Ohkubo M, Higaki T, Nishikawa K, Otonari-Yamamoto M, Sugiyama T, Ishida R, et al.
Bull Tokyo Dent Coll . 2014 Sep; 55(3):131-7. PMID: 25212558
Videofluorography is frequently used to evaluate swallowing and is considered the "gold standard" among imaging modalities. This modality, however, has several disadvantages, including radiation exposure and limitations in the detection...

Sasaki Y, Sakamoto J, Otonari-Yamamoto M, Nishikawa K, Sano T
Oral Surg Oral Med Oral Pathol Oral Radiol . 2013 Sep; 116(4):503-10. PMID: 24035116
Objective: To determine the potential of fluid-attenuated inversion recovery (FLAIR) imaging of oral and maxillofacial vascular malformations as an alternative to contrast-enhanced magnetic resonance imaging (MRI), we investigated the influence...

Aizawa M, Nishikawa K, Sasaki K, Kobayashi N, Yama M, Sano T, et al.
Nihon Hoshasen Gijutsu Gakkai Zasshi . 2012 Jan; 68(1):30-9. PMID: 22277813
Development of multi-detector row computed tomography (MDCT) has enabled three-dimensions (3D) scanning with minute voxels. Minute voxels improve spatial resolution of CT images. At the same time, however, they increase...
