Description
Liang and colleagues tested dual-energy CT scans in 2026 as a way to judge thyroid cancer stage, spread to neck lymph nodes, and likely outcome. Dual-energy scanning uses two X-ray energy levels, letting doctors measure iodine uptake and other tissue traits as numbers. The study covered 80 patients, 40 with stage III disease and 40 with stage IV disease, whose scans the team compared against pathology and follow-up.
Stage IV tumors showed clearly higher scan enhancement, averaging 185.4 units against 155.7 units for stage III tumors in the comparison. Iodine load also ran higher in stage IV cancer, at 6.8 milligrams per cubic centimeter against 3.2 for the earlier stage group. Patients above a 145-unit enhancement threshold lived longer without disease returning, and two doctors reading the scans agreed almost perfectly, with a consistency score of 0.963 on the study scale.
