Statistical-based modeling strategy for entrance skin dose estimation in patient undergoing body interventional radiology.
Radiat Prot Dosimetry

Nuclear and Ionizing Radiation Metrology Section, Office of Atoms for Peace, Bangkok 10900, Thailand.
Interventional radiology (IR) provides significant advancements in diagnostic and therapeutic procedures, yet concerns persist regarding radiological risks such as erythema, burns, and epilation. Direct dose measurements observed difficulties regarding the perturbation of the detector probe in X-ray images during fluoroscopy-guided procedures, high-cost expenses, and non-compliant patients. This study aims to develop a statistical-based model for estimating entrance skin dose (ESD) in body IR procedures using patient radiation-dose recording data.

Introduction: The aim of this study is to quantify the association of temporary epilation following interventional neuroradiology (INR) procedures and compare the peak skin dose (D) threshold to published values.
Methods: Gold Coast University Hospital (GCUH) is a major centre for INR with over 500 primarily interventional procedures performed every year. D is calculated when the reference air kerma (K) exceeds 3 Gy.

A 17-month-old domestic short-hair cat was referred due to a non-union in the left tibia. The initial repair, conducted 3 months prior at another animal hospital, involved an intramedullary (IM) pin and wire to address a comminuted fracture. Unfortunately, the wire knot caused a skin tract, resulting in osteomyelitis.

Endoscopic removal of trichobezoars is challenging, and these masses often require surgical removal. Recently, although it has been reported that Coca-Cola could effectively dissolve persimmon phytobezoars, it was ineffective in dissolving trichobezoars.

Background: Physicians use fixed C-arm fluoroscopy equipment with many interventional radiological and cardiological procedures. The associated effective dose to a patient is generally considered low risk, as the benefit-risk ratio is almost certainly highly favorable. However, X-ray-induced skin injuries may occur due to high absorbed patient skin doses from complex fluoroscopically guided interventions (FGI).
