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

Clinical applications

The clinical practice, adaptation and techniques of dual-energy CT is 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 ischaemia
urinary system
- characterisation of renal stones ²
- characterisation of renal cysts and masses ^2-⁴
neuroimaging
- differentiation of haemorrhage from iodinated contrast
- quantification of iodine leak in traumatic haemorrhagic contusions
- bone removal
- optimising imaging
female breast
- identification of silicone leaks from breast implants ²
- improved tumour 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
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
