AMERICAN JOURNAL OF ROENTGENOLOGY. An International Multicenter Comparison of Time-SLIP Unenhanced MR Angiography and Contrast-Enhanced CT Angiography for Assessing Renal Artery Stenosis: The Renal Artery Contrast-Free Trial

Timothy S. E. Albert1, Masaaki Akahane, Isabelle Parienty, Nancy Yellin, Violeta Catalá4, Xavier Alomar, Antoine Prot, Nobuo Tomizawa, Huadan Xue, Venkata S. Katabathina, Jorge E. Lopera and Zhengyu Jin

OBJECTIVE. The unenhanced MR angiography (MRA) technique time-spatial labeling inversion pulse (time-SLIP) may provide a safe alternative for evaluating the renal arteries for stenosis. This international multicenter trial tested the hypothesis that time-SLIP unenhanced MRA is accurate and robust for assessing the renal arteries for stenosis in comparison with contrast-enhanced CT angiography (CTA).

GASTROENTEROLOGY AND HEPATOLOGY. High local recurrence of early-stage hepatocellular carcinoma after percutaneous thermal ablation in routine clinical practice

Chinnaratha, Mohamed A.; Sathananthan, Dharshan; Pateria, Puraskar; T, Edmund; MacQuillan, Gerry; Mosel, Leig; Pathi, Ramon; Madigan, Dand; Wigg, Alan J.

Background and aim: The risk of local tumour progression (LTP) and factors predicting LTP following percutaneous thermal ablation (PTA) of early-stage hepatocellular carcinoma (HCC) have not been well studied in non-trial settings and may be underestimated. We aimed to assess these outcomes in a multicentre study.

RADIOLOGY. Perfusion CT for Selecting Patients with Acute Ischemic Stroke for Intravenous Thrombolytic Therapy

Kirsteen R. Burton, MBA, MSc, MD, Deljit Dhanoa, MD, Richard I. Aviv, MBChB, Alan R. Moody, MBBS, Moira K. Kapral, MD, MSc, Andreas Laupacis, MD, MSc

Stroke is a common disease that produces substantial long-term health and economic burdens (1–3). In Canada, the annual cost of care within the 1st 6 months of stroke is estimated at $2.5 billion Canadian (4). Acute ischemic stroke (AIS) constitutes approximately 85% of all strokes, with optimal management requiring timely access to neuroimaging (computed tomography [CT] or magnetic resonance [MR] imaging) and thrombolytic therapy (5,6). The introduction of thrombolytic therapy for patients with AIS has increased the importance of the use of diagnostic imaging technologies to guide the selection of patients most likely to benefit from thrombolytic medications.

JOURNAL OF VASCULAR AND INTERVENTIONAL RADIOLOGY. Radioembolization in Patients with Progressive Gastrointestinal Stromal Tumor Liver Metastases Undergoing Treatment with Tyrosine Kinase Inhibitors

Nils Rathmann, MD, Steffen J. Diehl, MD , Dietmar Dinter, MD , Jochen Schütte, MD , Daniel Pink, MD , Stefan O. Schoenberg, MD , Peter Hohenberger, MD

Purpose: Gastrointestinal stromal tumors (GISTs) spread frequently to the peritoneum and the liver. If metastasectomy or tyrosine kinase inhibitors (TKIs) fail, interventional ablation techniques are considered. The purpose of this study is to assess the progression-free interval (PFI) of GIST liver metastases after radioembolization (RE).
