IMPORTANT: All items in bold in the Technique Parameters and Anatomic Coverage sections below are required to successfully achieve accreditation. CTDIvol information is required for each study. Either include a screen save of the dose with the images, or enter the dose as displayed by the scanner in the Clinical Test Image Data Sheet. Upload the primary reconstructed images used for diagnostic interpretations; include the scout(s) and dose report. Do NOT submit the sagittal, coronal and extra thin images unless specifically listed under required series.
IMPORTANT: ***Currently many DE units have the ability to post process a non-contrast series from the acquired contrast series. This virtual non-contrast series is acceptable to submit as part of accreditation review for the adult liver, adult pancreas or adult renal exams.
Adult Abdomen(This is a uniphasic exam submission. If submitting a multiphasic exam, consider one of the other exam choices.) |
Technique Parameters |
Required Series | IV Contrast Enhanced timed to portal venous phase. |
Reconstructed Slice Width | ≤ 5 mm |
Reconstruction Algorithm | Standard or soft tissues, or appropriate body kernel |
Oral Contrast | It is recommended oral contrast material be present with barium or neutral (water) contrast agents |
CTDIvol | Reference value: 25 mGy; Pass/Fail criteria: 30 mGy (CTDIvol guidance is based on a single series or uniphasic exam for a standard size patient) |
Anatomical Coverage |
Coverage | Diaphragm to iliac crest to include the entire liver; May include pelvis |
Adult Liver Study |
Technique Parameters |
Required Series | Non-contrast*** and IV contrast enhanced study to include arterial and portal venous phase series |
Reconstructed Slice Width | ≤ 3 mm |
Reconstruction Algorithm | Standard or soft tissue (or appropriate body kernel) |
Oral Contrast | Not required |
CTDIvol | There are no reference values for this examination |
Anatomical Coverage |
Coverage | Entire liver must be covered |
Adult Renal Study(This is not for renal stone evaluation or follow-up) |
Technique Parameters |
Required Series | Non-contrast*** and IV contrast enhanced timed to the corticomedullary phase of renal opacification. In addition, an excretory (delayed) phase is acceptable. |
Reconstructed Slice Width | ≤ 3 mm through the kidneys; the slice width should be the same in all series |
Reconstruction Algorithm | Standard or soft tissue (or appropriate body kernel) |
Oral Contrast | Not required |
CTDIvol | There are no reference values for this examination |
Anatomical Coverage |
Coverage | Must include diaphragm to below both kidneys |
Adult Pancreas Study |
Technique Parameters |
Required Series | Non-contrast*** and IV contrast enhanced |
Reconstructed Slice Width | ≤ 3 mm |
Reconstruction Algorithm | Standard or soft tissue (or appropriate body kernel) |
Oral Contrast | Oral contrast material must be present with barium or neutral (water) contrast agents |
CTDIvol | There are no reference values for this examination |
Anatomical Coverage |
Coverage | Must include entire pancreas |
