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 ...

INDICATIONS: 49 year-old patient with shortness of breath. Possible PE. Possible occupational lung disease. PROCEDURE: Consecutive axial slices were obtained without and with intravenous contrast. Bolus thin slices were performed through the pulmonary arteries. The pulmonary trunk shows no evidence for ...

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。这两者在物质密度-碘图上都是可视化的,且都能在VNC图像上被去除;因此,可能很难区分这两者。此外,钡和碘具有相似的衰减曲线,不...
PROCEDURE: Consecutive axial slices were obtained without and with intravenous contrast. Bolus thin slices were performed through the pulmonary arteries. The pulmonary trunk shows no evidence for thrombus or embolus. There is no evidence for a saddle embolus. The right and left main pulmonary arteries...
Computed tomography (CT) is widely used to identify anomalies in brain tissues because their localization is important for diagnosis and therapy planning. Due to the insufficient soft tissue contrast of CT, the division of the brain into anatomical meaningful regions is challenging and is commonly do...
