概括
诊断罕见的主性恶性大动脉瘤 (PMTA) 是一个挑战. F-18氧葡萄糖-正子发射断层扫描/计算机断层扫描 (FDG-PET/CT) 有效地将PMTA与动脉血性病变区分开来,有助于诊断和管理.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
411
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Aneurysm II: Clinical Manifestations and Diagnostic Studies
303
Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
