Diagnostic reference levels and median doses for common clinical indications of CT: findings from an international registry
ConclusionsDRLs for CTDIvol and DLP for EUCLID clinical indications from diverse organizations were established and can contribute to dose optimization. These values were usually significantly higher in the US than in Europe.Key Points•Registry data were used to create benchmarks for 10 common indications for CT identified by the European Society of Radiology.•Observed US radiation doses were higher than European for 9 of 10 indications (except chronic sinusitis).•The presented diagnostic reference levels and median doses highlight potentially unnecessary variation in radiation dose.

Cerebellar Stroke and Leptomeningeal Carcinomatosis following Cement Leakage into the Vertebral Artery during Cervical Vertebroplasty
This report describes an unusual vertebral artery cement embolization during C3 transpedicular vertebroplasty performed under computed tomography (CT) guidance and fluoroscopy. The Institutional Review Board approved this case report, and the patient ’s consent for publication was obtained. A 54-year-old woman with an invasive lobular breast carcinoma suffered from cervical pain. A CT scan showed spinal osteolytic lesions. A thoracic vertebral biopsy confirmed the diagnosis of breast cancer metastasis.

CT diagnostic reference levels based on clinical indications: results of a large-scale European survey
ConclusionsThis is the first study reporting on feasibility of establishing CT DRLs based on CI using European data. Resulting values will serve as a baseline for comparison with local radiological practice, national authorities when DRLs are set/updated, or as a guideline for local DRL establishment.Key Points•First study reporting on the feasibility of establishing CT diagnostic reference levels based on clinical indication using data collected across Europe.•Only one-fourth of the hospitals had CT machines less than 5 years old.•Large dose variations were observed among hospitals and CT protocols were quite differ...

ACR Preliminary Summary of Radiology Provisions in the 2017 MPFS Proposed Rule
The Centers for Medicare and Medicaid Services (CMS) released the Medicare Physician Fee Schedule (MPFS) proposed rule on Thursday, July 7. Upon initial review, the American College of Radiology (ACR) is pleased with several provisions within the rule. CMS has recognized the value provided by radiologists in providing mammography services through an increase in the physician work relative value units (RVUs) for diagnostic mammography and maintaining the current value for screening mammography. Additionally, ACR physicians and staff held numerous conference calls and meetings with CMS on the topic of appropriate use criteri...
