Dedicated breast CT: geometric design considerations to maximize posterior breast coverage.

An Institutional Review Board-approved protocol was used to quantify breast tissue inclusion in 52 women, under conditions simulating both craniocaudal (CC) and mediolateral oblique (MLO) views in mammography, dedicated breast CT in the upright subject position, and dedicated breast CT in the prone subject position. Using skin as a surrogate for the underlying breast tissue, the posterior aspect of the breast that is aligned with the chest-wall edge of the breast support in a screen-film mammography system was marked with the study participants positioned for CC and MLO views. The union of skin marks with the study participants positioned for CC and MLO views was considered to represent chest-wall tissue available for imaging with mammography and served as the reference standard.

Diagnostic performance of a dedicated 1.5-T breast MR imaging system.

Purpose: To assess diagnostic performance of dedicated breast magnetic resonance (MR) imaging at breast imaging centers by using a dedicated 1.5-T breast MR system that used high-spatial-resolution, high-contrast-resolution spiral trajectory acquisitions.

Materials And Methods: The study was institutional review board approved and HIPAA compliant, with waiver of informed consent.

Effectiveness of whole brain radiotherapy in the treatment of brain metastases: a systematic review.

Background: Brain metastases are the most common intracranial tumour in adults, estimated to occur in up to 40% of patients with cancer. Despite being used in clinical practice for 50 years, the effectiveness of whole brain radiotherapy for the treatment of brain metastases remains uncertain.

Objectives: To assess the effectiveness of whole brain radiotherapy (WBRT) on survival and quality of life.

Clinical comparison of full-field digital mammography and screen-film mammography for detection of breast cancer.

Objective: The purpose of this work is to compare full-field digital mammography and screen-film mammography for the detection of breast cancer in a screening population.

Subjects And Methods: Full-field digital mammography was performed in addition to screen-film mammography in 6736 examinations of women 40 years old and older presenting for screening mammography at either of two institutions. Two views of each breast were acquired with each technique.

Comparison of full-field digital mammography with screen-film mammography for cancer detection: results of 4,945 paired examinations.

Purpose: To prospectively compare full-field digital mammography (FFDM) with screen-film mammography (SFM) for cancer detection in a screening population.

Materials And Methods: At two institutions, 4,945 FFDM examinations were performed in women aged 40 years and older presenting for SFM. Two views of each breast were acquired with each modality.

A complication involving a braided hook-wire localization device.

At the authors' institution, needle localization of breast lesions with a braided hook wire involves the wire being cut 1-2 cm from the point of entry before dissection, to avoid contamination of the sterile field with the nonsterile portion of wire. During dissection, the wire is brought through the skin into the area of dissection. In one patient, fragments of wire filaments were left within the breast.

CT sialography: utilising acinar filling.

The technique of computed tomographic sialography (CTS) has been demonstrated to be valuable in the diagnosis of masses of the major salivary glands. Forty-one CT sialograms were performed in 35 patients using acinar glandular filling with oily contrast material. Twenty-two mass lesions and seven cases of inflammatory disease were identified.
