Multiple B-value Diffusion-weighted Imaging(DWI) in Evaluation of Breast Lesions

2015-08-20 20:53:24 | BioPortfolio

Summary

Breast cancer is the most commonly diagnosed cancer in women and its definite diagnose is still challenge for radiologist. This study is going to evaluate multi-b value diffusion weighted imaging in discrimination of breast benign and malignant lesions and explore the diagnostic effect of the combination of multi-parameter. At the same time, pathological specimens of patients will be collected. The relationship between magnetic resonance(MR) parameters and pathology biomarkers will be evaluated. Hope multi-b value diffusion weighted imaging can improve diagnosis for breast lesion and provide the basis for clinical treatment. The fundamental of pathology on MR signal change will be further expounded.

Description

Breast cancer is the most commonly diagnosed cancer in women and its definite diagnose is still challenge for radiologist. This study is going to evaluate multi-b values diffusion weighted imaging in discrimination of breast benign and malignant lesions and explore the diagnostic effect of the combination of multi-parameters. At the same time, pathological specimens of patients will be collected. The relationship between MR parameters and pathology biomarkers will be evaluated. By pre-contrast and post-contrast multi-b values diffusion weighted imaging series, patient's Apparent diffusion coefficient(ADC),tissue diffusivity (D), pseudo-diffusion coefficient (D*), perfusion fraction (f), distributed diffusion coefficient(DDC) and alpha will be evaluated. Parameters of benign , malignant breast lesions and ipsilateral or contralateral normal breast parenchyma as a control group will be measured. Receiver operating characteristic (ROC) curve analysis is used to test the ability of different parameters in differentiating malignant from begin lesions. After Surgical operation, specimen of lesion will be collected(Not every patient's specimen will be collected. The investigators should be approved by patient themselves). The biomarkers of specimen will be detected by pathological and molecular-biological methods.Then analyze the relation between parameters of the MR imaging and pathological/molecular-biological biomarkers.

Non-Invasive Magnetic Resonance Imaging (MRI) and Magnetic Resonance Spectroscopy Techniques (MRS) for Assessing Neoadjuvant Chemotherapy in Locally Advanced Breast Cancer

The goal of this clinical research study is to learn if magnetic resonance imaging (MRI) with magnetic resonance spectroscopy (MRS) can show the effects of pre-surgical chemotherapy in bre...

Magnetic Resonance Imaging (MRI) Correlation to Standard of Care Imaging and Pathology Correlation in Breast Carcinoma

Magnetic Resonance Imaging (MRI) is a well known imaging tool for the investigation and diagnosis of breast cancer, used in addition to breast mammograms and ultrasound. Recent publication...

Study First Step to Virtual Breast Cancer Localization

Radioisotopic and wire localizations suffer from several limitations. These techniques add another procedure prior to surgery, can be uncomfortable and entail additional cost. The aim is ...

Combined Breast MRI and Biomarker Strategies in Identifying High-risk Breast Cancer Patients

This clinical trial studies normal breast tissue changes combined with breast magnetic resonance imaging (MRI) that may suggest the beginnings of cancer development. Using breast tissue ma...

Multifunctional Magnetic Resonance Imaging in Predicting Breast Lesions in Women Undergoing Mastectomy for Breast Cancer

Repeatability and Reproducibility of 3D MR Fingerprinting Relaxometry Measurements in Normal Breast Tissue.

The 3D breast magnetic resonance fingerprinting (MRF) technique enables T and T mapping in breast tissues. Combined repeatability and reproducibility studies on breast T and T relaxometry are lacking.

Quantitative in vivo proton MR spectroscopic assessment of lipid metabolism: Value for breast cancer diagnosis and prognosis.

Breast magnetic resonance spectroscopy ( H-MRS) has been largely based on choline metabolites; however, other relevant metabolites can be detected and monitored.

Preliminary results of computer-aided diagnosis for magnetic resonance imaging of solid breast lesions.

The present study aimed to determine suitable optimal classifiers and investigate the general applicability of computer-aided diagnosis (CAD) to compare magnetic resonance (MR)-CAD with MR imaging (MR...

Is it worth to perform preoperative MRI for breast cancer after mammography, tomosynthesis and ultrasound?

The use of preoperative breast MRI remains controversial despite being the most sensitive technique for the detection of breast malignancies.

Breast lesion detection and characterization with contrast-enhanced magnetic resonance imaging: Prospective randomized intraindividual comparison of gadoterate meglumine (0.15 mmol/kg) and gadobenate dimeglumine (0.075 mmol/kg) at 3T.

Contrast-enhanced magnetic resonance imaging (CE-MRI) of the breast is highly sensitive for breast cancer detection. Multichannel coils and 3T scanners can increase signal, spatial, and temporal resol...

Medical and Biotech [MESH] Definitions

Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.

A fluid-filled closed cavity or sac that is lined by an EPITHELIUM and found in the BREAST. It may appear as a single large cyst in one breast, multifocal, or bilateral in FIBROCYSTIC BREAST DISEASE.

Breast neoplasms that do not express ESTROGEN RECEPTORS; PROGESTERONE RECEPTORS; and do not overexpress the NEU RECEPTOR/HER-2 PROTO-ONCOGENE PROTEIN.

Any neoplasms of the male breast. These occur infrequently in males in developed countries, the incidence being about 1% of that in females.

Tumors or cancer of the human BREAST.
