Effects of Kilovoltage on Image Quality and Entrance Surface Dose in Lumbar Spine Digital Radiography
Introduction: Digital radiography possesses a wide dynamic range and has a major advantage in producing an acceptable image of diagnostic value even though overexposure occurs. Lumbar spine (LS) radiography is the most common examinations that gives high radiation dose to patients and accounts for the highest collective population dose of any conventional radiographic ...
متن کاملBeam Collimation during Lumbar Spine Radiography: A Retrospective Study
Introduction: Collimating the primary beam to the area of diagnostic interest (ADI) has been strongly recommended as an effective method to reduce patient’s radiation dose and to improve image quality during radiology practice. Lack or inadequate collimation results in excessive radiation dose to patients and deterioration image quality.Objective: To assess the quality of beam collimation dur...
متن کاملInvestigation of the Entrance Surface Dose and Dose to Different Organs in Lumbar Spine Imaging
Background: Dose assessment using proper dosimeters is especially important in radiation protection optimization and imaging justification in diagnostic radiology.Objective: The aim of this study is to obtain the Entrance Skin Dose (ESD) of patients undergoing lumbar spine imaging using two thermoluminescence dosimeters TLD-100 (LiF: Mg, Ti) and GR-200 (LiF: Mg, Cu, P) and also to obtain the ab...
متن کاملSpinal Anesthesia in Elderly Patients Undergoing Lumbar Spine Surgery.
Spinal anesthesia is increasingly viewed as a reasonable alternative to general anesthesia for lumbar spine surgery. However, the results of spinal anesthesia in elderly patients undergoing lumbar spine decompression and combined decompression and fusion procedures are limited in the literature. The aim of this study was to report a single institution's experience using spinal anesthesia in eld...
متن کاملThe effect of breast shielding during lumbar spine radiography
BACKGROUND The aim of the study was to determine the influence of lead shielding on the dose to female breasts in conventional x-ray lumbar spine imaging. The correlation between the body mass index and the dose received by the breast was also investigated. MATERIALS AND METHODS Breast surface dose was measured by thermoluminescent dosimeters (TLD). In the first phase measurements of breast d...
