[Interventional MR-mammography: manipulator-assisted large core biopsy and interstitial laser therapy of tumors of the female breast]].

The present study investigated the clinical application of magnetic resonance (MR)-guided breast interventions, such as manipulator-assisted large core breast biopsy (LCBB) inside a 1.5 T whole-body magnet and MR-guided interstitial laser therapy (ILT). Sixteen patients underwent LCBB and 1 additional patient underwent 4 sessions of ILT of a recurrent undifferentiated lymph node metastasis in the axilla using a Nd-YAG laser (1064 nm).

Normative values of bone parameters of children and adolescents using digital computer-assisted radiogrammetry (DXR).

Purpose: To verify whether estimation of bone mineral density (BMD) using digital X-ray radiogrammetry (DXR) is possible on children and to determine normative values of both such a DXR-BMD estimate and a corresponding metacarpal index (DXR-MCI) on.

Patients And Methods: In retrospect, X-rays were selected of the hands of 200 healthy Caucasian children (120 boys and 80 girls, aged 4-18 yr). The involved children were selected among a larger group of children submitted to the surgical department of our institute for evaluation of a suspected fracture after an occurred trauma.

Animal-based model to investigate the minimum tumor size detectable with an electrical impedance scanning technique.

Rationale And Objectives: The purpose of this study was to determine the minimum tumor size detectable with electrical impedance scanning (EIS) in laboratory animals.

Materials And Methods: VX2 tumor cells (1 mm3) were implanted bilaterally into the upper leg musculature of five white New Zealand rabbits. EIS and ultrasound (US) were performed before, during, and immediately after implantation and on every 2nd day thereafter until tumors could be visualized with both modalities.

Cryotherapy of breast cancer under ultrasound guidance: initial results and limitations.

The aim of this study was to investigate the potential and feasibility of ultrasound-guided cryotherapy in breast cancer. Fifteen female patients with 16 breast cancers (mean tumour diameter 21+/-7.8 mm) were treated.
