Objectives: Transient ischemic dilatation (TID) in myocardial perfusion single photon emission computed tomography (SPECT) is considered a marker of poor prognosis. However, it has been suggested that some cases are due to apparent volumetric changes secondary to differences in heart rate (HR) at the time of acquisition. We assessed the correlation between transient dilatation and HR in low risk patients with no perfusion defects.

Article Synopsis
  • Cardiovascular diseases (CVDs) are the leading cause of death in Latin America and the Caribbean, with men being slightly more at risk than women, and COVID-19 has negatively impacted cardiac diagnostics in the region.
  • The availability of nuclear cardiology differs across LAC, with Argentina and Brazil having the most scanning technologies, including SPECT and PET, and advancements like CZT gamma cameras being introduced.
  • Challenges to developing nuclear cardiology include high costs, maintenance issues, lack of training for healthcare professionals, and the need for collaboration among specialists to enhance the use of imaging modalities.

Background: There is paucity of data on left ventricular (LV) functional parameters using gated SPECT myocardial perfusion imaging (MPI) from the Latin American region. This study provides detailed information in low-risk patients both at rest and during exercise.

Methods And Results: We studied 90 patients (50 men) with a very low likelihood of coronary artery disease.

Introduction: It has been demonstrated that scintigraphy with somatostatin analogues is useful for the diagnosis, staging and follow up of patients with neuroendocrine tumors from the gastrointestinal tract (NET-GIT). Some studies suggest that the use of 99mTc-Hydrazinonicotinyl-Tyr3-octreotide (99mTc-HYNIC-TOC) yields similar diagnostic results than the use of 111In-DTPA-octreotide.

Objective: To determine the clinical value of scintigraphy using 99mTc-HYNIC-TOC for the detection of primary and secondary lesions in patients with NET-GIT.
