Conspicuity of Screen-Detected Malignancies on Full Field Digital Mammography vs. Synthetic Mammography.

Rationale And Objectives: To evaluate conspicuity of screen-detected cancers on two-dimensional synthetic mammography (SM) reconstructed from digital breast tomosynthesis (DBT) compared to two-dimensional full field digital mammography (FFDM).

Materials And Methods: IRB-approved retrospective review of consecutive screen-detected cancers from October 1, 2015 to June 30, 2017 was performed. All examinations were reviewed by three radiologists in consensus (n = 224); a score of 1-3 was given to each screen-detected cancer on SM vs.

Cystic mediastinal masses and the role of MRI.

While some cystic masses can be definitively diagnosed on CT, others remain indeterminate. Because of its intrinsic superior soft tissue resolution, MR is an important tool in the evaluation of select mediastinal masses that are incompletely characterized on CT. This review describes how non-vascular MR provides greater diagnostic precision in the evaluation of indeterminate cystic mediastinal masses on CT.

Strengths and Weaknesses of Synthetic Mammography in Screening.

Synthetic mammography (SM) consists of two-dimensional images reconstructed from digital breast tomosynthesis (DBT) data. Unlike standard full-field digital mammography (FFDM), SM does not require additional radiation exposure. SM is being introduced in breast imaging centers because early clinical data demonstrate that synthetic images are comparable to FFDM in cancer detection, positive predictive values, and recall rates.

Cancer Yield of Incidental Breast Lesions Detected on Chest Computed Tomography.

Objective: This study aimed to determine the cancer yield for abnormal breast findings initially identified on chest computed tomography (CT).

Materials And Methods: This institutional review board-approved, Health Insurance Portability and Accountability Act-compliant study retrospectively reviewed reports of 41,217 consecutive chest CT examinations done from January 1, 2006, to December 31, 2011, to identify those with breast findings noted in the impression of the report. Examinations done for staging of newly diagnosed breast cancer were excluded.

Programmable shunts and headphones: Are they safe together?

Object: Programmable shunts have a valuable role in the treatment of patients with hydrocephalus, but because a magnet is used to change valve settings, interactions with external magnets may reprogram these shunts. Previous studies have demonstrated the ability of magnetic toys and iPads to erroneously reprogram shunts. Headphones are even more ubiquitous, and they contain an electromagnet for sound projection that sits on the head very close to the shunt valve.

Intra-operative microwave ablation of liver malignancies with tumour permittivity feedback control: a prospective ablate and resect study.

Background: Tumour permittivity feedback control is a novel method for microwave ablation (MWA) that theoretically allows for larger, more predictable ablations. This prospective case series evaluates the feasibility and efficacy of MWA of liver malignancies using a device with tumour permittivity feedback control.

Methods: Ten consecutive patients initially determined to be candidates for surgical resection of a liver malignancy underwent intra-operative MWA with tumour permittivity feedback control followed by a surgical resection.
