Correction to: Radiopharmaceutical tracers for cardiac imaging

A lyophilized peptide radiopharmaceutical kit to target neurotensin receptor for tumor imaging

Introduction: Neurotensin (NT) is a tridecapeptide that binds specifically to neurotensin receptors. Several forms of cancer, including small cell lung cancer, colon, pancreatic and prostate carcinomas especially exocrine pancreatic carcinomas express receptors for neurotensin peptide. Radiolabeled neurotensin derivatives with a high affinity for these receptors might be used for scintigraphy. ...

Radiopharmaceutical agents for myocardial perfusion imaging.

Myocardial perfusion imaging (MPI) is a wellestablished noninvasive method of assessing coronary blood flow.1–5 MPI is capable of identifying regional abnormalities in coronary artery blood flow and determining their physiological relevance to myocardial function and viability. MPI requires the intravenous injection of a radioactive blood flow marker followed by imaging of regional myocardial u...

Simulation and patient studies of scatter correction in cardiac SPECT imaging

Introduction: Myocardial perfusion imaging is a nuclear medicine imaging method that is used to detect coronary artery diseases. One of the main sources of error in this imaging method is the detection of Compton scattered photons in the photopeak energy window used for data acquisition. This results in the degradation of the image contrast, and therefore decreases the...

Nuclear tracers for transthyretin cardiac amyloidosis: time to bone up?

Energy window setting for optimum Tl-201 cardiac imaging [Persian]

  Introduction: Poor sensitivity and poor signal to noise ratio because of low injected thallium dose and presence of scattered photons are the main problems in using thallium in scintigraphic imaging of the heart. Scattered photons are the main cause of degrading the contrast and resolution in SPECT imaging that result in error in quantification. Thallium decay is ve...
