Radiofrequency ablation in breast tissue: experimental study for evaluation of radiofrequency effects in the bovine udder and review of the literature.

Purpose: To investigate the radiofrequency (RF) effects on the nonlactating and lactating ex vivo bovine udder as a model for normal breast tissue.

Materials And Methods: RF ablation in three lactating and three nonlactating ex vivo bovine udders (ie, six udders) was performed. The opening of the electrodes was 3 cm.

Bone mineral density, bone turnover, and osteoprotegerin in depressed women with and without borderline personality disorder.

Objective: Low bone mineral density has repeatedly been reported in patients with major depressive disorder (MDD), and MDD has been discussed as a risk factor for the development of osteoporosis. MDD in young adults often occurs in the context of borderline personality disorder (BPD), and both MDD and BPD have been associated with a dysregulation of the hypothalamic-pituitary-adrenal system and subsequent hypercortisolemia. To date, it is unclear whether comorbid BPD in depressed patients modulates the extent of bone mass reduction.

Epidermal cyst of the breast mimicking malignancy: clinical, radiological, and histological correlation.

Background: Epidermal cyst of the breast is a rare benign intramammary lesion; however, a common finding in other parts of the body and most often located in the scalp, back, and neck. Only a few cases of epidermal cysts of the breast have been reported in literature.

Case Report: The patient presented with a small movable left breast lump.

Radiation dose to the radiologist's hand during continuous CT fluoroscopy-guided interventions.

Computed tomography fluoroscopy (CT fluoroscopy) enables real-time image control over the entire body with high geometric accuracy and, for the most part, without significant interfering artifacts, resulting in increased target accuracy, reduced intervention times, and improved biopsy specimens [1--4]. Depending on the procedure being used, higher radiation doses than in conventional CT-supported interventions might occur. Because the radiologist is present in the CT room during the intervention, he is exposed to additional radiation, which is an important aspect.

[Perfusion imaging of the kidney using contrast-enhanced phase-inversion ultrasound].

Purpose: We evaluated different techniques of contrast-enhanced phase-inversion ultrasound to visualize renal perfusion.

Materials And Methods: Levovist contrast-enhanced phase-inversion ultrasound with different levels of mechanical index and frame rate was performed in 20 kidneys. Analysis using a software algorithm for time-resolved perfusion imaging was compared to single-image analysis performed by three independent radiologists.
