DGHS – MoHFW Guidelines on Rational Use of HRCT Imaging

One of the challenges in managing COVID-19 is the identification of a swift, accessible, and reliable diagnostic modality that could serve as an alternative to RT-PCR. This test is used to diagnose a current infection, but its utility as a reference standard is constrained by sampling errors, limited sensitivity (71% to 98%), and dependence on the timing of specimen collection. Chest CT is sensitive but not specific for the diagnosis of COVID-19 in suspected patients. Please share your views on the guidelines on rational use of HRCT Imaging by DGHS-MoHFW.........

CT lungs Good guidence explained Infact it is not the 1st investigation modality to be done to confirm covid19 infection as manifestations may be misleading as they may be delayed as late as 5t06 days which leads delay in specific treatment and so also progress of illness too is not corelating as seen many pts recovered well without complications in view of severity score and some of young pts not judged so severe as per hrct severity score but scumb to disease So also frequent exposure is risky for lungs developing malignancy I feel simple routine xray chest is sufficient to understand the course of illness

Agree Sir

Informative and useful educative update. In case RT-PCR negative HRCT after assessment and evaluation to conclude use must proper and most necessary. Other test like CBC ESR CRP etc to correlate clinical findings. Restricted use of HRCT.

Very practical & useful post on diagnosis of COVID-19. HRCT shud not be irrationally used as routine in place of CXR. Only in limited confirmed and fully decided cases HRCT shud be used but it shud be not abused .As we know repeated invasive radiations may predisposed Cancer and it is costly & non specific also. Presently only RT-PCR test is confirmatory test for diagnosis of Corona but with many errors. Need of some other diagnostic tools without any error & superior to RT-PCR.

Thank you sir
