“…While processing this article for publication, another study was published about the accuracy of MRI in CLM. 4 The results of both experiences agree in the underlying usefulness of MRI for postnatal diagnosis and management of CLM, allowing an accurate and early diagnosis and avoiding ionizing radiation exposure and intravenous contrast administration. The main differences between our work and the mentioned article are the timing and modality of postnatal MRI.…”

“…While some studies have investigated the use of prenatal US compared with prenatal MRI and postnatal CT, 21 only a single study has been published about the comparison of postnatal MRI and postnatal CT. 4 As far as we know, this study is the first to compare the results of postnatal MRI and preoperative CT scan, to surgical pathology of thoracoscopically resected CLM in infancy, and to investigate the best preoperative assessment both for patients and for surgeons.…”

“…Concordance between MRI and CT scan was evaluated comparing the dimensions of the malformations and other noncontinuous variables such as the localization of the lesion and the presence or absence of: arterial vessel (AV) afferent to the lesion, venous vessel (VV) efferent from the lesion, overinflated areas (OAs), air cysts (ACs), liquid cysts (LCs), bronchocele (BR), bronchial atresia (BA), pneumothorax (PNX), pleural effusion (PE), dysventilation areas (DAs), pulmonary nodules (PNs), and lymph nodes (LNs) >1 cm. 4 Images were independently and blindly analyzed by two pediatric radiologists experienced in the thorax. Analysis from both of these radiologists was then compared.…”

Introduction Consensus on the best postnatal radiological evaluation of congenital lung malformations (CLMs) is still lacking. In recent years, the interest on magnetic resonance imaging (MRI) has grown, but its role is still unknown. Aim The aim of the study was to identify the best preoperative diagnostic assessment for CLM. Materials and Methods All patients with a prenatal suspicion of CLM between January 2014 and February 2018 were studied. Asymptomatic newborns underwent MRI, during spontaneous sleep without contrast. Patients with a positive MRI were scheduled for computed tomography (CT) within the fourth month of life. Thoracoscopic resection was performed in cases with a pathological CT. MRI, CT, and surgical findings were compared based on dimension, localization, and features of the CLM using the Cohen's kappa test (K). Results A total of 20 patients were included (10 males). No difference was found in the diameter and site of the lesions always localized in the same side (K = 1) and in the same pulmonary lobe (K = 1). Infants who underwent thoracoscopic resection included: three congenital pulmonary airway malformations (CPAMs), five extralobar and eight intralobar sequestrations (bronchopulmonary sequestrations [BPSs]), three bronchogenic cysts, and one congenital emphysema. The concordance between MRI and CT and between radiological investigations and pathology was satisfactory for the greatest part of the studied variables. MRI showed sensitivity of 100%, specificity of 82%, positive predictive value of 50% and negative predictive value of 100% for CPAM and 77, 100, 100, and 80% for BPS, respectively. Conclusion MRI proved to be a reliable diagnostic investigation for CLM with high sensitivity and specificity. Early MRI in spontaneous sleep without contrast and preoperative contrast CT scan is a valuable preoperatory assessment.

“…The majority of bronchopulmonary malformations are first identified on prenatal US screening, most often in the second trimester [5][6][7][8][9]. Many undergo further evaluation in utero with one or more fetal MRI examinations, which have been shown to be accurate for assessing location, size, extent, mass effect and internal features, and for assisting in management decisions such as method, time and location of delivery or occasionally in utero intervention [7,[10][11][12].…”

Congenital lung malformations are most often identified on prenatal US screening. Fetal MRI is often performed to further evaluate these lesions. Although some of these lesions might cause prenatal or early postnatal symptoms that require urgent management, the majority are asymptomatic at birth and might be subtle or invisible on chest radiographs. Postnatal imaging is frequently deferred until 3–6 months of age, when surgery or long-term conservative management is contemplated. High-quality imaging and interpretation is needed to assist with appropriate decision-making. Contrast-enhanced chest CT, typically with angiographic technique, has been the usual postnatal imaging choice. In this review, the author discusses and illustrates the indications and use of postnatal MR imaging for bronchopulmonary malformations as well as some differential diagnoses and the advantages and disadvantages of MR versus CT.

“…This means that the boundaries have become blurred: "Inbetween pathologies" could be called diseases that, depending on the referrer's familiarity and the radiologist's expertise, can be diagnosed at MRI too. These include lung cysts and congenital pulmonary airway malformation (CPAM) Types 1 and 2 [10].…”

Lung MRI makes it possible to replace up to 90% of CT examinations with radiation-free magnetic resonance diagnostics of the lungs without suffering any diagnostic loss. The individual radiation exposure can thus be relevantly reduced. This applies in particular to children who repeatedly require sectional imaging of the lung, e.g., in tumor surveillance or in chronic lung diseases such as cystic fibrosis. In this paper we discuss various factors that favor the establishment of lung MRI in the clinical setting. Among the many sequences proposed for lung imaging, respiration-triggered T2-W turbo spin-echo (TSE) sequences have been established as a good standard for children. Additional sequences are mostly dispensable. The most important pulmonary findings are demonstrated here in the form of a detailed pictorial essay. T1-weighted gradient echo sequences with ultrashort echo time are a new option. These sequences anticipate signal loss in the lung and deliver CT-like images with high spatial resolution. When using self-gated T1-W ultrashort echo time 3-D sequences that acquire iso-voxel geometry in the submillimeter range, secondary reconstructions are possible.
