Pancreatic pseudocysts (PPs) present a challenging problem for physicians dealing with pancreatic disorders. Their management demands the co-operation of surgeons, radiologists and gastroenterologists. Historically, they have been treated either conservatively or surgically, with acceptable rates of complications and recurrence. However, recent advances in radiology and endoscopy, have leaded physicians to implement percutaneous and endoscopic drainage (ED) into their treatment algorithms. Moreover, laparoscopic surgery, with its advantages, has become an attractive alternative choice when surgical drainage (SD) is required...

Advanced endovascular technology and techniques allow interventional radiologists to utilize novel ways of basilar artery recanalization in the setting of acute ischemic stroke, especially when routine approaches are not eligible. Several authors described nonstandard revascularization techniques in acute ischemic strokes due to basilar and middle cerebral arteries occlusions with full technical and clinical success. In this report, we present retrograde right vertebral artery recanalization using left posterior communicating artery for subsequent anterograde balloon angioplasty and stenting of a right vertebral artery ostium followed by full vertebrobasilar blood flow restoration...

Christopher R McAdams, Andrew J Del Gaizo
Scrotal pain is a common acute presentation for medical care. Testicular torsion and epididymo-orchitis are two diagnoses for which early detection is critical and their sonographic imaging features have been thoroughly described in the radiologic literature. Other important conditions for which radiologists must be aware have received less attention. This article will highlight key traumatic and non-traumatic causes of acute scrotal pain other than testicular torsion and epididymo-orchitis that may present in the emergency department setting...

BACKGROUND: Transpedicular screws fixation has a biomechanical advantage of improving fusion rates. In the posterior thoracolumbar immobilization, a large number of screws cause perforation to pedicle or vertebra body. Techniques as radiograph and CT were used to minimize this complication. However, ultrasound in detecting the pedicle breach during the placement of the screw in unknown. Our goal is to evaluate the sensitivity of ultrasound for detecting the breaches. METHODS: A B-type transducer was used for scanning 216 Titanium pins inserted into the cadaveric pedicle...

Recent literature shows that perioperative ultrasound guidance of surgery for palpable and nonpalpable breast carcinoma results in improved surgical effectiveness. Ultrasound-guided surgery can easily lead to significant improvement of the number of radical resections and can decrease the need for additional surgery or extra radiotherapy. Ultrasound-guided surgery also contributes to a reduction in the amount of excessive breast tissue removal, which means the final cosmetic result is better. Ultrasound-guided surgery is cost-effective and easy to learn...

Clinical post-mortem radiology is a relatively new field of expertise and not common practice in most hospitals yet. With the declining numbers of autopsies and increasing demand for quality control of clinical care, post-mortem radiology can offer a solution, or at least be complementary. A working group consisting of radiologists, pathologists and other clinical medical specialists reviewed and evaluated the literature on the diagnostic value of post-mortem conventional radiography (CR), ultrasonography, computed tomography (PMCT), magnetic resonance imaging (PMMRI), and minimally invasive autopsy (MIA)...
