Size specific dose estimate (SSDE) for estimating patient dose from CT used in myocardial perfusion SPECT/CT
Objective(s): Size specific dose estimate (SSDE) is a new parameter that includes patient size factor in its calculation. Recent studies have produced mixed results on the utility of SSDE, especially when automatic exposure control (AEC) was used. The objective of the study was to find out if there is a relationship between patient size and each of the parameters, SSDE...
متن کاملUsing GafChromic film to estimate the effective dose from dental cone beam CT and panoramic radiography.
OBJECTIVES To demonstrate the feasibility of GafChromic(®) XR-QA2 (ISP Corp., Wayne, NJ) as a dosemeter when performing measurements of the effective dose from three cone beam CT (CBCT) units and to compare the doses from examinations of three common dental clinical situations. A second aim was to compare the radiation doses for three digital panoramic units with the doses for the CBCT units. ...
متن کاملHow to Appropriately Calculate Effective Dose for CT Using Either Size-Specific Dose Estimates or Dose-Length Product.
OBJECTIVE The purpose of this study is to show how to calculate effective dose in CT using size-specific dose estimates and to correct the current method using dose-length product (DLP). MATERIALS AND METHODS Data were analyzed from 352 chest and 241 abdominopelvic CT images. Size-specific dose estimate was used as a surrogate for organ dose in the chest and abdominopelvic regions. Organ dose...
متن کاملApplication of Dose-Area Product compared with three other dosimetric quantities used to estimate patient effective dose in diagnostic radiology
Background: Application of Dose-area product (DAP) quantity has been increased in the clinical practice. DAP is relatively easy to measure. DAP has been shown to correlate well with the total energy imparted to the patient, which is related to the effective dose. Material and Methods: In this study, measurements of DAP were carried out in a sample of 421 adult patients who underwent convention...
متن کاملUnnecessary Brain CT scan of Traumatic Pediatric Patients; How to Reduce the Numbers?
There are considerable rates of pediatrics trauma referring emergency department following a traumatic event. The worried parents are requesting for the most sensitive diagnostic test, so emergency physicians ask them to underwent brain computed tomography (CT) scan. Lower threshold of decision making regarding use of brain CT scan results in huge number of normal imaging. On the other hand, ra...
