Radiologists can misinterpret children's lung nodules at CT
Lung nodule features that are suggestive of malignancy in adults may indicate the opposite in children -- and vice versa -- according to a study in the May issue of Radiology. New methods are needed to separate benign from malignant lung data in children, according to the authors.

New MRI scanners, applications lead to regulatory upgrades
PEBBLE BEACH, CA - As imaging and interventional applications have multiplied and scanners have grown more powerful in recent years, the dangers in the MRI environment have increased as well. To address the safety issues, regulatory bodies are currently updating old MRI safety standards and are developing new ones, according to a presentation at the Society for Medical Innovation and Technology (SMIT) meeting on Friday.

Image guidance evolves into imaging therapy
PEBBLE BEACH, CA - Traditional image-guided therapy is giving way to a brave new world of therapeutic imaging. The difference is more than semantic, say scientists who are developing new technologies to heal patients as well as diagnose them. It amounts to a new emphasis on the cure, and myriad ways to achieve it with the aid of imaging technology.

CAD aids polyp detection in 64-slice study
In one of the first virtual colonoscopy studies to use a 64-slice CT scanner with computer-aided detection (CAD), researchers from Germany found that the software found lesions that radiologists missed, missed lesions that radiologists found, and was helpful overall.

CT, MRI show successful vocal cord restoration
A new vocal cord restoration technique injects the body's own fat into damaged vocal cords to restore damaged voice quality. Imaging with CT and MRI show that vocal function not only improves after the procedure, but endures over follow-up periods of at least four years.

Swedes want to perform VC, but many lack equipment, training
Less than a quarter of Sweden's radiology departments perform virtual colonoscopy, but not for lack of interest in the procedure, a new study finds. Rather, the lack of multidetector CT scanners and training opportunities were the top reasons for not performing VC.

Vertebroplasty increases vertebral height, imaging shows
Literature shows that vertebroplasty reduces patients' pain. Yet there is ongoing debate about the cause and rate of new fractures found after the interventional procedure, and whether vertebroplasty alone can augment vertebral body height. Researchers from Germany tried to answer the last question by using preoperative MRI and postoperative CT.

CTA equivalent to angiography for detecting brain aneurysms
SAN FRANCISCO - One of the largest studies to date has also produced some of the highest sensitivities for the detection of ischemic stroke with CT angiography. In the study from the New Jersey Medical School, multidetector CT angiography (MDCTA) was all but equivalent to invasive catheter angiography for the detection of cerebral aneurysms in patients with subarachnoid hemorrhage.

Breast MRI offers clinicians a way to objectively measure BPE
By Kate Madden Yee
Breast MRI offers clinicians a way to objectively measure background parenchymal enhancement, or BPE -- which has been linked to increased breast cancer risk.
September 26, 2023
Examples of automatic fibroglandular tissue (FGT) segmentations on the precontrast (T1) non-fat saturated series and background parenchymal enhancement (BPE) extent on the postcontrast (T2) series for four control participants. For each participant, the left image shows the automated whole-breast segmentation (green line) and FGT segmentation (purple shading). The right image shows the areas of enhancement (red shading) within the FGT, defined as all voxels with 20% or more enhancement from the precontrast to postcontrast series. For each series, the middle section is presented. Example images were selected randomly within four categories defined by quantitative FGT volume (Vol) and BPE extent, where “low” refers to participants with measures in the bottom tertile and “high” refers to participants with measures in the top tertile. (A) Low FGT volume and low BPE extent in a 50-year-old premenopausal control participant. (B) Low FGT volume and high BPE extent in a 50-year-old control participant with a history of bilateral oophorectomy. (C) High FGT volume and low BPE extent in a 39-year-old premenopausal control participant. (D) High FGT volume and high BPE extent in a 44-year-old premenopausal control participant.
