Prenatal diagnosis of a coronary-to-pulmonary artery fistula in a fetus with pulmonary atresia and ventricular septal defect.

BMJ Case Rep 2022 Jun 22;15(6). Epub 2022 Jun 22.

Department of Pediatrics, School of Medicine Graduate School of Medicine, Osaka University, Suita, Osaka, Japan.

Pulmonary atresia and ventricular septal defect (PA/VSD) demonstrate a wide variety of pulmonary and coronary artery abnormalities; additionally, coronary-to-pulmonary artery fistula (CPAF) is a rare manifestation of PA/VSD and is seldom detected during pregnancy. In this report, we present a case of prenatal diagnosis of CPAF in PA/VSD and impactful images in a neonate, which were obtained using fetal echocardiography and postnatal electrocardiography-gated 320-row CT. Prenatal diagnosis of CPAF can facilitate the provision of better therapeutic strategies after birth. Read More

Imaging Approach to Pulmonary Infections in the Immunocompromised Patient.

Indian J Radiol Imaging 2022 Mar 27;32(1):81-112. Epub 2022 May 27.

Department of Microbiology, Vardhman Mahavir Medical College and Safdarjung Hospital, New Delhi, India.

Pulmonary infections are the major cause of morbidity and mortality in immunocompromised patients and almost one-third of intensive care unit patients with pulmonary infections belong to the immunocompromised category. Multiple organisms may simultaneously infect an immunocompromised patient and the overwhelming burden of mixed infections further predisposes critically ill patients to acute hypoxemic respiratory failure. Notwithstanding that lung ultrasound is coming into vogue, the primary imaging investigation is a chest radiograph, followed by thoracic CT scan. Read More

Evaluation of injuries caused by coronavirus disease 2019 using multi-nuclei magnetic resonance imaging.

Magn Reson Lett 2021 Aug 8;1(1):2-10. Epub 2021 Aug 8.

Key Laboratory of Magnetic Resonance in Biological Systems, State Key Laboratory of Magnetic Resonance and Atomic and Molecular Physics, National Center for Magnetic Resonance in Wuhan, Wuhan Institute of Physics and Mathematics, Innovation Academy for Precision Measurement Science and Technology, Chinese Academy of Sciences-Wuhan National Laboratory for Optoelectronics, Wuhan, 430071, China.

The ongoing pandemic of coronavirus disease 2019 (COVID-19) has been a great burden for the healthcare system in many countries because of its high transmissibility, severity, and fatality. Chest radiography and computed tomography (CT) play a vital role in the diagnosis, detection of complications, and prognostication of COVID-19. Additionally, magnetic resonance imaging (MRI), especially multi-nuclei MRI, is another important imaging technique for disease diagnosis because of its good soft tissue contrast and the ability to conduct structural and functional imaging, which has also been used to evaluate COVID-19-related organ injuries in previous studies.

Congenital diaphragmatic hernia.

Nat Rev Dis Primers 2022 06 1;8(1):37. Epub 2022 Jun 1.

Department of Surgery, Division of Paediatric Surgery, Paediatrics & Child Health, Physiology & Pathophysiology, University of Manitoba, Winnipeg, Manitoba, Canada.

Congenital diaphragmatic hernia (CDH) is a rare birth defect characterized by incomplete closure of the diaphragm and herniation of fetal abdominal organs into the chest that results in pulmonary hypoplasia, postnatal pulmonary hypertension owing to vascular remodelling and cardiac dysfunction. The high mortality and morbidity rates associated with CDH are directly related to the severity of cardiopulmonary pathophysiology. Although the aetiology remains unknown, CDH has a polygenic origin in approximately one-third of cases. Read More
