evaluate the role and accuracy of unenhanced CT thorax in prediction of anaemia.
Materials and Methods: This was a cross-sectional study on a total of 100 cases. All the patients who underwent thoracic/abdominal CT in Department of Radiodiagnosis and Imaging in Father Muller Medical College and Hospital, Kankanady, Manglore, India were included as subjects from July 2019 to September 2019. The normal reference blood haemoglobin level was taken as 14 g/dL and 11 g/dL in the male and the female population respectively. The peripheral blood examination was done within 24 hours after or before an unenhanced CT scan. Sixteen slice CT scanner was used for the study. Frequency, percentage, mean, Standard Deviation (SD), Positive Predictive Value (PPV), Negative Predictive Value (NPV) was used in statistical analysis of data. Chi-square/Fisher’s Exact test was used and p-value <0.05 is considered to be significant.
Results: This was a female predominant study consisting of 53 females of sample size. A total of 59% patients were diagnosed to have anaemia by blood parameters. A total of 61% patients were detected to have the aortic ring sign whereas 65% of the patients were detected with hyperdense Interventricular (IV) septum sign.
Conclusion: Whenever the interventricular septum is seen on a CT thorax without contrast, it suggests the presence of underlying anaemia and it needs to be evaluated so as to improve the management and reduce the morbidity to the patient.
