• initial studies have shown good concordance between 201Tl and 99mTc-sestamibi activities in both viable and nonviable myocardium. (ac.ir)
  • However, assessment of myocardial viability by 99mTc-sestamibi remains controversial for tissue recovery after revascularization. (ac.ir)
  • This may highlight the failure of 99mTc-sestamibi as a marker of myocardial viability and also mandate further validating of the procedure with follow up scan or other modalities for myocardial viability investigation. (ac.ir)
  • Compared with 201Tl, 99mTc sestamibi does not significantly redistribute. (biomedsearch.com)
  • Imaging tests that have shown particular promise for this application include 124I-girentuximab PET/CT for diagnosing clear cell renal cell carcinoma and 99mTc-sestamibi SPECT/CT for diagnosing renal oncocytomas and hybrid oncocytic/chromophobe tumors.SummaryMolecular imaging offers a noninvasive means of determining the histology of renal tumors thereby aiding in the risk stratification of patients presenting with a renal mass.

  • Breast‐specific gamma imaging with 99mTc‐Sestamibi and magnetic resonance imaging in the diagnosis of breast cancer-a comparative study. (healthpartners.com)
  • The potential diagnostic value of intracoronary sestamibi at the time of coronary angiography deserves to be validated as a possible alternative to other current procedures for detecting hibernating myocardium. (semanticscholar.org)
  • Characterization of the neoplastic potential of solitary solid thyroid lesions with Tc-99m-pertechnetate and Tc-99m-sestamibi scanning. (nih.gov)
  • Consecutive unselected patients were studied either with sestamibi or with tetrofosmin on a random basis, until at least 100 patients had been enrolled for each gender and tracer. (biomedsearch.com)
  • Four patient groups were analysed: males with sestamibi or tetrofosmin (MS: n = 189 and MT: n = 157), females with sestamibi or tetrofosmin (FS: n = 101 and FT: n = 104). (biomedsearch.com)
  • No gender-specific effect was found for Mean, so the overall mean gain was calculated for Mean: +13% for sestamibi vs tetrofosmin. (biomedsearch.com)
  • In summary, we found significantly higher myocardial counts with sestamibi than with tetrofosmin, in males as well as in females. (biomedsearch.com)
  • A principal change in the acquisition parameters compared with previous Tc-99m sestamibi protocols is the use of a high-resolution collimator. (nih.gov)
  • The utilization of Tc-99m would allow higher doses (up to 1,100 MBq or 30 mCi) due to the shorter physical (6 hours) half life of Tc-99m. (wikipedia.org)
