Summary
Technetium Tc 99m MIBI scintigraphy demonstrated high accuracy in diagnosing thyroid carcinoma, outperforming technetium Tc 99m pertechnetate. This imaging technique can aid in pre-operative evaluation when combined with fine needle aspiration.
Area of Science:
- Nuclear Medicine
- Oncology
- Radiology
Background:
- Well-differentiated thyroid carcinoma requires accurate pre-operative diagnosis.
- Distinguishing malignant from benign thyroid nodules is crucial for appropriate patient management.
Purpose of the Study:
- To evaluate the diagnostic performance of Technetium Tc 99m MIBI (MIBI) thyroid scintigraphy.
- To compare MIBI scintigraphy with Technetium Tc 99m pertechnetate scintigraphy in patients with suspected thyroid carcinoma.
Main Methods:
- A cross-sectional descriptive study was conducted.
- 63 patients with thyroid nodules underwent fine needle aspiration, thyroid function tests, and both MIBI and pertechnetate scintigraphy.
- Results were compared with post-operative histopathology.
Main Results:
- MIBI scintigraphy correctly identified malignancy in 21 out of 22 malignant cases (95% sensitivity).
- MIBI showed a specificity of 63% for malignancy.
- Technetium Tc 99m pertechnetate had lower sensitivity (77%) and specificity (29%).
Conclusions:
- Technetium Tc 99m MIBI scintigraphy is a valuable tool for pre-operative assessment of thyroid nodules.
- MIBI scintigraphy, in conjunction with fine needle aspiration, improves diagnostic accuracy for thyroid carcinoma.

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body being...
