Deep Learning-Based Segmentation of Head and Neck Organs-at-Risk with Clinical Partially Labeled Data

Entropy, 2022
Radiotherapy is one of the main treatments for localized head and neck (HN) cancer. To design a personalized treatment with reduced radio-induced toxicity, accurate delineation of organs at risk (OAR) is a crucial step.

Solid Pseudopapillary Neoplasm of the Pancreas in Children and Adolescents: Expert Recommendations

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Solid pseudopapillary neoplasm of the pancreas (SPN) is a rare low‐grade malignant exocrine pancreatic tumor, mostly discovered during the second decade of life in females, with a very good prognosis, provided microscopically complete surgical excision is achieved.

Dose distribution in organs at risk.

, 2015
Doses [Gy] in organs at risk of all patients for 30 treatment fractions are demonstrated. Maximum shielding of the eyeballs resulted in mean doses in the optic nerves from 1.19 Gy to 46.18 Gy (max 63.44, min 0,88 Gy).
