Measuring thyroid density by energy spectrum CT / 医疗卫生装备

ABSTRACT

Objective To investigate the relationship between the single energy CT value and the tissue density and further evaluate the mass of thyroid.Methods Different substances respectively composed of liquid and solid,liquid and liquid,thyroid gland were selected,and the relationship was investigated between the single energy CT value and the tissue density.Results The CT value was closely related to the content of high atomic number substance.The CT value of thyroid was closely related to the content of iodine.Conclusion It is feasible to measure the thyroid density by the energy spectrum CT.
