Imaging of the Canine Heart Using Non ECG-Gated and ECG-Gated 64 Multidetector Computed Tomography
ECG-gated multidetector computed tomography (MDCT) is an imaging modality widely utilized for the evaluation of cardiac pathology by physicians. However, there has been little research of cardiac MDCT imaging in veterinary patients. Presently, ECG-gating is an upgrade for MDCT, which few veterinary …

Effectiveness of 64-Slice Multi-Detector Row Computed Tomography for Diagnosing Acute Pyelonephritis in Children
… 적용되지 않았다. 그러나 최근 다중탐지 CT (multi-detector row CT, MDCT) 개발로 촬영시간이 단축되면서 소아에서도 신 병변을 평가하는데 CT를 적용할 수 있게 되었다. 이에 본 연구에서는 급성 신우신염으로 아주대병원에 입원하였던 환아 중 MDCT와 DMSA 검사를 모두 받았던 경우를 대상으로 두 검사의 결과를 비교분석함으로써, 기존에 신우신염 진단에 가장 민감한 검사법으로 알려져 있는 DMSA 스캔에 비하여 MDCT의 진단적 효용성을 비교하고자 하였다. 대상 및 방법: 발열성 요로감염으로 입원하였던 환아 …
