Value of computed tomography-based lipiodol retention pattern in the assessment of hepatocellular carcinoma complete response following conventional transarterial chemoembolization

Egyptian Journal of Radiology and Nuclear Medicine

Table 4 The relation of 1st follow-up CT lipiodol retention patterns with final progression statuses and time from cTACE to recurrence in months

		Complete lipiodol retention (N = 21)	Incomplete lipiodol retention (N = 9)	P value
Final progression status	No recurrence	16 (76.2%)	1 (11.1%)	0.001
Final progression status	Recurrence	5 (23.8%)	8 (88.9%)	0.001
Time from cTACE to recurrence (months)	Mean ± SD	5.57 ± 2.69	6.0 ± 2.27	0.743
Time from cTACE to recurrence (months)	Range	3–9	3–9	0.743

The statistical methods of Chi-square test and independent t-test were employed to analyze discrete and continuous variables, respectively
C-Lip complete lipiodol retention, cTACE conventional transarterial chemoembolization, DCE-MRI dynamic contrast-enhanced magnetic resonance imaging, I-Lip incomplete lipiodol retention, SD standard deviation
