Aim:
This study aimed to evaluate the efficacy of thin-section CT of the mediastinum in the assessment of thoracic lymph nodes in comparison with conventional CT.
Materials And Methods:
A total of 193 CT examinations from 193 patients with suspected pulmonary disease were reconstructed into thin-section CT and conventional CT. The appearances of the lymph nodes were assessed and compared between thin-section CT and conventional CT.
Results:
Intranodal fat was more often detected on thin-section CT than on conventional CT (P<.001). There were no statistically significant differences in the frequencies of inhomogeneous enhancement and bulging margin of the hilar lymph node.
Conclusion:
Thin-section CT can improve clinical N-staging of lung cancer due to classification of enlarged mediastinal lymph nodes as benign based on identification of intranodal fat.

01:23Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

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...
