This article corrects errors in radiopharmaceutical chemical structures for atherosclerosis imaging, including technetium-99m annexin V and gallium-68 DOTATATE, ensuring accurate data presentation.
Area of Science:
- Radiopharmaceutical chemistry and molecular imaging.
- Nuclear medicine and diagnostic imaging techniques.
Context:
- The original article on atherosclerosis imaging contained inaccuracies.
- Specific errors were identified in the chemical structures of key radiopharmaceuticals.
- Table 5 presented incorrect molecular representations for 99mTc annexin V, 68Ga DOTATATE, and 64Cu DOTATATE.
Purpose:
- To provide corrected chemical structures for radiopharmaceuticals used in atherosclerosis imaging.
- To rectify errors in the presentation of 99mTc annexin V, 68Ga DOTATATE, and 64Cu DOTATATE.
- To update the radiopharmaceutical information for Gallium-67 (67Ga) to 67Ga citrate and other listed agents.
Summary:
- Corrected chemical structures for 99mTc annexin V, 68Ga DOTATATE, and 64Cu DOTATATE are provided.
- The radiopharmaceutical for 67Ga has been corrected to 67Ga citrate.
- Multiple radiopharmaceutical entries at the end of the table have been revised for accuracy.
Impact:
- Ensures accurate data for researchers and clinicians in atherosclerosis imaging.
- Improves the reliability of molecular imaging studies utilizing these radiopharmaceuticals.
- Facilitates correct interpretation of imaging results and future research directions.

Cardiac Output II: Effect of Stroke Volume on Cardiac Output
Preload
Preload refers to the initial elongation of the cardiac myocytes before contraction and is related to the volume of blood filling the heart at the end of diastole, or end-diastolic volume. The...
Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
The Cardiac Cycle
The Process
Electrical signals—sent from the sinoatrial (SA) node in the right atrial wall to the atrioventricular (AV) node between the right atrium and right ventricle—cause both atria to simultaneously contract. When the signal reaches the AV node, it pauses for approximately a tenth of a second, allowing the atria to contract and...
