Comparative Study
Comparison of Ga-68 DOTA-TATE and Ga-68 DOTA-LAN PET/CT imaging in the same patient group with neuroendocrine tumours: preliminary results.
Recent studies have suggested that PET imaging with Ga-68-labelled DOTA-somatostatin analogues such as octreotide and octreotate is useful in diagnosing neuroendocrine tumours (NETs) and has superior value over both computed tomography and planar and SPECT somatostatin receptor scintigraphy. ⋯ Although the results are preliminary, the image quality obtained by Ga-68-DOTA-TATE seems to be superior to that obtained by Ga-68 DOTA-LAN. With its significantly higher lesion uptake and higher ability to detect lesions, Ga-68-DOTA-TATE seems to be a better radioligand compared with Ga-68-DOTA-LAN for the diagnosis of NETs.
