To propose an acquisition scheme suitable for fiber tractography without cerebrospinal fluid contamination while retaining high signal-to-noise ratio. ⋯ The combined DTI technique is capable of improving tractography with higher signal-to-noise ratio at shorter scan time than FLAIR DTI. Its superiority at thin-slice acquisitions makes it particularly suitable for high-resolution clinical applications.

The aim of this study was to evaluate the clinical value of virtual bronchoscopy (VB) in aiding diagnosis of peripheral lung cancer by transbronchial biopsy (TBB). In addition, we sought to systematically analyze the factors that affect the diagnostic sensitivity of VB-guided TBB for the evaluation of peripheral lung cancers. ⋯ Use of an ultrathin bronchoscope and simulation with VB reconstructed by high quality MDCT images is thought to improve pathological diagnosis of peripheral lung cancers, especially for solid and partly solid types. For small pulmonary lesions ≤30 mm, the lesion internal opacity is a significant factor for predicting the diagnostic sensitivity, and the sensitivity was low for small non-solid type of lung cancers.
