As with any test that screens for disease, the risks of full-body CT scans need to be weighed against the benefit of identifying a treatable disease at an early stage. [6] An alternative to a full-body CT scan may be Magnetic resonance imaging (MRI) scans. MRI scans are generally more expensive than CT but do not expose the patient to ionizing ...
The risks of CT scan radiation are especially important in patients undergoing recurrent CT scans within a short time span of one to five years. [157] [158] [159] Some experts note that CT scans are known to be "overused," and "there is distressingly little evidence of better health outcomes associated with the current high rate of scans."
X-ray computed tomography (CT), or Computed Axial Tomography (CAT) scan, is a helical tomography technique (latest generation), which traditionally produces a 2D image of the structures in a thin section of the body. In CT, a beam of X-rays spins around an object being examined and is picked up by sensitive radiation detectors after having ...

[25] In 2011, the National Lung Screening Trial found that CT screening offers benefits over other screenings. [26]

The Ellsworth Howard test (a 10-20 fold increase of urinary cyclic AMP excretion following stimulation with 200 micromoles of parathyroid hormone) may be worth doing also. [citation needed] Serology for toxoplasmosis is also indicated. Brain CT scan is the preferred method of localizing and assessing the extent of cerebral calcifications.
