1) Subtraction coronary computed tomography angiography (Sub-CCTA) is a novel technique to overcome the difficulties in evaluating coronary artery lumen with high-grade calcification or metallic stents. 2) While the procedure is performed with the dedicated software, acquiring high quality original images without motion is most important. 3) The higher the calcium score, the more difficult to obtain perfect subtracted images. 4) Various factors affect the subtraction of metallic stent including its material, size, and accompanying calcifications.  

1. How to perform Sub-CCTA    (a) Basic principle    (b) Patient preparation    (c) Actual procedures    (d) Tips for successful procedure 2. Factors affecting successfulness of Sub-CCTA   (a) Heart rate and acquisition methods    (b) Image reconstruction methods (full data reconstruction vs. half data reconstruction)    (c) Calcium score    (d) Material and size of stents 3. Diagnostic capability 4. Clinical Cases
