Abstract

A 22 gauge "skinny core" (Madayag) biopsy needle, an 18 gauge Menghini needle, and a 14 gauge Tru-cut needle were compared in 51 patients. The Madayag needle was found to have a high recovery rate and provided adequate histological information in a large percentage of cases. However, the larger needles more consistently demonstrated a higher recovery rate and diagnostic specimen than the Madayag needle. The authors recommend that the radiologist become familiar with all three types of needles to facilitate selection of the proper instrument in each case.

摘要

在51例患者中对22号“细芯”（马达亚格）活检针、18号门希尼针和14号粗切割针进行了比较。发现马达亚格针回收率高，在很大比例的病例中能提供足够的组织学信息。然而，较大的针比较马达亚格针更一致地显示出更高的回收率和诊断标本。作者建议放射科医生熟悉所有三种类型的针，以便在每种情况下便于选择合适的器械。
