dentin dysplasia is an exceptionally rare, autosomal-dominant, hereditary condition, primarily characterized by defective dentin formation affecting both the deciduous and permanent dentitions. the etiology remains imprecise to date, in spite of the numerous hypotheses put forward and the constant updates on this condition. this case report of type i dentin dysplasia exhibits radiographic fi nd...

Introduction Prostate brachytherapy by Iodine-125 seeds is a common treatment modality for localized prostate cancer. An important aspect in such a treatment is intra-operative and post-implant dose evaluation, which relies on accurate localization of implanted seeds relative to the surrounding organs. In current clinical practice, the seeds are localized intra-operatively using ultrasonography...

Recently, elongated brachytherapy sources (active length >1 cm) have become commercially available for interstitial prostate implants. These sources were introduced to improve the quality of brachytherapy procedures by eliminating the migration and seed bunching associated with loose seed-type implants. However, the inability to calibrate elongated brachytherapy sources with the Wide-Angle Free...

In the recommendations of Task Group #43 from American Association of Physicists in Medicine (AAPM TG43), methods of brachytherapy source dosimetry are recommended, under full scattering conditions. However, in actual brachytherapy procedures, sources may not be surrounded by full scattering tissue in all directions. Clinical examples include high-dose-rate (HDR) brachytherapy of the breast or ...

BACKGROUND To retrospectively evaluate the outcome of patients with inoperable non-small-cell lung cancer treated with primary external beam radiotherapy combined with high-dose-rate endobronchial brachytherapy boost. PATIENTS AND METHODS Between 1988 and 2005, 35 patients with non-small-cell lung cancer (stage I-III) ineligible for surgical resection and/or chemotherapy, were primarily treat...

background: accelerated partial breast irradiation via interstitial balloon brachytherapy is a fast and effective treatment method for certain early stage breast cancers however skin, chest wall and lung doses are correlated with toxicity in patients treated with breast brachytherapy. objective: to investigate the percentage of the dose received by critical organ (skin), thermoluminescence dete...

Purpose In interstitial brachytherapy for lung tumors, the placement and alignment of the source needles are influenced by the ribs, which can affect the dose distribution. This study evaluated the change in dose to the target by comparing the dose between the actual interstitial brachytherapy plan (AIBP, what is deliverable due to anatomic constraints), and the virtual interstitial brachythera...
