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).

Boeck sarcoidosis of the breast: mammographic, ultrasound, and MR findings.

The rare case of sarcoidosis of the breast is presented. The mammographic, ultrasound, and MR appearances are described.

Is there a correlation in breast carcinomas between tumor size and number of tumor vessels detected by gadolinium-enhanced magnetic resonance mammography?

Tumor vessels are known as a sign of malignancy in breast tumors. Is there a correlation between tumor size and the number of vessels in cases of breast tumor examined by dynamic gadolinium (Gd)-enhanced MR imaging? Eighteen patients (mean age, 46 +/- 7 years) underwent dynamic Gd-enhanced MR imaging of the breast by three-dimensional gradient echo sequence using thin-layer technique (2.5 mm) at 1.

[Can the high-resolution 13-MHz ultrasonography facilitate the preoperative localization and marking of microcalcification clusters?].

Purpose: The value of 13 MHz ultrasound regarding the preoperative localisation in combination with mammography were investigated into.

Material And Method: Out of 112 mammaographically detected calcifications, 30 (30 patients) were clusters of microcalcifications. Out of these, 23 were classified as suspicious of malignancy and were preoperatively localised with a 7.

[Ultrasound examination of the female breast: comparison of 7.5 and 13 MHz].

Purpose: We investigated whether the high resolution ultrasound (13 MHz-scanner) shows smaller lesions and better differentiation than the 7.5 MHz-scanner.

Method: Prospectively, sonography was performed on forty-seven patients with a 7.

[Ultrasound detection of breast cancer with normal mammogram].

In eleven patients with breast cancer the diagnosis was made by using ultrasound as the only method. In none of the patients could mammography show the malignoma. Although six of the patients underwent additional tube X-ray investigation, no radiological criteria of malignancy were found on the mammograms.

[Surgical technique of subcutaneous/skin preserving tumor-adapted mastectomy].

Subcutaneous mastectomy as a procedure to prevent breast cancer has been abandoned because of the insufficient resection of breast tissue and the high rate of complications. Including the recent experiences in reconstructive breast surgery the subcutaneous mastectomy allows a degree of tissue resection comparable to total mastectomy with a lower rate of complications. Surgical technique, our own results and new indications for subcutaneous mastectomy are presented.

[Fibromatosis of the breast].

Fibromatosis of the breast is a rare benign mesenchymal transformation of the connective tissue, the origin of which is probably situated in the fascia of the pectoral muscle and the Cooper's ligaments. In the clinical and radiological examination, it is difficult to differentiate between a mammary carcinoma or other malignant tumours of the breast. Only histological examination can lead to the final diagnosis.

[Disseminated lymphangioleiomyomatosis].

Clinical and histological findings of generalised lymphangioleiomyomatosis are demonstrated. A 40-year old woman died within a few weeks because of massive pulmonary involvement. Tumour mass in the area of the left ovary together with enlarged lymph nodes suggested a metastasising ovarian cancer.
