IntroductionThe aim of this study was to investigate the value of point shear-wave elastography (pSWE) in the measurement of iron overload in the liver and other visceral organs in patients with beta thalassemia major (BTM).Materials And MethodsThe study included 103 patients diagnosed with BTM who were referred to our clinic for cardiac and liver T2* measurement and a control group of 120 age- and gender-matched healthy volunteers. Cardiac and hepatic T2* measurements were performed in the patient group. Hepatic, pancreatic, splenic, and renal pSWE values were measured in both groups. The pSWE values were compared between the two groups. In the patient group, correlations between pSWE values, cardiac-hepatic T2* values and hepatic size, patient age, and serum ferritin levels were analyzed.ResultsHepatic, pancreatic, splenic, and renal pSWE values were significantly higher in the patient group compared to the control group (p ≤ 0.001, < 0.001, 0.014, 0.026, respectively). In the patient group, hepatic pSWE values established a significant correlation with cardiac T2* values, liver size-T2*, pancreatic pSWE values, serum ferritin levels, and age (p = 0.006, < 0.001, 0.001, 0.042, 0.001, 0.032, respectively). In the ROC analysis, the area under the ROC curve was 0.807 for hepatic pSWE in the discrimination of thalassemia patients and healthy controls, and the cut-off value was 1.42, which gave a sensitivity and specificity of 75.7% and 75%, respectively. CONCLUSıON: Point shear-wave elastography can be a useful technique in the clinical measurement of iron overload in the liver, pancreas, spleen, and kidney.© 2024.
