'Reconstructed radiographs' from MDCT volume data: Why to still ask for a conventional radiograph, after CT is done?

'MDCT-reconstructed radiographs' is a radiograph generated from the MDCT volume data. It is important to be aware of the ability of MDCT to generate 'reconstructed radiographs' with use of mean-intensity projection or average intensity projection (mean-IP or average-IP) and its potential clinical applications. Whenever there is a need for radiograph after CT is already done, clinicians may ask for 'MDCT reconstructed radiographs' rather than conventional radiograph. This will also ensure that the volume acquisition during MDCT study which has already subjected the patient to radiation dose is optimally post-processed to extract the maximum information and the need for any further radiographic exposure is minimized. This clinical practice is likely to minimize the need for a conventional radiograph in a wide range of clinical conditions, after CT is done; as illustrated in this pictorial communication.
