Results

Among the 78 responding sites from 34 countries and 5 geographical regions,

Fig 2: Survey done in 5 different regions - Latin America, Central/Eastern Europe, Asia, Middle East, and Northern Africa
Fig 3: List of participating countries
Fig 4: Types of hospital practice where CT examinations are performed. Majority (44%) are CT examination within a large hospital (>500 beds)
  32% (25/78) sites reported frequently incomplete clinical indications for CT examinations and 26.9% (21/78) reported frequent errors in clinical indications.
Fig 5: Distribution of frequencies of getting information about initial or follow-up CT examination. 42% radiologists responded "commonly" for getting information on the status of CT examination
Fig 6: Modes of requisition for the CT examinations by the physicians. Majority (50%) are paper based requests
Fig 7: Personnel responsible for deciding body part and CT protocol selection for the given clinical indication. 38% respondents answered "radiologists"
Fig 8: Distribution of MRI machines in the institutions with majority (42%) of sites having one machine
Fig 9: Waiting period for scheduling routine or non-urgent CT examination is less than one day for majority (36%) of sites
Fig 10: Distributions of different types of CT scanners at the institution with majority of sites having 32-64 slice scanner
Fig 11: Distribution of number of CT examinations performed each year: 28% of sites reported having more than 20000 examinations per year
 
Fig 12: Distribution frequency of medical physicists at the institution: Majority of sites (61.5%) had medical physicists at their institution
Most radiologists (84.6%, 66/72) stated they “rarely” changed the ordered imaging based on the provided indications. About 58.9% (46/78) of radiologists replied that the referral physicians “rarely” consulted them for selecting the best imaging procedure, and 57.6% (45/78) mentioned that physicians “rarely” specified the CT protocols or a number of phases. Only 41% (32/78) of technologists “commonly” change scan protocol based on clinical indication.
Fig 13: Number of scan phases for each of the following CT abdomen protocols for different clinical indication
Fig 14: Number of scan phases for each of the following CT chest protocols for different clinical indication
Fig 15: 29% of technologists responded they rarely changed scan acquisition factors based on breath holding
Fig 16: Number distributions of CT protocol for different CT examinations based on body region with majority sites using 3 to 5 protocols
Fig 17: Scan protocol adjustment by technologists
  Several sites (64.1%, 50/78) reported use of single chest and abdomen CT protocol regardless of patient size.
Fig 18: Distribution frequency of CT examination performed for children with two or more phases: majority respondents selected "1-25%"
About 48.7% (38/78) sites used iterative reconstruction for all CT exams, but most sites adjust kV, mA, scan length and scan phases per body size and clinical indications (65.3%, 51/78).
Fig 19: 63% of technologists used different scan acquisition factors for different clinical indication for the same body region
Fig 20: Majority of technologists (33%) did period review frequency of CT protocols once a year
