Abstract
ObjectiveTo compare the image features of magnetic resonance imaging(MRI) and ultrasound(US) for papillary thyroid carcinoma(PTC).
MethodsFrom January 2015 to April 2016, 86 consecutive patients underwent surgery and pathologically confirmed PTCs in the People's Hospital Affiliated to Jiangsu University were selected.All patients received neck US and MRI examination before thyroid surgery.For each case, the US and MRI features emphasized included the echogenic/signal, margin, shape, anteroposterior to transverse diameter ratio(A/T), microcalcifications and lymph node metastasis.Statistical analysis was performed using the χ2 test.
ResultsIn the comparison of US and MRI features, A/T≥1(41.9% in US and 62.8% in MRI) and lymph node metastasis(88.0% in MRI; 56.0% in US) demonstrated statistically significant differences (χ2=7.551, P=0.009; χ2=6.349, P=0.025), and no significant differences were observed in the margin, shape(P=0.724, P=0.316).
ConclusionThe MRI features of PTCs included A/T and lymph node metastasis was superior to US.
