Abstract: Dual energy scan was performed to differentiate any collection associated with calsium. Case report. This 23 year old man showed severe hyperuricemia and mid thoracic pain and MRI showed collection over posterior epidural thecal sac over T3 until T9. Dual energy CT scan was performed to assess uric acid crystal over thoracic region. The CT result was negative. He was treated over intravenous antibiotic and pain medication. His pain improved  progressively and laboratory results  showed towards normal  value and he was discharged on day twelveth. Conclusion. This case report showed the comprehensive diagnostic tool to yield out the aetiology of  thoracal epidural collection, despite negative result. Keywords: Hyperuricemia, abcess, mid thoracic, dual energy, CT scan

AbstractDual-energy CT, the object is scanned at two different energies, makes it possible to identify the characteristics of materials that cannot be evaluated on conventional single-energy CT images. This imaging method can be used to perform material decomposition based on differences in the material-attenuation coefficients at different energies. Dual-energy analyses can be classified as image data-based- and raw data-based analysis. The beam-hardening effect is lower with raw data-based analysis, resulting in more accurate dual-energy analysis. On virtual monochromatic images, the iodine contrast increases as the energy level decreases; this improves visualization of contrast-enhanced lesions. Also, the application of material decomposition, such as iodine- and edema images, increases the detectability of lesions due to diseases encountered in daily clinical practice. In this review, the minimal essentials of dual-energy CT scanning are presented and its usefulness in daily clinical practice is discussed.

A 75-year-old female patient presented with signs and symptoms of a right hemispheric syndrome. A CT scan of the brain with angiogram showed an acute infarct in the right middle cerebral artery (MCA) territory secondary to thromb-occlusion of the M1 segment of the right MCA. A follow-up CT scan 2 weeks later showed a large hyperdense region in the infarcted area. With the aid of a dual-energy CT scan, this was eventually shown to be due to contrast staining from an earlier administration of iodinated contrast on the same day, rather than frank haemorrhagic conversion of the recent right MCA infarct.
