Right atrial thrombus complicating a right-sided arrhythmogenic cardiomyopathy.

There are few studies in the literature about arrhythmogenic cardiomyopathy complicated with right atrial thrombus. We report a case of right atrial thrombus complicating a right-sided arrhythmogenic cardiomyopathy detected by echocardiography. Electrocardiography showed typical Epsilon waves, and the diagnosis was further confirmed by cardiac magnetic resonance imaging.

Multisection computed tomography: Results from a Chinese survey on radiation dose metrics.

Background: As multisection spiral computed tomography (MSCT) have been extensively used, it is important to consider the amounts of doses the patients are exposed during a computed tomography (CT) examination. The aim of the current study was to summarize MSCT doses in Chinese patients to establish the diagnostic reference levels (DRLs).

Methods: Radiation dose metrics were retrospectively collected from 164,073 CT examinations via the Radimetrics Enterprise Platform.

Reducing the radiation dose with the adaptive statistical iterative reconstruction technique for chest CT in adults: a parameter study.

Background: Currently there is a trend towards reducing radiation dose while maintaining image quality during computer tomography (CT) examination. This results from the concerns about radiation exposure from CT and the potential increase in the incidence of radiation induced carcinogenesis. This study aimed to investigate the lowest radiation dose for maintaining good image quality in adult chest scanning using GE CT equipment.

Biological effects of low-dose radiation from computed tomography scanning.

Purpose: With the widespread use of computed tomography (CT), the risks of low-dose radiation from CT have been increasingly highlighted. This study aims to illustrate the CT-induced biological effects and analyze the potential beneficial or harmful outcomes so as to provide radiologists with reasonable advice on CT usage.

Materials And Methods: The related literature was analyzed according to the topics of stochastic effect, hereditary effect, deterministic effect, accumulative injuries, hormesis and adaptive response; population epidemiology data were also analyzed.
