Summary
Three-dimensional surface renderings improve the morphometry of the supratemporal cortex, specifically the planum temporale. This method offers enhanced reliability and validity for studying brain asymmetry.
Area of Science:
- Neuroimaging
- Neuroanatomy
- Computational anatomy
Background:
- Cortical surface rendering methodologies enable quantitative morphometry.
- The planum temporale is a neuroanatomical structure known for its asymmetry.
Purpose of the Study:
- To investigate the application of 3D surface renderings for quantitative morphometry of the planum temporale.
- To assess the reliability and validity of surface renderings in studying cortical asymmetry.
Main Methods:
- Analysis of the planum temporale area using 3D surface renderings of the supratemporal cortex.
- Study conducted on volume MRIs of seven normal, right-handed males.
Main Results:
- Surface renderings provided greater interrater reliability compared to conventional MRI section measurements.
- Results showed more consistent evidence of expected planum temporale asymmetry.
Conclusions:
- 3D surface renderings enhance supratemporal cortex morphometry.
- Surface rendering techniques show promise for studying other cortical regions.
