Study information
| Study design | Randomised controlled trial |
|---|---|
| Primary study design | Interventional |
| Secondary study design | Randomised controlled trial |
| Study setting(s) | Hospital |
| Study type | Diagnostic |
| Scientific title | |
| Study hypothesis | Demonstrate a reduction in patient exposure/dose commensurate with no negative impact on diagnosis by removing antiscatter grid. |
| Ethics approval(s) | Not provided at time of registration |
| Condition | Coronary artery disease |
| Intervention | Patients referred for diagnosis of coronary artery disease and with a Body Mass Index of less than 40 will be randomised into two groups. One group will receive the standard technique with grid, the other group will receive the modified (lower skin dose) technique without the grid. Post diagnosis images acquired will be double blindly reviewed for image quality. |
| Intervention type | Other |
| Primary outcome measure | 1. Successful diagnosis of disease 2. Lower skin dose to the patient 3. Lower exposure to members of staff monitored during the trial as the employer is required to do by IRR1999 regulation 8(1) |
| Secondary outcome measures | Not provided at time of registration |
| Overall study start date | 28/01/2004 |
