# Ultrasound Guided Biopsy among Patients with Lung Lesions Undergoing Procedures in Interventional Radiology of a Tertiary Care Centre

## TL;DR

This study examines how often ultrasound is used to guide biopsies for lung lesions at a tertiary care center and finds it is less common than in other studies.

## Contribution

The study provides prevalence data on ultrasound-guided biopsies for lung lesions in a specific tertiary care setting.

## Key findings

- Ultrasound-guided biopsies were performed in 14.89% of lung lesion cases.
- The prevalence is lower compared to similar studies in other settings.

## Abstract

Minimally invasive image-guided percutaneous core needle biopsy can obtain tissue samples for diagnosis of subpleural lung cancer, which is crucial for the correct management of lung lesions. Common complications of lung biopsy include pneumothorax, parenchymal haemorrhage and haemoptysis. The study aimed to determine the prevalence of ultrasound-guided biopsy among patients with lung lesions undergoing procedures in interventional radiology of a tertiary care centre.

A descriptive cross-sectional study was performed in the Department of Radiology and Imaging from 1 August 2018 to 30 September 2019 after obtaining ethical approval from the Institutional Review Committee. USG-guided biopsy of peripheral lung lesions was performed with an 18 gauge semiautomatic biopsy instrument and a 17 gauge coaxial needle. A convenience sampling method was used. The point estimate was calculated at a 95% Confidence Interval.

Among 188 biopsy of lung lesions, ultrasound-guided biopsies were performed in 28 (14.89%) (9.80-19.98, 95% Confidence Interval).

The prevalence of ultrasound guided biopsy among lung lesions is lower than other studies done in similar settings.
