DOI: 10.1007/s11748-018-0898-x

Abstract: A 64-year-old woman, with a history of hepatocellular carcinoma, developed recurrent metastatic lung nodules after lung metastasectomy 10 years ago. Computed tomography (CT) revealed tumors in the right middle, and left lower lobes. We planned a… read more here.

DOI: 10.1016/j.ejrad.2019.108756

Abstract: PURPOSE Intravenous contrast administration is crucial in many CT examinations but also poses a potential risk to the patient. Monoenergetic images (MonoE) of dual-energy CT systems can virtually increase iodine attenuation and might improve image… read more here.
