Abstract
Unlike previous generations of MDCT scanners, the temporal resolution in DSCT is independent of the patient’s heart rate because data from only a single cardiac cycle contribute to the reconstruction of one image. In most recent DSCT scanners, the temporal resolution has been reduced to 66 ms at 0.25-s rotation time by combining data from the two detectors. Combining data from the two measurement systems provides not only high temporal resolution but also very high scan speeds. These improvements have a tremendous impact on cardiac CT applications in small animals. Motion artifacts occur frequently in non-ECG-gated cardiac imaging with high heart and respiratory rates. In veterinary patients, slight motion may be acceptable for the visualization of larger lesions, such as heart-base masses, but small anatomical structures such as the coronary arteries may not be visible and small lesions may be missed or misinterpreted. DSCT dramatically improves the feasibility of cardiac CT in veterinary patients and has the potential to significantly impact the diagnosis and management of cardiovascular diseases in the near future.
