[Ga68] DOTATATE PET/MRI-guided radiosurgical treatment planning and response assessment in meningiomas.

Background: Our purpose was to determine the utility of [68Ga]-DOTATATE PET/MRI in meningioma response assessment following radiosurgery.

Methods: Patients with meningioma prospectively underwent postoperative DOTATATE PET/MRI. Co-registered PET and gadolinium-enhanced T1-weighted MRI were employed for radiosurgery planning.

A complete workflow for utilizing Monte Carlo toolkits in clinical cases for a double-scattering proton therapy system.

The methods described in this paper allow end users to utilize Monte Carlo (MC) toolkits for patient-specific dose simulation and perform analysis and plan comparisons for double-scattering proton therapy systems. The authors aim to fill two aspects of this process previously not explicitly published. The first one addresses the modeling of field-specific components in simulation space.

Radiation treatment to a postresection primary mucoepidermoid carcinoma (MEC) of the conjunctiva with positive margins at the Tenon's fascia-A case study.

The primary occurrence of mucoepidermoid carcinoma (MEC) of the conjunctiva is extremely rare, aggressive, and easily mistaken for squamous cell carcinoma. With fewer than 50 cases reported in the literature, there is no consensus on the most effective treatment. Radiation is an alternative to enucleation or orbital exenteration with the potential of eye preservation.
