Findings on intraprocedural non-contrast computed tomographic imaging following hepatic artery embolization are associated with development of contrast-induced nephropathy

Table 2 Non-contrast computed tomographic findings and their association with contrast-induced nephropathy development

Association between non-contrast CT findings and CIN (n = 106)
Renal enhancement pattern	Group A (n = 11) (%)	Group B (n = 95) (%)	P value
Early excretory	6 (55%)	2 (2%)	< 0.001
Late excretory	5 (45%)	93 (98%)
Renal artery calcifications	Group A	Group B
Yes	6 (55%)	20 (21%)	0.01
No	5 (45%)	75 (79%)

CT: Computed tomography; CIN: Contrast-induced nephropathy.
