FDA clears Mobius Imaging ’ s Airo Mobile CT imager for pediatric use
Mobius Imaging said yesterday it won FDA 510(k) clearance for its Airo Mobile CT imaging system designed for pediatric applications. The Shirley, Mass.-based company said it previously won FDA 510(k) clearance in 2013 for non-pediatric imaging, and is designed for use in applications supporting brachytherapy, radiation therapy and surgical imaging. The new clearance is an important milestone for the company, Mobius said, expanding the use of the Airo CT system into new segments and applications. “There is an unmet need in being able to provide safe and reliable CT imaging for pediatric patients during various clinical procedures. CT systems must be designed and validated for safety and efficacy using different protocols than would be appropriate for adult patients. We are delighted to now be able to offer the benefits of Airo Mobile CT imaging to clinicians and their pediatric patients,” Mobius Imaging CEO Gene Gregerson said in a prepared statement. The post FDA clears Mobius Imaging’s Airo Mobile CT imager for pediatric use appeared first on MassDevice.
Objectives: Lymphovascular space invasion (LVSI) is a known prognostic factor for endometrial carcinomas. However, LVSI as a determinant of treatment benefit has not been fully elucidated. Methods and Materials: Data from the National Cancer Database for endometrial cancer from 2004 to 2012 was obtained. Univariate and multivariate analysis was performed to assess the impact of LVSI on overall survival (OS). Survival analysis was performed utilizing log-rank and Kaplan-Meier analyses. The difference in OS between external beam radiation therapy (EBRT) and vaginal brachytherapy (VBT) in LVSI-positive patients was analy...
Conclusions: The clinical results suggest that IMRT concurrent with chemotherapy isan effective treatment with acceptable toxicity for advanced cervical cancer with positive lymph nodes.
Using in vivo measurements from optically stimulated luminescence dosimeters (OSLDs) to develop and validate a prediction model for estimating the skin dose received by patients undergoing breast intraoperative radiation therapy (IORT).
This study aimed to compare external radiation (beam radiation) and internal radiation as a single radiation therapy to advanced HCC patients (TNA stage III and IV according to the derived AJCC Stage, 6th edition) stratified by other risk factors, based on the data collected from the Surveillance, Epidemiology and End Results (SEER) national database. In this cohort study, we mainly clarified the following three points: 1. Choices of radiation therapy for advanced HCC patients vary in demographic and clinical factors. Among these, TNM classification is the key factor. 2. Internal radiation provides a better prognosis in bo...
CONCLUSIONS: The first results of treatment with the Axxent eBT device are promising, as no recurrences have been observed and toxicity is very low. eBT is a good alternative for treating cervical cancer in centers without access to conventional HDR.

Conclusions: DIR is increasingly important in RT applications, from planning to toxicity prediction. DIR is routinely used to reduce the workload of contour propagation. However, its use for complex dosimetric applications must be carefully evaluated by combining quantitative and qualitative analyses. PMID: 31155990 [PubMed - as supplied by publisher]

Conclusions: Percutaneous CT fluoroscopy-guided permanent seed brachytherapy is a safe, efficacious, and cost effective primary and salvage treatment for lung cancer. CT-fluoroscopy resources are readily available in the community and are an effective alternative to stereotactic body radiation therapy (SBRT), intensity-modulated radiation therapy (IMRT)/proton beam, radiofrequency ablation (RFA), and cryoablation (CA). Percutaneous CT fluoroscopy-guided permanent seed brachytherapy has an equivalent or better local control rate, a lower resource cost, and a far lower integral radiation dose than other therapies. We believe...
Conclusion: The proposed QSM-based technique relies on the standard MR pulse sequences and visualize the conventional MR-invisible metallic devices with CT-like positive contrast solely through post-processing. Upon in-vivo validation of the technique, QSM may have the potential to replace CT for an MR-only guided radiation therapy.
