Two cases of tumours arising in or near the pancreatic head are reported in patients previously treated with abdominal irradiation for testicular tumours. These are only the third and fourth such cases to be reported and they suggest that second cancers may develop as a result of abdominal irradiation for malignant disease.

Evaluation of Male Gonadal Radiation Dose in Abdominal X-ray Examinations: The Impact of Radiographic Projections and Kilovoltage Peak (kVp).

In abdominal X-ray examinations, radiosensitive organs such as the gonads within or near the imaging region are at risk of radiation exposure. Minimizing the dose to these organs is crucial to reducing unnecessary radiation. This study utilized optically stimulated luminescence dosimeters (OSLDs) to measure the radiation dose to the male gonads at varying kilovoltage peak (kVp) settings while keeping the milliampere-seconds (mAs) constant across different radiographic projections.

Purpose: We provide for the first time a comprehensive situational diagnosis and propose an artificial intelligence (AI)-assisted nationwide plan of implementation, attending the most urgent needs.
Methods: Baseline information was collected from open-source databases of the Peruvian Government. Data on cancer incidence from the Health Authorities and GLOBOCAN were collected and compared.
Abdominal synthetic CT generation for MR-only radiotherapy using structure-conserving loss and transformer-based cycle-GAN.

Purpose: Recent deep-learning based synthetic computed tomography (sCT) generation using magnetic resonance (MR) images have shown promising results. However, generating sCT for the abdominal region poses challenges due to the patient motion, including respiration and peristalsis. To address these challenges, this study investigated an unsupervised learning approach using a transformer-based cycle-GAN with structure-preserving loss for abdominal cancer patients.

Objectives: Implementing pre-treatment patient-specific quality assurance (prePSQA) for cancer patients is a necessary but time-consuming task, imposing a significant workload on medical physicists. Currently, the prediction methods used for prePSQA fall under the category of supervised learning, limiting their generalization ability and resulting in poor performance on new data. In the context of this work, the limitation of traditional supervised models was broken by proposing a conditional generation method utilizing unsupervised diffusion model.
