ENDOCRINOLOGY PROCEDURES
It is mandatory to present your medical prescription to be able to carry out the tests.
If you are a pregnant woman or if you suspect that you may be so, or if you are breast-feeding,
please notify it to our health staff before performing any test.
All nuclear medicine tests involve the administration of a radiopharmaceutical
with a very low dose of radioactivity, which is eliminated in the following hours through the urinary or digestive routes.
The access of companions to the center is allowed in the case of children and patients who require special attention.
The rest of the patients can come accompanied but, as a health precaution during the pandemic and depending on
the capacity of the waiting room and the criteria of our staff, it is possible that
the companion cannot wait inside the center.

DESCRIPTION: Evaluation of iodine effective mean time in the thyroid gland. Determination of thyroid uptake both total and in 6 regions of interest.
PREPARATION: The patient must not be in a situation of iodic saturation, either because of intravenous or intrathecal scans with iodized contrast (pyelography, CAT scan with contrast, myelography and some angiographies) at least 3 weeks before the procedure or because of treatment with Amiodarone at least 6 months before it. If possible, the patient should not be having antithyroid medication (propylthiouracil (PTU) and tapazole) for at least 3 days before the procedure. Other isotopic explorations must be avoided during the procedure.
INDICATIONS: Dosimetric calculation of 131I dose for hyperthyroidism.
DURATION OF PROCEDURE: 1 hour.
DESCRIPTION: Localization of the parathyroid glands.
PREPARATION: No preparation is required. It is recommended that the patient has not received studies with iodine contrasts at least 3 weeks before the procedure. While the images are being taken, the patient should not move his/her neck and must nor swallow saliva, and if necessary, should be immobilized with sandbags.
INDICATIONS: Detection and localization of adenomas and hyperplasias of parathyroid glands. Evaluation of the status of parathyroid glands within hypercalcemia and hyperparathyroid disorders. Detection of ectopic parathyroid glands.
DURATION OF PROCEDURE: 3 hours.
SUPRARENAL CORTEX SCINTIGRAPHY
(WITH OR WITHOUT STOPPING)
DESCRIPTION: Functional evaluation of the suprarenal glands’ cortex (nor-cholesterol follows the metabolic pathway of adrenal steroids).
PREPARATION: As a prevention, the thyroid gland must be blocked with 20 drops/3 times per day of potassium iodide, starting 5 days before the administration of the dose and extending until 3 days after the procedure is finished. Some medications can produce pharmacological interaction with nor-cholesterol and it is advisable to remove them during the procedure:
- Tricyclic Antidepressants (Amitriptyline, Imipramine).
- Sympathomimetics (Phenylephrine, Phenylpropanolamine, Pseudoefrin, Ephedrine).
- Antihypertensives/cardiovascular drugs (Labetalol, Reserpine, Ca-channel blockers).
In case of hyperaldosteronism, the gland must be stopped with 4 mg/day of dexamethasone (fortecortin 1 1 mg-comprimit/6 hours) from 7 days before the administration of nor-cholesterol, and until the end of the imaging session. Withdrawal should be progressive (progressive dose reduction in 5 days). Contraindications of stopping are those of corticoids: bleeding, alterations of the coagulation, gastroduodenal ulcers, glaucoma. The acquisition of images is performed on the 2nd and 4th day (always before the 5th day).
INDICATIONS: Diagnosis of the adrenal cortex pathology: localization of adenoma/adrenal hyperplasia, diagnosis of Cushing syndrome of adrenal origin, the differential diagnosis between adenoma and adrenal hyperplasia (Conn), study of adrenal masses seen with other imaging techniques (TAC, NMR, ECO): incidentalomas.
DURATION OF PROCEDURE: 7 days.

THYROID SCINTIGRAPHY
DESCRIPTION: Evaluation of the morphology and functionality of the thyroid gland.
PREPARATION: No fasting is required. A brief and specific recollection of information that includes thyroid palpation should be performed. Thyroid substitute medications should be removed in patients taking thyroid replacement therapy (children diagnosed with neonatal hypothyroidism, others), and in order to visualize the thyroid gland (thyroxin [T4] for at least 7 days before the scan, triiodothyronine [T3] for at least 3 days before the scan). The patient must not be in a situation of iodic saturation, either because of intravenous or intrathecal scans with iodized contrast (pyelography, CAT scan with contrast, myelography and some angiographies) at least 3 weeks before the procedure or because of treatment with Amiodarone at least 6 months before it.
INDICATIONS: Morphological evaluation of the thyroid gland. Thyroid location and evaluation of thyroid ectopies. Study of goiter, endothoracic goiter and thyroid nodules. Diagnosis of subacute thyroiditis. Evaluation of thyroid post-surgical remnants.
DURATION OF PROCEDURE: 30 minutes.

If hormonal suppression is not advised, TSH can be stimulated with two intramuscular injections in two consecutive days of rhTSH (Thyrogen). The patient must not be in iodic saturation, either because of intravenous or intrathecal scans with iodized contrast (skinography, TAC with contrast, myelography and some angiographies) at least 3 weeks before the procedure, or because of treatment with amniodarone at least 6 months before the procedure.
