Do you work on all Chest CTs?

ClearRead CT can potentially process all axial CT chest studies that meet the following:

Consistent slice thickness between 0.5 mm and 3.0 mm.
Consistent slice spacing with no gaps.
At least 80 mm of lung present.
Full chest wall visible in the series.
There are additional processing factors, but these are the most basic requirements.

Common study types processed include:

Lung cancer screening.
Chest w/o contrast.
Chest w/ contrast.
Low dose CT.
CTA chest.
Chest/Abdomen/Pelvis exams.

Additional study types can process, but are best considered on a case-by-case basis.

Caveats:

Partial lung exams will have a greater chance of false positives near the break-point of the lung.
Incomplete field of view exams are not recommended for processing.
