NCE CT data-set

The second data-set consists of conventional or non-contrast enhanced (NCE) CT images of 56 different cases of patients (31 males and 25 females with age 68 ± 10 years old) diagnosed also with lung cancer. A GE lightSpeed Ultra scanner was used to acquire the NCE CT images, while the acquisition parameters of the NCE images were similar to the CE data-set with the only difference in the resolution and slice thickness, where the NCE CT had an improved resolution of 16 bpp and a thinner slice thickness of 2mm.
