Abstract:
Objective:To investigate the sensitivities and specificities of high-frequency color doppler ultrasonography, thin layer CT enhancing scan and 99m Tc-MIBI biphasic scintigraphy in diagnosis of secondary hyperparathyroidism(SHPT)in uremia patients.Methods: High-frequency color doppler ultrasonography, thin layer CT enhancing scan and 99m Tc-MIBI biphasic scintigraphy were performed in 35 uric patients to detect the hyperplastic parathyroid glands. Then biopsies with thin needles were conducted with B ultrasound instruction in hyperplastic glands to determine the sensitivities and specificities of the above techniques and free combination of each 2 of them in diagnosis of SHPT. Results: The sensitivities /specificities of high-frequency color doppler ultrasonography, thin layer CT enhancing scan and 99m Tc-MIBI biphasic scintigraphy were 73%/95%, 75%/93% and 89%/98%, respectively; the sensitivity/specificity of 4 combinations: high-frequency color doppler ultrasonography plus CT, high-frequency color doppler ultrasonography plus 99m Tc-MIBI biphasic scintigraphy, CT plus 99m Tc-MIBI biphasic scintigraphy,and high-frequency color doppler ultrasonography plus CT plus 99m Tc-MIBI biphasic scintigraphy were 84%/90%, 93%/93%, 95%/93%, and 100%/90%, respectively. Conclusion: The sensitivity of 99m Tc-MIBI biphasic scintigraphy SHPT is higher than that of high-frequency color doppler ultrasonography and CT, but the specificity is not significantly different 3 photographic techniques. However, combination of high-frequency color doppler ultrasonography and 99m Tc-MIBI biphasic scintigraphy is simple and sensitive and can be regarded as the first choice for diagnosis of SHPT in uremia patients.
