The emergence of functional neuroimaging has dramatically accelerated our understanding of the human mind. The advent of functional Magnetic Resonance Imaging paved the way for the next decades' major discoveries in neuroscience and today remains the "gold standard" for deep brain imaging. Recent improvements in imaging technology have been somewhat limited to incremental innovations of mature techniques instead of breakthroughs. Recently, the use of ultrasonic plane waves transmitted at ultrafast frame rates was shown to highly increase Doppler ultrasound sensitivity to blood flows in small vessels in rodents...

Neuroendocrine tumors of the pancreas (pNETs) are a rare group of neoplasms that originate from the endocrine portion of the pancreas. Tumors that either secrete or do not secrete compounds, resulting in symptoms, can be classified as functioning and non-functioning pNETs, respectively. The prevalence of such tumors has recently increased due to the use of more sensitive imaging techniques, such as multidetector computed tomography, magnetic resonance imaging and endoscopic ultrasound. The biological behavior of pNETs varies widely from indolent, well-differentiated tumors to those that are far more aggressive...

B Joseph Elmunzer
Endoscopy has emerged as a mainstay in the management of pancreatic fluid collections (PFCs), representing an important advance in clinical medicine that has significantly improved the risk-benefit ratio of treating this complex patient population. While endoscopic pseudocyst drainage has generally supplanted surgical and percutaneous approaches, the optimal strategy for walled-off necrosis remains variable and multi-disciplinary despite an emerging trend from randomized trials favoring endoscopy. Although several issues pertaining to endoscopic drainage appear to have been settled - such as the use of endoscopic ultrasound - other pressing questions - including the optimal prosthesis and debridement strategy - remain unanswered, and rigorous investigation is needed...

Over the last few decades, fine needle aspiration cytology (FNA) has emerged as a SAFE (Simple, Accurate, Fast, Economical) diagnostic tool based on the morphologic evaluation of cells. The first and most important step in obtaining accurate results from FNA is to procure sufficient and representative material from the lesion and to appropriately transfer this material to the laboratory. Unfortunately, the most important aspect of this task occurs beyond the control of the cytopathologist, a key reason for obtaining unsatisfactory results with FNA...
