CT or MRI With Anesthesia: An Oncology Preparation Planner
Who this guide is for
Caregivers preparing a dog for CT or MRI used to map a tumor, guide biopsy, stage disease, or plan surgery or radiation.
Guide summary
Clarify the imaging question, contrast and anesthesia plan, required records, order of imaging and biopsy, recovery expectations, and who will interpret the study.
Before you start
Follow only the imaging center’s current food, water, and medication instructions. Report heart, airway, kidney, liver, seizure, bleeding, and prior anesthesia concerns. Transfer original DICOM studies when possible rather than screenshots or photographed films. If instructions conflict, pause and ask the treating clinic to reconcile them; do not choose the instruction that seems easiest.
Step-by-step guidance
- Ask the clinician to state the one or two questions the scan must answer.
- Confirm which body region and whether contrast, multiple phases, or more than one area is planned.
- Ask whether imaging must precede biopsy, surgery, or medication that could alter findings.
- Review preanesthetic examination and testing, airway needs, positioning, warming, and recovery monitoring.
- Confirm a board-certified radiologist or appropriate specialist will interpret the complete study.
- Leave with image-transfer access, report timing, recovery instructions, and escalation thresholds.
What to monitor
After discharge, observe alertness, breathing, balance, vomiting, appetite, urination, the catheter site, and return to normal behavior. Continue monitoring the tumor-specific problem the scan was intended to evaluate. Write observations in neutral terms with date and time. A home log supports clinical decisions but does not authorize a medication change or replace examination, laboratory testing, imaging, or emergency triage.
When to call a veterinarian
Call for repeated vomiting, increasing sedation, catheter-site swelling, or inability to take prescribed medicine. Emergency care is appropriate for breathing difficulty, collapse, seizures, inability to stand, blue or very pale gums, or rapid deterioration. When urgent transport is advised, bring the current medication list and call ahead if that does not delay departure.
