Don't redo CT for mild head trauma if patient is stable

An initial CT exam after mild head trauma is a good idea because it can show bleeding in the brain. Repeating the scan, however, is unlikely to yield additional benefits or change management if the patient is stable, according to a new study in the January issue of Neurosurgery.

Resident program managers struggle to balance new demands

As program managers begin to implement far-reaching changes in radiology residency education, most believe they'll need to limit the options available to their residents to choose their own path -- particularly in the fourth year of training -- to ensure a good basic education for core residents, according to a survey presented at RSNA 2012.

NIH study: Cancer screening rates fall over decade

Cancer survivors on the lookout for secondary tumors maintained their traditionally high screening rates, but screening compliance by almost everyone else has declined over the past decade, according to a report published online December 27 in Frontiers in Cancer Epidemiology and Prevention.

Study finds CT radiation risk may be overestimated

The risks from testicular cancer far outweigh the radiation risk from CT exams used to diagnose and monitor it, concludes a study published today in Radiology. While the study was limited to testicular cancer, it illustrates a common mistake being made in estimating the risk of radiation from medical imaging exams.

Low-dose CT raises coronary calcium scores; IR corrects them

Low-dose coronary artery calcium (CAC) scores are reliable if iterative reconstruction (IR) is applied to the CT data, according to research presented at RSNA 2012. Dutch researchers found that the technology ensures the accuracy of CAC scores that would otherwise be higher and less predictable than the results of higher-dose CT scans.

MBIR finds same nodules as ASIR, at fraction of dose

Second-generation iterative reconstruction software doesn't necessarily improve radiologists' ability to detect lung nodules compared to earlier versions. But the new software permits the same lesion detection power at greatly reduced CT radiation doses, according to a study presented at last month's RSNA 2012 meeting in Chicago.

Time to ditch the chest x-ray, researchers conclude

CHICAGO - If cost isn't an issue -- and that's a big if -- it's time to say goodbye to chest radiography, say researchers from Norway who compared chest x-ray to ultralow-dose CT. Results were presented on Thursday at the 2012 RSNA meeting.

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.

Could AI scoring help with managing 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.

F-18 PSMA-1007 PET/CT of a 70 year old with newly diagnosed prostate cancer: PSA 770 ng/ml; Gleason 5 + 5; International Society of Urological Pathology grade 5. The maximum intensity projection images, CT, and fused images show PSMA ligand-avid prostate primary with pelvic, retroperitoneal, and mediastinal nodal spread. Additionally, he had left supraclavicular nodal metastasis (arrows).
