Clinical Examples: Scanning with the right dose
CARE Right aims at finding the right dose for every individual patient. What matters is the right balance between image quality and radiation dose. All of CARE Right’s individual areas – Right Dose Technology, Right Dose Levels, and Right Dose Management – come together in the following examples.
Case 1: CT chest angiography pediatrics
Diagnosis: Coarctation of the aorta

Used iterative reconstruction method: SAFIRE
Case 2: CT chest abdomen pelvis angiography
Diagnosis: A re-evaluation CTA using only 20 mL of contrast media confirmed a Stanford B aortic dissection, beginning behind the junction of the left subclavian artery and stretching to just below the diaphragm, with a new partially thrombotic occlusion of the false lumen.

Used iterative reconstruction method: ADMIRE
Case 3: CT abdomen pelvis
Diagnosis: The radiologists found the right balance between applied radiation and image quality. As the habitus of the patient is larger than the reference patient, 5.6 mSv was the right effective dose to achieve this balance. CT images showed a cauliflower-like, broad-based soft tissue mass located on the left-posterior wall of the rectum. It measured 25 x 22 mm and was causing luminal narrowing.
