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 (99m)Tc
hexakis-2-methoxyisobutylisonitrile scintigraphy of the neck with the use of
subtraction and two-phase 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.
