中文摘要 | 總計100頭患卵巢囊腫之德國黃斑乳牛,先以直腸檢查診斷後,再用 B-mode超音 波配備 5-MHz 之探頭,經由直腸掃瞄其囊腫直徑及囊壁厚度作區別診斷。 於超音波掃瞄下 診斷標準為: 囊腫至少大於 20mm 以上, 其囊腫壁小於 3mm 者為濾泡囊腫, 而大於等於 3mm 者則判定為黃體囊腫。同時採集牛乳,以商品化 on-farm test 半定量測試其黃體助孕 素濃度來判定超音波診斷的正確性。根據商品化 on-farm test 之判定標準: 牛乳黃體助孕 素濃度若低於 1ng/ml 者,則判定為濾泡囊腫 (79 頭 ), 而大於等於 1ng/mI 者,則視為 黃體囊腫 (21 頭 )。 以牛乳黃體助孕素濃度來判定 B-mode 超音波區別兩種囊腫形態之正 確診斷率,其結果分別為: 濾泡囊腫為 90 . 4%,而黃體囊腫則為 76.5%。 本試驗顯示出 ,以 B-mode 超音波對牛隻濾泡囊腫及黃體囊腫的診斷和傳統的直腸檢查比較下,確實可提 高其區別診斷率。 |
英文摘要 | In ovarian cysts of 100 cows as determined by rectal palpation, the diameter and the wall thickness were assessed sonographically per rectum with a 5-MHz probe. Structures larger than 20 mm in diameter with a wall thickness < 3 mm were classified as follicular cysts, while those larger than 20 mm in diameter with a wall thickness ≧ 3 mm were determined as luteal cysts. A correct ultrasonographic diagnosis was based on the on-farm test for progesterone concentrations of simultaneously collected milk samples, according to the definition of the commercial progesterone test, < 1 ng/ml for follicular cysts (79 cows) and ≧ 1ng/ml for luteal cysts (21 cows). The ultrasonographic classification of cyst type was consistent with the milk progesterone concentration in 90.4% of follicular cysts and 76.5% of luteal cysts. The results show that follicular and luteal ovarian cysts can be better distinguished with B-mode ultrasonography than with conventional rectal examination. |
