“…DECT with iodine mapping has also uncovered findings not discovered by other imaging techniques in the realm of psoriatic arthritis. In a case of PsA associated with nail psoriasis, DECT with iodine mapping was able to detect active enthesitis in the nail root where X-ray and dermatoscopy of the hyponychium could not [35]. In another study by Umezawa et al, the use of iodine mapping with DECT uncovered a case of psoriatic arthritis in the knee by detecting active enthesitis not evident on prior conventional CT and X-ray images [36].…”

Spectral CT represents a novel imaging approach that can noninvasively visualize, quantify, and characterize many musculoskeletal pathologies. This modality has revolutionized the field of radiology by capturing CT attenuation data across multiple energy levels and offering superior tissue characterization while potentially minimizing radiation exposure compared to traditional enhanced CT scans. Despite MRI being the preferred imaging method for many musculoskeletal conditions, it is not viable for some patients. Moreover, this technique is time-consuming, costly, and has limited availability in many healthcare settings. Thus, spectral CT has a considerable role in improving the diagnosis, characterization, and treatment of gout, inflammatory arthropathies, degenerative disc disease, osteoporosis, occult fractures, malignancies, ligamentous injuries, and other bone-marrow pathologies. This comprehensive review will delve into the diverse capabilities of dual-energy CT, a subset of spectral CT, in addressing these musculoskeletal conditions and explore potential future avenues for its integration into clinical practice.
