A wide range of clinically important anatomic variants and pathologic conditions may affect the renal vasculature, and radiologists have a pivotal role in the diagnosis and management of these processes. Because many of these entities may not be suspected clinically, renal artery and vein assessment is an essential application of all imaging modalities. An understanding of the normal vascular anatomy is essential for recognizing clinically important anatomic variants. An understanding of the protocols used to optimize imaging modalities also is necessary...

BACKGROUND: Moebius Sequence (MS) is a rare disorder defined by bilateral congenital paralysis of the abducens and facial nerves in combination with various odontological, craniofacial, ophthalmological and orthopaedic conditions. The aetiology is still unknown; but both genetic (de novo mutations) and vascular events in utero are reported. The purpose of present study was through a multidisciplinary clinical approach to examine children diagnosed with Moebius-like symptoms. Ten children underwent odontological, ophthalmological, obstetric, paediatric, orthopaedic, genetic, radiological and photographical evaluation...

BACKGROUND: Fibroepithelial lesions of the breast (FEL) are atypical lesions diagnosed on core-needle biopsy. The purpose of this study was to determine the rate at which FELs are upstaged to phyllodes tumor on excision, and to examine the clinical and radiological factors that may be predictive of upstaging. METHODS: A retrospective review from the medical records of patients diagnosed with FEL on CNB at a single institution between 2010 and 2015 was performed...

PURPOSE: Multi-phase post-mortem computed tomography angiography (MPMCTA) is a new diagnostic tool, used in forensic pathology. On the one hand, this technique allows a better and direct visualization of vascular and solid organ lesions. On the other hand, the invasiveness of the procedure-which requires surgical denudation (inguinal and/or cervical) and the insertion of surgical cannulas-leads to many relatives refusing scientific autopsies. Our hypothesis states that a minimally-invasive procedure combining interventional radiological techniques with MPMCTA (replacement of surgical cannulas by radiological catheters) will improve the approval rate of scientific autopsies by families...

Importance: The remnant liver after hepatectomy may have inadequate blood supply, especially following nonanatomical resection or vascular damage. Objective: To evaluate whether remnant liver ischemia (RLI) may have an adverse effect on long-term survival and morbidity after liver resection in patients with hepatocellular carcinoma. Design, Setting, and Participants: This study was a retrospective analysis at Seoul National University Bundang Hospital...

Sphenoiditis is of particular interest because the sphenoid sinus has thin wall and its special anatomical location facilitate dissemination of infection to many intracranial structures including vascular structures. The main objective of this report is to gain insight into patterns of presentation and imaging findings in cerebrovascular complications of sphenoid sinusitis and to emphasize the need of reviewing Brain Computed Tomography Scan in all windows. This is a report of 32-year-old young female presented with fever and headache who was diagnosed to have sphenoid sinusitis after radiological examination...

At least three major trends in surgical intervention have emerged over the last decade: a move toward more minimally invasive (or non-invasive) approach to the surgical target; the development of high-precision treatment delivery techniques; and the increasing role of multi-modality intraoperative imaging in support of such procedures. This symposium includes invited presentations on recent advances in each of these areas and the emerging role for medical physics research in the development and translation of high-precision interventional techniques...

Parallels in the evolution of x-ray angiographic systems and devices used for minimally invasive endovascular therapy Charles Strother - DSA, invented by Dr. Charles Mistretta at UW-Madison, was the technology which enabled the development of minimally invasive endovascular procedures. As DSA became widely available and the potential benefits for accessing the cerebral vasculature from an endovascular approach began to be apparent, industry began efforts to develop tools for use in these procedures...

PURPOSE: To characterize changes in radiation dose after introducing a new real-time image processing technology in interventional radiology systems. METHODS: Interventional radiology (IR) procedures are increasingly complex, at times requiring substantial time and radiation dose. The risk of inducing tissue reactions as well as long-term stochastic effects such as radiation-induced cancer is not trivial. To reduce this risk, IR systems are increasingly equipped with dose reduction technologies...

Lower gastrointestinal bleeding is most commonly associated with diverticulosis, ischemic colitis, vascular ectasia, and anorectal disease and less commonly associated with colonic malignancy. Infrequently, it is associated with mesenteric varices, a rare etiology that is not well documented in the radiology literature. We present a case of a 50-year-old man diagnosed as having intermittent left colonic bleeding from mesenteric varices due to a critical stenosis at the portal vein-inferior mesenteric vein confluence...

The concept of hybrid room was defined as an optimized surgical theater, offering the best compromise between asepsis criteria from standard surgical rooms and high quality imaging equipment from fixed radiological suites. This review aimed at summarizing what vascular surgeons should expect from hybrid rooms in daily practice and in the near future.

PURPOSE: This study aimed to determine the expression of angiopoietin-1 (Ang-1), angiopoietin-2 (Ang-2), and endothelial tyrosine kinase receptor (Tie-2) in central nervous system (CNS) hemangioblastomas (HBs) and explore the correlation with peritumoral cyst formation. METHOD: A total of 22 paraffin-embedded specimens derived from 11 cyst-associated and 11 solid solitary CNS HBs were collected for streptavidin-peroxidase immunohistochemical staining. The expression levels of Ang-1, Ang-2 and Tie-2 in cystic and solid HBs were estimated and compared according to the integrated optical density (IOD) of staining in the sections...

This prospective study was undertaken at a regional tertiary referral centre to evaluate the results of treatment of bone defects managed with the induced membrane (IM) technique. Inclusion criteria were patients with bone defects secondary to septic non-union, chronic osteomyelitis and acute fracture with bone loss. Pathological fractures with bone loss were excluded. Data collection included patient demographics, pathology, previous surgical intervention, size of bone defect, type of graft implanted, time-to-union and complications/reinterventions...

BACKGROUND: The use of antiangiogenic therapy in non-small cell lung cancer (NSCLC) requires thorough evaluation of patient characteristics in order to avoid potential safety issues, particularly pulmonary haemorrhage (PH). The aim of this consensus by a panel of experts was to identify important criteria for the selection of patients with NSCLC who would benefit from antiangiogenic therapy. METHODS: Radiologists and oncologists were selected for the expert panel...

The National Council on Radiation Protection and Measurements (NCRP) believes that the most critical need for the nation in radiation protection is to train, engage, and retain radiation professionals for the future. Not only is the pipeline shrinking, but for some areas there is no longer a pipe! When the call comes to respond, there may be no one to answer the phone! The NCRP "Where are the Radiation Professionals?" initiative, Council Committee (CC) 2, and this year's annual meeting are to focus our efforts to find solutions and not just reiterate the problems...

Midaortic syndrome (MAS) is a rare vascular disease that commonly causes renovascular hypertension. The lumen of the abdominal aorta narrows and the ostia of the branches show stenosis. MAS is associated with diminished pulses in the lower extremities compared with the upper extremities, severe hypertension with higher blood pressure in the upper rather than lower extremities, and an abdominal bruit. The clinical symptoms are variable, and recognition in children with hypertension can aid early diagnosis and optimal treatment...
