Dose‐Dependent Efficacy of Radioiodine Therapy in Pediatric Graves’ Disease: A Retrospective Study of Hypothyroidism Risk and the Predictive Role of Thyroid Hormone Parameters

iRADIOLOGY, EarlyView.
RAI therapy demonstrated time‐dependent efficacy in pediatric Graves' disease, with gradually increasing treatment success and hypothyroidism incidence during follow‐up. Higher planned activity (≥ 0.15 mCi/g) was associated with a higher successful rate than lower planned activity (< 0.15 mCi/g), and LASSO analysis identified FT3 and TSH as candidate ...

Mapping the Landscape of Over‐Scanning in CT Imaging: A Scoping Review

Journal of Medical Radiation Sciences, EarlyView.
Over‐scanning in CT is highly prevalent and contributes to unnecessary radiation exposure, with notable impact on radiosensitive organs. Standardised protocols and AI‐assisted planning show strong potential to optimise scan range and reduce excess dose.

THE EURADOS WORK TOWARDS A REVIEW ON RETROSPECTIVE DOSIMETRY AFTER INCORPORATION OF RADIONUCLIDES

, 2019
Biological dosimetry methods are well established and validated for providing dose estimates following external radiation exposures. In contrast, interpreting biological dosimetry data in cases of internal exposures is still challenging. In this context,

MIBG Therapy for Neuroblastoma: Precision Achieved With Dosimetry, and Concern for False Responders

Frontiers in Medicine, 2020
Neuroblastoma causes 15% of cancer mortality in children. High risk neuroblastoma has poor prognosis, with high relapse rate and mortality despite multimodal treatment.

Prone Breast Radiotherapy on the MR‐Linac: A Technical Note on Skin‐Couch Contact Dose Effects

Journal of Medical Radiation Sciences, EarlyView.
This retrospective planning study evaluated the dosimetric effects of skin‐couch contact during prone APBI on a 1.5 T MR‐Linac by comparing treatment plans calculated with and without a magnetic field. While the presence of the magnetic field increased overall superficial skin dose, it consistently reduced dose at the skin‐couch contact region ...

Idac-alpha An alpha dosimetry software for normal organs and tissues

, 2021
Radiopharmaceuticals have been used for the treatment of various forms of cancer since the 1940s. In recent years, the advantages of alpha emitting radionuclides have emerged as a favourable treatment option.

Dosimetry, Toxicity and Stability Associated With a Hyaluronic Acid‐Based Prostate‐Rectal Spacing Device During Prostate Radiation Therapy: A Retrospective Comparative Analysis

Journal of Medical Radiation Sciences, EarlyView.
Rectal spacers composed of stabilised hyaluronic acid facilitated a favourable toxicity profile compared to no spacing during prostate radiation therapy. Acute GI toxicity (grade ≥ 1) was lower in the spacer cohort (23.5% vs. 48.0%; odds ratio = 0.33, p = 0.05) with grade ≥ 2 toxicity substantially lower (2.9% vs. 20.0%).

Possibilities of using human teeth for retrospective dosimetry: Analysis of the Techa river data

, 2007
Different methods for utilising teeth were applied for the reconstruction of internal and external doses for the population of the Techa riverside area contaminated as a result of radioactive releases from the Mayak plutonium-production facility ...

Evaluation of biokinetics and dosimetry in [131I]-NaI therapies: whole-body images quantification versus lower limb region

Brazilian Journal of Radiation Sciences, 2020
Introduction: Radioiodine therapy with iodine-131 (131I) is the most commonly performed radionuclide therapy in Nuclear Medicine[1]. When used in the treatment of differentiated thyroid cancer (DTC), it consists in the administration of a quantity of ...

Size‐specific dose estimates calculated using patient size measurements from scanned projection radiograph in high‐resolution chest computed tomography

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 85-92, March 2025.
This study established that patient's lateral width measurements made from scanned projection radiograph (SPR) is an overestimate compared to those measured from tomographic slices by about 10%. Size‐specific dose estimates (SSDE) calculated using lateral width measured from SPR correlates well with SSDE calculated using water equivalent diameter of ...
