LDCT vs. x-ray

LDCT detects lung cancer

better than x-ray among people

at high risk for lung cancer.

However, more so than an x-ray,

a single LDCT test can suggest

there may be cancer when there

isn’t. In other words, LDCT

finds cancer more often but

also has more false alarms.

Figure 4.

LDCT lowers risk

People have a lower chance of

dying from lung cancer when

screened with LDCT.
