Two patients were excluded from analyses, one for technical difficulties and one for drug abuse on the day of scanning.
Scan rules, the way of scanning.
The 3D scanning system using a 3D scanner, which was employed in our previous study [16], is not utilised in the clinical trial due to the difficulty of the scanning procedure.
The majority of fMRI studies with autistic participants involve both adolescents and adults, by reason of the difficulty in scanning younger patients and in obtaining suitable age-matched controls.
The difficulty of interpreting bone scan changes even for experienced readers is the incentive to develop an objective method in order to minimise disagreement among observers.
Another difficulty of a fast scan is that there is a greater risk of asymmetric enhancement in patients with severe unilateral vascular disease.
Moreover, difficulties to scan populations of fertile age females may be related to the broad and frequent overlap of the symptoms for acute abdominal conditions [16 20].
The volumes of all organs at risk (OAR) were contoured from the CT scans due to the inherent difficulty of detecting edges on PET scans.
To increase the generalizability of our study results, we included all saved clips regardless of scan difficulty or quality.
