●ABSTRACT
Purpose:To introduce the technical aspect of cryotherapy and how the physics of cryotherapy applies to the treatment of lung cancer.Methods: Review the current data available on cryotherapy and the use of this technique in the treatment of cancers in general. Introduce the specific technical issues that are raised with applying this technique to the lung.Results: Discuss the currently available clinical data for the treatment of thoracic malignancies in the chest with cryotherapy.Discussion: Allow the learner to apply some of the information attained in this session by showing ablative cases.

Detection of Hepatocellular Carcinomas: Angiographic CT (CTAP/CTHA) vs Gadoxetate Disodium-enhanced MRI
Satoshi Goshima et al

DATE: Monday, November 26 2012
TIME: 10:50-11:00 AM
LOCATION: E451A
●PURPOSE
First, to compare the performance of angiographic CT (CT during arterial portography [CTAP] and CT hepatic arteriography [CTHA]) versus gadoxetate disodium-enhanced MRI for detection of hepatocellular carcinomas (HCCs). Secondly, to determine if HCC lesions read as “false-negative” by gadoxetate disodium-enhanced MRI are detected by angiographic CT.

Recommended Iodine Dose for Hepatic Arterial-dominant Phase CT Images of the Liver for Visualizing Hypervascular Hepatocellular Carcinoma (HCC): Multicenter Prospective Study in 91 Community Ho
spitals in Japan
Utaroh Motosugi et al

DATE: Monday, November 26 2012
TIME: 11:10-11:20 AM
LOCATION: E451A
●PURPOSE
We conducted a study in 91 institutions as a postmarketing surveillance to investigate the effects of various contrast material (CM) injection protocols of multiphasic contrast-enhanced CT of the liver, which has been reported in ECR2012. Here, we attempted to determine the recommended iodine dose of CM for hepatic arterial-dominant phase (HAP) images of the liver from the study data.

Hot Topic Session: Pediatric Radiology in the Future
Vicente Gilsanz MD et al

DATE: Tuesday, November 27 2012
TIME: 07:15 – 08:15 AM
LOCATION: E350
●Abstract
Common adult diseases, such as cardiovascular disease, diabetes, stroke and osteoporosis, are difficult to treat and costly, accounting for the greatest proportion of current public healthcare expenditures. To overcome current treatment limitations and effectively reduce the costs associated with these common diseases, research should be geared towards the identification of useful biomarkers for their early detection, leading to the development of appropriate preventive strategies.

Transcatheter Therapies for Liver Cancer—What’s Best and When
Michael Soulen MD

DATE: Wednesday, November 28 2012
TIME: 02:20-02:40 PM
LOCATION: S405AB
●ABSTRACT
Chemoembolization is the standard of care for unresectable/unablatable HCC in patients with preserved liver function, based on two randomized trials demonstrating improved survival compared to best supportive care. Conventionally, chemoembolization has been performed using a drug emulsion with Lipiodol, ever since observations in the 1980’s and 1990’s that Lipiodol is selectively taken up and retained in liver tumors, that it serves as a drug carrier for local tumor-specific delivery, and that Lipiodol retention is an imaging biomarker for both pathologic response and for survival.Bland embolization with microparticles alone, which has been done since the 1960’s for hepatic tumors, was largely supplanted by chemoembolization. The randomized trial by Llovet which established the survival benefit from chemoembolization also had a bland embolization arm with nearly identical results, falling just shy of statistical significance when the trial was closed. Survival data for HCC patients in the United States treated with bland embolization is indistinguishable from that reported for chemoembolization in a similar US population.Drug-eluting embolic beads are a new platform for intra-hepatic drug delivery with better local drug retention and decreased systemic toxicities compared to Lipiodol chemoembolization. Improvement in cancer outcomes for HCC have yet to be demonstrated. Beads canbe loaded with irinitecan to treat metaststic colon cancer, with encouraging ongoing trials suggesting additive benefit over systemic chemotherapy alone.Radioembolization with yttrium-90 microspheres is a less toxic therapy than chemoembolization with similar oncologic outcomes in HCC and metastatic disease. There are no comaprative trials of radioembolization andchemoembolization. Studies of combinations of radioembolization with systemic chemotherapy for metastatic disease are underway.
