Gallbladder (GB) perforation is a potentially fatal cause of acute abdomen. Higher morbidity and mortality are associated with this entity due to delayed diagnosis and treatment. Ultrasound with color/power Doppler and contrast sonography can detect wall discontinuity; however, sometimes it can be subtle or unavailable. Small vessel slow flow "perfusion" imaging allows improved microvascular perfusion detection using different filters, which result in increased spatial resolution and vessel visualization. Noncontrast perfusion imaging was of immense clinical value in the diagnosis of GB perforation in the six cases presented here. To the best of our knowledge, this is the first case report describing efficacy of noncontrast "perfusion" imaging in detection of GB perforation.
胆囊穿孔是急性腹痛的一个潜在致命原因。由于诊断和治疗延迟，该病症具有较高的发病率和死亡率。彩色/能量多普勒超声及超声造影可检测胆囊壁连续性中断；然而，有时这种中断可能不明显或无法检测到。小血管慢血流“灌注”成像使用不同滤波器可改善微血管灌注检测，从而提高空间分辨率并使血管可视化。非增强灌注成像在此处报告的6例胆囊穿孔诊断中具有巨大临床价值。据我们所知，这是首例描述非增强“灌注”成像在检测胆囊穿孔中有效性的病例报告。
