Inclusion criteria
Inclusion criteria: 1.Aged 18 to 75 years, ensuring participants are medically stable and better able to tolerate study procedures, while encompassing the common age range of adult patients with limited arm elevation. 2.Requiring chest/abdominal CT scanning for clinical diagnostic needs and assessed as unable to assume the standard arm-raised position, confirming the study targets patients facing actual scanning difficulties. 3.Cognitively intact with the capacity to comprehend study information and provide informed consent; OR, for patients lacking decision-making capacity, a legally authorized representative capable of fully understanding the study and providing consent, ensuring the protection of patients' rights to information and autonomous choice.
Exclusion criteria
Exclusion criteria: 1.Presence of severe mental illness or cognitive impairment preventing cooperation with study procedures (e.g., inability to understand study requirements or maintain required positioning), to prevent compromise of data accuracy and study conduct due to patient-related factors. 2.Presence of non-removable metallic implants (e.g., cardiac pacemakers, large metal fragments), as these may cause significant metal artifacts interfering with CT image interpretation, to avoid confounding study results. 3.Pregnancy, due to the potential risk of radiation exposure to the fetus, ensuring the health and safety of both the pregnant individual and the fetus. 4.History of severe allergy to iodinated contrast media, and potential requirement for contrast-enhanced scanning in this study, to prevent life-threatening anaphylactic reactions, ensuring patient safety and study stability.
