Clinical usefulness of 99mTc-MIBI scintigraphy in the postsurgical evaluation of patients with differentiated thyroid cancer.
OBJECTIVE Tc-methoxyisobutyl isonitrile (MIBI) has been reported to show considerable clinical utility in the study of many neoplastic diseases. The aim of our study was to investigate the possible role of Tc-MIBI in the initial follow-up of patients with differentiated thyroid cancer (DTC) for detecting residual thyroid uptake and/or loco-regional/distant metastases. METHODS Eighty-two patie...
متن کامل99mTc-HYNIC-TOC scintigraphy is superior to 131I-MIBG imaging in the evaluation of extraadrenal pheochromocytoma.
UNLABELLED In this investigation, the efficacy of scintigraphy using (99m)Tc-labeled hydrazinonicotinyl-Tyr3-octreotide (HYNIC-TOC) in the evaluation of extraadrenal pheochromocytoma was assessed and compared with (131)I-labeled metaiodobenzylguanidine (MIBG) imaging. METHODS Ninety-seven patients who were suspected of having pheochromocytoma but showed no definite adrenal abnormalities on CT...
متن کاملReproducibility of renal length measurements with 99mTc-DMSA SPECT.
UNLABELLED Renal length measurements are used in evaluating several abnormalities of the pediatric genitourinary tract. This study assesses reproducibility of renal length measurements obtained with 99mTc-dimercaptosuccinic acid (DMSA) SPECT. METHODS The lengths of 98 kidneys of 51 children (age range, 1-16 y; mean age, 5.4 y) who underwent 99mTc-DMSA SPECT were measured independently by 2 ob...
متن کاملThe value of the Gated 99mTc-MIBI SPECT in differentiation of fixed myocardial lesions [Persian]
Fixed myocardial defects in both stress and rest images, could be artifactual as a result of soft tissue attenuation. To increase specificity and identify the false positive results, we used gated technique to evaluate the wall motion and wall thickening as an index to differentiate real ischemic lesions from artifactual defects. 93 patients were studied. In 46 patients (48.8%) fixed perf...
متن کاملIn vivo assay of folate receptors in nonfunctional pituitary adenomas with 99mTc-folate SPECT/CT.
UNLABELLED The objective of this study was to evaluate the in vivo assay of folate receptors in nonfunctional pituitary adenomas using preoperative (99m)Tc-folate SPECT/CT and Western blot analysis (WBA) of surgical specimens as the standard. METHODS Fifty-six patients (29 men, 27 women; age range, 29-82 y) with clinically nonfunctional pituitary adenomas on MRI underwent preoperative imaging...
