OBJECTIVE We describe a novel and efficient CT biopsy technique that we have termed 'skin adhesive and hand-aided biopsy technique', shortened to the acronym SAHNA. This technique is ideal for biopsying surface osseous lesions where there is a lack of subcutaneous fat. This avoids the need for the radiologist's hand to be in close proximity to the CT scanner beam at the time of intervention. METHODS The SAHNA technique uses a plastic surgical forceps towel clamp to stabilise the biopsy needle just proximal to the lesion after piercing through the skin. The clamp itself is stabilised via a self-adhesive dressing which is stuck down to the skin at its shank. RESULTS In our institution, we have already used the SAHNA technique successfully in over 5 cases. CONCLUSION The SAHNA technique is a widely accessible and effective way of stabilising the CT biopsy needle in technically challenging superficial bony lesions.

表面胶粘剂和手工辅助针刺活检技术（SAHNA）。

目的我们描述了一种新颖而有效的CT活检技术，我们将其称为“皮肤黏附和手工活检技术”，简称为SAHNA。该技术是活检缺乏皮下脂肪的表面骨病变的理想选择。这避免了在介入时放射线医生的手必须紧靠CT扫描仪光束。方法SAHNA技术使用塑料外科手术钳毛巾夹在穿刺皮肤后将病变部位附近的活检针稳定。夹具本身通过一种自粘敷料来稳定，该敷料在其柄部处粘在皮肤上。结果在我们的机构中​​，我们已经成功使用了5例以上的SAHNA技术。
