The premier resource for using contrast media in imaging.

TYPE L - ACR/OXY/MED Hard 20 FT Lengths is Cleaned And Capped/Degreased to ensure tube reaches customer in a pure, defect-free state. In addition, our ACR tube is nitrogen charged up to 8-1/8 OD. ACR tube is also suitable for Refrigeration, Natural Gas And Medical gas systems according to ASTM B-280, B-819.

Evidence-based guidelines to assist referring physicians and other providers in making the most appropriate imaging or treatment decision. An interactive way to find AC topics, variants, clinical scenarios and recommendations using keyword filters and search.

ACR Copper Tubing: What It Is, And When, Where, and How It is Used . ACRCT is used in the Air Conditioning and Refrigeration Field Service Industry and is designated by the tube's actual OD. Only hard drawn ACRCT is marked with color; annealed is not.

The ACR BI-RADS atlas divides breast density into 4 categories: almost entirely fatty, scattered fibroglandular elements, heterogeneously dense, and extremely dense based on the proportion of fibroglandular tissue (compared with fat) and its potential for masking of noncalcified lesions [2].

Copper tube for air-conditioning and refrigeration field service (ACR) is designated by actual outside diameter. "Temper" describes the strength and hardness of the tube. In the piping trades, drawn temper tube is often referred to as "hard" tube and annealed as "soft" tube.

ACR category a: The breasts are almost entirely fatty. ACR category b : There are scattered areas of fibroglandular density. ACR category c : The breasts are heterogeneously dense, which may obscure small masses.
