●PURPOSE:
To prospectively evaluate the pure molecular-based (D) and perfusion-related (D*, f) diffusion parameters of focal hepatic lesions with intravoxel incoherent motion (IVIM) MR imaging and to determine if these parameters are useful in the characterization.

Can Human Organic Anion Transporting Polypeptide Mediate the Uptake of Gadoxetate Disodium into Hepatocytes?
Hiromitsu Onishi MD et al
DATE: Wednesday, November 30 2011
TIME: 11:00 AM – 11:10 AM
LOCATION: E353B
●PURPOSE:
To investigate whether human organic anion transporting polypeptide 2 (OATP2) can mediate the uptake of gadoxetate disodium (Eovist; Bayer Schering Pharma, Berlin, Germany) using human cRNA-injected Xenopus leavis oocytes.
CODE: MSVG31-11
SESSION: MR Imaging/Gastrointestinal Series: MR Imaging Evaluation of Hepatocellular Carcinoma The Outcome of Hypovascular and Hypointense Nodules on Hepatocyte-phase Gadoxetic Acid-enhanced Magnetic Resonance Imaging: When Does It Become a Conventional HCC? Three-year Follow-up Study
Ali Muhi MBChB et al
DATE: Tuesday, November 29 2011
TIME: 10:50 AM – 11:00 AM
LOCATION: E351
●PURPOSE:
Nodules that appear hypointense on the hepatocyte phase of gadoxetic acid (Gd-EOB-DTPA) -enhanced magnetic resonance (MR) imaging and hypovascular on arterial phase are often encountered in clinical practice. Such nodules cannot be diagnosed using routine imaging criteria. The purpose of this study was to elucidate the natural history of hypovascular nodules that appear hypointense on hepatocyte-phase Gd-EOB-DTPA-enhanced MR images by focusing on hypervascularization.
CODE: SSQ05-02
SESSION: Gastrointestinal (Abdominal CT Dose Reduction)
Effect of Low Radiation Dose on Image Noise and Subjective Image Quality for Analytic vs Iterative Image Reconstruction in Abdominal CT
Dominik Fleischmann MD et al
DATE: Thursday, December 01 2011
TIME: 10:40 AM – 10:50 AM
LOCATION: E353C
●PURPOSE:
To determine and compare the relationship of radiation dose, image noise, and subjective image quality between filtered back projection (FBP), adaptive statistical iterative reconstruction (ASIR) and model based iterative reconstruction (MBIR) in abdominal CT.
CODE: SSA08-07
SESSION: Gastrointestinal (Advanced Abdominal CT Technique: kVp and Iodine)
Low Contrast and Low Radiation Dose Protocol for Hepatic Dynamic CT at 256-Row CT: Usefulness of Low Tube Voltage and iDose Reconstruction Algorithm
Takeshi Nakaura MD et al
DATE: Sunday, November 27 2011
TIME: 11:45 AM – 11:55 AM
LOCATION: E450B
●PURPOSE:
It has been suggested that low tube voltage scanning allows reducing the radiation- and contrast dose, and that the iterative reconstruction algorithm improves image quality at low tube voltage scanning. We evaluated the feasibility of a low contrast-, low radiation dose protocol at abdominal dynamic CT using 80 kVp and “hybrid iterative reconstruction algorithm (iDose)” at 256-row CT.
CODE: LL-GIS-TU1B
SESSION: Gastrointestinal
Low Tube Voltage Technique CT with Iterative Reconstruction Increases Vascular Enhancement and Reduces Both Radiation Dose and the Amount of Iodine Contrast Agent in the Liver Dynamic Study

DATE: Tuesday, November 29 2011
TIME: 12:45 PM – 01:15 PM
LOCATION: Lakeside Learning Center
●PURPOSE:
To evaluate the enhancement of the liver, aorta, portal vein, IVC, image noise and radiation dose using low tube voltage scan condition.
CODE: LL-GIS-TU3A
SESSION: Gastrointestinal
Image Quality and Radiation in CT of the Pancreas: Comparison of 320-MDCT with and without Adaptive Iterative Dose Reduction and 64-MDCT

DATE: Tuesday, November 29 2011
TIME: 12:15 PM – 12:45 PM
LOCATION: Lakeside Learning Center
●PURPOSE:
To evaluate and compare image quality and radiation in CT of the pancreas acquired using 320-MDCT with and without adaptive iterative dose reduction (AIDR) and 64-MDCT.
