Imaging of the spine is given a thorough update in this issue, beginning with an article on spine segmentation, enumeration and normal variants. Imaging of degenerative disease of the spine is then reviewed, giving consideration to appropriate utilization of imaging, specificity and sensitivity shortcomings in evaluation of degenerative disease, risks and benefits of imaging of degenerative disease, and the prevalence of radicular and xial pain and underlying pain generators. Next, the validity and socioeconomic impact of spine imaging in evaluating “degenerative pain syndromes is reviewed. Pathophysiology and biomechanics of disc and posterior element of degenerative disease is reviewed, along with imaging of radiculopathy / radiculitis, imaging of central canal stenosis, and imaging of discogenic pain (using MRI and discography). Imaging of joint related axial pain, spine neoplasm, spine infection, and non-acute trauma is also covered.

This issue reviews and updates a variety of topics in pancreatic imaging. Pearls on the Multiphasic CT of the pancreas are offered, along with the key MRI techniques for pancreatic imaging. Emerging CT, MR and US techniques for pancreatic evaluation (such as dual energy, DCMRI, spectroscopy, and US contrast) are elucidated. Ultrasound for pancreatic imaging is given a thorough review. An update on staging and resectability of pancreatic adenocarcinoma is discussed. Acute and chronic pancreatitis are reviewed, as well as cystic pancreatic lesions, congenital pancreatic anomalies, uncommon solid pancreatic neoplasms, and other pancreatic pathology. Post-operative imaging of the pancreas is discussed, and finally, an update on endoscopic techniques for the pancreas is provided.

This issue covers a wide range of topics related to genitourinary imaging, across a variety of imaging modalities. An update is given on dual-energy CT in urologic imaging. Imaging of the retroperitoneum is also discussed. Imaging of infectious and inflammatory diseases of kidneys is reviewed, as is imaging of the features of common and uncommon neoplasms of the bladder. Multimodality imaging of the ureter, unusual renal masses, and adrenal imaging are all addressed in detail. Finally, advances in pediatric urologic imaging are reviewed.

The practice of Emergency Radiology has undergone rapid change in the last decade: as imaging procedures are increasingly performed within short periods of time after the arrival of patients to the emergency room, the expectation for near real-time interpretations (often by subspecialists) has gained popularity. Larger emergency centers provide 24 hour on-site coverage by well trained radiologists, while others rely on the services of equally well trained radiologists located off-site, taking advantage of modern universal interconnectivity. Either way, radiologists’ input is increasingly affecting the immediate outcome of patients presenting with acute symptoms. Radiologists have embraced the challenge to protect patient safety by seeking evidence-based data to support the proper utilization of CT (including the use of alternative imaging modalities) and radiologists and CT manufacturers together have worked intensely to find optimal methods to deliver the inevitable radiation.
