| Ferda J (2008) Germany | Value of CTA in: 1) Definitive diagnosis of ALI 2) Further management Duration: Jan 2006-Nov 2007 | (n = 106) | Definitive diagnosis in 105 patients Sensitivity 99% | CTA in patients with suspected ALI is a valid diagnostic tool. CTA can provide information relevant for further management. Standard examination protocol should be applied to increase accuracy in reporting. | Availability Accuracy | Nephrotoxicity Radiation exposure False-positive due to vessels calcification. False-positive due to unopacified vessels with the contrast (contrast timing) |

Sensitivity for TASC D lesions in patients with diabetes was lower than in patients without | CTA did not show acceptable results in the assessment of patients with diabetes. Therefore, another method of imaging should be considered for patients who have diabetes. | Non-invasive Availability | Radiation exposure Nephrotoxicity False-positive due to vessels calcification |
