Rapid MRI of the breast in evaluating lesions discovered on screening.

Background: In Canada, breast MRI has traditionally been reserved for evaluation of disease extent in patients with known breast malignancy. More recently, MRI has been emerging as an instrument for breast screening. However, its utilization is limited by increased relative cost and increased reader time.

Deformable Registration for Longitudinal Breast MRI Screening.

MRI screening of high-risk patients for breast cancer provides very high sensitivity, but with a high recall rate and negative biopsies. Comparing the current exam to prior exams reduces the number of follow-up procedures requested by radiologists. Such comparison, however, can be challenging due to the highly deformable nature of breast tissues.

Outcomes of percutaneous transluminal angioplasty for pediatric renovascular hypertension.

Background: Up to 10% of hypertensive children will have renovascular disease. Where medical therapy fails to control the hypertension, endovascular techniques can improve renal perfusion. The purpose of this study was to assess the efficacy of angioplasty in controlling renovascular hypertension (RVH) in children.

Fine-needle aspiration biopsy of breast adenomyoepithelioma: a potential false positive pitfall and presence of intranuclear cytoplasmic inclusions.

Cytologic diagnosis of adenomyoepithelioma can be very challenging. We report fine needle aspiration cytology (FNAC) findings of a benign adenomyoepithelioma. The cytologic features are characterized by hypercellularity and the presence of numerous atypical dispersed cells with epithelioid morphology and intact cytoplasm.

Skin breakdown over cochlear implants: prevention of a magnet site complication.

Objective: To determine the prevalence of inflammation of the skin around the magnet of cochlear implants.

Method: A postal survey of 232 children implanted at The Hospital for Sick Children, Toronto, detailing the timing and severity of skin inflammation near the magnet.

Results: Sixty-three children (27%) had at least one episode of skin erythema at the magnet site.
