Cardiac Imaging Agents

Imaging Protocols

• Sestamibi shows a linear relationship with coronary blood flow when administered intravenously, making it effective for detecting areas of reduced perfusion, and has limited redistribution over time, allowing delayed imaging after injection without significant change in the initial distribution pattern, according to the European Heart Journal 1
• The American College of Radiology recommends that Sestamibi imaging typically takes approximately 40 minutes for image acquisition 2
• The American College of Cardiology states that the typical effective dose range for a 1-day Tc-99m rest-stress imaging protocol is 9.8 to 16.3 mSv 3
• Studies have shown high sensitivity (93%) and specificity (70%) for detecting myocardial infarction using Sestamibi SPECT imaging, as reported in the European Heart Journal 4
