MDCT images and The ACR Lung Imaging Reporting and Data System (Lung-RADS™) of Pulmonary nodules - Research in Hue National Hospital and Hue Medic Clinic
Main Article Content
Abstract
Objective: Solitary pulmonary nodule may be benign or malignant. The purposes of this study is to illustrate the clinical
characteristics, describe the images characteristics of chest X-ray and MSCT, classification of lung nodules by The ACR
Lung Imaging Reporting and Data System (Lung-RADS™) then offer management and monitor strategies for this disease at Hue
National Hospital and Hue MEDIC clinic.
Methods: The study design was cross-sectional descriptive. Describe the clinical characteristics and images of lung nodules
on chest X-ray and MSCT with LungCAD software to determine the nodular lesions during 1 year (5 / 2015-5 / 2016), in 2 centers
(Hue National Hospital and Hue MEDIC clinic).
Results: In our study, there was 49 patients with pulmonary nodules. Male was 38/49 (77.6%), more than female. Mean age
was 57 ± 2 years old. Smallest nodule is 5mm, average size is 18.7 ± 9mm. There was 31/49 (63.3%) patients with lung size
15-30mm. MSCT has higher sensitivity than X-ray in detecting nodules <6mm and ground glass nodule. Base on The ACR Lung
RADS classification, Lung - RADS 4B was seen most with 19/49 (38,8%) patients. Number of patients with Lung - RADS 4X was 8
(16.3%), including 5 patients who underwent surgeries, 3 of them had malignant pulmonary nodules.
Conclusions: Patients with pulmonary nodules should be evaluated by estimating the probability of malignancy, be performed imaging tests to characterize the lesions better, be assessed the risks and benefits of different management strategies (biopsy, surgery and observation with serial imaging tests). Lung - RADS classification is simple, easy to apply and make appropriate recommendations for the management of solitary pulmonary nodules.
