Abstract

Objective: To compare the fractal analysis data of ultrasonography (USG) images of the submandibular and parotid glands before and after parenchymal stimulation to assess for any changes.

Methods: The study was conducted by taking 240 USG images of bilateral parotid and submandibular glands of 30 patients before and after stimulation. Patients chewed gum for stimulating their salivary glands. Fractal analysis was performed on the USG images, and the data obtained were statistically compared.

Results: The fractal analysis value of the USG images of the parotid gland was 1.45, both before and after stimulation, indicating no statistically significant difference (p = 0.866). In the submandibular gland, this value was the same before and after stimulation (fractal analysis = 1.42), showing no statistically significant difference (p = 0.748). Parotid and submandibular glands were compared. USG fractal analysis values before and after stimulation and the overall values were statistically significantly different between the different salivary glands (p < 0.05).

Conclusion: According to fractal analysis, there was no change in the parenchyma of the submandibular and parotid glands despite the stimulation. Submandibular and parotid glands could be distinguished by fractal analysis.

超声图像分形分析刺激与非刺激唾液腺实质的比较。

目的：比较颌下腺和腮腺实质刺激前后超声图像的分形分析数据，评价其变化。方法：对30例患者进行刺激前后双侧腮腺和下颌下腺的超声成像240张。病人嚼口香糖是为了刺激他们的唾液腺。对USG图像进行分形分析，并对所得数据进行统计比较。结果：刺激前后腮腺USG图像分形分析值为1.45，差异无统计学意义（p = 0.866）。在颌下腺中，刺激前后该值相同（分形分析= 1.42），差异无统计学意义（p = 0.748）。腮腺和下颌腺比较。不同唾液腺刺激前后的USG分形分析值及总体值差异均有统计学意义(p)。结论：根据分形分析，刺激后颌下腺和腮腺实质组织无明显变化。分形分析可以区分下颌腺和腮腺。

期刊介绍： As the official English-language journal of the Japanese Society for Oral and Maxillofacial Radiology and the Asian Academy of Oral and Maxillofacial Radiology, Oral Radiology is intended to be a forum for international collaboration in head and neck diagnostic imaging and all related fields. Oral Radiology features cutting-edge research papers, review articles, case reports, and technical notes from both the clinical and experimental fields. As membership in the Society is not a prerequisite, contributions are welcome from researchers and clinicians worldwide.
