In CT-guided transthoracic needle biopsy, the final diagnosis and lesion size affect diagnostic accuracy: benign lung lesions and lesions smaller than 1.5 cm or larger than 5.0 cm in diameter provide lower diagnostic yield.
The efficacy and safety of CT-guided FNAB is not significantly affected by the training level of the cytopathologist on-site. Moreover, the number of specimens obtained for each procedure is a risk factor for pneumothorax.
CS-MRI and DW-MRI are both useful tools for examining patients with MG. The SII is more accurate than the ADC to differentiate TLH and NT from THY (AUROC, 1.000 and 0.931, respectively). Furthermore, the ADC is a noninvasive parameter that could be used for distinguishing TLH from NT, which is useful in selecting patients for surgery because, for nonthymomatous MG, acceptable rates of complete stable remission after thymectomy are found in TLH but not in NT.
CT-guided percutaneous transthoracic needle biopsy is an easy, reliable and safe procedure that obviates the need for exploratory surgery in medically treatable or unresectable cases. It should be the first invasive procedure in the diagnostic workup of mediastinal masses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations鈥揷itations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
