Based on the positron emission tomography (PET) computed tomography (CT) image segmentation algorithm, this article explores the application of PET/CT in the recurrence and metastasis of thyroid cancer after differentiated thyroid cancer (DTC). ⋯ PET/CT and 131I scans are similar in the diagnosis of residual thyroid and lymph node metastasis, but PET/CT has more advantages than does the 131I scan in the diagnosis of bone metastasis and lung metastasis. PET/CT can still find other benign and malignant lesions, which is of great value in the restaging of DTC. The imaging effect of WBS lung lesions in older patients is not good. The presence of stripe, calcification, and patch shadows in the lungs is not conducive to the imaging of WBS lung metastases. Lung strips and calcification affect the WBS lung main factors for imaging of metastases.

Technical skill acquisition is an essential component of neurosurgical training. Educational theory suggests that optimal learning and improvement in performance depends on the provision of objective feedback. Therefore, the aim of this study was to develop a vision-based framework based on a novel representation of surgical tool motion and interactions capable of automated and objective assessment of microsurgical skill. ⋯ Automated and objective analysis of microsurgery is feasible using a mask region convolutional neural network, and a novel tool motion and interaction representation. This may support technical skills training and assessment in neurosurgery.

Graduate doctors' knowledge of central and peripheral nervous system anatomy is below an acceptable level. New technologies have been introduced to enhance education in the context of integrated curricula and reduced anatomy teaching hours in medical schools. However, it is unknown how varied this instruction has become between universities. This mixed methods study aimed to describe neuroanatomy teaching in medicine across Australia and New Zealand. ⋯ Results demonstrate widespread heterogeneity in the way neuroanatomy is taught to medical students. A standardized curriculum may improve collaboration between universities and facilitate translation of future research in the area into practice.

Direct visualization of the aneurysm neck and its related branches during microsurgical clipping of supraclinoid internal carotid artery (SICA) aneurysms using a standard pterional approach may be difficult, especially when aneurysms are posteriorly projected. We evaluated the efficacy and safety of an anterior temporal approach for clipping posterior-projecting SICA aneurysms. ⋯ The anterior temporal approach is safe and effective for clipping SICA aneurysms with posterior projection, with a high preservation rate of the related branches.
