Plain-English summary
A 10-year-old female dog was diagnosed with a bladder tumor after ultrasound showed a mass. Further imaging with MRI and CT confirmed that the tumor was invasive, affecting the bladder's muscular layer. These advanced imaging techniques helped the veterinarian assess the extent of the cancer, which is important for planning treatment. While the study focused on imaging methods, it highlights the importance of using MRI and CT to get a clearer picture of bladder tumors in dogs.

Abstract
This study described high-field magnetic resonance imaging (MRI) and computed tomography (CT) characteristics of muscle-invasive bladder transitional cell carcinoma (TCC) in two dogs. Ultrasonography revealed a urinary bladder mass with ambiguous result about invasion to the muscular layer. Contrast-enhanced CT showed that the bladder wall in which the mass was attached was more intensely enhanced than the normal bladder walls, supporting invasion to the muscular layer. The mass revealed an intermediate signal intensity with interruption of the hypointense muscular layer on T2-weighted MRI and showed greater enhancement compared with the normal bladder wall on postcontrast T1-weighted images. T2-weighted MRI, postcontrast T1-weighted MRI and contrast-enhanced dual-phasic CT were useful for evaluating muscle-invasive bladder TCC in dogs.
