Renal Ablation Techniques: State of the Art

OBJECTIVE: The purpose of this article is to describe the indications for and approach to image-guided percutaneous ablation of renal tumors. CONCLUSION: Image-guided ablation techniques have become accepted treatment of patients with small renal tumors, a viable alternative to partial nephrectomy. ...

Anatomy and pathology of the facial nerve

The facial nerve (cranial nerve [CN] VII) is a frequently overlooked structure on imaging examinations. Knowledge of the normal anatomy, embryology, and spectrum of abnormality will aid radiologists in correctly diagnosing lesions of the facial nerve. In this article, we review normal facial nerve anatomy, clinical presentations, imaging approaches ...

The purpose of this article is to describe the indications for and approach to image-guided percutaneous ablation of renal tumors. Image-guided ablation techniques have become accepted treatment of patients with small renal tumors, a viable alternative to partial nephrectomy. ...

CT of Normal Developmental and Variant Anatomy of the Pediatric Skull: Distinguishing Trauma from Normality

The use of computed tomography (CT) in clinical practice has been increasing rapidly, with the number of CT examinations performed in adults and children rising by 10% per year in England. Because the radiology community strives to reduce the radiation dose associated with pediatric examinations, external factors, including guidelines for pediatric ...

MDCT and MR Urogram Spectrum of Congenital Anomalies of the Kidney and Urinary Tract Diagnosed in Adulthood

OBJECTIVE. Congenital anomalies of the kidneys and urinary tract (CAKUT) encompass a spectrum of anomalies that result from genetic, epigenetic, environmental, and molecular signal aberrations at key stages of urinary tract development. CAKUT can be seen incidentally on cross-sectional imaging of the abdomen or can be a cause for adult-onset chr ...

Adult Cardiac Valvular Disease for the General Radiologist

Cardiac valve dysfunction underlies a large fraction of cases of cardiac disease. Many patients with heart failure or valve dysfunction present with nonspecific symptoms (eg, shortness of breath) and are evaluated with chest radiography or chest computed tomography (CT). In addition, patients with other diseases (eg, cancer) may undergo chest imagi ...

Proximal Femoral Fractures: What the Orthopedic Surgeon Wants to Know

Each year, more than 250,000 hip fractures occur in the United States, resulting in considerable patient mortality and morbidity. The various types of adult proximal femoral fractures require different treatment strategies that depend on a variety of considerations, including the location, morphologic features, injury mechanism, and stability of th ...

Tip-of-the-Iceberg Fractures: Small Fractures That Mean Big Trouble

Several small and seemingly unimportant fractures are associated with other more serious injuries, usually to adjacent soft tissues. The purpose of this article is to discuss 11 of these injuries, in each case describing the fracture (the tip) and the injuries that lie beneath the surface (the iceberg). Some fractures should be considered analogous ...

Review of Leiomyoma Variants

The purpose of this article is to review the clinical, imaging, and pathologic features of leiomyoma variants. Fortunately, most of these variants are rare and have a benign natural history, given currently there are no significant series to establish definitive clinical or imaging findings that can reliably distinguish among them. Although there a ...

Regional Articular Cartilage Abnormalities of the Hip

Imaging of hip cartilage is challenging because of its limited thickness and complex geometry and therefore requires advanced MRI techniques. However, cartilage abnormalities are found in a number of disease entities, and their diagnosis may impact patient management. This article will provide pertinent information about the motivation to image hip ...
