Sequences of SS_TSE and Modified Abdominal T2WI Magnetic Resonance Imaging in the Diagnosis of Neonatal Pneumonia
Background In the diagnosis of neonatal pneumonia, the possibility of iatrogenic injury caused by magnetic resonance imaging (MRI) may be lower than that by widely used X-ray and even computed tomography scan. However, there are few studies on the application of MRI in the diagnosis of neonatal pneumonia. Objective To explore the feasibility of using MRI for the diagnosis of neonatal pneumonia in primary care based analyzing the application of SS_TSE and modified abdominal T2WI sequences at 1.5 Tesla for the diagnosis of this illness. Methods Nineteen neonates diagnosed with pneumonia by MRI were selected from Wuchuan People's Hospital from January to November 2020. Six parameters under SS_TSE and modified abdominal T2WI sequences including subjective MR score, signal intensity of the lesion (SI lesion) , lung signal intensity (SI lung) , lung noise (SD lung) , calculated image signal-to-noise ratio (SNR) and lesion signal intensity ratio (SIR) were statistically analyzed. Results The values of these six parameters of SS_TSE sequence were 2.2 (2.0, 2.8) , (505.0±102.5) , (243.5±32.0) , (21.8±6.7) , (12.0±3.1) , and 2.1 (2.0, 2.2) , respectively. And The values of subjective score, SI lesion, SI lung, SD lung, SNR and SIR of T2WI sequence were 2.7 (2.0, 3.3) , (293.1±129.6) , (99.7±40.3) , (19.0±7.6) , (5.6±2.3) , and 3.1 (2.6, 3.2) , respectively. Based on the combination of SS_TSE and T2WI images, the diagnoses for all cases were made. Conclusion The brightness of the lesions in SS_TSE sequence is higher, with better objective definition of the images. T2WI sequence has higher subjective definition, and the signal of the lesions was markedly different from the background, which is helpful to observe the border of the lesions. SS_TSE and T2WI sequences are complementary in the diagnosis of neonatal pneumonia. In a word, it is feasible to apply MRI for the diagnosis of neonatal pneumonia at 1.5 Tesla to reduce the possibility of iatrogenic injury..
