Technetium 99m Sestamibi in Multiple Myeloma
Radiology, 2005Editor: We read with great interest the excellent review on diagnostic imaging in multiple myeloma by Dr Angtuaco and colleagues in the April 2004 issue of Radiology (1). We would like to address just a few issues related to the use of technetium 99m (Tc) sestamibi.

We report the preliminary results of a prospective study demonstrating tetrofosmin uptake in surgically and histologically proven parathyroid adenomas. In ten patients with primary chronic hyperparathyroidism, parathyroid imaging was performed using (1) technetium-99m methoxyisobutylisonitrile (MIBI) and (2) 99mTc-1, 2-bis(bis(2-ethoxyethyl)phosphino ...

Technetium-99m radiopharmaceuticals
1995Technetium is a group VIIB transition element which has seven electrons beyond the noble gas electronic configuration. The other members of the group are manganese (Mn) and rhenium (Re); together they form a triad (Mn, Tc, Re). All three elements easily lose the seven electrons to yield the +7 oxidation state of permetallate anions (MnO− 4, TcO− 4, ReO−

Comparison of imaging properties of technetium 99m Q12 and technetium 99m Q3 in humans
Journal of Nuclear Cardiology, 1995This study was a direct comparison of the imaging characteristics of 99mTc-labeled Q12 (99mTc-Q12) and 99mTc-labeled Q3 (99mTc-Q3) in the same patients.In 10 patients with known angiographic coronary artery anatomy, 99mTc-Q12 and 99mTc-Q3 myocardial imaging were performed.

Thyroid imaging was performed using technetium-99m methoxyisobutylisonitrile and technetium-99m pertechnetate in 58 patients. The 99mTc-pertechnetate scans showed a total of 77 nodules: 60 cold, 13 hot and 4 of normal activity. There was no 99mTc-MIBI accumulation in 46.4% of 99mTc-pertechnetate cold nodules; 27 (45%) of these nodules showed 99mTc-MIBI

Discordant Uptake of Technetium-99m DISIDA and Technetium-99m Sulfur Colloid in an Amebic Abscess
Clinical Nuclear Medicine, 1988Hepatobiliary imaging in a patient with an amebic abscess showed an early cold defect that later showed rim enhancement. A Tc-99m SC scan did not show prominent flow (making hepatoma unlikely) and showed the previously noted defect to appear larger and without rim enhancement.

Technetium-99m mercaptoalbumin as a potential substitute for technetium-99m labelled red blood cells
European Journal of Nuclear Medicine, 1993Technetium-99m labelled red blood cells (99mTc-RBCs) are far superior to 99mTc-labelled human serum albumin (99mTc-HSA) for radionuclide ventriculography, but their labelling is more complex, time consuming and risk bearing (in vitro labelling) or suffers from interference by some medications (in vivo labelling).

Comparison of technetium 99m-phytate and technetium 99m-sulphur colloid in primary bone tumours
European Journal of Nuclear Medicine, 1990Eleven patients with proven primary bone tumour (five Ewing sarcomas, six osteosarcomas) and two cases of metastatic bone involvement (primary other than bone) were investigated with 99mTc-phytate and 99mTc-sulphur colloid to compare the behaviour of the two radiopharmaceuticals at the tumour site.

Reproducibility of technetium-99m ethylenedicysteine clearance
European Journal of Nuclear Medicine and Molecular Imaging, 1999It has been shown that technetium-99m ethylenedicysteine ((99m)Tc-EC) clearance displays a strong correlation with orthoiodohippurate clearance and that it is possible to estimate effective renal plasma flow from (99m)Tc-EC clearance. However, in routine practice, when monitoring renal function of patients by clearance determinations it is imperative ...
