“…We have already described a case in which the association of abdominal cyst with the biliary ducts was excluded. 3 In another baby, this relationship was found on MRI and MR-cholangiography, and a common bile duct cyst was diagnosed implying referral of the newborn to another tertiary reference center that deals with biliary malformations. There is also a case of gallbladder duplication in our material.…”

“…Since the time when we published our first experience with magnetic resonance imaging (MRI) in neonates with the use of a specialist incubator compatible with an MRI system (INC), 1 5 more papers including the keywords "MRI", "neonates" and "MR compatible incubator" have been added to PubMed and 2 of these are ours. 2,3 Although the first publication concerning INC dates back to 2003, 4 there are only 22 articles devoted to this subject in PubMed now (including 3 of ours) and almost all of them are focused on safety issues and brain imaging. [4][5][6][7] Our INC, equipped with a head coil and a body coil, allows more than neuroimaging, and we have noticed the growing role of neonatal body MRI in everyday clinical practice.…”

Background. The use of a specialized MR-compatible incubator (INC) is very poorly described in the literature and only with regard to brain imaging. Objectives. To present our own experience with brain and body magnetic resonance imaging (MRI) in the INC in a large cohort of neonates. Material and methods. A total of 555 examinations were performed in 530 newborns with the use of a 1.5T system and Nomag IC 1.5 incubator, equipped with head and body coils. Results. More than half of neonates (54%) were prematurely born at 22 + 6-36 + 6 gestational weeks. They were examined from the first to 153 days of life (median: 18.5, mean: 37.7) with body weights 600-5000 g (mean: 3051 g), 23% of less than 2500 g. The proportion of brain MRIs to other body regions was 533:85 = 86%:14%. In 36.6% of cases, MRI showed more abnormalities than ultrasound (USG), in a further 21.8%, MRI diagnosis was completely different, in 4.7%, a pathology described on a USG was ruled out on MRI. The superiority of MRI over USG was 63. 1%. Conclusions. MR-compatible incubator significantly increased the availability of MRI to newborns, especially to premature and unstable newborns. The integration of body coils into the INC increased the spectrum of examinations and made possible the scanning not only of the brain but also the body. Dedicated neonatal coils improved image quality and allowed more accurate diagnosis than the previously used adult coils. Immobilization of the babies in the INC by means of Velcro belts and head fixation inserts is better than in adult coils. The closed space of the INC isolates newborns to a greater extent from the negative influence of noise in the MR environment.

To investigate differences in the functional connectivity (FC) of the primary visual cortex between patients with corneal ulcer (CU) and healthy controls (HCs) using restingstate functional magnetic resonance imaging. Patients and Methods: A total of 30 patients with CU and 30 HCs were closely matched in terms of sex, age, and level of education. Two-sample t-test, receiver operating characteristic curve, and Pearson's correlation coefficient analyses were used to determine the differences in FC between the two groups, the mean FC value of patients with CU and HCs, and the correlation between FC signal values and clinical manifestations in different brain regions of patients. Results: The CU group showed significantly elevated FC in the left and right middle frontal gyri and lower FC with the right cuneus compared with the HC group. In addition, the FC of the right cingulate and left superior frontal gyri also increased in the CU group. The receiver operating characteristic curve revealed high diagnostic value in those brain regions. Conclusion: CU involves aberrant FC of the primary visual cortex in different brain areas, including visual-related and cognitive-related regions. This finding may unveil the underlying neural mechanisms of impaired visual function in CU.

“…Functional magnetic resonance imaging (fMRI) is a method for detecting brain changes (7,8), and may be utilized to enhance the current knowledge on ophthalmological diseases. fMRI is a neuroimaging research technique for exploring the brain and central nervous system; it may be used for monitoring the spontaneous neuronal activity of the human brain and provide novel explanations for the pathophysiology of certain conditions (9).…”

The aim of the present study was to investigate the altered spontaneous brain activity in patients with corneal ulcer (CU) through the amplitude of low-frequency fluctuation (ALFF) technique and the association with their visual performance. A total of 40 patients with CU and 40 healthy controls (HCs) matched for sex, age and educational level were enrolled. Resting-state functional magnetic resonance imaging (rs-fMRI) was performed to examine the probands. Spontaneous cerebral activity variations were investigated using the ALFF technique. The average ALFF values of the CU patients and the HCs were classified by utilizing receiver operating characteristic (ROC) curves. Contrary to HCs, the CU patients had significantly lower ALFF values in the left cerebellar anterior lobe, right middle frontal gyrus and left middle frontal gyrus, but higher ALFF values in the right cerebellar inferior lobe, left cerebellar inferior lobe, left inferior temporal gyrus, right fusiform gyrus, left superior frontal gyrus, right angular gyrus and bilateral superior frontal gyrus. ROC curve analysis of each brain region indicated that the accuracy of ALFF value specificity between the CU and HCs of the area under the curve was perfect. In conclusion, abnormal spontaneous activities were detected in numerous brain regions of CU patients, which may provide useful information for understanding the dysfunction of CU. These activity changes in brain regions may be used as effective clinical indicators for CU.
