The use of Dual Energy CT in acute hand pathology in the Emergery Department. How to use the DE bone marrow oedema, tendon and gout application to problem solve. Limitations of Dual Energy CT and reduction of application artefacts.

Hand pathology counts for 10% of hospital Emergency Department (ED) visits. There are new and exciting Dual Energy CT (DECT) applications which can be utilised at initial presentation. DECT scan with DE bone marrow application, which has an estimated dose <0.05 mSv, can make a less convincing fracture easier to identify. Tendon injuries can also be interrogated, the tendon application allows them to be traced along their course through the hand. Diagnostic dilemma of acute joint pathology, infection or crystalline arthropathy can be addressed with the gout application identifying urate within a joint, reducing the need for an invasive procedure. The principles of Dual Energy CT. Dose of Dual Energy CT in the hand and estimated fatality risk of solid cancer. Exciting new DE bone marrow oedema with colour overlay maps and comparison with virtual non calcium subtraction technique. How the collagen application can be utilised to identify tendon injuries. Managing the diagnostic dilemma of acute joint pathology. Limitations of Dual Energy CT and reducing DECT application artefacts.
