Value of focused lung ultrasound in diagnosing and monitoring pneumothorax after CT-guided lung biopsy.
Article in Journal of ultrasound, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPneumothorax is a common complication after CT-guided transthoracic lung biopsy. Pneumothorax is most often diagnosed with a conventional chest X-ray after a two-hour observation period. Ultrasound has been shown to be superior to conventional X-rays in diagnosing pneumothorax in some settings and it can be repeated without radiation exposure. PURPOSE: The aim of the study was firstly to explore the sensitivity and specificity of thoracic ultrasound compared to conventional chest x-ray following CT-guided transthoracic lung biopsy, and secondly to investigate the dynamic changes of pneumothorax size using ultrasound.
methodsThis prospective study was conducted at Odense University Hospital in the Department of Radiology. Adult patients undergoing CT-guided lung biopsy were eligible for inclusion. A total of 26 patients were included in the study and were scanned five times in sitting upright and supine positions during the two-hour observation time using the FLUS Protocol.
resultsPneumothorax was diagnosed via chest x-ray in 11 (42%) patients. With the patient in an upright position, the ultrasound had a sensitivity of 63.6% and a specificity of 93.3%. These numbers rose to 72.3% and 100% in the supine position. Monitoring the pneumothoraces showed a slight increase in size during the two hours.
conclusionsUltrasound can be used to diagnose pneumothorax after CT-guided lung biopsy. All pneumothoraxes that were identified by ultrasound were detected within the first 30 min. The dynamic changes of pneumothoraxes showed that the size of the pneumothorax did not increase to a level where the patient needed intervention or admittance.
