Aquilion Prime, radiation dose

Carotid exams using Toshiba’s Aquilion Prime minimize patient radiation dose (non-contrast 0.26 mSv, post-contrast 0.57 mSv). Sub-milliSievert scans could be the norm in the near future thanks to a Medicare ruling, slated to take effect next year. Image courtesy Toshiba America Medical Systems

The heady days of computed tomography (CT) — when 64-slice scanners drove sales to an all-time high — seems like ancient history. Hard to believe it...
CT, Greg Freiherr

A low-dose standard for CT, set to take effect next year, is pushing many providers to upgrade or replace aging equipment. The scan underlying this image exposed the patient to 1.9 mSv. (Image courtesy of Siemens Healthcare)

More than one in three computed tomography (CT) sites surveyed by The Association for Medical Imaging Management (AHRA) could be subject to a 5...
Dual-energy scanning

Dual-energy scanning, achieved on Siemens’ Definition Edge, reduces severe artifacts caused by an implanted pump (left), clearly visualizing surrounding anatomical structures (right). The twin-beam, single-source Edge is one of several platforms that can characterize tissues and structures according to the atomic numbers of their elements. (Image courtesy of Siemens Healthcare)

They were once the kings of computed tomography (CT) — 16-slice scanners that hinted at coronary CT angiography; 64 slicers that delivered it. Today...
breast density, computed tomography

Providers under pressure to deliver low-dose, routine computed tomography (CT) can pick from the best deals ever. Want a spectral or dual-energy CT...

Images reconstructed from a scan done with the Koning Breast CT scanner show the heterogeneously dense breast of a 44-year-old woman in high-contrast and high-spatial resolution. The FDA-approved scanner, with its 10-second scan time and lack of breast compression, is being positioned against breast tomosynthesis and potentially breast MRI. (Image courtesy Koning Corp.)

Lying chest down, head turned to the side, breast suspended through a cutout in the table, women can routinely get a mammogram with computed...
