CT chest scanning is the best and foremost modality used in radiology to access the lungs and the structures in between the lungs. In these images,
scans provide excellent information about lung nodules as to their characteristics and composition. It can easily be determined if they are calcified or non calcified, rounded with distinct boarders or have spiked, pointed borders or if they’re partly composed of calcium. It is superior at visualizing lung masses and tumors and provides characteristics about whether a mass or tumor is composed of differing densities.
It can also reveal If there is any possible blood flow around or in a lung mass or tumor. Chest tomography is also superior at visualizing a collapsed lung.
Shapes and sizes can be seen and measurements can be made of lung tumors, masses or nodules of lesions up to .5mm. It is by far the most advanced way of evaluating the chest and lungs than all other imaging modalities in radiology.
