[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...
متن کامل68Ga-DOTA-D Phe1-Tyr3-Octreotide (DOTATOC)-PET/CT in a Suspected Case of Recurrent Meningioma
We present a case of 45-year-old female who presented with headache for last 1 month. She was a follow-up case of left frontal meningioma that was operated 4 years back. CEMRI of the brain suggested post-surgical changes with no obvious enhancing residual/recurrent lesion. The patient was then referred for 68 Ga DOTANOC PET/CT to rule out recurrent disease. PET/CT revealed a focus of somatostat...
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 کامل68Ga-DOTATOC PET/CT in Patients with Iodine- and 18F-FDG-Negative Differentiated Thyroid Carcinoma and Elevated Serum Thyroglobulin.
This study evaluated the impact of 68Ga-DOTATOC PET/CT in detecting recurrence or metastases in differentiated thyroid carcinoma (DTC) patients with elevated serum thyroglobulin and both negative radioiodine imaging and negative 18F-FDG PET/CT. METHODS 68Ga-DOTATOC PET/CT (CT without contrast, low-dose) was performed on average 6 wk after negative 18F-FDG PET/CT (CT contrast-enhanced, full-do...
متن کاملInfluence of 68Ga-DOTATOC on sparing of normal tissue for radiation therapy of skull base meningioma: differential impact of photon and proton radiotherapy
BACKGROUND To evaluate the impact of 68Ga-DOTATOC-PET on treatment planning and sparing of normal tissue in the treatment of skull base meningioma with advanced photons and protons. METHODS From the institutional database consisting of 507 skull base meningiomas 10 patients were chosen randomly for the present analysis. Target volume definition was performed based on CT and MRI only, as well ...
