RADIOLOGY. Perfusion Reduction at Transcatheter Intraarterial Perfusion MR Imaging: A Promising Intraprocedural Biomarker to Predict Transplant-Free Survival during Chemoembolization of Hepatocellular Carcinoma

Dingxin Wang, PhD1, Ron C. Gaba, MD, Brian Jin, MD, Robert J. Lewandowski, MD, Ahsun Riaz, MD, Khairuddin Memon, MBBS, Robert K. Ryu, MD, Kent T. Sato, MD, Laura M. Kulik, MD, Mary F. Mulcahy, MD, Andrew C. Larson, PhD, Riad Salem, MD, MBA, Reed A. Omary, MD, MS

Purpose: To investigate the predictive value of transcatheter intraarterial perfusion (TRIP) magnetic resonance (MR) imaging–measured tumor perfusion changes during transarterial chemoembolization on transplant-free survival (TFS) in patients with unresectable hepatocellular carcinoma

AMERICAN JOURNAL OF ROENTGENOLOGY. Percutaneous Imaging-Guided Cryoablation of Liver Tumors: Predicting Local Progression on 24-Hour MRI

Paul B. Shyn, Giovanni Mauri, Raquel Oliva Alencar, Servet Tatli, Shaan H. Shah, Paul R. Morrison, Paul J. Catalano and Stuart G. Silverman

OBJECTIVE. The purpose of this study was to determine which MRI features observed 24 hours after technically successful percutaneous cryoablation of liver tumors predict subsequent local tumor progression and to describe the evolution of imaging findings after cryoablation.

AMERICAN JOURNAL OF ROENTGENOLOGY. Current Status of Imaging-Guided Percutaneous Ablation of Breast Cancer

Bruno D. Fornage and Rosa F. Hwang

OBJECTIVE. The purpose of this article is to briefly describe the various techniques used for percutaneous ablation of breast cancer, their preliminary results, and their limitations. The techniques include thermotherapy (radiofrequency ablation, laser irradiation, microwave irradiation, and insonation with high-intensity focused ultrasound waves), cryotherapy, and irreversible electroporation.

AMERICAN JOURNAL OF ROENTGENOLOGY. Accelerated Balloon-Occluded Retrograde Transvenous Obliteration Without Indwelling Balloon Occlusion for Gastric Varices With Small Gastrorenal Shunts Using a Terminal Gelfoam Plug

Wael M. Darwish, Sean Darushnia and Wael E. Saad

OBJECTIVE. We performed balloon-occluded retrograde transvenous obliteration in three consecutive patients with small gastric varices without indwelling balloon catheter occlusion. Foam of 3% sodium tetradecyl sulfate mixed with iodized oil and room air was injected retrograde through the gastrorenal shunt, followed by a thick absorbable gelatin sponge (Gelfoam, Pfizer) plug under only 10-minute balloon occlusion.

AMERICAN JOURNAL OF ROENTGENOLOGY. Reduction in Portal Venous Pressure by Transjugular Intrahepatic Portosystemic Shunt for Treatment of Hemorrhagic Stomal Varices

Amy R. Deipolyi, Sanjeeva P. Kalva, Rahmi Oklu, T. Gregory Walker, Stephan Wicky and Suvranu Ganguli

OBJECTIVE. Stomal varices can cause life-threatening gastrointestinal hemorrhage in patients with portal hypertension. Optimal therapy is not well defined. The purpose of this study was to determine the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) creation for the treatment of hemorrhagic stomal varices.

RADIOLOGY. Repeatability of Diagnostic Features and Scoring Systems for Hepatocellular Carcinoma by Using MR Imaging

Matthew S. Davenport, MD, Shokoufeh Khalatbari, MS, Peter S. C. Liu, MD, Katherine E. Maturen, MD, Ravi K. Kaza, MD, Ashish P. Wasnik, MD, Mahmoud M. Al-Hawary, MD, Daniel I. Glazer, MD, Erica B. Stein, MD, Jeet Patel, MD, Deepak K. Somashekar, MD, Benjamin L. Viglianti, MD, PhD, Hero K. Hussain, MD

Purpose: To determine for expert and novice radiologists repeatability of major diagnostic features and scoring systems (ie, Liver Imaging Reporting and Data System [LI-RADS], Organ Procurement and Transplantation Network [OPTN], and American Association for the Study of Liver Diseases [AASLD]) for hepatocellular carcinoma (HCC) by using magnetic resonance (MR) imaging.

RADIOLOGY. Detection of Broken Sutures and Metal-Ring Fractures in AneuRx Stent-Grafts by Using Three-dimensional CT Angiography after Endovascular Abdominal Aortic Aneurysm Repair: Association with Late Endoleak Development and Device Migration

Takuya Ueda, MD, PhD, Hiroyuki Takaoka, MD, Ivan Petrovitch, MD, Geoffrey D. Rubin, MD

Purpose: To determine the prevalence of demonstrable stent-graft degradation by using three-dimensional computed tomographic (CT) angiography to assess endoleak and stent-graft migration after endovascular aortic aneurysm repair (EVAR).

RADIOLOGY. Hepatocellular Carcinoma with Portal Vein Tumor Thrombus: Treatment with Transarterial Chemoembolization Combined with Sorafenib—A Retrospective Controlled Study

Kangshun Zhu, MD, Junwei Chen, MD, Lisha Lai, MD, Xiaochun Meng, MD, Bin Zhou, MD, Wensou Huang, MD, Mingyue Cai, MD, Hong Shan, MD

Purpose: To determine the safety and efficacy of transarterial chemoembolization (TACE) combined with sorafenib (hereafter, TACE-sorafenib) in patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT).

AMERICAN JOURNAL OF ROENTGENOLOGY. Sonographic Analysis of the Intercostal Spaces for the Application of High-Intensity Focused Ultrasound Therapy to the Liver

Young-Sun Kim, Min Jung Park, Hyunchul Rhim, Min Woo Lee and Hyo Keun Lim

OBJECTIVE. The purposes of this study were to assess the widths of the intercostal spaces of the right inferior human rib cage through which high-intensity focused ultrasound therapy would be applied for treating liver cancer and to elucidate the demographic factors associated with intercostal space width.
