WHO STOP TB Print

Together with WHO Stop TB diagnostics team members CheckTB! will propose case detection projects for operational research on effectiveness of digital radiology (e.g. large-scale prevalence studies). These field data can serve to perform comparative analyses and to update WHO guidelines and recommendations on the use of chest X-rays also in combination with molecular tests.

At the 41st UNION World Conference in Berlin the high sensitivity of Chest X/ray was illustrated by findings in the TB prevalence surveys in Viet Nam and Cambodia. The fact that screening on symptoms only can result in missing more than 40% of TB cases, now makes Chest X-ray with high sensitivity levels a mandatory part of any TB prevalence survey, as mentioned in the WHO Workshop on Prevalence Surveys in Berlin.

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"
