Dual energy CT iodine map for delineating inflammation of inflammatory arthritis

Iodine mapping is an image-processing technique used with dual-energy computed tomography (DECT) to improve iodine contrast resolution. CT, because of its high spatial resolution and thin slice reconstruction, is well suited to the evaluation of the peripheral joints. Recent developments in the treatment of inflammatory arthritis that require early diagnosis and precise therapeutic assessment encourage radiological evaluation. To facilitate such assessment, we describe DECT iodine mapping as a novel modality for evaluating rheumatoid arthritis and psoriatic arthritis of the hands and feet. aEuro cent Dual-energy CT iodine mapping can delineate inflammation of peripheral inflammatory arthritis. aEuro cent DECT iodine mapping has high spatial resolution compared with MRI. aEuro cent DECT iodine mapping has a high iodine contrast resolution. aEuro cent DECT iodine mapping may reflect therapeutic effects.
