Radiology: Chest CT study found predictors of COVID-19 pneumonia fibrosis

Studies have conducted in-depth studies on the qualitative chest CT findings of COVID-2019 pneumonia, quantitative chest CT (QCCT) methods and semi-quantitative lung severity score (LSS)
.

The typical chest CT findings of new coronary pneumonia include bilateral and multi-lobed ground glass shadows (GGOs), with posterior and peripheral distribution, with consolidation, thickening of the interlobular septum, and subsegmental pulmonary vasodilation (>3 mm)

The short-term and mid-term chest CT results of patients with new coronary pneumonia have been reported in a number of studies, including qualitative and semi-quantitative methods; fibrosis is a common finding that symptoms begin a few weeks later .
The long-term acute pulmonary sequelae of new coronary pneumonia remains unclear .

Analysis of CT qualitative performance, semi-quantitative lung severity score (LSS) and quantitative chest CT (QCCT) inflated lung

2020 On 3 March 2020, from 19 to 24 May, the new crown for medium and heavy pneumonia patients were prospectively followed up for 6 months

118 patients (62 women, average age 65 ± 12 years) had baseline and 6-month chest CT follow-up

Comparison of lung severity score at baseline and follow-up

(a) The ROC curve tests the performance of the baseline lung severity score in predicting fibrosis-like changes in chest CT during the 6-month follow-up.
The area under the curve (AUC) is 0.

The AUC value of the clinical model is 0.

The ROC curve tests the performance of clinical (blue line), radiology (green line) and combined models (orange line) in predicting the presence of fibrotic-like changes during a 6-month follow-up chest CT

In the 6-month chest CT follow-up, 72% of patients showed late sequelae: fibrosis-like changes were the most common residual manifestation (72%), followed by ground glass density (42%)
