General Hints
• Topogram: AP, 512/1024, LAT 256
• Patient positioning:
Patient lying in supine position, arms positioned
comfortably above the head in the head-arm rest,
lower legs supported.
• Patient respiratory instructions: inspiration.
• Oral administration of contrast medium:
The use of water will not obscure the blood vessels
thus allowing CTA processing to be performed easily
afterwards.
• Be careful when examining pheochromocytoma
patients. Administration of an IV CM injection in
such cases may trigger a hypertensive crisis!
• To further optimize MPR image quality we recom-
mend that you reduce one or more of the following:
collimation, reconstruction increment and slice
width for image reconstruction.
