PURPOSE Nonmelanoma skin cancers (NMSCs) are the most common type of human malignancy. Although surgical techniques are the standard treatment, radiation therapy using photons, electrons, and brachytherapy (BT) (radionuclide-based and electronic) has been an important mode of treatment in specific clinical situations. The purpose of this work is to provide(More)
PURPOSE Radiotherapy (RT) has played a significant role in treating non melanoma skin cancer (NMSC). High-dose-rate brachytherapy (HDR-BT) approaches have a paramount relevance due to their adaptability, patient protection, and variable dose fractionation schedules. Several innovative applicators have been introduced to the brachytherapy community. The(More)
The rat pars tuberalis was studied with conventional electron microscopy and immunocytochemistry for the demonstration of luteinizing hormone (LH). The LH-secreting cells were preferentially located in two regions of the pars tuberalis (PT), namely, that surrounding the neural stalk and that occupying the tuberoinfundibular sulci. Dialyzed extracts of PT(More)
The prenatal development of the normal diaphysis of the human long bone was studied through postmortem radiographs in 60 stillborns and 86 newborns of 20-41 weeks gestational age. Quantitative parameters were determined for the tibia, femur, and humerus. In all three long bones, significant positive correlations were found between the diaphyseal diameter,(More)
PURPOSE There are perineal templates for interstitial implants such as MUPIT and Syed applicators. Their limitations are the intracavitary component deficit and the necessity to use computed tomography (CT) for treatment planning since both applicators are non-magnetic resonance imaging (MRI) compatibles. To overcome these problems, a new template named(More)
PURPOSE The common use of nomograms in Low Dose Rate (LDR) permanent prostate brachytherapy (BT) allows to estimate the number of seeds required for an implant. Independent dosimetry verification is recommended for each clinical dosimetry in BT. Also, nomograms can be useful for dose calculation quality assurance and they could be adapted to High Dose Rate(More)
To better understand the intra-uterine bone modelling and remodelling process in small-for-gestational-age (SGA) newborn infants, long bone growth was studied using postmortem X-ray films in a group of such infants (n=34). Bone length, diaphyseal diameter, medullary diameter, cortical thickness, cortical area, the Barnett-Nordin index, and the percentage of(More)
PURPOSE T2 magnetic resonance imaging (MRI) is recommended as the imaging modality for image-guided brachytherapy. In locally advanced cervical carcinoma, combined endocavitary and interstitial applicators are appropriate (Vienna or Utrecht). To cover extensive disease, Template Benidorm (TB) was developed. Treatment planning system applicator libraries are(More)
PURPOSE SeedSelectron(®) v1.26b (Nucletron BV, The Netherlands) is an afterloader system used in prostate interstitial permanent brachytherapy with I-125 selectSeed seeds. It contains a diode array to assay all implanted seeds. Only one or two seeds can be extracted during the surgical procedure and assayed using a well chamber to check the manufacturer(More)
Gynaecologic brachytherapy (BT) is a fundamental part of the treatment of gynaecologic carcinomas, especially if it is not possible to perform surgery. Traditionally, low-dose-rate BT and planning by orthogonal X-rays have been used. Nowadays, high-dose-rate BT is available in most centres, enabling it to enhance the dose optimisation, radiation protection(More)
