The evaluation of radiation burden in vivo is crucial in modern radiology as stated also in the European Directive 2013/59/Euratom-Basic Safety Standard. Although radiation dose monitoring can impact the justification and optimization of radiological procedure, as well as effective patient communication, standardization of radiation monitoring software is far to be achieved. Toward this goal, the Italian Association of Medical Physics (AIFM) published a report describing the state of the art and standard guidelines in radiation dose monitoring system quality assurance. This article reports the AIFM statement about radiation dose monitoring systems (RDMSs) summarizing the different critical points of the systems related to Medical Physicist Expert (MPE) activities before, during, and after their clinical implementation. In particular, the article describes the general aspects of radiation dose data management, radiation dose monitoring systems, data integrity, and data responsibilities. Furthermore, the acceptance tests that need to be implemented and the most relevant dosimetric data for each radiological modalities are reported under the MPE responsibility.

Background: The dynamic progression of gray matter (GM) microstructural alterations following radiotherapy (RT) in patients, and the relationship between these microstructural abnormalities and cortical morphometric changes remains unclear.
Purpose: To longitudinally characterize RT-related GM microstructural changes and assess their potential causal links with classic morphometric alterations in patients with nasopharyngeal carcinoma (NPC).
Study Type: Prospective, longitudinal.

Targeted intraoperative radiotherapy (IORT) delivers a single dose of radiation to a fresh tumour bed immediately after lumpectomy, commonly used to treat early breast cancer (EBC). It is delivered during the same sitting, with improved patient compliance and better sparing of adjacent healthy tissue, compared to conventional adjuvant radiotherapy to the whole breast. The recently published 12-year results (median follow up of 8.

Sodium orthovanadate (vanadate), a potent inhibitor of p53, has been shown in earlier work to alleviate total-body irradiation (TBI)-induced hematopoietic syndrome. However, as p53 plays a crucial role in normal spermatogenesis, its suppression may raise concerns about potential adverse effects on male reproductive function. In this study, we investigated whether vanadate exacerbates impairment of male fertility when administered for hematopoietic protection under TBI conditions.

External exposure due to secondary photons (predominantly bremsstrahlung) generated from electron source emissions in environmental soil are of concern due to their ability to deposit significant amounts of ionizing energy to organs and tissues within the body. The "condensed history method" employed in many modern Monte Carlo (MC) codes may be used to simulate secondary photon yields (given as photons per beta decay) arising from electron source emissions with relatively few assumptions regarding the secondary photon spatial, energy, and angular dependencies. These yields may in turn be used to derive protection quantities such as secondary photon effective dose rate (DR) and risk coefficients for a variety of idealized external exposure scenarios.

Background: Percutaneous transthoracic lung biopsy (PTNB) guided by Computed Tomography (CT) greatly depends on the operators' skill for accuracy. This study aimed to evaluate whether three-dimensionally(3D) printed navigational templates for percutaneous transthoracic lung biopsy achieve diagnostic yield comparable to conventional computed tomography guidance.
Materials And Methods: Conducted from 1 November 2020, to 27 July 2023, this noninferiority randomized clinical trial included 159 patients with peripheral lung masses (≥30 mm).
