ABSTRACT
Background:
The planum temporale (PT) is well known for its classic “pie-shaped” morphology. The aim of this study is to create a taxonomy of PT morphological features to improve its sometimes difficult identification and differentiation from surrounding structures.
Material and methods:
A total of 50 normal, high-resolution T1-weighted brain MRIs (100 hemispheres) were obtained from the Open Access Series of Imaging Studies (OASIS) repository. Ages ranged from 18 to 57 years.
Methods:
A 3D cortical surface mesh (grey matter) was generated using neuroimaging software. The PT was isolated based on pre-defined criteria and stratified into different classifications. Quantitative measurements were also taken.
Results:
A total of four PT configurations were identified: (1) Pie-shaped [45%], 508.8 mm2; (2) Trapezoid-shaped [27%], 540.4 mm2, (3) Rectangular-shaped [19%], 477.7 mm2; and (4) Amorphous/none [9%], not calculable. The trapezoid-shaped PT category occurred significantly more often in females.
Conclusions:
The proposed classification is the first step in creating a comprehensive.
