Regression Patterns of Iris Melanoma after Palladium-103 (103Pd) Plaque Brachytherapy.
PURPOSE To evaluate the patterns of regression of iris melanoma after treatment with palladium-103 (103Pd) plaque brachytherapy. DESIGN Retrospective, nonrandomized, interventional case series. PARTICIPANTS Fifty patients with primary malignant melanoma of the iris. METHODS Palladium-103 plaque brachytherapy. MAIN OUTCOME MEASURES Changes in tumor size, pigmentation, and vascularity; in...
متن کاملCLINICAL SCIENCES Palladium 103 (Pd) Plaque Radiation Therapy for Circumscribed Choroidal Hemangioma With Retinal Detachment
Methods: One course of Pd ophthalmic plaque radiotherapy was used in each of 5 patients with circumscribed choroidal hemangioma who had progressive loss of vision due to subretinal exudation. A mean apex dose of 2900 cGy (2900 rad) was delivered. Functional tests of outcome included best-corrected visual acuity. Anatomic results included changes in tumor height and subretinal fluid documented b...
متن کاملCyclotron production of no-carrier-added palladium-103 by bombardment of rhodium-103 target.
Electroplated rhodium foil was employed as the target for cyclotron production of palladium-103. An electrodissolution apparatus was found better than other dissolution methods in terms of personnel shielding and palladium-103 yield. The ion-exchange column chromatography method was simple and effective for the purification of palladium-103 and the final stripping agent of NH4Cl + NH3(1:1) was ...
متن کاملPalladium-103 plaque radiation therapy for macular degeneration: results of a 7 year study.
AIM To report 7 year results of ophthalmic plaque radiotherapy for exudative macular degeneration. METHODS In a phase I clinical trial, 30 patients (31 eyes) were treated with ophthalmic plaque irradiation for subfoveal exudative macular degeneration. Radiation was delivered to a mean 2 mm from the inner sclera (range 1.2-2.4) prescription point calculated along the central axis of the plaque...
متن کاملExperimental and Monte Carlo dosimetric characterization of a 1 cm (103)Pd brachytherapy source.
PURPOSE To determine the in-air azimuthal anisotropy and in-water dose distribution for the 1 cm length of a new elongated (103)Pd brachytherapy source through both experimental measurements and Monte Carlo (MC) simulations. Measured and MC-calculated dose distributions were used to determine the American Association of Physicists in Medicine Task Group No. 43 (TG-43) dosimetry parameters for t...
