甲狀腺核醫掃描使用放射性碘或鎝同位素評估甲狀腺功能及定位異常組織。為貓甲狀腺機能亢進診斷及碘131治療前評估的重要工具,可區分單側或雙側病變、異位組織。
貓甲狀腺機能亢進診斷及碘131治療前必要檢查
Hypothyroidism is the most common endocrinopathy in dogs, typically from lymphocytic thyroiditis or idiopathic atrophy. Diagnosis requires total T4, free T4, and TSH. Hyperadrenocorticism (Cushing's disease) is common in middle-aged to older small breed dogs, with pituitary-dependent form accounting for 80-85% of cases.
建議：0.9% NaCl（DKA）或含 Dextrose 晶體液（低血糖），依病因調整
類型：0.9% NaCl
監測頻率：回診時 + 居家監控

建議數日內就診評估，非立即危及生命但不宜拖延 (evaluation within days recommended, not immediately life-threatening)
