Magnetic resonance-guided biopsy of suspicious breast lesions with a handheld vacuum biopsy device.

Purpose: To evaluate a handheld vacuum-assisted device system for magnetic resonance image (MRI)-guided breast lesion biopsy.

Material And Methods: In 32 patients, a total of 42 suspicious breast lesions (mean diameter 7.5 mm for mass lesions, 11.

[Accuracy of routine MRI in lesions of the supraspinatus tendon--comparison with surgical findings].

Purpose: To determine the correlation of the extent of lesions of the supraspinatus tendon in MRI's of the shoulder with surgical or arthroscopic findings using the classification of Snyders and Batemann, respectively.

Materials And Methods: The preoperative MRI's of 80 patients (age: 16 - 76/47.4 +/- 14.

Role of power Doppler techniques and ultrasound contrast enhancement in the differential diagnosis of focal breast lesions.

The purpose of this article is to demonstrate the diagnostic impact of ultrasound in differentiating focal breast lesions with special regard on power Doppler and US contrast agents. The sonographic evaluation of breast lesions has become a standard procedure during the past 15 years. Especially the improvement of B-mode resolution and the use of high-frequency probes increased the diagnostic value of US.

[Analysis of vascularity in breast tumors--comparison of high frequency ultrasound and contrast-enhanced color harmonic imaging].

Purpose: To compare the ability of standard power Doppler and color harmonic imaging for visualising breast tumor vascularity using ultrasound probes of various frequencies, and to evaluate the influence on diagnostic accuracy using ultrasound contrast agent.

Materials And Methods: Twenty patients (x = 43.6 +/- 11.

Cellular distribution and function of soluble guanylyl cyclase in rat kidney and liver.

Soluble guanylyl cyclase (sGC) catalyzes the biosynthesis of cGMP in response to binding of L-arginine-derived nitric oxide (NO). Functionally, the NO-sGC-cGMP signaling pathway in kidney and liver has been associated with regional hemodynamics and the regulation of glomerular parameters. The distribution of the ubiquitous sGC isoform alpha 1 beta 1 sGC was studied with a novel, highly specific antibody against the beta 1 subunit.
