Aeromedical evacuation, a crucial method for casualty transport, significantly enhances survival rates by providing exceptionally rapid transfer and thus gaining valuable treatment time. However, due to the contamination risks during the transport of radioactively contaminated casualties, aeromedical evacuation has not been widely adopted for this specific scenario. This paper reviews the current status of aeromedical evacuation for radioactively contaminated casualties and identifies several challenges. These include incomplete evacuation procedures and regulatory frameworks, difficulties in rapid triage and classification, inadequate evacuation and loading equipment, and the complexity of managing specific injuries during flight. We propose corresponding strategies to address these issues, aiming to provide a reference and guidance for the advancement of aeromedical evacuation for radioactively contaminated casualties.

Objective To compare the role of CTE and CE on the diagnosis of small bowel diseases and evaluate their advantages in patients with different indications.Methods Patients underwent both CTE and CE(interval time <2 weeks)at our institution in recent 3 years were enrolled.The positive detection rates,lesion properties and characteristics of CTE and CE were compared.The diagnostic accuracy of combined method was also analyzed.Results A total of 47 patients were enrolled and the indications included suspected or established Crohn′s disease (28 cases),unexplained abdominal pain (14 cases), obscure gastrointestinal bleeding(3 cases),insufficient small bowel obstruction(1 case)and protein losing enteropathy(1 case).Diagnostic yield of CTE and CE for whole small bowel disorders showed no significant difference(CE 83.0% VS CTE 78.7%,P =0.791).For suspected or established CD,CE had a higher diagnostic accuracy than CTE (78.6% VS 35.7%,P =0.002 ),especially in detecting lesions in the jejunum(CE 50.0% VS CTE 7.1%,P =0.002).The diagnostic accuracy reached 100.0% when two meth-ods were combined.For unexplained abdominal pain,no significant difference was found in the diagnostic ac-curacy of CE and CTE(CTE 42.8% VS CE 50.0%,P =1.000).Diagnostic accuracy of combining CTE and CE was 85.7%.Conclusion CTE and CE are both valuable in detecting small bowel lesions.For pa-tients with suspected or established CD,CE is better than CTE.For patients with unexplained abdominal pain,a combination of CTE and CE may be a better strategy than use CTE or CE alone.
