Calcifications on CT distinguish malignant thyroid lesions
The presence of calcification on CT scans of thyroid nodules can neither prove nor rule out malignancy -- but calcification patterns may be one useful tool that radiologists can use to assess the likelihood of cancer, say researchers from China.

Whole-body MRI workup finds common breast metastases
Results of a new study indicate that whole-body MRI is an excellent way to work up newly diagnosed breast cancer patients. Researchers from India found that MRI led to a change in treatment in nearly half of patients, and it also found metastases in some patients before symptoms appeared.

Filtering software boosts CT image quality, lowers dose
Adaptive image filtering can improve CT image quality and reduce image noise, enabling radiologists to lower radiation dose, concluded a study presented at this week's American Roentgen Ray Society meeting in San Diego.

5-year C-RADS analysis shows stable VC screening results
SAN DIEGO - In what is likely the largest screening population ever classified by virtual colonoscopy's standardized reporting system, C-RADS, researchers found stable results over five years in the single-center program, along with a large majority of patients who were able to avoid invasive colonoscopy.

VC shows high diagnostic yield after failed colonoscopy
Virtual colonoscopy finds significant pathology in patients referred after failed colonoscopy, according to a study presented at the Digestive Disease Week meeting in New Orleans. The results show the need for a complete colon exam and highlight VC's strengths in detecting extracolonic abnormalities.

GAO numbers overstate growth in medical imaging
SAN DIEGO - Imaging growth in the U.S. hasn't risen nearly as dramatically as the government says it has; in fact, it's been pretty flat, according to researchers who presented a study on the topic on Monday at the American Roentgen Ray Society meeting.

Flexible sigmoidoscopy of dubious value after VC
The yield of additional pathological findings was quite low in a group of symptomatic patients who underwent flexible sigmoidoscopy after virtual colonoscopy screening, according to a poster presentation at this week's Digestive Disease Week meeting in New Orleans.

HDCT with ASIR recon sharpens low-dose abdominal images
High-definition CT (HDCT) combined with adaptive statistical iterative reconstruction (ASIR) is a good way to diagnose abdominal conditions at very low radiation doses, according to researchers from Hong Kong.

Valkyrie software rides to rescue of CT radiation dose dilemma
An automated software algorithm called Valkyrie that extracts radiation dose information from CT exams and tracks it automatically may help imaging sites better follow patient radiation exposure and avoid overdoses, according to a study presented this week at the American Roentgen Ray Society meeting in San Diego.

Examples of quantification of background parenchymal enhancement (BPE) over fibroglandular tissue (FGT) on breast DCE-MRI scans from three patients. Images from left to right are the first postcontrast T1-weighted images, automated segmentation of the right and left breasts (red contours) and semiautomated tumor segmentation (yellow), automated segmentation of FGT (green), and quantification of BPE (purple) over the FGT regions. (A) Images of a 48-year-old woman diagnosed with invasive ductal carcinoma and assigned a low-risk Oncotype DX distant recurrence risk score (score, 13). The BPE measures at 20% cutoff value were ipsilateral absolute BPE within FGT relative to FGT volume (%BPEF/F) of 9.8% and contralateral %BPEF/F of 9.5%. (B) Images of a 60-year-old woman diagnosed with invasive ductal carcinoma and assigned an intermediate-risk Oncotype DX distant recurrence risk score (score, 19). The BPE measures at 20% cutoff value were as follows: ipsilateral %BPEF/F of 13.3% and contralateral %BPEF/F of 14.7%. (C) Images of a 54-year-old woman diagnosed with invasive ductal carcinoma and assigned a high-risk Oncotype DX distant recurrence risk score (score, 30). The BPE measures at 20% cutoff value were as follows: ipsilateral %BPEF/F of 34.1% and contralateral %BPEF/F of 14.5%. Image courtesy of the RSNA.
