Application of Ultrasonic Elastography in Lung Lesions

Elastography is an imaging of tissue elasticity or stiffness and is currently emerging as a mainstream tool for ultrasound-based diagnosis. This compressibility property of materials, mathematically expressed as the change in tissue displacement as a function of its distance from the compressing device, is known as strain and is the parameter that is imaged in an elastogram.

Elastography has currently shown promising result in differentiating viscoelastic nature of various organs, which is a consequence of certain underlying diseases.

At present, there are limited literatures revealing the application and feasibility of ultrasonic elastography in lung lesions. This is essentially important as it may serve as an adjuvant to B-mode ultrasound. The investigators aimed at exploring the application and feasibility of ultrasonic elastography on lung lesions.

About this study

Patients performed conventional B-mode ultrasound, subsequently followed by ultrasound elastography. The strain ration was measured and was compared between necrosis, atelectasis, consolidation and tumor.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

A. Inclusion Criteria:

Patients with radiographic findings of:

  • consolidation
  • obstructive pneumonitis
  • tumors

B. Exclusion Criteria:

  • Patients with poor acoustic window
  • Unable to hold breathing
  • Not cooperative
  • Presence of pleural effusion

Treatment and study plan

Primary outcomes

  1. Comparison of strain ratio between necrosis, atelectasis, consolidation and tumor

    Time frame: Up to 15 months

    The strain ratio was measured under ultrasonic elastography. At least three measurements were performed each time and we average all the measurements as the final strain ratio. Independent t test was used for comparison.
