The aim of the present study was to examine the usefulness and record the complications of preoperative lipiodol marking using computed tomographic (CT) fluoroscopy for the intraoperative localization of 107 pulmonary nodules. ⋯ Lipiodol marking under CT fluoroscopic guidance is a useful and safe procedure for the intraoperative localization of ground-glass opaque and/or small, deep, solid nodules.

Reported error rates for initial clinical diagnosis of idiopathic Parkinson's disease (IPD) against other Parkinson Plus Syndromes (PPS) can reach up to 35%. Reducing this initial error rate is an important research goal. We evaluated the ability of an automated technique, based on structural, cross-sectional T1-weighted (T1w) magnetic resonance imaging, to perform differential classification of IPD patients versus those with either progressive supranuclear palsy (PSP) or multiple systems atrophy (MSA). ⋯ These results demonstrate that a classification approach based on quantitative parameters of three-dimensional hindbrain morphology extracted automatically from T1w magnetic resonance imaging has the potential to assist in the differential diagnosis of IPD versus PSP and MSA with high accuracy, therefore reducing the initial clinical error rate.
