Technique estimates pediatric dose for DR studies
Monday, November 26 | 12:15 p.m.-12:45 p.m. | LL-PDS-MO2A | Lakeside Learning CenterHeightened concern over radiation dose has led to the development of new methods for calculating and reporting dose delivered to patients during imaging exams. Most of the attention has focused on CT -- but what about digital radiography (DR)?

Road to RSNA 2012: Digital X-Ray Preview
This year's presentations on digital x-ray at RSNA 2012 illustrate the rapid advances being made in this modality. Radiography's conversion to digital is making possible the use of advanced image-processing tools once reserved for more advanced modalities, raising the possibility of better patient care at lower radiation doses.

Chest x-ray use remains stable despite growth in advanced imaging
Thursday, November 29 | 12:15 p.m.-12:45 p.m. | LL-HPS-TH2A | Lakeside Learning CenterUse of basic chest radiography has remained relatively unchanged over the past decade, despite wide fluctuations in procedure volume for more advanced imaging modalities such as CT and MRI, according to a group from Thomas Jefferson University.

Ultralow-dose CT matches chest radiography radiation dose
Thursday, November 29 | 11:20 a.m.-11:30 a.m. | SSQ03-06 | Room S405ABRecent advances in iterative reconstruction have put CT radiation doses within range of those found in chest radiography. So is ultralow-dose CT a realistic alternative to x-ray for chest studies? Researchers from Rikshospitalet at the University of Oslo wanted to find out.

The summated digital variance angiography (DVA) image significantly enhances image quality compared to the digital subtraction angiography (DSA) series I–IV (depicting 4 out of 28 (A), 48 (B) and 28 (C) DSA images) of the low dose (LD) acquisitions. Enhancements of iodinated contrast medium (ICM) by DVA depict small vessel structures in detail while the conventional DSA offers a reduced contrast-to-noise ratio (CNR) using LD acquisitions for standalone diagnostic interpretations.
