Outcomes and Complications of Image-Guided Percutaneous Tumour Ablation for Hepatocellular Carcinoma at the Irish National Liver Transplant Centre.

Image-guided tumour ablation is a minimally invasive treatment for early stage hepatocellular carcinoma (HCC). Our study reviews the complications and long term outcomes in patients treated at a tertiary referral centre. Retrospective study.

Pre-operative radiomics model for prognostication in resectable pancreatic adenocarcinoma with external validation.

Objectives: In resectable pancreatic ductal adenocarcinoma (PDAC), few pre-operative prognostic biomarkers are available. Radiomics has demonstrated potential but lacks external validation. We aimed to develop and externally validate a pre-operative clinical-radiomic prognostic model.

C-arm cone-beam CT parenchymal blood volume imaging for transarterial chemoembolization of hepatocellular carcinoma: implications for treatment planning and response.

We report on the feasibility of C-arm cone-beam computed tomography (CBCT) parenchymal blood volume imaging (PBVI) performed immediately following transarterial chemoembolization (TACE) of hepatocellular carcinoma (HCC) to assess the need for repeat treatment. Eighteen TACE procedures were included. A retrospective assessment was made for the presence or absence of residual disease requiring treatment on immediate post-TACE PBVI and on interval follow-up multidetector computed tomography (MDCT) or magnetic resonance imaging (MRI).

Practical tips and tricks for assessing prosthetic valves and detecting paravalvular regurgitation using cardiac CT.

Paravalvular leaks are an uncommon but serious complication of prosthetic valves. Transthoracic echocardiography is used in the assessment of prosthetic valves but can be limited by acoustic shadowing from the prosthesis and poor acoustic windowing. Small case series have previously shown cardiac CT to have promising results in detecting paravalvular leaks.
