α v β 6 Imaging With 68 Ga-Trivehexin PET/CT in Pituitary Macroadenoma

Area of Science:

• Oncology
• Nuclear Medicine
• Radiochemistry

Background:

• The integrin αvβ6 is overexpressed in several epithelial cancers.
• Positron emission tomography/computed tomography (PET/CT) with targeted radiotracers enables in vivo molecular imaging.

Purpose of the Study:

• To evaluate the role of αvβ6 imaging with 68Ga-Trivehexin PET/CT in head and neck, breast, and pancreatic cancers.
• To explore the potential of 68Ga-Trivehexin PET/CT for imaging noncancerous conditions, specifically parathyroid adenoma.

Main Methods:

• Utilized 68Ga-Trivehexin as a positron emission tomography tracer.
• Performed PET/CT imaging to assess αvβ6 expression.

Main Results:

• 68Ga-Trivehexin PET/CT demonstrated potential for imaging head and neck, breast, and pancreatic cancers.
• Preliminary findings suggest applicability in noncancerous conditions like parathyroid adenoma.

Conclusions:

• 68Ga-Trivehexin PET/CT is a promising imaging modality for αvβ6-positive cancers.
• Further research is warranted to establish the role of this imaging technique in noncancerous pathologies.
