Parathyroid scintigraphy with 99mTc-sestamibi (MIBI) is an established technique for localising abnormal parathyroid glands (PGs). However, the identification and localisation of PGs require much attention from medical experts are time-consuming. Artificial intelligence methods can offer assisting solution. This retrospective study enrolled 632 patients who underwent double-phase thyroid subtra...

(99m)Tc-Tetrofosmin ((99m)Tc-TF) and (99m)Tc-Sestamibi ((99m)Tc-MIBI) are SPECT tracers that have been used for brain tumor imaging. Tumor's multidrug resistance phenotype, namely, P-glycoprotein (p-gp), and the multidrug resistance related proteins (MRPs) expression have been suggested to influence both tracers' uptake. In the present study we set out to compare (99m)Tc-TF and (99m)Tc-MIBI upt...

Introducción y objetivo: La medicina Nuclear, desde sus inicios, ha tenido un papel importante en el estudio tratamiento de la patología tiroidea.

En actualidad, desarrollo nuevas técnicas como son ecografía alta resolución punción por aspiración con aguja fina originado avance diagnóstico manejo ésta patología....

PURPOSE To determine if there was any difference in the ability of physicians to predict prognosis with technetium 99m ((99m)Tc) sestamibi or (99m)Tc tetrofosmin in a large consecutive series of patients at high risk for coronary artery disease who underwent coronary angiography. MATERIALS AND METHODS This study included 1,818 consecutive patients who underwent a rest and stress single photon...
