Role of Convex Probe Endobronchial Ultrasound in the Diagnosis and Treatment of Nonmalignant Diseases

Table 1

Comparison of RP-EBUS and CP-CBUS.

	CP-EBUS	RP-EBUS
Flexibility of bronchoscope for view	60°	360°
Real time TBNA Possibility	Yes	No
Doppler mode	Yes	No
Frequency of Ultrasound probe	5-12MHz	20MHz
Tissue Penetration	Low	High

A higher frequency leads to better resolution and image quality and less penetration and a low frequency in ultrasound waves leads to better penetration yet low quality image due to low resolution.
