The purpose was to compare contrast-enhanced PET/CT (cePET/CT) and non contrast-enhanced PET/MRI (PET/MRI) concerning diagnostic accuracy in evaluation of abdominal lesions. METHOD AND MATERIALS 21 patients (mean age 59.5 years, range 35 to 78 years, 11 female, 10 male) with suspected ...
降低对比剂的碘浓度也有助于提高VNC图像的质量,因为静脉期衍生的VNC图像比动脉期衍生的VNC图像具有更低的残留碘。 DECT的好处之一是能够识别疑似消化道出血患者的对比剂外渗,而无需进行真正的真实平扫(true noncontrast,TNC)采集。肠腔内的碘可能是由于静脉注射的对比剂或残留的口服对比剂的外渗造成的。这两者在物质...
