Relationship Between Effective Dose, Alternative Metrics, and SSDE: Experiences With Two CT Dose-Monitoring Systems [PDF]

Diagnostics
Background: We assessed the frequency and causes of discrepancies in CT dose indices such as dose-length product (DLP), size-specific dose estimate (SSDE), and effective dose (ED), as calculated by CT dose-monitoring systems.

Prospective estimation of water equivalent diameter and SSDE using 3D landmark CT scans. [PDF]

J Appl Clin Med Phys
Abstract Background 3D Landmark (3DLM) scans have recently been introduced in some new CT scanners for automatic scan planning instead of paired 2D localizers, with potential additional utility. Purpose The purpose of

Comparison of Size Specific Dose Estimates (SSDE) and CTDIvol Values in Patients Undergoing CT Examinations of Abdomen and Pelvis [PDF]

Radiography Open
Introduction: Computed Tomography Dose Index volume (CTDIvol) is a measure of radiation output of the CT scanner and does not represent patient dose.

Relationship between lacrimal gland changes and corneal parameters in patients with primary Sjögren’s syndrome and non-Sjögren’s syndrome-related dry eye [PDF]

Frontiers in Medicine
BackgroundPrimary Sjögren’s syndrome(pSS) is characterized as an autoimmune disorder mostly involving exocrine glands and pSS related dry eye (SSDE) contributes to a severe subtype of dry eye disease (DED).

A practical slice averaged image method for precise CT size specific dose estimates [PDF]

Scientific Reports
Computed tomography (CT) is a widely used diagnostic tool, but variations in patient anatomy make accurate radiation dose estimation challenging. While size-specific dose estimates (SSDE) can serve as a more effective tool for dose prediction than ...
