| Summary: | Background: The imaging techniques most commonly used in the diagnosis of hyperparathyroidisms
are ultrasound and scintigraphy. The diagnostic algorithms vary, depending mainly on the population, and experience of physicians. Aim: Aim of the present research
was to determine the usefulness of parathyroid scintigraphy and ultrasonography in patients
diagnosed for hyperparathyroidism in own material. Material and method: In the
present research, 96 operated patients with documented primary, secondary and tertiary
hyperparathyroidism were retrospectively analyzed. All patients underwent a 99mTc hexakis-
2-methoxyisobutylisonitrile scintigraphy of the neck with the use of subtraction and twophase
examinations. Ultrasonography of the neck was performed in all the patients in B
mode 2D presentation. A total number of 172 parathyroid glands were analyzed. Results:
The sensitivity and specificity of scintigraphy was 68% and 60%, respectively. The sensitivity
of ultrasound was 49% and specificity 85%. Both techniques allowed visualization of 76
parathyroid glands. Ultrasound revealed 19 glands that were not visible in scintigraphy.
Scintigraphy showed 76 parathyroid glands that were not visualized on ultrasound. Having
combined the results of scintigraphy and ultrasound, the sensitivity of 76% and specificity
of 50% were obtained. Considering the ability to locate the parathyroid glands in both
techniques as a positive result, the sensitivity decreased to 37% and specificity rose to 95%.
Conclusions: Scintigraphy showed greater sensitivity than ultrasound in the localization of
enlarged parathyroid glands. Ultrasound, in turn, was characterized by a higher specificity.
The combined use of scintigraphy and ultrasonography allowed to obtain the specificity of
95%. In the light of obtained results, scintigraphy and ultrasonography are complementary
and should be used together. |
