Contrast-enhanced CT for attenuation correction in ultra-high sensitivity long-axial field-of-view lymphoma PET: amplified quantification problems?

Key Points

• The aim is to evaluate the impact of CE-CT on SUV measurements in LAFOV-PET for lymphoma.
• Utilized CE-CT for attenuation correction in LAFOV-PET imaging.
• Assessed SUV measurements in lymphoma lesions under ultra-high sensitivity mode.
• Compared findings with conventional standard axial field-of-view PETs.
• Observed higher SUV measurements in lymphoma lesions using CE-CT.
• Noted increased quantification problems compared to standard axial PET.
• Highlighted the need for careful interpretation of borderline cases.
