Heart: Calcium scoring

Specific Anatomic Region Heart

Application Calcium scoring

Author Fishman EK

Reference Source Personal Communication

Scanner Used Siemens Plus4 Volume Zoom

KV / mAs / Time per Rotation (sec) 120 / 149 / .36 sec (partial rotation)

Detector Collimation (mm) 4x 2.5

Slice Thickness (mm) 3

Data Reconstruction Interval (mm) 3

Table Speed (mm per rotation) / Pitch N/A- Sequential study

Oral Contrast N/A

IV Contrast Volume and Type N/A

Injection Rate N/A

Scan Delay (sec) N/A

3D Technique Used N/A

Comment: -The key to this study is obtained data during diastole. This is a gated study which is key to its accuracy. The actual cardiac calcification scoring is a post processing function (See other section on cardiac CT).
