[Impact of Differences in Radiopharmaceuticals on Brain Perfusion SPECT Phantom Examination Using the Hoffman 3D...

Area of Science:

• Nuclear Medicine
• Radiopharmaceutical Science

Context:

• The Hoffman phantom is crucial for quality control in nuclear medicine imaging.
• Accurate radiopharmaceutical distribution is essential for reliable SPECT/CT analysis.

Purpose:

• To evaluate the influence of radiopharmaceuticals and buffer solutions on Hoffman phantom examination accuracy.
• To determine if buffer solutions are necessary for optimal SPECT/CT image quality.

Summary:

• Different solutions (¹²³I-MIBG, ¹²³I-IMP, ¹²³I-IMP with buffer) were tested in a Hoffman phantom.
• SPECT/CT imaging assessed radiopharmaceutical distribution and left-right ratios at various stirring times.
• No significant differences in image quality were found after 20 minutes of stirring, irrespective of buffer use.

Impact:

• Findings suggest that thorough agitation is sufficient for accurate SPECT/CT imaging with the Hoffman phantom.
• This research may streamline phantom preparation protocols by potentially eliminating the need for buffer solutions.
• Optimized phantom preparation can enhance the reliability of nuclear medicine diagnostic procedures.
