4D CT扫描用于肿瘤(如肺癌)的诊断和治疗(更清晰地观察动态结构)

 新的仪器、新的诊断、新的希望--- 四维计算机断层扫描（4D CT）代表着下一步的影像成像:

图1 是上面文章里的肺部4D CT 扫描图.外行人看热闹,不知radiologist和肿瘤医生有何高见?

图3: 在心脏方面---常规的LVG和4D-CT-VG的比较图

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.

广域4D CT扫描给"无法手术"的肺癌病例带来希望:
