Abstract |
基礎検討では, 4次元CTで計測した流速は超音波の流速値と比例関係にあり, CTで流速計測が可能になることを示した。次に臨床応用を4つの領域で検討した。鼻咽頭機能評価では, 閉鎖不全腔を定量評価できることから重症度判定が正確で, 従来のX線検査及び侵襲のある喉頭鏡を置換できる可能性があることを示せた。ステントグラフト後のendoleak評価では, 従来のCTと比べ4次元CTは診断能が向上し, 多くの症例で血管造影を置換できることを示せた。更に, 排尿中に4次元CTを撮影すると排尿機能を評価でき, 排尿障害患者の様々な尿路閉塞の原因を特定できることを示した。整形領域では, 関節運動の定量評価ができることを示した。
For fundamental analysis, we took 4D-CT to measure the flow velocity of vascular phantom. The measurements had a linear correlation to those taken by Doppler US, which helped to indicate potential use of 4D-CT in measuring flow velocity. In regards to clinical application, we evaluated the usefulness of 4D-CT in four clinical fields. In otolaryngology, 4D-CT provided quantitative data of the regurgitated area, which will enable the replacement of conventional X-ray and invasive laryngoscopy. In cardiology, 4D-CT data showed higher diagnostic accuracy compared to conventional CT for the evaluation of endoleak after vascular stentgraft, which will help to decrease the use of invasive angiography. In urology, 4D-CT scans taken during the bladder voiding process allows visualization and clarification of the cause of obstruction in patients with dysuria. In orthopedics, with 4D-CT we could achieve quantitative analysis of joint movement, which has been difficult using X-ray.
