Comparison of image quality in brain MRI with and without MR compatible incubator and predictive value of brain MRI at expected delivery date in preterm babies
Abstract
Objectives
MR compatible incubators (MRcI) offer the examination of preterm and critically ill infants in controlled environment. The aim of the study was to compare objective and subjective image quality as well as diagnostic value of MRI brain examinations with and without using the MRcI. Thus, predictive value of brain MRI at expected delivery date in general was investigated.
Methods
This retrospective study included MRI brain examinations conducted at patients’ corrected age ≤6 months and presence of four standard sequences (PD TSE transversal, T2 TSE transversal, T2 TSE sagittal and T1 SE transversal). Signal-to-Noise Ratio (SNR) and Contrast-to-Noise Ratio (CNR) was calculated. Subjective image quality was estimated using a 5-point Likert scale. Findings of MRI were compared with those of previous transfontanellar ultrasound because of additional diagnostic information. Severe brain abnormality scaled by score of Kidokoro was related to results of Munich Functional Developmental Diagnostics (MFDD) within first year.
Results
One hundred MRI brain examinations (76 with MRcI, 24 without MRcI) were performed in 79 patients. Using the MRcI SNR and CNR were significantly higher in PD- and in T2-weighted sequences (p<0.05). TSE PD transversal demonstrated a higher risk of non-diagnostic quality using MRcI (OR 5.23; 95%-CI 1.86–14.72). MRcI revealed additional diagnostic information (OR 5.69; 95%-CI 1.15–28.24). Severe brain abnormality was associated with walking deficits (r=0.570; p=0.021).
Conclusions
The MRcI increased objective image quality and revealed additional diagnostic information to transfontanellar ultrasound. Nevertheless, prediction of infants' future development remains limited.
