High dose-rate (HDR) brachytherapy (BT) is commonly used to treat prostate and cervical cancer by irradiating the target volume using dedicated applicators and/or catheters. BT offers sharp dose gradients which may lead to decreased dose to organs at risk compared to external beam radiotherapy.[1,2] Image-guided implant reconstruction has become standard practice, using medical imaging such as CT, MR or ultrasound acquired before treatment planning.[3,4] After reconstructing the applicator and/or interstitial catheters, a treatment plan is created using the target and organ at risk delineations by optimizing dwell times in...

This article summarizes the existing literature and discusses the emerging role of hybrid PET/MRI in gynecologic malignancies. Thus, far, the published literature on the applications of FDG PET/MRI shows that it can have a significant impact on patient management by improving the staging of the cancers compared with PET/CT, influencing clinical decision and treatment strategy. For disease restaging, current literature indicates that PET/MRI performs equivalently to PET/CT. There appears to be a mild-moderate inverse correlation between standard-uptake-value (SUV) and apparent-diffusion-coefficient (ADC) values, which could...

Herein, a Harris corner detection algorithm is proposed based on the concepts of iterated threshold segmentation and adaptive iterative threshold (AIT–Harris), and a stepwise local stitching algorithm is used to obtain wide-field ultrasound (US) images. Cone-beam computer tomography (CBCT) and US images from 9 cervical cancer patients and 1 prostate cancer patient were examined. In the experiment, corner features were extracted based on the AIT–Harris, Harris, and Morave algorithms. Accordingly, wide-field ultrasonic images were obtained based on the extracted features after local stitching, and the corner mat...

ConclusionTVSE has a relatively high and satisfactory value for differential diagnosis between malignant and benign cervical lesions. The diagnostic performance of strain elastography and shear wave elastography were similar and good. However, to accommodate heterogeneity and publication bias, high ‐quality studies are required to further comparative effectiveness analyses to verify the efficacy of ultrasound detection.

DISCUSSION: A comprehensive neck ultrasound in thyroid cancer patients, performed by their endocrine surgeon, could enhance management planning and outcomes. This finding highlights the critical need for education and improvement of routine neck ultrasonographic examination performed in the community. PMID: 32853031 [PubMed - as supplied by publisher]

to Tomohiro Osaki The combined administration of microbubbles and ultrasound (US) is a promising strategy for theranostics, i.e., a combination of therapeutics and diagnostics. Lipid bubbles (LBs), which are experimental theranostic microbubbles, have demonstrated efficacy in vitro and in vivo for both contrast imaging and drug delivery in combination with US irradiation. To evaluate the clinical efficacy of LBs in combination with US in large animals, we performed a series of experiments, including clinical studies in dogs. First, contrast-enhanced ultrasonography using LBs (LB-CEUS) was performed on the livers of s...
