A Pilot Study of Ultrasound-Guided Cryoablation of Invasive Ductal Carcinomas up to 15 mm With MRI Follow-Up and Subsequent Surgical Resection.

Objective: The purpose of this study was to evaluate the effectiveness of ultrasound-guided cryoablation in treating small invasive ductal carcinoma and to assess the role of contrast-enhanced (CE) MRI in determining the outcome of cryoablation.

Subjects And Methods: Twenty consecutive participants with invasive ductal carcinomas up to 15 mm, with limited or no ductal carcinoma in situ (DCIS), underwent ultrasound-guided cryoablation. Preablation mammography, ultrasound, and CE-MRI were performed to assess eligibility.

Compact ultrasound donations to medical facilities in low-resource countries: a survey-based assessment of the current status and trends.

Objectives: Many ultrasound (US) specialists, independently or as part of institutionally directed teams, have donated compact US equipment and training to rural and urban clinics in low-resource regions. The objective of our study was to assess the scope, impact, and characteristics of these donation and training activities.

Methods: We designed a 1-page, 10-question survey soliciting responses on donors, equipment, donation sites, training, and follow-up.
