PURPOSE:
To investigate the feasibility of magnetic resonance lymphangiography (MRL) protocol using a gadolinium (Gd)-based contrast agent (Gd-MRL) for breast patients in a typical clinical setting, and to establish a Gd-MRL protocol and identify potential MRL biomarkers for differentiating metastatic from non-metastatic lymph nodes.

Prepectoral Edema as a Morphological Sign in MR-mammography
Clemens G Kaiser, et al.

DATE:Monday, December 2nd 2013
TIME:03:50 PM – 04:00 PM
LOCATION:Arie Crown Theater
PURPOSE:
Morphological and kinetic signs of breast lesions contribute to diagnosis and differential diagnosis in MR-Mammography. Prepectoral edema in patients without any history of previous biopsy, operation, radiation or chemotherapy has been detected as a new diagnostic Sign during clinical routine. The purpose of this study was to evaluate the role of this morphological sign in the differential diagnosis of breast lesions.

CODE:LL-BRS-TU1B
Scientific informal presentations
MR Imaging of Breast before and after Neoadjuvant Chemotherapy: Does Breast Parenchymal Enhancement in the Contralateral Normal Breast Change after Chemotherapy?

TIME:12:45 PM – 01:15 PM
LOCATION:Lakeside Learning Center
PURPOSE:
To investigate the change of breast parenchymal enhancement (BPE) on MRI, in the contralateral normal breast of patients who received neoadjuvant chemotherapy (NAC) for breast cancer.
【コメント】
乳癌の化学療法前後での背景乳腺の濃染の程度を評価した報告。化学療法後では前にくらべ濃染の程度が低下すると結論しています。
 
 

CODE:LL-BRS-TU7B
Scientific informal presentations
Breast Cancer Staging: Comparison of Whole-body Hybrid MR/PET and PET/CT Imaging: Initial Experience

DATE:Tuesday, December 3rd 2013
TIME:12:45 PM – 01:15 PM
LOCATION:Lakeside Learning Center
PURPOSE:
To compare the diagnostic staging performance and SUV measurement accuracy of whole-body hybrid MR/ PET with PET/CT in patients with breast cancer.
【コメント】
乳癌のstagingとPETでのSUVに関して全身PET-MRIとPET-CTを比較した報告。
 
 

CODE:SSJ01-02
Scientific formal presentations
The Relationship of Breast Density in Mammography and Magnetic Resonance (MR) Imaging in Women at High Risk for
Developing Breast Cancer and Women with Breast Cancer
Freya Schnabel, et al.

DATE:Tuesday, December 3rd 2013
TIME:03:10 PM – 03:20 PM
LOCATION:Arie Crown Theater
PURPOSE:
Mammographic breast density (BD) is associated with a 4 to 6-fold increased risk for developing breast cancer. Background parenchymal enhancement (BPE) in MRI has also been correlated with breast cancer risk. The purpose of our study was to evaluate the relationship between BD, BPE, and FGT (assessment of fibroglandular tissue with contiguous MR images) in women with breast cancer (BC) and at high risk (HR) for developing breast cancer.
【コメント】
マンモグラフィーでの乳腺濃度やMRIでの背景乳腺の濃染、線維腺組織の程度と乳癌との関連を検討した報告。これらの因子は乳癌家族歴や遺伝子異常などをもった乳癌ハイリスクグループに比べて乳癌の発症率が高く乳癌のリスクファクターであると結論しています。

PURPOSE:
To determine the cancer detection rate on short-term and long-term follow-up MRI after a benign concordant MRI-guided breast biopsy.
【コメント】
MRガイド下生検で良性と診断された症例に対するMRIを用いた短期及び長期経過観察の結果の検討。生検後のMRIによる経過観察で新たに指摘された乳癌はわずかに0.6%で、良性と診断された症例に対するMRIによる経過観察の有用性は低いと結論しています。

DATE:Wednesday, December 4th 2013
TIME:03:40 PM – 03:50 PM
LOCATION:Arie Crown Theater
