Objective: There has been increased interest in magnetic resonance imaging (MRI) of the lung parenchyma in recent years. We aimed to evaluate the pulmonary MRI findings of patients in the light of literature data in this study.
Material
and
Methods: Fifteen patients who underwent pulmonary MR imaging between April 2017 and January 2018 were included in our study. Demographic information, clinical preliminary diagnosis and imaging findings of the patients were retrospectively evaluated. Axial and coronal T2-weighted (T2W) and axial fat-saturated T2W images were obtained from all patients.
Results:The mean age of the patients (7 girls, 8 boys) was 7.8 years (5 months -18 years). Lung MRI was used for the diagnosis of neutropenia-related infection during follow-up for hematologic-oncological diseases (n=6), lung hydatid cyst and follow-up of complications (n=2), metastasis scan (n=2), empyema diagnosis and/or follow-up of treatment (n=4), and lung mass-infection distinction (n=1). Twelve of the children were also imaged with computed tomography before lung MRI. In the follow-up MR imaging of patients with neutropenia and lung infection; the nodules and consolidated areas disappeared and became smaller in three patients, the number of nodules increased in one patient, and the number of nodules remained stable but became cavitated in one patient. In the patient with Fanconi aplastic anemia, a diagnosis of fungal infection was made by showing the reverse target sign on MRI. Patients with lung hydatid cyst and tuberculosis were differentiated from a lung mass easily. In the follow-up of three patients with necrotizing pneumonia
and empyema, the empyema/parenchymal infection findings were shown to be improved and one patient’s empyema associated with parenchymal consolidation was diagnosed with MRI.
Conclusion: MRI has promising results in imaging parenchymal diseases of the lung. The most important advantage of MRI is the lack of radiation. MRI is useful in the diagnosis and follow-up of lung infections and complications in children, especially those who are immunocompromised or sensitive to radiation.
Amaç: Son yıllarda akciğer parankiminin manyetik rezonans görüntülemesine (MRG) ilgi artmıştır. Çalışmada akciğer MRG görüntülemesi yapılmış hasta bulgularının literatür verileri eşliğinde değerlendirilmesi amaçlanmıştır.
Gereç
ve
Yöntemler: Çalışmaya hastanemizde Nisan 2017 – Ocak 2018 tarihleri arasında akciğer MRG tetkiki yapılmış 15 hasta dahil edilmiştir. Hastaların demografik bilgileri, klinik ön tanıları ve görüntüleme bulguları geriye dönük olarak değerlendirilmiştir. Tüm hastaların aksiyel ve koronal T2 ağırlıklı (T2A), aksiyel yağ baskılı T2A görüntüleri elde olunmuştur.
Bulgular: Hastaların (7 kız, 8 erkek) yaş ortalaması 7.8 (5 ay-18 yaş) yaştı. Akciğer MRG, hematolojik-onkolojik hastalıkları nedeniyle tedavileri sırasında gelişen nötropeni ilişkili akciğer enfeksiyonunun tanısında ve takibinde (6 hasta), akciğer kist hidatiğinin tanısı ve komplikasyonlarının takibinde (2 hasta), metastaz taramasında (2 hasta), ampiyem tanısında ve/veya tedavisi sonrası takibinde (4 hasta), akciğer kitlesi-enfeksiyon ayrımında (1 hasta) kullanılmıştır. Hastaların 12’si MRG öncesi bilgisayarlı tomografi ile de tetkik edilmiştir. Nötropenisi ve akciğer enfeksiyonu olan hastaların üçünde nodüllerin ve/veya konsolide alanların kaybolduğu ve küçüldüğü, bir hastada nodüllerin sayısının arttığı, bir hastada da nodüllerin sayısının değişmediği ve bir kısmının kaviteleştiği izlenmiştir. Fankoni aplastik anemisi olan hastada MRG’de ters hedef işaretinin gösterilmesi ile fungal enfeksiyon tanısı konmuştur. Akciğer kist hidatiği ve tüberkülozu olan hastalarda kitle-enfeksiyon ayrımı kolaylıkla yapılabilmiştir. Nekrotizan pnömoni ve ampiyemi olan üç hastanın kontrolünde ampiyem/parankimal enfeksiyon bulgularının gerilediği gösterilirken bir hastanın parankimal konsolidasyonuna eşlik eden ampiyem tanısı MRG ile konmuştur.
Sonuç:
MRG’nin akciğerin parankimal hastalıklarının görüntülemesinde ümit verici sonuçları vardır. MRG’nin radyasyon içermemesi en önemli avantajıdır. Başta immünkompromize ve radyasyon duyarlılığı olan hastalar olmak üzere çocuklarda akciğer enfeksiyonunun ve komplikasyonlarının tanısında ve takibinde MRG faydalıdır.

The publication language of Turkish Journal of Pediatric Disease is English.
Manuscripts submitted to the Turkish Journal of Pediatric Disease will go through a double-blind peer-review process. Each submission will be reviewed by at least two external, independent peer reviewers who are experts in the field, in order to ensure an unbiased evaluation process. The editorial board will invite an external and independent editor to manage the evaluation processes of manuscripts submitted by editors or by the editorial board members of the journal. The Editor in Chief is the final authority in the decision-making process for all submissions. Articles accepted for publication in the Turkish Journal of Pediatrics are put in the order of publication, with at least 10 original articles in each issue, taking into account the acceptance dates. If the articles sent to the reviewers for evaluation are assessed as a senior for publication by the reviewers, the section editor and the editor considering all aspects (originality, high scientific quality and citation potential), it receives publication priority in addition to the articles assigned for the next issue.
The aim of the Turkish Journal of Pediatrics is to publish high-quality original research articles that will contribute to the international literature in the field of general pediatric health and diseases and its sub-branches. It also publishes editorial opinions, letters to the editor, reviews, case reports, book reviews, comments on previously published articles, meeting and conference proceedings, announcements, and biography. In addition to the field of child health and diseases, the journal also includes articles prepared in fields such as surgery, dentistry, public health, nutrition and dietetics, social services, human genetics, basic sciences, psychology, psychiatry, educational sciences, sociology and nursing, provided that they are related to this field. can be published.
