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.

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.

Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles). Present study’s reviewing radiologist deemed AI marking to correspond with site of DCIS.

Axial contrast-enhanced CT scan in a 28-year-old premenopausal woman shows an incidentally detected solid-appearing left ovarian lesion (solid arrow) anterior to the uterus (U), associated with trace ascites in the right adnexa and cul de sac (dashed arrows). At pathologic analysis, this was shown to be ovarian dysgerminoma. Two readers misdiagnosed this lesion, one as a leiomyoma and one as an ovarian fibroma.

ISMRM: AI spots ischemic heart disease on low GBCA dose images

Representative stress perfusion CMR case with 80% contrast dose reduction. Pixel-wise MBF maps and AHA 16-segment bull's eye plots are shown for full-dose and reduced-dose acquisitions. When analyzed using the proposed MST deep learning method, the reduced-dose data closely matches the full-dose data across basal, mid, and apical slices. In contrast, Fermi-deconvolution shows good agreement in apical and mid slices but overestimates MBF in some basal segments, indicating reduced accuracy under low-dose conditions.

Breast texture patterns on mammo may predict cancer risk in dense breasts
By Amerigo Allegretto
Radiomic phenotypes found on mammography may be linked to elevated breast cancer risk in women with dense breasts.
May 13, 2025
Full-field digital mammography (FFDM) images in a 52-year-old woman show a high-risk phenotype (top), and FFDM images in a 58-year-old woman show a low-risk phenotype (bottom). The high-risk phenotype was defined by having high values of the first principal component (PC1) and was assigned to cluster 3 (top row), and the low-risk phenotype was defined by having low values of the PC1 and was assigned to cluster 1 (bottom row). The index images (left side; before any diagnosis of cancer) are provided as well as follow-up images obtained at either the time of cancer diagnosis (for the high-risk phenotype, top right) or at the last follow-up (low-risk phenotype, bottom right). The red circle indicates the location of subsequent breast cancer. Both women had a BI-RADS breast density of C. The woman at high risk for breast cancer was Black and the woman at low risk for breast cancer was white.
