Automatic Dose Reduction Should Not Mask Needs for Individual Dose Reduction
Radiology, 2004Editor: We read with interest the article of Dr Mastora and colleagues in the January 2004 of Radiology (1), regarding radiation dose reduction with the use of anatomically adapted online tube current modulation in the evaluation of the thoracic outlet.

CT is undoubtedly a powerful diagnostic tool, but data from surveys of CT practice show that, over the 30 years of clinical use, CT has contributed an ever-increasing percentage to the population dose from medical X-ray examinations [1, 2]. Although some regard the radiation dose levels from CT as beneficial [3], the generally held view is one of alarm

Dose reduction in dental radiography
Journal of Dentistry, 1990All exposures to ionizing radiation for medical and dental purposes carry risks to both the patient and staff. It is now accepted practice that all exposures should be kept as low as reasonably practicable to minimize these risks. The various methods currently available for dose limitation in intraoral and panoramic radiography and their effects on ...

Dose Reduction in Tomosynthesis of the Wrist
American Journal of Roentgenology, 2017The purpose of this study was to quantitatively and qualitatively determine the impact of radiation dose reduction on the image noise and quality of tomosynthesis studies of the wrist.Imaging of six cadaver wrists was performed with tomosynthesis in anteroposterior position at a tube voltage of 60 kV and tube current of 80 mA and subsequently at 60 or ...

Simulation of dose reduction in tomosynthesis
Medical Physics, 2009Purpose: Methods for simulating dose reduction are valuable tools in the work of optimizing radiographic examinations. Using such methods, clinical images can be simulated to have been collected at other, lower, dose levels without the need of additional patient exposure.

Dose reduction in evacuation proctography
European Radiology, 2001The goal of this study was to reduce the patient radiation dose from evacuation proctography. Ninety-eight consecutive adult patients referred for proctography to investigate difficult rectal evacuation were studied using a digital imaging system with either a standard digital program for barium examinations, a reduced dose digital program (both with ...

Dose reduction fluoroscopy in pediatrics
Pediatric Radiology, 2002It is essential that we find ways to reduce radiation exposure to children and maintain image quality.We compared radiation dose, image quality, and spatial resolution when continuous and pulse fluoroscopy with a full and half dose are applied to a phantom.

A device for the reduction of population dose
Oral Surgery, Oral Medicine, Oral Pathology, 1982Conventional dental radiographic procedures do not permit direct visualization of the radiation field or the central ray. As a result, it is necessary to use a beam diameter larger than the film in order to prevent an unnecessarily high number of cone cuts or other errors during visual alignment of the cone and film.

Pediatric Radiology, 2011
Greater than 10% of diagnostic imaging studies performed in developed countries are CT examinations. In the United States, as many as 60 million CT studies are performed each year, up to 7 million of which are performed in pediatric patients. In the spirit of the ALARA principle, both adult and pediatric radiologists should strive to decrease pediatric

High-Dose Treatment With Haloperidol: The Effect of Dose Reduction
Journal of Clinical Psychopharmacology, 2000High doses of antipsychotic medications are sometimes prescribed in clinical practice, although the efficacy and safety of such treatment have not been established. The purpose of this study was to determine whether high-dose, long-term antipsychotic treatment prescribed on the basis of clinical judgment can be justified.
