Filter by:The purpose of this study is to assess the feasibility of UHFUS on detection of GGOs in excised lung tissue and investigate UHFUS features of GGO in vitro. Each GGO was detected by palpation, UHFUS and open biopsy in sequence. The comparison of detection rate and time consumption were analyzed respectively. The Bland-Altman analysis was used to estimate the agreement of tumor size measured by CT, UHFUS and pathology.
Based on the previous review and research, we would like to further observe the nodule changes in patients with pulmonary nodules. These changes include factors such as the reason for the further enlargement or deterioration of the nodule, time, lifestyle, the patient's region, and hereditary medical history. At the same time, we will further look at the corresponding characteristics of a population that does not change the size and nature of the nodule, including age, gender, and all the factors discussed above. On this basis, we can propose more scientific methods for the treatment and management of pulmonary nodules, and provide a more reliable clinical reference for the clinical treatment of pulmonary nodules.
European lung cancer screening studies using computed tomography (CT) have shown that a management protocol based on measuring lung nodule volume and volume doubling time (VDT) is more specific for early lung cancer detection than a diameter-based protocol. However, whether this also applies to a Chinese population is unclear. The aim of this study is to compare the diagnostic performance of a volume-based protocol with a diameter-based protocol for lung cancer detection and optimize the nodule management criteria for a Chinese population.
Patients with lung nodules/mass found by CT (computed tomography) or PET (positron emission tomography) who agree to receive lung resection are arranged to test the dielectric property before receiving the frozen pathological examination. And the final pathological results are recognized as the standard diagnosis. Then the sensitivity and specificity of the dielectric property test will be evaluated comparing with the frozen pathological examination.
In patients with peripheral lung nodules, what is the additional diagnostic yield of biopsies obtained with flexible cryoprobes compared to standard techniques? For patients with peripheral nodules, we hypothesize use of the cryoprobe will allow larger samples of tissue to be obtained and therefore, will increase the diagnostic yield over conventional techniques
In recent years, more and more people are having lung CT scans performed to screen for various cancers. Many of them have small abnormalities detected, called "nodules", which - for a variety of reasons - doctors are unable to biopsy. As a result, many patients have their CT scans repeated on a regular basis to see if their nodules grow. This process can last several years. Many patients experience significant anxiety during this process, when they are aware of a spot in the lung, but are not told any specific cause. Researchers at Memorial Sloan-Kettering have developed a new way to look at lung nodules in three dimensions. The purpose of this project is to see if any change in the nodules can be detected sooner by this method than by traditional CT scans.
A CT scan is performed after a lung biopsy in order to detect a Pneumothorax. We postulate that CT is more useful than chest radiography
