Performance of Spectral CT-scan in Patients With Metastatic Colorectal Cancer: a Prospective Multicentre Study

Spectral CT is a rapidly expanding imaging modality that allows a reduction in iodine dose and irradiation compared to conventional scanning. It uses the difference in attenuation of the material according to the two different energy levels of the incident x-ray beams. The dual-energy scanner has a wide range of clinical applications, particularly in abdominal imaging.
