In this situation, the cost of a CT scan will go toward your Part A deductible. In 2024, the Part A deductible is $1,632 for each benefit period , and in 2025, it is $1,676.
In 1996, results were published of a study of 1369 subjects screened in Japan that revealed that 73% of lung cancers that were missed by chest x-ray were detectable by CT scan. [19] Among the earliest United States-based clinical trials was the Early Lung Cancer Action Project (ELCAP), which published its results in 1999. [ 20 ]
The United States Preventive Services Task Force (USPSTF) is "an independent panel of experts in primary care and prevention that systematically reviews the evidence of effectiveness and develops recommendations for clinical preventive services". [1]
A full-body scan is a scan of the patient's entire body as part of the diagnosis or treatment of illnesses. If computed tomography ( CAT ) scan technology is used, it is known as a full-body CT scan , though many medical imaging technologies can perform full-body scans.

A dual detector head gamma camera combined with a CT scanner, which provides localization of functional SPECT data, is termed a SPECT-CT camera, and has shown utility in advancing the field of molecular imaging. In most other medical imaging modalities, energy is passed through the body and the reaction or result is read by detectors.
Douglas Boyd, PhD and Harry Genant, MD used a CT head scanner to do some of the seminal work on QCT. [3] At the same time, CT imaging technology progressed rapidly and Genant and Boyd worked with one of EMI's first whole body CT systems in the late 1970s and early 1980s to apply the quantitative CT method to the spine, coining the term "QCT."
Contrast agents are sometimes used in CT scans of the chest to accentuate or enhance the differences in radiopacity between vascularized and less vascularized structures, but a standard chest CT scan is usually non-contrasted (i.e. "plain") and relies on different algorithms to produce various series of digitalized images known as view or "window".
