The optimal contrast media policy in CT of the liver. Part I: Technical notes

Abstract: Latest developments of multidetector computed tomography (MDCT), which is today considered a real volumetric technique, have revolutionized abdominal imaging. Technological improvements such as higher spatial resolution, larger volume coverage and higher temporal resolution, have reduced scan times allowing CT studies of the abdomen within a single breath-hold. Furthermore, the increased number of slices, the submillimetric collimation, and the use of multiple dynamic post-contrast phases per single examinatio… Show more

“…In this study, we focused on the arterial phase delay timing, but changes in other technical parameters may lead to further improvements of the liver CT acquisition protocol. The use of a higher contrast agent concentration and injection rate, a patient-tailored scan delay based on a test bolus of contrast agent, and scanning at lower energy levels are among the most promising developments [6, 14, 15]. …”

“…In all groups, contrast material containing 300 mgI per milliliter was intravenously injected over a fixed duration of 30 s [10]. Single portal venous phasic diagnostic CT scanning was performed 70 s after the injection of contrast material for the portal venous phase [11,12] using a dual-energy scanner (Gemstone Spectral Imaging; GE Healthcare) with fast kilovoltage-switching between 80-and 140-kVp on adjacent views during a single rotation.…”

“…The simultaneous occurrence of maximal enhancement of liver parenchyma with minimal enhancement of the underlying hypovascular liver lesions improves detection. However, most recent studies recommend tailoring the amount of CM according to patients' lean body weight (LBW) [59,60]. In particular, Kondo et al [61] recommend injecting 750 mgI per kg of patients' LBW to maximize the lesion detection rate.…”
