[A novel method for quantitative measurement of orbital fat volume based on magnetic resonance images].

Objective: To establish a new method for rapid and quantitative measurement of orbital fat volume based on magnetic resonance imaging (MRI) data.

Methods: We collected MRI data from normalized mold and patients with the diagnosis of thyroid-associated ophthalmopathy (TAO). The cross-sectional areas of the orbital fat on each MR image slice were measured to calculate the fat volume on each slice and then the total orbital fat volume.

[Calculation of orbital fat volumes for determining treatment timing for thyroid- associated ophthalmopathy].

Objective: To analyze the relationship between orbital fat volume and the progression and prognosis of thyroid- associated ophthalmopathy (TAO) and determine the optimal treatment timing for TAO.

Methods: The clinical data were collected from 35 patients (70 orbits) with a definite diagnosis of TAO between January, 2016 and December, 2016. The correlation between orbital fat volume and the clinical parameters was evaluated.
