Abstract
It allows detection of important but clinically silent
problems such as lung cancer and suspicious pulmonary
nodules.
CCTA implies a non-negligible probability to
diagnose a previously unknown cancer, which can be
compared with that observed in recent CT trials for lung
cancer screening, ranging from 0.3% to 2.7%, depending
on population characteristics such as age, sex, and smoking
history. The frequency of the incidental finding of
pulmonary nodules in MDCT was reported to range from
5% to 20%.
The detection of additional significant findings with
wide FOV reconstruction cardiac CT may lead to earlier
treatment for serious disease but may also result in
unnecessary, costly, and occasionally harmful evaluations
for findings that prove ultimately to be benign So Larger
studies with large number of patients and longer time of
follow up with histopathological verification of findings are
clearly necessary to determine if the cost-benefit equation
favors a full or more restricted FOV.
The radiation exposure associated with CAC scans
has been significantly reduced where it ranges from 0.9 to
2.4 mSv with prospective multislice CT so we recommend
reconstruction of the raw data of small field of view of
CCTA and also performing the thoracic low dose non
contrast scan during CaS to involve the whole chest.
