Radionuclide scrotal imaging (RSI) detects varicocele (VC) by demonstrating pooling of tracer on images and reflux of tracer on dynamic images. It is an effective, simple, and noninvasive method for the diagnosis of VC. Here, we presented two cases use RSI to detect VC. A 19-year-old male had left scrotal pain noted for 3-4 days. Blood flow phase images showed increased blood flow along the left spermatic cord vessels to upper aspect of left hemiscrotum. Blood pool phase images and tissue perfusion phase images showed persistent increased blood pooling along the left spermatic cord vessels to upper aspect of left hemiscrotum. Besides, accumulation of focal radioactivity in the upper aspect of right hemiscrotum was also noted. It concluded that compatible with bilateral VCs, severe on the left side. Another 33-year-old male had left inguinal fullness and pain for 2 days. Blood pool phase images and tissue perfusion phase images showed that increased blood pooling in upper aspect of left hemiscrotum and minimally increased on the right side. It concluded that left-side VC considered.

放射性核種陰囊造影檢查藉由觀察放射性示踪劑聚集和回流的動態影像來檢測精索靜脈曲張。放射性核種陰囊造影是有效、簡單、準確且非侵入性的方法。在此，我們提出兩案例使用放射性核種陰囊造影檢查檢測精索靜脈（spermatic vein）曲張。某19歲男性有陰囊悶痛持續3-4天。在血流相（blood flow phase）影像顯示發現左側精索靜脈到左側上半部陰囊有血流量增加；在血池相（blood pool phase）和組織灌注相（tissue perfusion phase）影像顯示沿著左側精索靜脈到左側上半部陰囊有血流量仍持續聚集增加，在右側上半部陰囊也發現有局部放射性示踪劑聚集。左、右兩側都需考慮精索靜脈曲張的狀況，左側精索靜脈曲張的狀況較嚴重。另一名33歲的男性有腹股溝腫脹疼痛且持續2天。在血池相和組織灌注相影像顯示沿著左側精索靜脈到左側上半部陰囊有血流量增加，右側精索靜脈有少許血流量增加。左側需考慮精索靜脈曲張的狀況。
