4D CT掃描用於腫瘤(如肺癌)的診斷和治療(更清晰地觀察動態結構)

 新的儀器、新的診斷、新的希望--- 四維計算機斷層掃描（4D CT）代表著下一步的影像成像:

圖1 是上麵文章裏的肺部4D CT 掃描圖.外行人看熱鬧,不知radiologist和腫瘤醫生有何高見?

圖3: 在心髒方麵---常規的LVG和4D-CT-VG的比較圖

Conventional LVG and the corresponding 4D-CT-VG of 3 patients with acute myocardial infarction (A, broad anteroseptal wall; B, localized inferior wall; and C, inferolateral wall). Wall motion abnormalities (akinesis) in the infarct lesions evaluated by 4D-CT-VG were concordant with those observed by LVG (arrowheads). With 4D-CT-VG, observation of left ventricular wall motion is possible in any direction, interactively (postprocessing interactive manner). ED indicates end diastole; ES, end systole; RAO, right anterior oblique; and LAO, left anterior oblique.

廣域4D CT掃描給"無法手術"的肺癌病例帶來希望:
Wide-area 4D CT gives hope in cases of 'inoperable' lung cancer
