RADIONUCLIDE PARATHYROID SCINTIGRAPHY WITH 99mTc-SESTAMIBI AND SPECT 

DATE: 11/10/2005

PROCEDURE: Following injection of 99mTc sestamibi and approximately 10 minute delay, anterior projection images of the neck and chest were obtained. After a two-hour delay, repeat anterior projection images of the neck were acquired. SPECT images of the neck and chest were obtained and reconstructed in three axes. 

RADIOPHARMACEUTICAL DOSE: [22] mCi 

CORRELATIVE STUDIES: None. 

COMPARISON: None. 

CLINICAL HISTORY: The patient is a [...]-year-old [fe]male with a history of elevated PTH and calcium who is being evaluated for parathyroid adenoma.

FINDINGS: 

Delayed images demonstrate near complete tracer washout from the thyroid. 

The two-hour delayed images do not demonstrate any focal abnormal persistent uptake in the region of the parathyroid glands to suggest parathyroid adenoma.

On the two-hour delayed images, there is a focus of tracer uptake in the region of the [...] pole, consistent with a parathyroid adenoma. The SPECT images confirm that there is a persistent focus in the inferior neck in the midline. 

There is physiological tracer uptake in the myocardium, liver, salivary glands, and thyroid gland.

There is physiological tracer uptake in the myocardium, liver, salivary glands, and thyroid gland.

CONCLUSIONS: 

Normal parathyroid imaging study. 

Parathyroid adenoma is localized to the [...] pole of the thyroid gland. 

No evidence for mediastinal uptake to suggest mediastinal parathyroid adenoma.

Thank you for referring this patient to the UCLA Nuclear Medicine Clinic.
