Meningiomas: A Comparative Study of 68Ga-DOTATOC, 68Ga-DOTANOC and 68Ga-DOTATATE for Molecular Imaging in Mice
PURPOSE The goal of this study was to compare the tumor uptake kinetics and diagnostic value of three (68)Ga-DOTA-labeled somatostatin analogues ((68)Ga-DOTATOC, (68)Ga-DOTANOC, and (68)Ga-DOTATATE) using PET/CT in a murine model with subcutaneous meningioma xenografts. METHODS The experiment was performed with 16 male NUDE NU/NU mice bearing xenografts of a human meningioma cell line (CH-157...
متن کاملPineal Parenchymal Tumor of Intermediate Differentiation with Gangliocytic Differentiation
A 49-year-old man presented with an extremely rare case of pineal parenchymal tumor with gangliocytic cells, manifesting as progressive gait disturbance and urinary incontinence lasting for one year. Brain MRI revealed a homogenously enhancing mass, measuring 3.5×2.7 ×1.7 cm, in the pineal body. The mass compressed the deep cerebral vein with superior displacement, which caused mild obstructive...
متن کاملEffective localization in tumor-induced osteomalacia using 68Ga-DOTATOC-PET/CT, venous sampling and 3T-MRI
SUMMARY Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome characterized by renal phosphate wasting leading to hypophosphatemia due to excessive actions of fibroblast growth factor 23 (FGF23) produced by the tumors. Although the best way of curing TIO is complete resection, it is usually difficult to detect the culprit tumors by general radiological modalities owing to the size ...
متن کاملSuccessful Treatment by Chemotherapy of Pineal Parenchymal Tumor with Intermediate Differentiation: A Case Report
A 37-year-old male presented with a mass measuring 2.5 cm in size in the midbrain and obstructive hydrocephalus, which had manifested as a headache and dizziness. Magnetic resonance (MR) imaging of the brain showed intermediate enhancement on T1-weighted MR imaging and a high intensity of enhancement on T2-weighted MR. Neurosurgeons performed an occipital craniotomy with partial removal of the ...
متن کامل[68Ga]-DOTATOC-PET/CT for meningioma IMRT treatment planning
PURPOSE The observation that human meningioma cells strongly express somatostatin receptor (SSTR 2) was the rationale to analyze retrospectively in how far DOTATOC PET/CT is helpful to improve target volume delineation for intensity modulated radiotherapy (IMRT). PATIENTS AND METHODS In 26 consecutive patients with preferentially skull base meningioma, diagnostic magnetic resonance imaging (M...
