A medical prescription is required in order to carry out the tests. As these are Nuclear Medicine procedures, the scans involve the administration of a very low-dose radioactive drug, which is eliminated over the following hours via the urine or the digestive tract. Before any scan, the procedure will be explained to you and you will be given a specific information sheet. If you are a woman and are pregnant, think you may be pregnant, or are breastfeeding, please inform the healthcare staff before the scan. Patients who are minors or who require special care must always be accompanied.
Available procedures

CIR-01
Intraoperative sentinel lymph node detection
Description: Assessment of the lymphatic drainage of a neoplasm (melanoma, breast cancer, head and neck, vulvar, cervical, colon or rectal, and thyroid cancer, among others).
Preparation
- Prior to surgery (between 4 and 24 hours beforehand), lymphoscintigraphy with intratumoral or peritumoral injection (or periareolar injection in the case of the breast) must be performed to obtain images of the sentinel lymph node.
Indications
- Intraoperative detection of the sentinel lymph node, the first lymph node draining the lymphatic territory in which an invasive primary tumour is located.
Test duration
The duration of the surgical procedure.

CIR-02 · 03
Sentinel lymph node lymphoscintigraphy / SPECT-CT for sentinel lymph node localisation
Description: Assessment of lymphatic drainage for sentinel lymph node localisation.
Preparation
- No prior preparation is necessary.
- No fasting is required.
Indications
- Localisation of the sentinel lymph node, the first lymph node draining the lymphatic territory in which an invasive primary tumour is located.
Test duration
2 to 3 hours.

CIR-04
Surgical radiolocalisation of tissue (non-sentinel)
Description: Radioguided surgery involves the use of various radiopharmaceuticals administered to the patient before surgery to assist the surgeon during the procedure, by radiolocalising malignant tissue with a probe during the operation.
Preparation
- Varies depending on the condition. Please contact us.
Indications
- Breast cancer (ROLL).
- Hyperparathyroidism surgery (with ⁹⁹ᵐTc-MIBI or ¹⁸F-choline).
- Surgery for differentiated thyroid cancer (DTC) (with ¹³¹I/¹²³I/¹⁸F-FDG).
- Surgery for neuroendocrine tumours (with octreotide/MIBG).
Test duration
Varies depending on the condition.
