The NELSON study: can optimisation of volume-doubling time cutoff decrease false-positive referrals for lung cancer?
In this retrospective study, patients underwent low-dose CT to determine whether optimisation of volume-doubling time (VDT) cutoff could decrease false-positive referrals for fast-growing nodules in lung cancer. 232 days seems to be the optimal VDT cutoff for the 3-month follow-up CT after baseline, with a reduction rate of false-positive referrals by 33%.
Key Points
- Lung nodules are common in CT lung cancer screening, most being benign.
- Short-term follow-up CT can identify ...
Shearwave elastography is a useful tool in addition to standard ultrasound
Shearwave elastography was used to determine elasticity characteristics of focal liver lesions (FLLs) in 108 patients with 161 FFLs. Significant differences in elasticity were found between focal nodular hyperplasias (FNHs) and adenomas, and between HCCs and cholangiocarcinomas.
Key Points
- Elastography is becoming quite widely used as an adjunct to conventional ultrasound.
- Shearwave elastography (SWE) could help differentiate adenomas from fibrous nodular hyperplasia.
- SWE could ...
