- Abstract
Computed tomographic (CT) features of lymph nodes are used for diagnosis, staging, and response evaluation in veterinary patients. The objectives of this study were to describe maximum short- and long-axis transverse diameters (SATD and LATD, respectively), volume, and attenuation of presumed normal canine mandibular lymph nodes (MLNs) and medial retropharyngeal lymph nodes (MRLNs), to investigate the effect of variables on these features, and to describe inter-observer reliability of transverse diameter and attenuation measurement. Computed tomography studies of 161 dogs were retrospectively reviewed. Median values for SATD were 5.2 and 5.4 mm, median values for volume were 0.26 and 0.54 cm³, and median values for attenuation were 32.3 and 31.8 Hounsfield units (HU) for MLN and MRLN, respectively. Median LATD was 11 mm for MLNs. Height of the first cervical vertebra (HCV1) and weight were positively associated with transverse diameters of both MLNs and MRLNs (P < 0.001). Grade of dental disease was negatively associated with transverse diameters of both MLNs (P = 0.001) and MRLNs (P < 0.03). The intraclass correlation coefficient (ICC) was 0.94 [95% confidence interval (CI): 0.94 to 0.95] for transverse diameter measurement. This study provides descriptive data on the CT characteristics of presumed normal MLNs and MRLNs in dogs and describes a highly reliable method of measuring transverse diameter.
