Uptake of Gadoxetic Acid as a New Prognostic Factor for Local Recurrence after Chemoembolization of Hepatocellular Carcinoma
Hideki Ishimaru MD et al
DATE: Sunday, November 25 2012
TIME: 02:20-02:30 PM
LOCATION: S405AB
●PURPOSE
Organic anion transporter 8 (OATP8) responsible for hepatocellular uptake of drugs is down-regulated in usual hepatocellular carcinomas (HCCs), which causes low enhancement in gadoxetic acid-enhanced MR imaging. The down-regulation of OATP8 is also supposed to affect uptake of anticancer drugs, causing chemoresistance of HCCs. Some HCCs overexpress OATP8 and show high uptake of gadoxetic acid; the overexpression might influence chemotherapeutic effect.We aimed to investigate whether HCCs showing high uptake of gadoxetic acid are more susceptible to transarterial chemoembolization (TACE).

Preoperative Staging of Non-Small Cell Lung Cancer with Coregistered Whole Body MRI-PET: A Prospective Randomized Controlled Trial
Chin A Yi MD, PhD et al
DATE: Monday, November 26 2012
TIME: 10:30-10:40 AM
LOCATION: S404CD
●PURPOSE
Currently PET-CT plus brain MRI is considered the general method of lung cancer staging. However, upcoming simultaneously acquired whole body MRI-PET is expected to be the future way of accurate staging in patients with non-small cell lung cancer (NSCLC). The purpose of this randomized controlled study was to assess whether coregistered whole body MRI-PET correctly helps upstage lung cancer status in more patients with NSCLC than dose PET-CT plus brain MRI.

Contrast-enhanced PET/CT vs Non-Contrast Enhanced PET/MRI in Abdominal Oncological Lesions Osteopathy-Initial Results
Yasser Assiri MD et al
DATE: Monday, November 26 2012
TIME: 11:00-11:10 AM
LOCATION: S505AB
●PURPOSE
PET/MRI has to measure up to PET/CT and should ideally show diagnostic advantages over PET/CT before introduction into clinical routine. The purpose was to compare contrast-enhanced PET/CT (cePET/CT) and non contrast-enhanced PET/MRI (PET/MRI) concerning diagnostic accuracy in evaluation of abdominal lesions.

DATE: Monday, November 26 2012
TIME: 10:40-10:50 AM
LOCATION: S505AB
●PURPOSE
To evaluate the clinical utility of simultaneous acquisition of PET and MR imaging in patients with gynecologic malignancies and to compare PET/MR images with those obtained with PET/CT.

Usefulness of Half-Fourier Acquisition Single-Shot Turbo Spin-Echo (HASTE) in Evaluation of Local Invasion of Lung Cancer
Suyon Chang MD et al
DATE: Monday, November 26 2012
TIME: 12:15-12:45 PM
LOCATION: Lakeside Learning Center
●PURPOSE
Recently, Half Fourier Single Shot Turbo Spin-Echo (HASTE) imaging with short TE and short inter-echo spacing, has found increased use in lung imaging. The features of HASTE include fast imaging, little motion artifacts, high signal intensity of the fat, and by using parallel imaging, margin blurring can be reduced. Therefore in this study, we evaluated the usefulness of HASTE alone for the evaluation of local tumor invasion of lung cancer.

LOCATION: N230
●PURPOSE
Positron emission tomography (PET) with 18F-fluorodeoxyglucose (FDG), mostly performed in combination with computed tomography (CT) as PET/CT, plays a fundamental role in the staging of non-small lung cancer (NSCLC). The aim of this pilot study was to evaluate the feasibility of PET combined with magnetic resonance imaging (PET/MR) for initial staging of NSCLC.

Epidermal Growth Factor Receptor (EGFR) Mutation in Lung Adenocarcinoma: Its Relation with CT, PET/CT and Diffusion-weighted MRI Findings
Miyeon Yie et al
DATE: Tuesday, November 27 2012
TIME: 09:30-09:40 AM
LOCATION: N230
●PURPOSE
Several studies showed that EGFR mutations are related with adenocarcinoma in situ (AIS, for bronchioloalveolarcarcinoma [BAC]) component on histopathology and the proportion of ground-glass opacity (GGO) within whole tumor at CT as well. Moreover, it has been known that apparent diffusion coefficient (ADC) value at MR imaging in lung adenocarcinomas with high proportion of AIS component is higher than adenocarcinoma without AIS component. The purpose of this study was to evaluate interrelationship between the presence of EGFR mutation in lung adenocarcinomas and ADC value at MR imaging, maximal SUV (standardized uptake values, SUVmax) at PET/CT, or GGO extent within the tumor at CT.
