Comparison of MRI and Molecular Breast Imaging in Breast Diagnostic Evaluation

2014-08-27 03:33:49 | BioPortfolio


The purpose of this study is to determine the sensitivity of Molecular Breast Imaging (MBI) relative to MRI of the breast in patients undergoing MRI for a clinical concern, or abnormal diagnostic mammogram and/or ultrasound study.


Background: Breast MRI has excellent sensitivity, but is very expensive and suffers from low specificity. Additional benign biopsies are prompted by MRI in 24-40% of patients. Molecular Breast Imaging (MBI) is a new nuclear medicine technique developed at Mayo. Preliminary MBI results indicate a sensitivity of ~88% for the detection of tumors < 10 mm. The cost of an MBI procedure is expected to be a factor of 5 less than an MRI examination.

Hypothesis: MBI has a comparable sensitivity to MRI at a significantly lower cost.

Study Design: A total of 120 patients will be studied. All patients will have been scheduled for bilateral breast MRI for a clinical concern, problem solving, or abnormal mammogram and/or ultrasound study. All patients will undergo MBI within 3 weeks of the MRI examination.

Potential Outcomes: This study will provide valuable information on the sensitivity of MBI relative to MRI, and to determine if this new technique can be eventually developed as an alternative to MRI for problem solving.

Medical and Biotech [MESH] Definitions

Abnormal accumulation of lymph in the arm, shoulder and breast area associated with surgical or radiation breast cancer treatments (e.g., MASTECTOMY).

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.

Use of ultrasound for imaging the breast. The most frequent application is the diagnosis of neoplasms of the female breast.

Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.

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.
