Prospective intra/inter-observer evaluation of pre-brachytherapy cervical cancer tumor width measured in TRUS and MR imaging

Ultrasound (US) imaging has been proved as an excellent diagnostic tool in gynecology and, due to its wide availability and limited cost, is under intense investigation as base for dose adaptation in cervical ...

Abstract The purpose of this article was to report the treatment effect of image-guided high-dose-rate interstitial brachytherapy boost in the radical radiotherapy for a huge metastatic carcinoma of cervical lymph nodes from an unknown primary site. The patient was a 75-year-old male. A diagnostic biopsy showed metastatic squamous cell carcinoma and the tumour size was 7.5×6.5×11.5cm3 before treatment (N3; AJCC 7th). After external beam radiotherapy with a dose of 60Gy in 30 fractions, the residual tumour (6.2×4.7×6.0cm3) was treated with image-guided high-dose-rate interstitial brachythera...

Cervical cancer is one of the most common cancers that affect women. One of the most effective ways of treating cervical cancer is brachytherapy. The dose in cervical brachytherapy is delivered with the use of an applicator that is placed during an operation through the vaginal canal to reach the cervix area. The dose in then delivered with the use of an after- loading system. The dose delivery is heavily reliant on the position of the applicator.Although ultrasound is used to provide information about the position of the applicator during the insertion process, in most cases the applicator is not visible on the ultrasound images.

Abstract PURPOSE: To estimate uterine perforations rates during intracavitary brachytherapy for cervical cancer with and without ultrasound (US) image guidance. MATERIALS AND METHODS: A systematic search of databases (PubMed and EMBASE) was performed. The pooled summary uterine perforation rate (detected by postinsertion CT or MRI) for the un-guided insertion group and the guided insertion group was calculated by using the random-effects model weighted by the inverse variance. RESULTS: A total of 690 articles were initially found, resulting in 12 studies that met the inclusion criteria. A total of 1757 i...

Doppler ultrasound (US) gives real-time information regarding anatomy and blood vessel location to guide needle placement for gynecologic interstitial brachytherapy (BT). We retrospectively assessed Doppler US images for vessel quantity, size, and distribution in cervical cancer patients undergoing high dose rate (HDR) BT at our institution.

Abstract Imaging has probably been the most important driving force for the development of brachytherapy treatments the last 20 years. Due to implementation of three-dimensional imaging, brachytherapy is nowadays a highly accurate and reliable treatment option for many cancer patients. To be able to optimize the dose distribution in brachytherapy the anatomy and the applicator(s) or sources should be correctly localised in the images. For computed tomography (CT) the later criteria is easily fulfilled for most brachytherapy sites. However, for many sites, like cervix and prostate, CT is not optimal for delineation...
