Normal Anterior Junction Line Thickness on Radiography
The normal anterior junction line on PA chest radiography measures less than 1 mm; thickening or displacement suggests mediastinal pathology.

A
Normal Aortic Nipple Diameter on Chest Radiography
Normal aortic nipple maximal diameter is less than 4.5 mm on PA chest radiography; larger measurements may indicate venous or vascular pathology.
B
Normal Bronchus Intermedius Posterior Wall Thickness on Radiography
Normal bronchus intermedius posterior wall thickness on lateral chest radiography is less than 3 mm — a key landmark for detecting mediastinal and pulmonary pathology.
C
Normal Carina Angle Size on Chest Radiography
The normal carina angle on posteroanterior chest radiography measures 40–80°, with widening suggesting left atrial or subcarinal pathology.
P
Normal Posterior Junction Line Thickness on Radiography
The normal posterior junction line measures less than 1 mm on PA chest radiography; understanding this landmark helps detect mediastinal pathology early.
Normal Posterior Tracheal Wall Thickness on Radiography
Normal posterior tracheal wall thickness on lateral chest radiography measures less than 2.5 mm — a key landmark for detecting retrotracheal pathology.
R
Normal Right Paratracheal Stripe Width on Chest X-Ray
The normal right paratracheal stripe measures less than 4 mm on anteroposterior chest radiography; widening suggests mediastinal pathology.
Normal Right Paratracheal Stripe Width on Radiography
The normal right paratracheal stripe measures less than 4 mm on PA chest radiography; widening suggests mediastinal pathology requiring further evaluation.
T
Normal Thoracic Lymph Node Size on CT and MRI
Reference guide to normal thoracic lymph node dimensions by location on CT and MRI, including mediastinal, hilar, axillary, and internal mammary stations.
Normal Thymus Diameter Size on CT by Age Group
Reference CT measurements for normal thymus diameter in children and adolescents, including anteroposterior, transverse, and craniocaudal dimensions by age group.
Normal Tracheoesophageal Stripe Thickness on Radiography
The normal tracheoesophageal stripe measures less than 5.5 mm on lateral chest radiography; thickening suggests posterior mediastinal pathology.
