Detection of Ablation Boundaries Using Different MR Sequences in a Swine Liver Model.

Purpose: To determine the magnetic resonance (MR) sequences best suited for the assessment of ablation zones after radiofrequency ablation (RFA).

Methods: Three percutaneous MR-guided RFA of the liver were performed on three swine. Four pre-contrast and two hepatobiliary post-contrast sequences were obtained after ablation.

Two case reports: Breast schwannoma and a rare case of an axillary schwannoma imitating an axillary lymph node metastasis.

A 79-year-old woman with a newly detected oval circumscribed lump in subcutaneous location on mammography and ultrasound turned out to be a Schwannoma after ultrasound-guided core needle biopsy. A 72-year-old woman with breast cancer in medical history demonstrated a new axillary mass in follow up, initially regarded as a lymph node metastasis. Core needle biopsy did not lead to a sufficient diagnosis.

Periportal fields cause stronger cooling effects than veins in hepatic microwave ablation: an in vivo porcine study.

Background: Vascular cooling effects are a well-known source for tumor recurrence in thermal in situ ablation techniques for hepatic malignancies. Microwave ablation (MWA) is an ablation technique to be considered in the treatment of malignant liver tumors. The impact of vascular cooling in MWA is still controversial.

Abuse as a Cause of Childhood Fractures.

Background: It is well known that physical abuse of children all too often escapes detection. Fractures are among the potential consequences of physical abuse but are also com- mon in childhood because of accidents. A question frequently addressed to the Medical Child Protection Hotline (Medizini- sche Kinderschutzhotline) is how fractures due to abuse can be distinguished from accidental fractures.
