摘要

目的:近年来,SPECT/CT已被广泛接受为一种有价值的牙科诊断工具。本研究的目的是通过CT和SPECT/CT研究颌下腺涎石症,特别是CT值,标准化摄取值(suv)和腮腺和颌下腺的唾液腺排泄。方法:对13例接受CT和唾液腺SPECT/CT检查的下颌下涎石症患者进行前瞻性研究。利用工作站和软件获取腮腺和颌下腺的CT值和suv。腮腺和下颌下腺的唾液腺分泌量定义为suv刺激前后的比值。p值小于0.05为有统计学意义。结果:颌下腺涎石的CT平均值与预刺激比下的最大suv有显著相关(r = 0.558, p<0.05)。刺激前后的最大suv分别为1.5±1.1和2.1±0.7 (p = 0.026)。结论:涎腺SPECT/CT越野车对颌下腺结石患者腮腺和颌下腺的定量管理具有临床应用价值。

Submandibular sialolithiasis with CT and SPECT/CT: CT values, standardized uptake values, and salivary gland excretion in the parotid and submandibular glands.

Objectives: Recently, SPECT/CT has been widely accepted as a valuable diagnostic tool in dentistry. The aim of this study was to investigate submandibular sialolithiasis with CT and SPECT/CT, especially CT values, standardized uptake values (SUVs), and salivary gland excretion in the parotid and submandibular glands.

Methods: A prospective study was performed in 13 patients with submandibular sialolithiasis who underwent CT and salivary gland SPECT/CT. The CT values and the SUVs of parotid and submandibular glands were obtained using a workstation and software. The salivary gland excretion in the parotid and submandibular glands was defined as ratio of pre- to post-stimulation on SUVs. A P-value lower than .05 was considered as statistically significant.

Results: In the submandibular glands with sialoliths, the average CT values were significantly correlated with the maximum SUVs at ratio of pre-stimulation (r = 0.558, P<.05). The maximum SUVs at ratio of pre- to post-stimulation in the submandibular glands with and without sialoliths were 1.5 ± 1.1 and 2.1 ± 0.7, respectively (P = .026).

Conclusion: The salivary gland SPECT/CT SUVs can be useful in clinical practice for the quantitative management of parotid and submandibular glands in patients with submandibular sialolithiasis.

期刊介绍: Dentomaxillofacial Radiology (DMFR) is the journal of the International Association of Dentomaxillofacial Radiology (IADMFR) and covers the closely related fields of oral radiology and head and neck imaging. Established in 1972, DMFR is a key resource keeping dentists, radiologists and clinicians and scientists with an interest in Head and Neck imaging abreast of important research and developments in oral and maxillofacial radiology. The DMFR editorial board features a panel of international experts including Editor-in-Chief Professor Ralf Schulze. Our editorial board provide their expertise and guidance in shaping the content and direction of the journal.
