Together with WHO Stop TB diagnostics team members CheckTB! will propose criteria (key performance indicators) that can be applied on pilot roll outs of digital radiology, for e.g. large-scale prevalence studies, in low and medium resource areas. These field data can serve to perform comparative analyses and to update WHO recommendations on the use of chest X-rays.

At the same time this field experience is to provide additional supporting evidence for effectively addressing quality concerns on the wider use of chest X-ray effectively.

Quality Assurance of CXR; by Dr I Onozaki 

"Limitations on the wider use of Chest X-rays, such as non-availability at peripheral health facilities and the difficulty of interpreting results, even by trained physicians, need to be addressed."

"Research is needed to identify innovative ways to enhance the ability of clinicians, including non-physicians, to interpret Chest X-rays accurately."

"Chest  X-ray plays an important role in the diagnostics of TB and non-TB chest diseases common among people living with HIV."

"Chest X-rays play a significant role in shortening delays in diagnosis."

"Avoiding films by using digital Chest X-ray is an important advantage; Digital technology has a potential to solve most CXR problems"
