Dual-energy CT or spectral CT is a computed tomography technique becoming increasingly common in clinical practice due to the rapid rise in computer technology and expanding literature exhibiting vast advantages over conventional single-energy CT.

This article is limited to its clinical applications only, the technical part can be found in the main article, see: dual-energy CT

Clinical applications

The clinical practice, adaptation and techniques are broken into individual articles:

virtual non-contrast imaging
vascular
- automated bone removal in CT angiography ²
- decrease metal device artifact ⁷
- detection of endoleaks ⁷
- blood pool imaging ²
  - detection of pulmonary embolism
  - detection of myocardial ischemia
urinary system
- characterization of renal stones ²
- characterization of renal cysts and masses ^2-4
neuroimaging
- differentiation of hemorrhage from iodinated contrast
- quantification of iodine leak in traumatic hemorrhagic contusions
- bone removal
- optimizing imaging
female breast
- identification of silicone leaks from breast implants ²
- improved tumor conspicuity of breast cancers relative to conventional CT, with the potential determination of prognostic biomarkers such as ER and PR status ⁶
musculoskeletal
- detection of bone marrow edema
- detection and quantification of urate crystals in gout
- reduction of metal artifact ⁷
abdominal imaging
- pancreatic diseases ⁵
- detection of acute bowel ischemia ⁹
- determine the composition of gallstones and urinary tract calculi ⁹
- increase the conspicuity of enhancement in inflammatory conditions such as appendicitis ⁹
thoracic imaging
- detection of pulmonary thromboembolism; structural as well as functional information is obtained through iodine maps of pulmonary perfusion ⁷
- assessment of a solitary pulmonary nodule to determine malignancy status ^7,8
