Estimation of patient effective doses in PET/CT- F-Sodium Fluoride examinations.

The positron emitters (F-Sodium Fluoride (NaF)) and X-rays used in Positron emission tomography (PET) combined with computed tomography (PET/CT) imaging have a high radiation dose, which results in a high patient dose. The present research intends to determine the radiation dose and risks associated with PET/CT- 18F-Sodium fluoride examinations in patients. The 18F-NaF PET/CT was used to investigate the doses of 86 patients.

National Diagnostic Reference Levels for Nuclear Medicine in Kuwait.

The diagnostic reference level (DRL) is a patient-exposure optimization tool used to evaluate and provide guidance for radiation doses in medical imaging. In the past few decades, there has been a global increase in the number of diagnostic imaging procedures, including nuclear medicine procedures, and consequently in patient radiation exposure. This increase has encouraged international and national health-care organizations to take action and keep up with such changes to meet the expectation of increasing use of ionizing radiation in medicine.

Assessment of eye doses to staff involved in interventional cardiology procedures in Kuwait.

In this study, which is the first of its kind in the gulf region, eye doses of interventional cardiologists and nurses were measured using active dosimeters for left and right eyes, in 60 percutaneous coronary interventions in three main hospitals in Kuwait. The dose given in terms of H(0.07) per procedure when ceiling suspended screens were used by main operators ranged from 18.

The clinical effectiveness of reconstructing F-sodium fluoride PET/CT bone using Bayesian penalized likelihood algorithm for evaluation of metastatic bone disease in obese patients.

Objective: A new Bayesian penalized likelihood reconstruction algorithm for positron emission tomography (PET) (Q.Clear) is now in clinical use for fludeoxyglucose (FDG) PET/CT. However, experience with non-FDG tracers and in special patient populations is limited.

Patient Exposure during Fluoroscopy-guided Pacemaker Implantation Procedures.

A pacemaker, which is used for heart resynchronization with electrical impulses, is used to manage many clinical conditions. Recently, the frequency of pacemaker implantation procedures has increased to more than 50% worldwide. During this procedure, patients can be exposed to excessive radiation exposure.
