Evaluation of Lossy data compression of chest X-rays: a receiver operating characteristic study.

Rationale And Objectives: To evaluate the quality of chest radiographs after 32:1 compression/decompression with different image compression algorithms.

Methods: Ten digital (Thoravison) radiographs of an anthropomorphic chest phantom with superimposed simulated nodular lesions (NL) and linear reticular lesions (LL) were obtained. Each radiograph was subdivided into 15 fields; they contained the lesions with a probability of 0.

Experience with the Advanced Breast Biopsy Instrumentation (ABBI) system.

Background: The Advanced Breast Biopsy Instrumentation (ABBI) System is designed to excise nonpalpable breast lesions under stereotactic control. We report our experience with special regard to the histological evaluation of margins.

Patients And Methods: Breast biopsies using the ABBI system were performed on 101 patients with microcalcifications.
