Magnetic Resonance Female Breast Imaging (MRFBI) - Evaluation of the Changes in Signal Intensity over Time Pre- and Post-administration of 0.2 mmol/kg Gd-DTPA.

Purpose: We are looking for a threshold value to discriminate between benign and malign breast lesions in MRI of female breast after administration of 0.2 mmol Gadolinum-DTPA/kg bw.

Materials And Methods: Double coil breast MRI (1.

[Optimal use of MRI mammography from the economic viewpoint].

With the introduction of the contrast agent gadolinum DTPA there were hopes that "MRM" would prove to be the investigatory technique that would largely solve the problems of breast diagnostics. However, after the early years of acceptance, the new method of investigation became a subject of controversy. Nonetheless, MRM today occupies a recognized place in diagnostics for certain indications.

D-galactose-based signal-enhanced color Doppler sonography of breast tumors and tumorlike lesions.

Rationale And Objectives: This study sought to evaluate prospectively the diagnostic potential of unenhanced and enhanced color Doppler and power Doppler for the differentiation of tumors and tumorlike lesions of the breast.

Methods: Ninety-two patients with 110 tumors or tumorlike lesions of the breast were investigated by unenhanced and enhanced color and power Doppler ultrasound. The sonomorphologic aspects of vascularization were analyzed.

[Color-coded signal-enhanced duplex ultrasonography of space-occupying intramammary processes].

Purpose: Prospective comparison of plain and signal-enhanced frequency and amplitude-modulated colour Doppler ultrasound of intramammary tumours to evaluate new criteria for diagnostic analysis.

Methods: Frequency and amplitude-modulated colour Doppler examination with qualitative and quantitative analysis of 80 potentially malignant intramammary lesions were performed before and after application of d-galactose.

Results: Signal-enhanced sonography revealed a typical vessel morphology of primary and recurrent breast cancer facilitating differential diagnosis.

Peripheral washout sign on contrast-enhanced MR images of the breast.

Purpose: To assess the value of the peripheral washout sign on delayed contrast material-enhanced magnetic resonance (MR) images in differentiation of benign from malignant breast masses.

Materials And Methods: In 49 women with 79 breast lesions (55 malignant and 24 benign), dynamic contrast-enhanced MR imaging was performed every 90 seconds during the first 7 minutes and repeated at 10, 20, 30, 40, 50, and 60 minutes after injection of contrast material. Qualitative analysis of the images was performed to evaluate the presence of the peripheral washout sign (a hypointense zone in the periphery of the lesion relative to the center).
