T. Sugahara et al., CT ANGIOGRAPHY IN VASCULAR INTERVENTION FOR STENO-OCCLUSIVE DISEASES - ROLE OF MULTIPLANAR RECONSTRUCTION AND SOURCE IMAGES, British journal of radiology, 71(846), 1998, pp. 601-611
The aim of this study was to assess the efficacy of CT angiography for
steno-occlusive diseases before and after interventional procedures,
focusing on the role of multiplanar reconstruction (MPR) and source im
ages. 17 patients with 20 steno-occlusive lesions underwent CT angiogr
aphy before and after interventional procedures. For each lesion, the
percentage stenosis obtained on CT angiography was compared with that
on conventional angiography. In addition, MPR and source images were e
valuated for the presence of wall thickening and calcification before
interventional procedures, and the presence of dissection and luminal
shape after interventional procedures. These findings were compared wi
th those of conventional angiography. Although the percentage stenosis
depicted on CT angiography correlated well with that on conventional
angiography, MPR and source images clearly demonstrated the effect of
intervention and the residual stenosis. MPR and source images clearly
depicted wall thickening, wall calcification, the presence of dissecti
on and the luminal shape. CT angiography provides useful information b
efore intervention, while MPR and source images are of value in evalua
ting arterial wall abnormalities and morphological changes associated
with interventional procedures.
