The purpose of this study was to assess the attenuation characteristics of the Alloderm Biologic Mesh Spacer (ABMS) in the abdomen and pelvis. Of nine patients with ABMS, five underwent multidetector computed tomographic scans at 1, 4, and 7 months postsurgery. Two patients underwent positron emission tomography-computed tomography (PET-CT). The pre- and postcontrast images were evaluated for attenuation characteristics of ABMS. The PET-CT scans were reviewed for [18F]-fluorodeoxyglucose (FDG) uptake. We observed increase in the attenuation characteristics of the spacers on follow-up imaging (P<.05). No FDG uptake was noted on PET-CT. To conclude, ABMS demonstrates soft tissue attenuation on noncontrast CT and shows increase attenuation on serial CT scans.
本研究的目的是评估同种异体真皮生物网片间隔物（ABMS）在腹部和骨盆的衰减特性。9例使用ABMS的患者中，5例在术后1、4和7个月接受了多排螺旋计算机断层扫描。2例患者接受了正电子发射断层扫描-计算机断层扫描（PET-CT）。对增强前后的图像进行评估，以了解ABMS的衰减特性。对PET-CT扫描结果进行[18F]-氟脱氧葡萄糖（FDG）摄取情况的复查。我们观察到在随访成像中间隔物的衰减特性增加（P<0.05）。PET-CT上未发现FDG摄取。总之，ABMS在非增强CT上表现为软组织衰减，在系列CT扫描中显示衰减增加。
