ABSTRACT
This chapter describes the evaluation process as it is performed in Rotterdam as well as alternative approaches. There is more than one way to assess a computed tomography (CT) coronary angiogram. Screening the image quality of the data set allows the gross cardiac and coronary anatomy to be interpreted. Assessment of the coronary lumen, to detect or exclude significant coronary stenosis, is often the primary indication for a coronary CT scan. Particularly in cases with little or no coronary calcification or apparent plaque, stenotic disease in the larger branches is virtually excluded in a very short time. The left main coronary artery (LMCA) can be assessed in the vast majority of cases, as it has the largest diameter of all coronary branches. The left anterior descending coronary artery can be found in the anterior interventricular groove of the heart, usually continuing in the same direction as the distal LMCA.
