Dual-energy computed tomography in children: Technique and clinical applications

Figure 6 A 7-month-old female with fever and abnormal body movements, suspected of having either a bleed or meningoencephalitis. A: Axial blended contrast enhanced image showed abnormal leptomeningeal enhancement; B: Image at 70 kV showed marked increased contrast with increased conspicuity of the abnormal enhancement; C: Image at 150 kV showed decreased noise but at the cost of poor contrast; D: Virtual non-contrast image ruled out any abnormal bleed; E: Iodine-specific image showed iodine uptake in the region of hyperdensity, adding to the confidence in the diagnosis of meningitis.
