Dr. Martinez will be responsible for all aspects of the canine imaging study at the performance site as described in the attached NC State IACUC Protocol #20-133, approved 16-Mar -2020 Specifically, Dr. Martinez will be in charge of: - Identifying and enrolling 25 patient animals (dogs) to participate - Injecting the contrast and performing the imaging per the protocol referenced above. o Approximately 10 animals to be imaged post-injection using a varying time between injection and scan using the 20s imaging technique on VetCAT. o Approximately 15 animals to be imaged concurrent with injection while varying scan times and injection times. - Evaluation of images of the enhanced vessels and tissues, tumor visibility (if applicable), vessel continuity, degree of enhancement, distinction between arterial and venous anatomy, presence or absence of artifact, and clinical utility. Comparison to conventionally acquired CT images if available. - Prepare a brief summary report of relevant observations - Ultimately responsible for all patient care for all enrolled subjects. The purpose of this project is to establish cranial contrast CT imaging protocols in an animal (canine) organism providing a level of realism beyond what is achievable in a laboratory phantom model.
