[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 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 ...
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 کاملEfficient schemes for robust IMRT treatment planning.
We use robust optimization techniques to formulate an IMRT treatment planning problem in which the dose matrices are uncertain, due to both dose calculation errors and interfraction positional uncertainty of tumour and organs. When the uncertainty is taken into account, the original linear programming formulation becomes a second-order cone program. We describe a novel and efficient approach fo...
