Localisation of focal liver lesions to specific hepatic segments - comparison of multiphase spiral CT and MR imaging
open access
Abstract
The authors studied prospectively 26 focal liver lesions in 26 patients who had undergone spiral CT and MRI before surgery. Multiphase spiral CT included noncontrast scans, hepatic arterial-dominant phase, portal venous - dominant phase and equilibrium phase. MRI was performed in all cases. The following sequences were performed: SE and TSE T1- and T2-weighted images, STIR and dynamic T1-weighted FFE study after i.v. administration of gadolinium (Gd-DTPA).
The CT and MR scans were prospectively and independently reviewed by three radiologists for visualisation of hepatic and portal veins and segmental localisation of hepatic lesions.
The authors used the right and left main portal veins along with transverse fissura, hepatic veins and gallbladder fossa as landmarks for the tumour localisation to specific hepatic segments.
The primary segmental locations of the lesions were correctly determined with CT in 22 of 26 focal liver lesions (85%) and with MR imaging in 24 of 26 lesions (92%). The full extent of lesions was correctly described with sCT in 19 of 26 focal lesions and with MR in 21 of 26 tumours.
MRI and CT were helpful preoperative tools for determining the segmental location of focal liver lesions and for planning the surgical approach.
