SURESubtraction CT

SURESubtraction (SCT) Imaging

Enhanced iodine imaging with color mapping and CT angiography subtraction

The pixel perfect iodine extraction in SCT imaging is enabled by industry-leading 3D deformable registration algorithms.

Iodine Mapping SCT
  • Display local iodine concentration
  • Detect/rule out contrast enhancement
  • Detect local perfusion differences
  • Differentiate iodine from calcium
  • Virtual contrast boost
  • Routine with any multi-phase protocol
  • Zero-click workflow

Angiography SCT
  • Automatically remove bone, calcium and stents
  • Visualisation of the true vessel lumen for better quantification
  • Whole body CTA, brain CTA, carotids, aorta, run-off
  • Zero-click workflow

Deformable Registration

Advanced anatomical registration algorithms.

Deformable RegistrationPrior to subtraction, Canon Medical Systems' deformable registration allows pixel matching between the pre-contrast and contrast enhanced data for more accurate digital subtraction and iodine mapping.

Recorded Webinar

SURESubtraction Iodine Mapping in CT Liver

With grey scale images alone it may be difficult to see subtle enhancing lesions. Watch the video to learn from Dr. Teoh at Changi General Hospital, Singapore how Iodine mapping SURESubtraction CT images allow for adequate evaluation of liver lesions, particularly in the setting of post ablation therapy.

"Iodine Mapping may help lesion characterisation, as it allows for confidence detection of enhancement. It may also be useful in evaluating viability of liver lesions which have undergone local ablation therapy."
