Many studies throughout world have found CT accounts for just 5% of operations conducted yet 34% yearly exposures in Similarly, other 17% worldwide but 49% total doses Because diagnostic reference levels (DRLs) are one ways optimizing dose procedure, goal this review is provide DRLs adults who undergo chest and abdomen examinations northern India, based on research region comparing with international values see if better optimization protocol being practiced. 18.35mGy index volume (CTDIvol) 765 mGy.cm length product (DLP), according review, while 18.25 mGy 1870.75 CTDI (vol) DLP, respectively. As result, examined had than compared, exception International Commission Radiological Protection 2007 publications. technology desperate need an update. region, methods, including exposure technical parameter selection, should reduce fluctuations.
