16 MDCT를 이용한 CT Urography의 유용성

The Usefulness of Computed Tomography Urography with 16-Channel Multidetecter Computed Tomography

Purpose To evaluate the usefulness of computed tomography urography with 16-channel multidetecter computed tomography in patients with urinary track disease. Materials and Methods IN 28 patients who underwent CT urography from May 2004 to December 2004. The clinical symptoms of these patients include; renal donors or hematuria, which were clinically suggestive of urinary system disorders. All studies were performed on a siemens sensation 16 scanner with 16mm detectors. CT scans were obtained on a unenhanced, arterial phase, 1,3,5 minites with the following technique : a collimator of 5mm a pitch of 1, and 3d reconstrutions at a thickness of 2mm with intervals of l.5mm. Intravenous administered of the normal saline 50 ml immediately after injecting contrast medium(at a rate of 3 ml/sec). Results Of these 28 patients,(9men and 19 women, age ranged from 20 to 79 years old, mean age 44.8 years)l4 patients(46.7%) were proven to have no 뮤normal disease, 4 patients(13.4%) were with renal stones or hydronephrosis, and there were 10 patients(40.9%) of other urinary system disorders. Conclusion CT urography is a very useful modality to evaluate kidny-transeplatation donors, hematuria and flank pain in the patients with urinary track disease
