Hôpital Jean Minjoz in Besançon, France. "A conservative point of view would be to do a yearly CT-scan, which might be of interest over the long-term, however, doing regular scans every six
Lung cancer is considered more serious among other prevailing cancer types. One of the reasons for it is that it is usually not diagnosed until it has spread and by that time it becomes very difficult to treat. Early detection of lung cancer can signific
Medical imaging technologies have proven to be effective for pulmonary nodule detection and have been regarded as the procedure of choice for screening lung carcinoma. Many imaging devices have evolved depending on the different modalities such as CT, PET and MRI as mentioned above; each having its...
explained by the oxygen enhancement on tissue exposed to low doses. Within the higher doses, the radiation dose is a strong enough factor that the effect of ventilation is blurred. The CT-derived ventilation measurement has become increasingly utilized in radiation oncology for functional avoidance ...
[68Ga]Ga-FAPI PET/CT showed that FDG-avid lesions were also FAPI-avid (FAPI subtype not specified). No increased uptake in the muscles was observed, supporting the theory that this increased FDG-uptake was due to overuse of the right leg. Interestingly, the [68Ga]Ga-FAPI PET/CT scan ...

Table 4. Target registration error values for different conventional and deep learning-based methods on DIRLAB 4D-CT dataset. All results were extracted from the original papers, besides Voxelmorph* which was reported in Hansen and Heinrich (2020) and Voxelmorph** which we trained on the COPDGene...
Since recruitment, as precisely measured by thoracic CT scan, refers to tissue recruitment (i.e., amount of non-inflated tissue that reinflates at a higher pressure), the decrease in poorly aerated tissue and the increase in well-aerated tissue (which contribute to the end-expiratory lung ...
However, this is in large part explained by limitations in the NLST sample used for validation. The NLST validation data set was developed for purposes other than the current study and was not ideal for validation of prediction models. Sampling NLST scans matched nodules without cancer on size ...
The TRACERx study (https://clinicaltrials.gov/ct2/show/NCT01888601) is a prospective observational cohort study that aims to transform our understanding of NSCLC, the design of which has been approved by an independent research ethics committee (13/LO/1546). Informed consent for entry into the...
