Natural language processing predicts need for repeat head trauma CT

Monday, December 2 | 10:50 a.m.-11:00 a.m. | SSC12-03 | Room N229When do head trauma patients need repeat CT scans? When the report suggests the condition is worsening. However, a neuroradiologist review is time-consuming, and scans are sometimes repeated unnecessarily. By automating the process, California researchers hoped to improve CT utilization and cut radiation exposures from unneeded scans in this study to be presented on Monday morning.

Absorbed dose varies between single-, dual-source CT colonography

Sunday, December 1 | 12:30-1:00 p.m. | LL-PHE3075-SUA | Lakeside Learning CenterThe dose readout on your scanner doesn't really tell you much, according to a group from Massachusetts General Hospital, who looked into dose differences between different scanners and scan modes for this education exhibit.

Road to RSNA 2013: CT Preview

In a week packed with scientific presentations, exhibitions, special courses, and hot topic sessions, RSNA 2013 attendees will have plenty of opportunities to broaden their knowledge of emerging techniques such as spectral CT, perfusion imaging, iodine mapping, tissue composition analysis, automated tube current selection, flow mapping, iterative reconstruction, and more.

Iterative reconstruction changes plaque characterization

Sunday, December 1 | 11:25 a.m.-11:35 a.m. | SSA02-05 | Room S502ABDoes iterative reconstruction make a difference in coronary plaque characterization? Researchers from Massachusetts General Hospital think it does; they found that even the reconstruction scheme makes a difference.

No harm in cutting CTPA scan length in pregnant women

Sunday, December 1 | 11:05 a.m.-11:15 a.m. | SSA05-03 | Room N228Shorter scan lengths for CT pulmonary angiography (CTPA) do not reduce the accuracy of pulmonary embolism diagnosis, but they do cut radiation dose substantially, according to a research team from Wisconsin.

Automated tube potential selection cuts neck dose

Sunday, December 1 | 10:45 a.m.-10:55 a.m. | SSA16-01 | Room N227Automated tube potential selection can cut CT dose by as much as a third in patients undergoing neck CT, according to researchers from Germany, who will present their results in this RSNA 2013 session.

Iterative recon delivers quality CCTA at well under 1 mSv

Researchers from China and the U.S. have succeeded in producing ultralow-dose coronary CT angiography (CCTA) exams in a wide range of patients using iterative reconstruction. In the process, they've helped redefine low-dose CCTA to mean far less than 1 mSv in all patients, according to study results published in JACC Cardiovascular Imaging.

Early physics training gives radiology residents a leg up

A new program aimed at infusing a dose of imaging physics into the early training of radiology residents has improved their understanding of both medical physics and radiology, according to an article in the Journal of the American College of Radiology.

Radiology still looms large in ECRI's top 10 hazards

Medical radiation no longer tops the top 10 list of technology hazards published each year by the ECRI Institute. That dubious honor, for the second year in a row, goes to those beeping, buzzing, distracting, infuriating, wolf-crying alarms that are becoming ubiquitous throughout healthcare.

ASTRO: Proton therapy shows promise in breast cancer treatment

Proton radiation achieves similar health-related quality of life measures compared to photon radiation in breast cancer patients.

$Representative injuries in patients from the mass casualty incident of October 7, 2023. (A) Axial CT scan at the pelvic level in a 34-year-old male patient shows multiple shrapnel fragments in the pelvis, resulting in fractures of the pelvic bones and lumbar vertebrae (not visible on this image). (B) Coronal reconstruction of a head CT scan in a 20-year-old male patient shows penetrating trauma to the left eyeball with a retained bullet in the orbital cavity. (C) Radiograph of a fetus delivered by emergency cesarean section from a critically injured mother shows a left pneumothorax and catheter in place. (D) Radiograph in a 25-year-old female patient shows a comminuted fracture in the tibial metaphysis with fragment displacement and multiple bony fragments in the surrounding soft tissues.$
