ABSTRACT
Objective To evaluate the diagnostic value of three nuclide imaging methods in patients with hyperparathyroidism. Methods Thirty five patients with hyperparathyroidism underwent 201 Tl/ 99m TcO-4 (8 cases), double phase 99m Tc MIBI imaging methods (27 cases) and 99m Tc MIBI/ 99m TcO-4 substraction imaging (20 cases). Abnormal increase of radioactivity in substraction imaging or delay imaging denoted positive result. All data of nuclide imaging were evaluated according to final clinical results and were compared with ultrasound or CT. Results 35 cases of hyperparathyroidism were proved, including 31 adenomas (ectopic 1), 3 hyperplasia and 1 carcinoma. The sensitivity of 201 Tl/ 99m TcO-4 , double phase 99m Tc MIBI imaging and 99m Tc MIBI/ 99m TcO-4 substraction imaging was 62.5%, 88.9%,90.0%, respectively. The specificity of 3 nuclide imaging methods was 100%. The sensitivity and specificity of ultrasound were 74.3%, 85.7%, respectively. The sensitivity of CT was 78.6%. The results showed that 99m Tc MIBI/ 99m TcO-4 was superior to other imaging. Conclusion An accurate diagnosis of hyperparathyroidism and preoperative anatomic localization can be determined by means of nuclide imaging.
