In vivo trans-rectal ultrasound–coupled optical tomography of a transmissible venereal tumor model in the canine pelvic canal

Abstract: In vivo trans-rectal near-infrared (NIR) optical tomography was performed concurrently with, albeit reconstructed without spatial a prior of, trans-rectal ultrasound (US) on transmissible venereal tumor (TVT) developed as a model in the canine pelvic canal. Studies were taken longitudinally at prior to, 14 days after, and 35 days after the TVT injection. As the tumor grew, the nodules became increasingly hyperabsorptive and moderately hyperscattering on NIR. The regions of strong NIR contrast, especially on ab… Show more

“…Red discharges can also be produced in AWAN, ALI, MUSHTAQ IJAZ, CHAUDHRY, AWAN The same no of cases were mentioned as in Table 2 different pathological conditions therefore should be confirmed [19] . This study implicates that owners considering red vulvar discharge as sole breeding indicator were posing their dogs to contract and spread this disease to other dogs (OR=1.96).…”

“…To discriminate between cancerous and healthy tissues, some authors used the fact that tumors are more vascularized than the surrounding tissues to measure attenuation by Near Infrared Spectroscopy Techniques [3]. Optical characteristics (absorption and diffusion) of healthy and cancerous prostates were clinically measured [4].…”
