“…GKRS for TN involves a series of steps, including frame fixation, image acquisition and registration, treatment planning, and gamma radiation exposure. Computed tomography (CT) and magnetic resonance imaging (MRI) are used during the image acquisition and registration phases [ 7 , 8 ]. For GKRS of the TN, it is crucial to ascertain the precise location of the trigeminal nerve, where MRI, in particular, provides the necessary positional information for accurate targeting, thereby enabling safer surgical procedures [ 6 ].…”

This study aimed to implement a deep learning-based super-resolution (SR) technique that can assist in the diagnosis and surgery of trigeminal neuralgia (TN) using magnetic resonance imaging (MRI). Experimental methods applied SR to MRI data examined using five techniques, including T2-weighted imaging (T2WI), T1-weighted imaging (T1WI), contrast-enhancement T1WI (CE-T1WI), T2WI turbo spin–echo series volume isotropic turbo spin–echo acquisition (VISTA), and proton density (PD), in patients diagnosed with TN. The image quality was evaluated using the peak signal-to-noise ratio (PSNR) and structural similarity index (SSIM). High-quality reconstructed MRI images were assessed using the Leksell coordinate system in gamma knife radiosurgery (GKRS). The results showed that the PSNR and SSIM values achieved by SR were higher than those obtained by image postprocessing techniques, and the coordinates of the images reconstructed in the gamma plan showed no differences from those of the original images. Consequently, SR demonstrated remarkable effects in improving the image quality without discrepancies in the coordinate system, confirming its potential as a useful tool for the diagnosis and surgery of TN.
