Read the full statement (138 words)

From user specified sets of CT cardiac images, Calcium Scoring can be used to: -

Allow the user to interactively indicate regions of detected calcification

To allow the user to allocate each detected region to one of several coronary arteries

To estimate algorithmically a score for the amount of detected calcification in each allocated artery

To prepare reports including caicium score data, imagery, ECG traces, Comparison of score to cited literature and additional relevant information

The calcium-scoring package is a diagnostic tool that can be used to evaluate the caicified plaques in the caronary arteries, which is a risk factor for coronary artery disease. Calcium scoring may be used to monitor the progression or regression overtime of the amount or volume of calcium in the coranary arteries, which may be related to the pregnosis of a cardiac attack.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
