Evaluation of Accuracy of CT Colonography in the Diagnosis of Adenomatous Polyps and Cancers: A Nation-wide Multi-Center Trial in Japan
Hiroyuki Yoshida PhD et al
DATE:Sunday
TIME:11:05-11:15 AM
LOCATION: E450A
●PURPOSE
To evaluate the sensitivity of CT colonography (CTC) in detecting colorectal polyps and cancers >=6 mm in diameter in approximately 1,260 subjects at increased risk of colorectal cancer using optical colonoscopy as the reference standard.
〈コメント〉:日本人を対象とした大腸3次元CTの診断能に関する大規模臨床試験の報告。今後日本でも広く大腸3次元CTが行われる可能性があり、大変に注目される研究だと思います。

Computer-aided Detection for Minimal-Preparation Multi-Energy CT Colonography
Janne Johannes Nappi PhD et al
DATE:Tuesday
TIME:03:50-04:00 PM
LOCATION: E353C
●PURPOSE
To assess the detection accuracy of CAD for colorectal lesions at minimal-preparation multi-energy CT colonography (ME-CTC). ME-CTC can improve detection performance under challenging reading conditions, because it provides more information about the chemical composition of colonic materials than does conventional CT colonography.

CT Colonography (CTC) in a Population-based Screening for Colon-Cancer (CRC): Preliminary Findings
Gabriella Iussich MD et al
DATE:Sunday
TIME:11:25-11:35 AM
LOCATION: E450A
●PURPOSE
To report preliminary findings of a population-based screening CTC trial
〈コメント〉:500名近くを集めておこなわれたイタリアからの報告。住民検診としての大腸3次元CTの可能性を検討しています。

Scientific Informal (Poster) Presentations
A Virtual Pathology Model for Differentiation of Colonic Polyp Types for CT Colonography
Guopeng Zhang MS et al
DATE:Sunday
TIME:01:00-01:30 PM
●PURPOSE
While differentiating polyps from non-polyp candidates has made good progress for CTC, the task for differentiating different polyp types remains a challenge. This study aims to explore a virtual pathology model to differentiate polyp types, such as hyperplastic (H), tubular adenoma (Ta), tubulovillous adenoma (Va), and adenocarcinoma (A).
〈コメント〉:大腸3次元CTで発見される病変の鑑別を、表面の性状でできないかを検討したとする報告。

Gd-EOB-DTPA Enhanced MR Findings of Borderline Lesions of HCC; Relationship between Signal Intensity on Hepatobiliary Phase Images and Prognosis of the Lesions
Satoshi Kobayashi MD et al
DATE:Monday
TIME:12:15-12:45 PM
LOCATION: Lakeside Learning Center
●PURPOSE
To elucidate the signal intensity patterns of borderline lesions of HCC on hepatobiliary phase Gd-EOB-DTPA (EOB) enhanced MRI and clarify the natural histories of these lesions.
〈コメント〉:肝臓の境界病変では、EOB肝細胞相での信号強度の違いによりその後の癌化の頻度が異なると報告しています。
CODE:LL-GIE4047
Education Exhibits
Hepatocellular Carcinoma: Correlation Between Gadoxetic Acid Enhanced MR Imaging and Uptake Transporter OATP8 Expression
Azusa Kitao et al
●PURPOSE/AIM
1. To review the enhancement mechanism of hepatocellular carcinoma (HCC) on the hepatobiliary phase of gadoxetic acid enhanced MR imaging, especially focusing on the expression of uptake transporter organic anion transporting polypeptide 8 (OATP8).
2. To demonstrate the changes in enhancement ratio on gadoxetic acid enhanced MR imaging and OATP8 expression during multistep hepatocarcinogenesis.
3. To show the biological features of an atypical subtype of HCCs showing high enhancement ratio due to increased expression of OATP8.
〈コメント〉:肝細胞癌におけるOATP8の発現と、MRIの信号強度や悪性度について検討した報告。
CODE:LL-GIE4237

●PURPOSE/AIM
The purpose of this exhibit is to present:1. The radiologic findings in patients with enterohemorrhagic Escherichia coli (EHEC) colitis.2. The imaging features of complications caused by this organism such ashemolytic uremic syndrome (HUS) and its related organ failures.
〈コメント〉:昨年、北陸エリアで集団感染した腸管出血性大腸炎の画像所見に関する報告。

Scientific Informal (Poster) Presentations
Early Peritumoral Enhancement of Bile Ductular Carcinoma: Radiologic Pathologic Correlation
Kazuto Kozaka MD et al
DATE:Wednesday
TIME:05:30-06:00 PM
●PURPOSE
To analyze the hemodynamic features of bile ductular carcinoma (BDC; pure type of cholangiolocellular carcinoma without internal hepatocellular and cholangiocellular carcinoma; CCC) with special references to hemodynamics evaluated by angiography-assisted CT with histopathologic correlation.
〈コメント〉:細胆管癌の画像所見に関してまとめられた報告。

Intraarterially Contrast Enhanced Post Mortem CT with Pulmonary Ventilation
Author List: Jonas Apitzsch MD
