“…To obtain a more accurate volume measurement from MRI scans, the crude images were aligned and manually segmented to generate image boundaries (reconstructions). In that regard and according to Limanond et al [22], a T1 hyperintensive signal lesion on the hyperacute image set was considered to be representative of coagulation necrosis, to generate image boundaries and volume measurements. A complex 3D surface rendering then was created using the boundary data generated from a 3D image (Figs.…”

Purpose:To evaluate diffusion alterations after hepatic radiofrequency (RF) ablation using a navigator respiratorytriggered diffusion-weighted imaging (NRT-DWI) sequence with regard to potential diagnostic information for detection of local tumor progression (LTP). Materials and Methods:One hundred forty-eight consecutive follow-up magnetic resonance (MR) examinations of 54 patients after hepatic RF ablation were reviewed. Apparent diffusion coefficient (ADC) values of ablation zones and liver parenchyma were assessed using a single-shot echoplanar imaging sequence with the NRT technique. ADC values of ablation zones and adjacent signal alterations identified in NRT-DWI were analyzed with regard to LTP. Conclusion:NRT-DWI is useful in the follow-up imaging after RF ablation. ADC-based evaluation of signal alterations adjacent to the ablation zone may contribute to the identification of LTP and nontumoral posttreatment tissue changes.

“…Di conseguenza, la precoce individuazione di nuovi noduli di HCC durante il follow-up risulta fondamentale al fine di migliorare la gestione clinica del paziente e, in ultima analisi, la sopravvivenza [7]. A tale scopo, nella pratica clinica, le tecniche di diagnostica per immagini, e tra queste la tomografia computerizzata multidetettore (TCMD), giocano un ruolo chiave [8,9]. Scopo del presente lavoro è stato quello di valutare l'incidenza di nuovi foci di HCC alla TCMD in pazienti sottoposti a trattamento di RFTA di epatocarcinoma.…”

“…As a consequence, early detection of new HCC nodules at follow-up is crucial to improve clinical management and, ultimately, patient survival [7]. For this purpose, diagnostic imaging, and multidetector computed tomography (MDCT) in particular, plays a key role in clinical practice [8,9]. The purpose of this study was to assess the incidence of new HCC foci at MDCT in patients who underwent RFA.…”

Purpose. The authors sought to assess the incidence of new foci of hepatocellular carcinoma (HCC) using multidetector computed tomography (MDCT) in patients treated with radiofrequency ablation (RFA). Materials and methods. Two readers retrospectively reviewed by consensus the follow-up MDCT studies of 125 patients (88 men and 37 women; mean age 68 years) with 141 HCCs (size 1-5.2 cm; mean 2.2 cm) treated with RFA. MDCT follow-up was performed at 1 and 3 months and every 6-12 months thereafter. Reviewers assessed: (1) the presence of new HCC foci in the same liver segment or in a different segment; (2) complete or incomplete tumour ablation; (3)
